kennith said:Crap parts are relative. Nothing Yugo about it, but they are very old fashioned motors with newfangled electronics tacked on to make them road worthy. The same basic design has been in production since around 1959. Give it a break, already, it's old. That same basic design has had the same basic flaws the entire time, too.
Get it a few degrees out of it's comfort zone, and pop. Let the coolant get too old, pop. Don't rev it like you should, pop. The problem can be attributed to many things, but overall, the motor is very tolerant. It will keep it's temperature very nicely, but if it does climb, you are going to be shelling out some cash. They will also leak eventually with age. Most all aluminum motors suffer similar headaches on various scales. Head gaskets are simply part of the experience.

We had similar issues with Toyota 1Jz engines, as well as a few other all aluminum engines. We were able to cure most of this with the purchase of better quality head gaskets, and a good set of ARB studs to replace the stock head bolts. we also used a slightly higher bolt torque(partly for the studs, partly for the preservation of the gasket during heat cycling). Could this be a possilbe fix on the Rover as well? Or do we not have anything like that. I haven't really looked into the performance companies for parts for these trucks yet.
