alrite i got a 00 gsr with about 100k on it (change the oil religously) havent sprayed it or boosted it, a while back noticed a little blue gray smoke when i first drive it in the morning mostly but sometimes here and there while driving it also went through some oil a quart every 2 weeks and the pcv kept gettin alot of oil in it, also got a oil leak maybe rear main or tranny havent pin pointed it yet and that dam black box, took it to a shop had them test the head (supposdly) but he juss half assd it an tested it for coolant leakage didnt test the valves he put a new oem(honda) head gasket and i had em put some 00 typeR cams in it with a valve adjustment, ran alot better probly the cams obviously) but still smoked about the same maybe a lil worse. i did a compression test and it was off between highest 185 to 145 was the lowest cant remember exact. what yall thinks goin on bad valve seals/stems or guides? got the head off taken it to get rebuilt tryin to figure out if i should mess with the bottom end or not, daym another thing i use to have a apexi cat back and put a stock exhaust on thas when i started noticing it, thanks for reading my book
