Just picked a a 1990 740 turbo wagon with a blown headgasket. It's a really clean car with 185k and a pile of service records. I've never done a headgasket before so if anyone has any tips i will be thankful. I've found turbobricks.com and swedishbricks.net and there is a ton of great info there so i'm pretty confident i can do this. The timing belt was replaced 5k ago and the water pump was done a few weeks before the headgasket blew. i know people say it's a good idea to replace these at the same time as the headgasket but i was planning on leaving them since they are so new. is there anything specific that will be different in the headgasket job because this is a turbo?

I know a bentley manual for the 740 doesn't exsist but the engine is pretty much identical in a 240 correct? assuming that the engines are pretty much the same i should be able to use this video as a good reference right? http://www.youtube.com/watch?v=SRUPgYbk_gE

here is a pic of the car

Spend the dough to have the head flatness and crack checked. I've been working on Volvos professionally since 1980, and I've only seen maybe 6 actual head gasket failures. The rest of them were either warped over.020" or cracked from extreme overheating.

Headgaskets easy!

Step one- Pull turbo, and plumbing

Step two- Sell to me for $50

Joking aside, Yeah that should be the "Redblock" B230FT... I think. One cam right?

If dual cam, look for info on the "16V" this seems to be how TB people classify this stuff. Good luck!
