    Your question is not very clear.
    First off, is this manual of automatic transmission.
    Please explain better what you mean by main oil seal?
    Where exactly is the oil leaking from?
    If you're talking about the engine, are you talking the oil pan seal, front crankshaft, rear crankshaft oil seal? Engine Cover? I can help you.

SOURCE: Rear Main Seal Leak

THat seems to be in the ball park. If you have an AWD, the flat rate time is 14.4 hours. If you have just a FWD, it is 9.5 hours. In either case, the transmission has to be removed from the vehicle to access this seal. Sorry.

SOURCE: Rear Main Seal Leaking

Hello, it's not "easy" but, it's doable.
You'll need to follow the instructions and don't take shortcuts. ask for help if you need it.
Use this link to get an idea of what is involved. Ignore the "remove transmission" part. It can be done without removing the tranny. If you decide to do this buy a service manual to help you. If you have any questions feel free to ask.

SOURCE: rear main seal leaks..does this affect transmission??

A leaking rear main seal will not cause your transmission to leak.

The transmission has its own seal and should not leak because of the engine rear main seal.

Due to the labor involved in replacing the rear main seal on the engine, it is best if you replace the front transmission seal at the same time if possible.

Installation varies on different vehicles but the principles are the same.

i had the same problem and it turned out to be the gasket on the rear main seal housing not the rear main seal.

I have done many the transmisson has to come out to replace it but your price is way out of line, should not be more than $400.00 give me a zip and I can get you a certified shop that can do it for less with a warrenty.

I have a 2004 Toyota highlander leaking oil, oil light comes on. Could it be the rubber rings?


a 2004 toyota highlander V6

this should be your engine type
The 2GR-FE is a 3.5 L (3456 cc)

if leaks are that bad
always check the engine oil level before you drive off

fixing oil leaks on motors
degrease whole motor top and bottom

start with replacing the oil sender it may be the cause of the oil light coming on
after degrease
lay cardboard or paper under the car
take out for a drive and park over the paper over night

this pin points most of the oil leak locations
leaks from a V6 motor
rocker covers/ spark plug tube 0 rings.engine seals
cam seals
front and rear engine seals leak often
sump gasket can leak

if oil consumption or light on continues
can be a failing engine oil pump
or worn main bearings giving low oil pressure to the whole engine
you could be burning oil from worn piston rings
or hardened valve stems

a mechanic can fit an oil pressure gauge to the motor when hot
to check running oil pressure to confirm low oil pressure

if engine is worn out

it is possible to fit a lower mileage used motor to your highlander
its often cheaper than and engine rebuild

05 malibu leaking oil from rear of engine


This may be from excessive pressure in the sump from blow-by from the compression process . It is from a blocked PCV valve that is not equalising that pressure. I have also known oil leaks to happen because the rear main bearing cap is leaking oil past the join around the bolts (loose) or no sealing compound used in assembling the rear main bearing.. I would look at the PCV valve as it is the cheapest test first.. Check that the oil is not coming from the front gear box seal or torque converter seal.

Oil leaking from toyota camry 1992, 1994 model


You don't say what engine it has. The 4-cyl was a better than the V6 for oil leaks.

The V6 had oil leaks from

-rear bank cam cover gasket

-distributor o-ring seal

-oil filter bracket o-ring seal

-crankshaft nose oil seal (less common)

-rear main bearing oil seal (expensive, just leave it)

The 4 cyl leaked oil from

-distributor o-ring seal

-camshaft cover gasket

-rear main bearing seal (expensive, leave it)

Hi i have a 1994 dodge caravan it is leaking oil can this be fix im worry that we would have to save money for a van for my kids thanks


The Chrysler minivan products all had leaking problems. I have had 5 or 6 different Dodge or Plymouth minivans from 88 to 99. How bad is it. The most common thing is Valve cover leaks. Front and rear seals in the engine leak as well as the oil pan gasket. If its leaking a little bit at a time open the hood and look at the front and rear of the engine. Do you see grease and oil that has gone down the sides of the engine? Do you see a lot of grease on the engine with some clean streaks going through it. You may be able to see where its leaking from. If you know someone that knows what their doing have them change the leaky gasket/s. If not you can probably have it repaired for less than buying another van unless other things are seriously wrong with the van.
Hope this helps... Dale

I have an 83 silverado short bed and im about to pull the tranny out to get it rebuilt and the rear main seal may be leaking as i put oil in and it leaks out pretty fast. my tranny is covered in oil and so...


I'm fairly certain that your engine does not have a full circle external main seal (if when you remove the trans and flywheel you find the rear crank flange is bolted to the crank and not part of the crank, then I'm wrong) If it's not an external seal, it is two piece, located in the rear of the main bearing cap. That makes it necessary to remove the engine oil pan and the rear bearing. Before contemplating doing anything with that, make very sure that the leak is not from the intake or valve covers first. Otherwise you'd be doing ton of work for no reason. Wipe everything down and look carefully. If it's leaking fast it shouldn't be difficult to see.

Need a engine diagram for a 2.8 ltr v6 showing rear main seal


Just a little advise before you jump to thinking the rear main seal is leaking. The vast majority of the oil leaks from these 2.8L motors are the rear intake manifold seal and the distributor o-ring. I would check them first. The rear main seal is in the lower rear of the motor, you have to remove the transmission to replace ti.

Replaced rear main seal on 5.7 but still seems to be leaking. Any suggestions?


Be sure it is the rear main seal,there is a cam plug that could be leaking,but if it is the rear main oil seal leaking,then I suggest removing it,and installing a rear main repair sleeve,this will give it a new surface to ride on,the crankshaft may have a groove cut into it from the oil seal,this will remedy the problem.If this was at all helpful,please rate,thank you.

I have a oil leak on my 1990 buick skylark 2.5 motor coming from the back side of the motor i replaced the oil pan gasket the sending unit what could it be and how can i find it


I've had the same problem on other GM V6 motors. You need to have the rear main seal replaced to fix the leak. GM was notorius for oil leaks in those motors since the mid-80's and never did anything to fix the problem.
