Hi Guy's, I am in the middle of replacing my head gaskets on my '99 D2 V8. I have had the heads skimmed and the the combustion chambers tested for sealing - all ok. As part of the VRS kit there are new valve stem seals that i feel I should replace considering how hot the thing got when the head gaskets went. Have pulled out the first valve, but cannot seem to shft the old stem seal to replace it...Any tricks or pieces of advice on how to get these buggers off. Also the new stem seal appears to have an inner black rubber seal boot inside it....how hard is it to get this to slip over the end of the valve without rolling it???? Any help would be great... Cheers in advance.
