ok befor I got this car the guy befor had took out the pcv and took the two hose coming from that box on the back of the block and ran them to a gator aid bottle .then he had the hose that ran from the intake pluged it. at the valve cover was a hose with a plug in it .I put a filter on it but now the thing blows like a quart of oil into the bottle every 25 laps.one more thang when we changed oil put 4 quarts in and was a quart low .found out the dipstick is shorter than my 93 integra by the way this is a 90 integra. would think it needs a rebuild but with all the jacking around with the crankcase presure system .could it be something with that .
