i have a 99 civic si with a gsr bottom end, b16 top end, and type r cams. im makin decent hp and torque considerin my low compression from the b16 head.
problem is, it burns oil like a **** while in vtec. if im drivin it pretty hard it will go through like a quart in 100 miles, but if i drive like a normal person and never hit vtec, it doesnt burn any.
first thought was rings.....but i checked the compression and it hadnt changed. and rings would smoke all the time, not just in vtec, correct?
im thinkin it must be the valve seals....any other opinions as to what it could be?
has anyone had the same problem?

i think it could be valve seals, the oil pressure rises drastically when vtec engages quite posibly could be the problem..

im hoping that it is the valve seals and not the oil rings....

my friend had the same problem with his 97 d16y8 converted civic dx... he uses about a qt every few hundred miles... but itll use much much more when hes in vtec, and swapping heads only helped soo much so its definintly rings.

Rings would normally be constant, but compression check and dirty spark plugs would be the sign for that.

Does the car smoke on startup after sitting a day or two?
