I've got a '90 745 with what looks (to me) like a bad head gasket that's spewing fluid all over the place. Enigne is strong and turns over. No smoke. Clean emissions.
Someone suggested to me that it might be the flametrap that is causing the problem.
I picked up a new flame trap from IPD. My questions are...

1) Where does this thing go?/Where is the flame trap?
2) Will changing the flametrap fix the gasket leak?
3) I'm prepared to change the headgasket if needed, how much work is involved?
3a) Do I need to have the head machined? (See question 3)
4) Is this covered in the UK Haynes manual?
5) is there anything else I'm missing?


I'm looking to sell it at this point, since my wife is getting tired of the used volvo lot in our driveway.

Thanks in advance.
