I have B18c1 swapped in my civic. I/H/E. with a chipped P28 but it has a stock GSR map with little things modded such as a stutter ox raised rev limiter. since i got the car i have burning coolant and oil not too fast but consistantly. I always thought is was from hitting VTEC, but recently i was on the freeway and i was in third gear at about 4k the i hit the gas WOT and i notived i had lit the whole fourlane freeway up in a whiteish gray smoke.

So far:
-Pulled plugs, no residue just a lite white/gray covering the plug
-compression checked out ~200 across

my car runs perfectly any other time just when i punch it. it smokes up like that
is it just the fuel dump from the ecu and VTEC engaging? or maybe an early catch on a bad headgasket?

any input would help

 

A head gasket will not gradually blow. It is an all or nothing thing. If you did a compression check and all cylinders are in range then it is not the head gasket. My guess is that it is one of the following:

1. Piston Rings
2. Valve guide seals
3. Crack in the head.
4. Possibly head lift ( too much cylinder pressure at upper RPM's bypassing holding strength of the head bolt/studs.

 

do a leak down test then you'll know for sure.

 

x2 thats the only way to be positive, unless u rip the motor apart...
