My 05 s40 T5 blew a head gasket and I took a couple months rebuilding it thanks to the resources on this forum. It was a PITA but I'm better for having done it. Now to the real question, I have the opportunity to buy a 2004.5 s40 2.4i on the cheap that popped a timing belt. He took it to volvo and they just quoted him for a new motor and he said nope and let it sit. Now armed with my new found skillset and tools im feeling froggy. It would make a great car for one of the kiddos. I know what I'm be getting into from the head up and expect a valve job, but what are the odds of cylinder and/or block damage?
