Front cam/crank shaft seal replacement

Postby aahmes57 » Thu Feb 24, 2011 6:16 pm

I'm leaking oil again.

I can't seem to find a good write up w/ pics for the front cam/crank shaft seal replacement.

Does anyone know if good DIY repair is out there somewhere?

Thank you

The front seals are difficult to remove and replace due to the proximity of the front of the camshafts to the strut tower and the ECU box on the exhaust side and intake side respectively.

One other potential snag is the adjustable cam timing. The cam sprockets have slotted bolt holes and they can be adjusted. In my case I used some spray paint to mark the bolt positions so that I could get the timing on the sprockets back to their stock positions.

Hey guys,

Is it the consensus here that the FRONT CRANKS seal never leaks (it is part of the Oil Pump BTW)?
If so, then I won't bother with it during the next TB change at 120K.

If it's leaking, you likely need to change it. If it's not leaking, leave it alone.

Well,

The reason I ask is that: while I am there (replacing the TB) I may as well do the Crank Seal as I don't want to do the job twice.

However, if people tell me they don't ever have a leak from the Front Cranks Seal, then I won't bother.

Again, if it's not leaking, leave it alone. The timing belt is a 2 hour job, don't turn it into a 5 hour job messing with a seal that's not leaking. You would have to remove the crank, likely the starter, which would include the manifold, get the picture? You can do those seals and get t-boned next week. Don't fix what aint broke.
