hi, i was wondering how difficult it is to replace a leaky oilpan, or just redo the seals on my 1988 GX. i have little to none experience with working on cars, but im not inept... i could prob figure it out... i was looking thru the haynes manual and it says i have to hoist the engine a bit to get at it... can anyone who has changed theirs tell me the process for it, and if its a simple few hour job? thanks!!
