ITRCA

My car is burning oil like crazy. The thing is that during normal driving (low RPM's), there is no smoke coming out whatsoever but when it hits VTEC I can see a cloud of black/grey smoke. Is that a sign of bad oil rings or could it be anything else? I know it could be running too rich but it wouldn't burn oil in that case. Any help would be great. Thanks

i had ring problems on my R and it blew out black smoke. im not sure why ur car would only smoke when vtec is engaged, but it may be a ring...

black smoke= rich/ fuel.
blue smoke= oil
white vapor/ cloud= antifreeze/ water
grey smoke= I have no clue.
red smoke= Vtack powaar

Try a leak down test and a compression test. or is could be the type of ECU you are running.
