Default JDM B18C1 with white smoke at VTEC

Hi All
So with my recent C1 swap into my EK, I'm noticing white/greyish smoke out the exhaust when I hit VTEC...any ideas why? And is this normal?

Doesn't smoke at all out of vtec?

I would do a leak down test, that would tell you if it's the head gasket or not

Car is not tuned. ECU was chipped:launch control, redline at 8500,better MAP
Compression was perfect, 230 across
No loss of fluids that I can see
And new plugs were installed.

Possible idea: at VTEC the car runs richer, cause for smoke?

not white smoke.

White smoke = coolant
Blue smoke = oil
black smoke = rich


Possibly blue smoke? How much smoke? Harder to tell what color if smoking only little

is there any oil at the bottom of your overflow tank?
Sounds like headgasket
any over heating?

You can do a leak down to see if any air bubbles are coming out of radiator

Its Blowing Out White Smoke! Sometimes a lot of smoke and sometimes it doesn't even smoke, but i noticed something leaking, its two hoses that go under the intake manifold, its leaking green liquid which i think is coolant because it smells just like it. and no over heating what so ever

Yup thats coolant. Check coolant level. Low coolant can result in a warped head and a blown hg .

But sounds like hg, u should get the head resuranced because it probably warped
