HI all
i got the head off my 602 and i am going to take it to a machine shop to get it pressure tested, so my questions are, what do i ask/tell them to do? one of my glow plugs has the end missing, as part of a pressure test do you think they would pull out the pre chamber to get that out for my? how much does this usually cost? any ideas on were/were not to take it to here in the st louis area

cheers

Kenny
