Do I have to pull the motor in my 1981 Porsche Targa SC911 to replace the front main seal?

Answer 1

My understanding is that you will need to split the crankcase in order to release the main seal (and that will requrie you to drop the engine). I haven't done this myself, but with related O ring leaks and such from people I know, they always choose to address this when they are doing rebuilds or other major engine work.
