Oil Leak

[Bob K]

I have an '04 and at about 96,000 I took it in because of a small leak at the rear of the engine. Ford said it was the rear main seal and replaced it. It still leaked so I took it back in and they said they replaced the seal again. What surprised me is that they said it was an easy job. I saw no evidence that anything had been worked on at the rear of the engine.

I now have 113,000 on it and it still leaks. Just little spots in the driveway. In Florida we have a lemon law and I'm entitled to arbitration if they refuse to fix it again. Is this small leak something that can get much worse in the future? Is it worth the hassle.

Hey man If you can get them to fix i would it def will not fix it self, those 6.0 have an adapter on the back of the engine to fit the ford transmissions cause they are an int. Motor if its not perfectly in place it will always leak no matter how many seals you put in it. I would def have them fix it if they still will.

Thanks Dieselmann. If they refuse I can take it to binding arbitration but if it's going to continue to leak is it worth the trouble?

I will just say of the 184 6.0,s we have in the fleet we have changed only 1 oil seal in the 3 yrs I have been working here. Now 6.0's do leak a lot up top in the valley and does tend to run down to the back edge of the engine.

When you do change an oil seal ya best bet is to change the houseing gasket and the back plate gasket as well.

Is it a big deal to change the rear main seal? They said they did this and it was not a difficult job. How do they do this without dropping the pan? I saw no evidence that they did anything.

The rear seal is a one piece seal that fits in a houseing that bolts to the back of the engine. You dismount the transmission, pull the transmission back remove the flexplate and there it is. No need to remove the pan anymore so it does make it a lot easier.
