View Full Version : How difficult is it to replace the frot and rear engine seals?

08-08-2004, 03:50 AM
I'm rebuilding the tranny, and while I got it out, I'd like to try and repair the leaks...

I'm pretty sure its leaking from both, but not much, but makes things messy under there...

Can I replace either of them without reoving the oil pan?

Thanks guys!

The actual seal replacement is pretty straight forward; find a way to pry the old one out withoug damaging the crank.
You'll have to remove the tranny, clutch and flywheel to get to the rear seal.
You'll have to remove the harmonic balancer to get to the front seal. However, the stock harmonic balancer is pretty much a one use item (as is the crank bolt that holds it on). The aluminum inner sleeve of the balancer is forever deformed when originaly pressed on at the factory. If you re-use the balancer it will likely break withing 5 - 10k miles.
Then again if your car has many miles on it, you'll want to put a new one on anyway to be proactive. An aftermarket solid steel alternative exists, and can be re-used.
