[V6-12v] B4 head gasket replacement

[Tom Christiansen]

Folks,

The left side head gasket on my 1994 90S is leaking about 1/3 of the way
forward from the rear end of the engine. At least I assume it's the head
gasket. Oil is dripping onto the heat shield above the exhaust.

Is there a way to tell for sure if it's the head gasket?

Is there a cheap ghetto fix that would make it stop leaking for another year
or two?

What am I in for if I decide to attack the head gasket replacement? Broken
studs? Heads that will need to be planed? I'm pretty mechanically inclined,
have half a clue, and have the tools (except for tools to extract broken
studs), but I've never attempted anything this involved. How much time
should I expect it to take to complete the job on my own?

Thanks,

Tom
