that haynes manual is garbage. read my sig line.

i have done dozens of timing chains. i would say 90% come off and go on with out struggle. when you go to put it on, you use rtv to hold the gasket to the cover. the head gasket is graphite, so as long as you clean the top of the cover and the gasket it self, it will seal. but for good measure, i always put a dab of rtv on there. the oil pan is designed to hold in the FIPG. it has a recess for it.
the way i do things, the head gasket and the pan never leak.

i cant tell you where YOUR leak is. if i had telepathic skills, i would be a very wealthy man.
