Re: rear main seal

the tranny, clutch, and flywheel all need to come off. All that work and it only takes about 5min to change. But its not that bad.

Re: rear main seal

Wait a minute...

Before you start tearing everything apart, take a mirror, and look at your intake manifold end seals. They are prone to leak oil. This may be mis-diagnosed as a rear main.
Take a mirror, and look at the rear intake seal. Any type of leak up top should be fixed prior to doing any leaks underneath.
