Tam, please don't be offended, but it seems to me you got a reasonably complete answer to your question. It didn't seem to me that that the other question did anything to detract or take the emphasis off of yours (?). While you are certainly correct about the definition of hijacking a thread (actually it's the best definition I've ever seen), I think before jumping on someone you might consider the spirit in which they interjected - and I don't think the other question was intended to cause any problems. Just my $.02, I'm just happy to be here.
A full set of Volvo FSM's will cost in the neighborhood of $80-100, but I would refer you back to my earlier comments before spending that kind of moo-la.
Mk, according to my Seloc manual that covers '92-'03, the compression variance allowed is as follows: the lowest compression cylinder should be at least 75% of the highest compression cylinder. My VP manual, which applies to specific variants of the 5.0L and 5.7L, says the same thing; it also specifies a compression ratio for both blocks of 9.4:1. However, *neither* of them explicitly state an acceptable range of actual compression values. The closest thing to it is in the VP manual, which contains a table of values that is only intended to keep you from having to do the math to figure out what 75% of the highest cylinder is. If it's of any value, this table shows max PSI's ranging from 134 to 212. Whether you can infer that your highest compression cylinder should fall into that range is not clear.
I went to the trouble of looking all this up and laying it out as clearly as possible, for two reasons: 1) to help Mk if possible, and 2) because (getting back to Tam's original question) this exercise makes a nice example of the difference between the FSM's and Seloc, and how both of them together still don't answer all of even the most basic questions.
