Smoke Comes Out When I Rev

[strickensix]

I've noticed that when I rev, usually above 3k RPM - redline, smoke comes out of exhaust. The car isnt burning oil and has been running perfectly fine. Any idea on what it is? Mods are in the sig. Headgaskets were replaced with aftermarket gaskets before I bought the car when the engine was torn down.

What color smoke?

Whitish and light bluish. Ive found an old thread about Mustangs smoking on start up, but nothing about revving.

This is the thread im reading up on but I havent noticed any smoke on startup. http://www.svtperformance.com/forums/showthread.php?t=38033&page=3&highlight=smoke+rev

Smokes while you reving or on the way down from the rev?

Smokes while you reving or on the way down from the rev?

On the way up only. It smells strongly of gasoline. Oil level doesnt really change, I've only had to fill it up with half a quart maybe once after about 2000 miles after an oil change.

I dont know if the car is tuned or not either with this setup, it was tuned when it had its supercharger on. The car has an ungraded fuel pump and injectors as well, I have to call the previous owner to find out exactly what they are.

sounds like unburnt gas to me...which is usually cause by an O/R pipe

If your on a blower tune and bigger pump and injectors but without the blower then my guess is it's rich as hell.

You have an Offr road pipe..its expected

 

[ubnsmkd03]

does that cause smoke at start up too

Strong gas amell is expected from a O/R pipe but not smoke.

That's looks like fuel.

ya it's not because of the O/R pipe, but I've noticed the exhaust fumes are strong when the cats are off too, only smell it when the windows are down at a standstill and it's more noticeable than some other GT's that my friend's have with no cats, anyway to get rid of this? tune maybe?

Would swapping down to smaller injectors help remedy this? I think the owner told me that they are either 24lbs/hr injectors opened up to 42lbs/hr or they are actually 42lbs/hr injector. And the fuel pump may be a Focus fuel pump. All because it was supercharged.

Alright, after making that video early, I had to add about half of quart of oil (low oil light came one, checked dipstick) so obviously, its burning oil. What can remedy this?
