ok so ive had problems with this for quite some time and thought it was a head gasket but multiple tests proved wrong.
originally i was loosing much coolant and vtec would randomly cutout everyonce and a while.

-i found 2 large leaks once the car was in the air and fixed them(one in a random connector made from the swap and one at the heater core).
-next i did a compression test on each cyl. and it passed with flying colors.
-from there i did a vaccum test and also passed that with great outcomes..

soo..
does anyone have any idea what could make vtec not work at times or feel weaker?

hows your oil pressure and oil levels cause if there low that could be the problem

idk how id check my oil pressure but everything seems in check.
got a little leak from that sensor in the back by oil filter.
she does need an oil change but i dont think that would effect things so much
would the weight of oil effect at al?
as of now theres 40wt in it.

Fix your oil leaks.
Run 10w30, 40 is kind of thick (but not horrible). Thick oil will cheat you into a higher pressure, but isn't necessary on a well/properly built motor.

Engine codes?
Is the screen in your vtec solenoid clean?
Have you tried replacing the vtec solenoid?
Are the wires making good connection at the vtec solenoid?

ok sweet.
also with this new header the down tube is really close to my oil pan will that heat my oil to the point i should run thicker??
the engines only got 40k so w30 will be fine.

no cel's.
ive checked the screen once but ill look again.
and ill look into the solenoid and wires.
thanks!
