well just put a 96 low compression b20b in my brothers crx. runs great,compression is 185ish on all cylinders[which i think is good for a low compression b20]. its using some oil though. also its not the valve seals,no smoke on decel. only see a little oil smoke sometimes when we run it hard,but not everytime.plugs are burning pretty clean[stock ecu] could crankcase pressure be a culprit even with the 7,000 redline. b20's dont vent from the block,just the nipple on the valve cover.has anyone else experienced this with a stock redline? im gonna get 2 of the prelude block fittings and vent the block in the near future,and also step up to a 0 or 10w40 oil,right now it has 5w20.i was just curious if anyone has had this problem or any experts have some advice. if i cant fix it ill assume the oil control rings are gummed up and not scraping the oil well. if so ill change them out with new b16 rod bearings to block off the oiling holes in the rods to limit the oil on the cylinder walls to reduce burning in the future.thanks in advance
