Hi
|
Flywheel Seal on a 3.2
There seems to be a lot of oil behind the flywheel seal, is this normal? Or is there a seal behind this seal that's bad?

Youre into the main pressure to the crank oil galley. Seat the new one well.

That is a bad leak.

I had a similar leak problem. After carefully replacing the flywheel seal, I noted that the oil was also seeping from the top of the engine. In particular the oil breather and associated sensors etc. Replaced those seals also, and problem solved. Problem of course with oil, it will travel everywhere. Since you're at the back of the engine anyway, it's easy to replace the other seals on top - preventive maintenance if nothing else too.
Good luck. |

99% sure that's the leak I'm going to see when I drop my engine. Rebuilt it a year ago or so and have oil in that same area on the outer part. I was really careful about the installation too. IIRC the seal should have been slightly "proud" of the surface, which mine was. Maybe this time I'll put it flush. I also recall checking and confirming the inside was very smooth and no grooves or surface nicks so I thought it was seating against a good surface.
What I don't get it how does all that oil get up on the sides, outside the enclosed area where the seal is.

Be sure to get the seal from our host, I bought one from car quest because I didn't have the correct one, it was a "National" which is a good brand, anyway I didn't like the way it installed but went ahead, to make a long story shorter I ended up dropping the engine again and replacing with seal from Pelican, no more issues. Also on the top "trio" I found the green "O" ring seals best on the oil thermostat.

Examine the crankshaft where the seal edge sits.
If there is a groove in the crank...you might have trouble getting a new seal to do its job. I have had good luck with multi-edge seals in this type of situation (a seal with more than one sealing ring). They can be of the same depth...but have more edges to seat against the crank. Also...some of them have an outward facing dust shield (to keep dust and grime out so that it does not "grind" the crank). Hope this helps. Bob
