well i took it out again to see if the problem was still there....idle sounds like an exhaust leak near the header........car runs fine and idles fine but when i accelerated and hit 4000 rpm it boged and i lost all power and then big cloud of white smoke came out my tail pipe once i let off the gas it went back to being fine....now i havent sprayed since thursday and it only started boggin yesterday.....could this be a head gasket or a piston problem??

only things ive done lately was install a fuel pressure guage and a high flow cat....and no the engine light never came on
thanks

 

I wonder if you burnt your head gasket or piston rings. Nitrous gets pretty hot for stock gaskets. Try to smell the smoke(don't try to get high off of it) check if it smells like you are burning oil. That might be something to check...although it might not be an easy fix.

 

white smoke and bogs souns like coolant leaking into combustion chamber .do a compression test or just go straight to the leak down

 

should mention that car runs fine except at WOT......and it is only like 10 degrees today so all smoke is white....doesnt smell like anything burnt.......and i havent sprayed since last thursday........so i would imagine something like that would happen while spraying and not daily driving.......

 

What does your oil level look like? Is it overfilled?

 

i just rolled 5000k so its about 3/4 and still gold.....which is normal

if i turn it on cold and take off the rad cap it and it bubbles its the head gasket ??

 

Is there a milky white substance on the bottom of your oil cap?

 

nope why???

 

Probably.

 

i didnt do it cause its dark out but i will tommorow morning.....just tryin to save on diagnostic time.....put him in the right direction.....

 

Often a result of coolant mixing with the engine oil

 

problem is....

after 3 days of heavy downpour and driving my aem cai seems to have sucked in quite a bit of water.....compression is between 185 and 195 all across and the oil change seems to have cured it

thanks for the help boys glad it was only a small problem
