today I did a boost leak check and found some leaks near my throttle body and where I tapped my meth nozzles. After the check I started my car and noticed I was smoking badly during idle. didnt think nothing of it until when I left the hobby shop and I was still smoking all the way home.

After I got home I decided to take the car out and see how it does on boost and if it was still smoking. It didnt start back smoking uintil after I got on it and sure enough a loud POP and huge clud of smoke came out the exhaust and it continued to smoke like before. I also noticed I overboosted at one point also which my car hasnt done in years.

NOTE: There is alot of hesitationb when I get on it.

Any ideas? I need help

What color smoke?

 

How did you perform your boost leak test? My guess would be oil from pressurizing the system... It will burn off, don't sweat it too much.

 

it is a whie smoke and it smells pretty bad. It was weird to because im overboosting now and all i did was a boost leak test

 

Did you fix a leak? You could be over-boosting because you fixed the boost leaks so lower your boost.

 

Did you remove your oil cap when testing?
And if you did, did you put it back on? And if you didnt you likely pressurized your oil/pcv system

 

No I did not remove the oil cap but I did remove the UICP to see if I could get a feel for the throttle body leak. so how do i fix the pressurize system.

 

just got back from a ride and its boosting fine and not hesitating, its hard to tell if im smoking when i get on it but after im off throttle it is still smoking

 

sounds like a head gasket... without having the car in front of me i cant tell you for sure.

what are some other indications of a blown headgasket

 

You can check your oil is the most obvious for a blown headgasket. If it looks like a milkshake, a chocolate one, then there is likely coolant in your oil. Another way is to pull spark plugs and if you can get your hands on a bore scope, look in to each cylinder. You are looking for coolant on top of the piston. You will also be able to tell when you pull the plugs and one or all plugs are wet with coolant. Hope you get this fixed...best of luck.

 

check your coolant for oil or vise versa. If your oil is milky, blown gasket

 

thanks going to double check oil and pull plugs BRB

 

also your coolant reservoir will be topped off if not completely bubbling over.

you can let the car cool down all the way, and try to bleed the system if once the thermostat opens the fluid level just rises beyond control its pressure going into the coolant system from the combustion chamber....

how ever if the head gasket didn't get pushed in this way and only an oil galley was breached then you'll see white smoke that smells like burning oil its distinct.

the coolant will be the obviously sweet smell and will tend to hurt your eyes more as if the car was running really rich.
