the problem is that there is very little room to work and its an interference engine which means if you make a mistake the valves and pistons will meet wrecking your engine. for this reason alone i would pay volvo to do it if i were you.
thanks for the reply guys!!! i might go see one tomorrow from the big blue car company in essex. the insurance is cheaper than what im paying on my nissan 1.8 na!! thanks again!!
