Oil Leak 5.7 Hemi

Hello,

Anyone experience rear main seal leak?

The back of the oil pan is wet and I can't seem to find the leak from the rear of the engine.

There is a "flange" on the rear of the oil pan, but not sure of a seal.

Thought I would ask if anyone has any ideas...

Thanks,

you sure it's oil? The leak can start at one spot but show it's self in another. You need to get in there and really track it down. How bad is the leak? does it puddle under the Jeep?

A rear main seal leak usually collects and drips from the Bell Housing of the Transmission.

The new kind of rear main seals they've been using in every engine designed since the 90's, last much longer and leak far less than the common rear main seal leak of years ago.

Like with any leak, clean the engine and compartment real well and keep going back looking for the leak where it starts. Leaks can be decieving because the fluid will always down, collect and drip from the lowest point. So where you see oil collected is NOT always the location of the leak, its just where the fluid is collecting as it runs down the engine.

nearly 78K miles on our HEMI, no oil leaks thus far; though, transmission oil pan gasket and casing leaked under 'extended warranty' coverage (approx 62K). It's been pretty flawless other than that.

It has a drip about 6-8,000 miles. I drop the skid plate and clean it every other oil change. 41K miles on the engine.

I did have the PVC valve leaking once, but I don't see it wet anymore.

Guess I will just keep hunting. I know the newer plants use seals vs the old gasket but can't finger this small leak.

Thanks anyway.

OUT!

Well I don't have the hemi, but the jeep has now given me another surprise. I am leaking oil between where the engine and trasmission bolt together. Based on the general location, i'm thinking it's a rear main seal. I'm not really happy about it, only have 81,000 on the jeep. Anyone have an idea on what is the cost of fixing something like this? I'm assuming the transmission would have to be removed in order to replace it. And what about the bars stop leak for rear main seal?
