Need some help with my 1990 pontiac firebird its a 3.1l v6?

i know the rear main seal is leaking and also the oil pan is leaking but does anyone know how i can change them both without removing the engine completely?i mean could i unbolt the transmission and loosen the motor mount bolts just enough to separate the two and get the oil pan off?

Need some help with my 1990 pontiac firebird its a 3.1l v6?
just loosen the motor mounts, raise the engine part way, take off the oil pan. now, do you know how to change the rear main seal?if you don,t then i,ll tell you how. take the last main bearing out, take a thin screwdriver and where the seal is above the crank, tap on the seal to get it started and take a pair of needle nose pliers and pull the upper half out( watch you don,t scar the crank). now take the other part of the seal out of the bearing cap, when you get a new seal ask for the rubber one, it,s better then the rope kind. take the new seal and oil it up (so you wont get a dry start up), start the seal above the crank with the lip facing the engine. now take the other half of the seal, oil it up and put it in the bearing cap with the lip facing the engine, dry the ends of the cap and engine block off and put some high temperature sealer(the blue is the best) on the ends of the bearing cap where the ends of the seal is at, put the cap on with both lips facing together and torque the bolts, put the oil pan back up on with a new gasket, let the engine back down and tighten the motor mounts. fill it up with oil and your on the road again.Need some help with my 1990 pontiac firebird its a 3.1l v6?
You do not have to separate the transmission from the engine to replace the rear main seal. Simply remove the tin cover from the bottom of the torque converter and drop the oil pan. Two bolts are on the bottom of the rear main bearing which need to be removed. The two piece seal spins out from the top of the exposed crankshaft.



It may be necessary to drop the exhaust pipes from the exhaust manifolds for clearance purposes.

Where is my 2005 Accord EX V6 vibration coming from?

Ok, so for starters this is NOT your typical %26quot;Oh, its a brake problem%26quot; or %26quot;Oh, you need a wheel balance%26quot; vibration - kinda tired of seeing those posts with only those solutions.



My car has several mechanics stumped: Honda dealer, Sears, and another auto shop all can't figure it out.



So, of course we did the obvious least expensive fixes first: balance, alignment, changed tires (twice), and checked rims - they are not bent. Then used a device called %26quot;chassis ears%26quot; which were kind of fun to drive the car with while listening to different parts of the car - but no sound changes when hooked up near the brakes and motor mounts and another part - I forget what it was called %26quot;lower....something%26quot;



Decided to change anyway all the brake pads and rotors and then front axles.

Still, vibration.

Tired and worn out from this. Looked up recalls on 05 Honda Accords and there's several but I don't see how any of them would cause the vibration. There's also no indication of body work from the previous owner (bought from dealer who received the car after a lease was up).



I've heard that automatic transmissions sometimes have these vibrations and the whole thing would need to be changed out if that is the case or it could be the %26quot;harmonic stabilizer%26quot; that's attached to the camshaft. But that hasn't been decided to explore those 2 yet to see if they are the problem. I guess it's a little more expensive to do that.



Oh, and another thing, the vibration comes on stronger with colder outside temperatures (but still is present when it's warm out but less pronounced).

And also, lubing up the metal holders for the brakes (these metal holders clip onto the brakes which clip onto the calipers) helped out too, but only for a half day on a warm day too- so that's why I still thought the brakes might be a problem and changed them out.



Thinking of just trading in for something else, maybe BMW, Lexus, Ford, Mercury or something.

Would I tell the dealer that there's a vibration? Kind of feel I should but....?

Maybe just go back to the original dealer (Herb Chambers) and trade in for one of their cars but I didn't like my auto purchasing experience there with this Honda and don't want to go back to any of them.



Any thoughts on any of this?Where is my 2005 Accord EX V6 vibration coming from?
You need to start with a better description of what the vibration is that you are trying to fix.



1) does the vibration only happen when the car is in motion or do you feel it at stops as well?



2) if only when the car is in motion, at what vehicle speed does the vibration start to come in?



3) at what engine speed does the vibration start to come in?



4) what gear is the transmission in?



5) does the vibration change with vehicle speed, engine speed, or transmission gearing?



6) is the vibration felt on turns, straights, uphills, downhills, or under all conditions at the threshold speed?



7) where do you feel the vibrati0on? In the seats? In the steering wheel? in the accelerator or brake pedal?



8) does the vibration go away when coasting in neutral?



9) is the vibration felt on transmission shifts, or before, or after the transmission shifts? does the intensity change?



10) what is the engine temperature when the vibration occurs? cold, hot or at all temperatures?



11) has the dealer determined the order of the vibration? do they know the resonance of the vibration in Hertz? do they know the amplitude?



12) is there an audible noise with the vibration or is the vibration just felt?



these are only a few of the questions that you need to provide data on before you can expect anyone to narrow down the possibilities. the more information you give the better the chance you have of someone isolating the vibration.



hope that helps.Where is my 2005 Accord EX V6 vibration coming from?
stop going to a dealer first thing most of time of trouble shooting go to a real shop place that works on cars dealership sale cars and only work on new cars where shop repair car every day sorry best bet to find a problem wil be a better shop not a dealershipWhere is my 2005 Accord EX V6 vibration coming from?
It could be a front axle (drive shaft).

How much work is it to change head gaskets on a front wheel drive fuel injected engine?

Rhetorical question: a whole lotta bucks -- usually 1,000.00 plus, down down. More if it is a frontwheel drive sideways mounted motor.

Pull the spider %26amp; the fuel control, all othr **** cluttering top of engine, get the intake off, remove bolts from exhaust manifolds, untorque %26amp; remove head bolts. Now come parts. Reinstall in reverse.



How much work is it to pour a tube of aluma seal into radiater? About 5 minutes %26amp; 5$.

Is it guaranteed to fix your leak? No, but it's got a good track record.

Has it ever %26quot;clogged%26quot; (haha) an engine up? No documented cases -- it bonds, not clogs SMALL cracks %26amp; holes.

Have I used it? Yes, mostly on the Ford Taurus w/ 3.8 %26amp; history of leaking head gaskets. Success? Interemittent. Damage? None. Could I have made more money saying %26quot;dude, I'm going to need to charge you minimum of 1200.00$ max of 1600.00$? Ha! %26quot;Think about it.%26quot;

Are you asking a question or making a statement that you are looking for validation of your actions? Myself, I would Truly be disappointed if you were my mechanic and I would be looking else where for a mechanic that I could have faith in. It is just this type of shady workman ship that gives good techs a reputation that has to be over come by good deeds. You say more than 18 years, well I say more than 43 years and I enjoy doing my job the right way the first time every time.

Rhetorical answer: In a whole lot more years than 18 repairing automobiles, I have never found any magic solution that will %26quot;repair%26quot; a blown head gasket.

My honest opinion? You'd be doing your customer a greater service by replacing the head gasket if the customer plans on keeping the vehicle for any significant length of time.How much work is it to change head gaskets on a front wheel drive fuel injected engine?

radiator sealant clogs up the veins in the radiator. these veins as u know are already small ports running from side to side in the radiator to cool the water.. it also adds deposits to the engine and waterpump and can sometimes collect around the thermostat.. if your looking for a quick fix until u can repair your vehicle youll end up replacing more parts in the end,, if your loooking to just fix and sell and not care what happens to the next guy then your on the right track..

i charge 350 labor plus est 100 in parts (gasket/oil/coolant) and 50 per head to local machine shop to pressure test and resurface.., usual total cost to customer is under 700,, any engine... besides northstars.. fix it right man,, Art

I'm pretty sure that a one year unlimited access/download for one vehicle is right around $25.00.



They do run promotions so you may get lucky, my last re-activation was $12.95



A word of caution: I run a Car Repair Ministry out of my church, and have, on occasion, been forced to purchase a manual from one or another auto parts stores.

I have found so many COMPLETELY wrong procedures, some even with pictures, that you will need to be Very cautious when using them; particularly when it comes to lining up timing marks for a belt.

The few extra dollars for ALLDATAdiy is easily worth the avoided problems.

Not right off-most businesses that have that info, have paid for it, and sell service manuals with pics and text included. Most auto parts places will have a book for you, about $15 or $20.Auto repair?
You can usually find that info at the local library in the %26quot;reference%26quot; section... You can't check these books out, but you can copy what you ned from them...

2000 camaro oil pan gasket leak?

so from 1-10 (10 being the hardest) how hard is it to change an oil pan gasket leak on my camaro. i was told i had to lift the engine a few feet. ( so would i have to loosen the motor mounts or what?2000 camaro oil pan gasket leak?
my best advice is to make damn sure it's the oil pan gasket and not the intake manifold gasket or something else up top leaking and running down the ends of the block. I just read the service manual procedures and it looks like for both the 3.8L and the 5.7L you pretty much have to drop the engine cradle down to access the oil pan. Not to mention that they use RTV sealant on both sides of the new oil pan gasket so chances are you are going to get RTV all over everything. And if you have any oil anywhere the RTV goes, it won't seal and you'll be doing it all over again. So make sure it's the oil pan gasket leaking. On a scale of 1 to 10, I'd give this an 8.2000 camaro oil pan gasket leak?
Could be close to a 10. If you are lucky you can lift the engine maybe 12 inches or so. That would probably mean taking your exhaust loose and wires too in order not to break them. It would prefer just taking the engine out. That way you could do the job right the first time.2000 camaro oil pan gasket leak?
autozone.com has a online repair manual with step by step instructions and diagrams to help you... it should not be hard if you follow directions2000 camaro oil pan gasket leak?
Try to tighten each bolt uniformly slightly tighter. You could use a torque wrench. Then see how fast it still leaks. A slow leak may be acceptable.2000 camaro oil pan gasket leak?

Do I have the ability to fix broken timing belt on a 1994 escort (1.9 motor)?

I am somewhat mechanically inclined... I know I need to support the motor and remove the motor mount which I think all I need to do is remove 2 bolts attached to back of motor and the long bolt that runs through the rubber bushing attached to the frame... (hope that is correct).. My biggest concern is if I am working on it by myself, when I line up the timing sprockets, how do I determine top dead center for the number one cylinder? I know how to line up the crankshaft pulley according to the teeth and the vr sensor, after that I am a bit lost on finding top dead center for the number one cylinder. I have changed timing belts before but not if they had broke while running, I would would just make sure I didn't move any of the pulleys when replacing... This belt broke while running and I am concerned that I may not be able to line it all up...any advice will be helpful-Thanks-LeeDo I have the ability to fix broken timing belt on a 1994 escort (1.9 motor)?
As far as telling if you are at TDC on the end of the compression stroke/beginning of the power stroke, besides lining up the timing marks, you have to make sure that both valves for the 1 cylinder are completely closed. If it were on the end of the exhaust stroke/beginning of the intake stroke, at least one if not both of the valves would be slightly open.



Here's a diagram to help with locating the marks;

http://repairguide.autozone.com/znetrgs/



And I would recommend a new water pump, unless you are sure it has been replaced recently. Also a new tensioner.



As far as the interference fit issue, you're in luck there. The 1.9L is not an interference fit engine. That was the 1.6L SOHC in earlier Escorts that were a big shock to their owners wallets, back in the day.Do I have the ability to fix broken timing belt on a 1994 escort (1.9 motor)?
Go to your favorite home depot type store, and buy a very long, thin wooden dowel. Take out the spark plug from the 1 cyl (all of them if you don't want to fight the engine compression). Put the dowel in there. Now when you're rotating the engine you can see the position of the piston by the motion of the dowel.



Now, some engines have matchmarks for TDC. Not having done a timing belt on your particular engine I'm not sure what the matchmarks look like. And they also may be covered in grime and general engine crap. If you can find them (usually small dimples on the pulleys), line them up with the %26quot;zero%26quot; (or another dimple) on the block. This is a lot easier than the dowel method, but finding the matchmarks can be a real PITA on a dirty engine.Do I have the ability to fix broken timing belt on a 1994 escort (1.9 motor)?
Well, I would not bother to repair broken timing belt.Sad to tell you but when your timing belt break while running the car the inside motor has broken down meaning a new motor. SorryDo I have the ability to fix broken timing belt on a 1994 escort (1.9 motor)?
You need to find out if you have an interference motor before you do anything. Call the dealer. If it is an interference motor you will have bent valves and need a valve job which requires removing the cylinder head.

If you don't have an interference motor, just set the crankshaft pulley to the TDC mark. Then align the camshaft timing mark. Check all the pulleys to see if they feel dry by spinning them by hand. Replace them if they make noise or don't feel smooth when spun. Check for leakage at the water pump, you might consider replacing it if you have over 80,000 miles on the motor.Do I have the ability to fix broken timing belt on a 1994 escort (1.9 motor)?
Why did you wait so long???? These are an interference fit engine. Ordinarily, a few hand tools and a Haynes manual would have gotten you through this cheaply. Or ALLDATA data base found in many libraries. If you are lucky, you didn't bend a valve. If you are UN-lucky, you will have to remove the head and have a new valve or two installed.

How do i swap a b18c1 gsr engine in my 91 da integra?

Right now i have a 91 acura integra with a b18a1 motor with a tanabe concept g exhaust and intake. I blew my head and now i have bad compression in some of my cylinders. im lucky im still able to drive it. I want to swap the stock motor with a b18c1 gsr motor.



and my questions are:



1. Would i need to change my mounts?

2. What would i need to keep from my original motor? (i.e. wiring harnesses, ecu, etc.)

3. Would i be able to keep my exhaust with the swap?

4. Do you think its a good idea to go ahead with this swap? or should i just buy a rebuilt b18a1 engine and build that up?

5. Is there anything else that i should know about with going through with this swap?How do i swap a b18c1 gsr engine in my 91 da integra?
1.. no you can use your stock mounts.



2.. keep your harness, and clutch if your not gonna replace it, keep it around for spare parts you might need... sensors ect



3.. yes, but not your header.



4..if you have the money to spend then yes the gsr is a much better motor.



5..i'd suggest converting to obd1 and using the p72 ecu. also in the future or right now if you have the money get a b16 or gsr trans, the ls trans sucks and you'll notice a big difference with a shorter b16 trans.How do i swap a b18c1 gsr engine in my 91 da integra?
every thing he said but if your going to use your obd 0 harness... you would need to route a vtec line and use an obd 0 b16 ecu
