While swapping my 5 speed for the celica 6 speed I decided to try and fix the oil leaks. Here is the history.. used engine 2zz on stand. I cleaned everything and replaced all the seals. Engine showed evidence of small leaks. 4 months later the dreaded oil puddle under the half shaft. Then sling all over the clean engine bay. I removed the cover (what a pain) changed seals and retired the packing seal stuff. 6 months later.. leak was worse. Now with the 5 speed out to put in the 6 speed I held the engine by a lift so I can move it for easier access. Now getting ready for the third attempt. Got all factory seals and toyota seal packing stuff... any tips? I do not want to do this again. But I am getting good at taking this thing apart. Oil sludge is everywhere so not 100percent sure where it was leaking. Was getting on the serpentine belt. So maybe leaking everywhere.
