hey guys, i have a '00 civic si with the b16a2. i havent had it for too long and its been burnin oil a lot. I put it up on the lift and checked all around and there wasnt any oil leaks. I drive at bout 80-85 on normal freeway and the rpms are at about 4500rpms. when does vtec engage on the b16a2 motor? Would drivin 80+mph at 4500rpms be the cause of me burnin oil?
