Do I have to pull the engine to replace this? I replaced the rear main oil seal and still have a leak. So I am thinking this may be leaking.

Willys Jeep Parts Tech:
Its tight back there for sure but you may be able to get it without pulling.

Dear Sir.(s) I've looked everywhere for the way to replace the camshaft plug on a 4-134 engine without removing the camshaft, is it possible, i don't think i should drill it, should i weld a screw and pull ? I would like your advice. Looking forward to hearing from you soon Regards Vitor Caetano (Portugal)

Willys Jeep Parts Tech:
Sorry, i do believe if you want to remove it its easiest to pull it that way you dont have to destroy it to remove.
