Alrighty folks, my days of buying from the Volvo dealer are over. I'd been having real problems with getting my 'K' cam set up right. I got a lot of good responses about what may have been going wrong with it, and it turned out to be supertight valve clearance. Wouldn't you know it, I really screwed up on measuring the clearances to buy the shims, and the shims I bought at the Volvo dealer ($6.80 each) were too loose. I knew I'd been ripped off, and didn't want to deal with Volvo anymore. I received information about a website called www.bimmerparts.com from John Sargent. They're called Zygmut Motors, and they sell parts for all sorts of euro cars. I checked out their product selection, and they have a parts inventory that easily trumps all aftermarket Volvo sites I've seen, and rivals the dealer itself! I bought the shims for $1.40-1.50 each, and a pcv kit to fix my broken one for $2.60! This was a huge difference in price over the volvo dealer! I placed the order at 2pm yesterday (tuesday), requested 2 day air, so I was expecting them thursday night if lucky, and definitely by friday morning, taking into consideration time to process the order and such. I'm working on the school newspaper in the office, my brother calls me, and says they arrived today at 2pm! 24 hours! MAN thats fast! This may either be extreme luck, or I just found a great volvo parts supplier! I highly recommend these people now. Thanks for the tip, John, I owe you a candy bar. Hopefully I'll have these shims in today, and everything will be running smooth and quiet. If I get em done by 6 I'm heading to the track tonight!
