Sounds like a timing adjustment was what the doctor ordered. Very typical with these engines to find it has been driving around for years with improperly timed IP, because, as you have seen, the timing procedure is pretty logical once you have a feel for it.... BUT, many professional mechanics do not take the time to comprehend what is going on and thus it is common for timing to be set incorrectly after a cambelt change. This was a frequent occurrence even from Volvo dealers doing work on them back when the cars were new, and unfortunately sabotaged many otherwise good engines. But it's corrected easily enough and they sure do run differently when everything is dialed in as it should be. As for the turbo -- certainly a refresh is never a bad thing, but, turbochargers are something we find virtually never need attention on this engine. As a rule they pretty much just don't fail except if some external material damages them. So unless you see evidence yours has some kind of issue, or you just want to do it for fun, it may save you a little time and money to skip any efforts on that particular area. Quote:
They made the pump adjustable too because.... it's German! Why only give us one way to do it, when they could create confusion by offering two paths to the same destination? In all honesty though, as you pointed out, each method has its own upsides/downsides so it is sometimes convenient to be able to choose one or the other. Sounds like a very nice car that is coming together well, kudos on the updates. We never saw the diesel model Volvos past 1986 here in the US so are always envious to hear about the improved 1990s era diesels on your side of the pond.
