my car has been really smoky, and ive given up on the idea that its a fuel problem, by the way the smoke is white and im pretty sure its running rich because of lack of air since i thought the air filter was clogged so when i took it off it didnt suck very hard also it slowly loses the fuel pressure when i turn the car off and i was wondering if theres something that would cause both problems also my car leaks oil if that has anything to do with it

by any chance would it likely be the eacv (electronic air control valve) or cvc (constant vacuum control) valve the reason i ask is because if a sensor doenst work it doesnt block most of the air or anything does it

also but importantly when i start the car it doesnt smoke but then it starts gradually getting worse and if i rev the engine it smokes a lot too

 

Probably a blown headgasket causing coolant to leak into the cylinders.

 

your probably right i put a new gasket on when i took off the head to replace bent valves but i might up ripped it a tad but anyways now that i think of it i had to take the radiator out to bend the supports so my hood would latch and just put water in now your going to think im a dumass but just so you know my car has had so many problems so i started to not care also its my first car

 

Leaking Injector would cause both issues. When you shut it off it leaks the fuel into the cylinder, and when running it's injecting too much fuel causing it to run to rich.
