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.

SOURCE: Rear engine oil leak....

Oil leak can be attributed to several factors.
1. Gasket failure.
2. Uncontrolled Crank case pressure Failure.

RECOMENDATION:
Tighten both the valve cover and oil pan bolts.
Replace the Positive Crankcase Ventilation Valve and vacuum line.,

INFO: PCV
This is a valve causes a negative vacuum on the engine while its running, As to say if it had a leak in a valve cover it should not be leaking while its running, only when the engine it turned off.

Hope this tip guides you in the correct direction to solve this problem.

Why would I have oil in where my flywheel is and
Give more information. What car, what year model? If there is oil where the flywheel is, chances are you have a leaking rear main bearing oil seal or leaking gear box primary shaft oil seal. Coil packs? They should be there to make the car go.

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 leak front engine timing chan
1995 Tracker would have a timing BELT. Normal oil leak points (in order) on a Suzuki G16 engine are the distributor base (rear of motor), valve cover (top of motor), front main seal (behind lower timing belt cog) cam seal (behind the upper timing belt cog) and rear main seal. (behind the flywheel). I'd suspect the front main seal or cam seal. I use foot power to help find oil leaks.

Oil leak on driveway coming from front of engine

Dear Sir,
Here is the oil leaking Problem Identifying Technique

Engine oil leaks from the valve cover gasket are common.

  • The intake manifold plenum gasket may leak and cause increased oil consumption/burning and a spark knock during acceleration; the gasket should be replaced.
  • External oil leaks from valve cover gaskets, intake gaskets (front or rear), and the rear crankshaft (rear main) seal area are common. The rear main seal is an unlikely source. Normally, the bearing cap mating surfaces (as well as the sealing surface between the oil pan and bearing cap) are the source for the leaks.
  • Engine oil leaks at the distributor can be misdiagnosed as leaks from theintake manifold seal, oil pan gasket, or rear crankshaft (rear main) seal. A revised distributor is available if oil is found inside the distributor.
  • If the oil filter casing shows signs of distortion from excessive oil pressure, theoil pump should be replaced.
  • Often misdiagnosed as a leaking oil filter gasket, the oil filter adapter can seep from between the adapter and engine block.
  • Carbon buildup on the top of the piston is common. As the buildup increases with mileage and over time, symptoms may vary from light ticking, to ticking/hammering, to hammering/knocking noises. Fuel injector cleaner often solves the problem.

    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)

    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.
