My friend bought a 83 Volvo 240 DL wagon last year and hasn't been able to drive it much. He tells me it runs great until the engine gets warm or hot.It dies, He was told it might be the valve intake system. If so how do you go about fixing that? What kind of money is he looking at? Is it a easy fix? Or what else could cause this sort of thing? Thanks! I appreciate any help we can get:) It's a 4 spd with overdrive if that makes any difference.

Is this the car on craigslist.com?
