wat could it be ?? i blow alot of white smokes when i hit vtec... anyone ?

 

blown head gasket

 

sounds like somehow there is coolant getting into the combustion chamber - most likely a blown head gasket as described above or a cracked block (probably not).

 

headgasket's new...just got it rebuild 2months ago...coolant's still on max level...it only happen when i hit vtec... it doesnt smoke on idle or on start only when vtec...

its a different story if u blow ur gasket...coz it happen to me b4...thanx...

 

You may not have blown your headgasket, it could just be a small hole that lets coolant seep in under the higher pressure of VTEC. Are you running forced induction?

 

possibly the top of the block may be warped, allowing a little coolant to get burnt. Still its wierd it only happens at vtec..so idk, good luck

 

Is the block sleeved? It could be the bottom of the sleeves are not fully seated. This happens from time to time.

so i think im burning oil...i checked my oil level and its a lil lesser...

could it be piston ring ?

 

this is basically how colors for smoke goes

white-lean
blue burning oil
black-running rich

thanks my bad.

 

sounds normal,my 92 GSR with 210k miles lets it be known when shes in vtec

 

could be a small leak thats being blown "clean" under load.

Im just grasping at straws, here.

 

what was the cylinder wall clearance, what breakin cycle did you run it through, what oil was in it during breakin, what weight is in it now. were the valve seals replaced

?

check your pcv valve. do you have a cold air intake or a clamp on filter on your valvecover breather?
