drove it 250 miles round trip to an autocross did 8 runs and returned home and it burned a little over 1 quart of Oil. I can drive around and go down hill with huge vacuum then accelerate without going into boost and don't see blue smoke in the rear view. Seems like high vacuum would suck in oil if it was valve guides. It also doesn't smoke noticeably when I first start it up or just let it idle. It smokes quite a bit of blue smoke when I go into boost whether boost was proceeded by vacuum or not. PCV removed and replaced with a hose to the catch can doesn't change anything. no blowby in the breather catch can ether. No oil leaks around the engine, oil is going out the tailpipe. Cylinder #1 shows a fair amount of oil contamination on the plug and the top of the piston and none of the others do. I don't measure bad compression or leakdown in any of the cylinders and it doesn't feel noticeably down on power, dynoed at 338 hp with good and slightly conservative afr. I replaced valve stem seals on the intake for cylinder #1 without removing head. valves seemed reasonably tight in the guides when I wiggled and spun the valves by hand. I saw no glaring issues. no change in tailpipe smoke though. Bob Did you have occasion to replace the oil pump or modify it for greater pressure? **************Get fantasy football with free live scoring. Sign up for FanHouse Fantasy Football today.
