i gutted my cat and now i have alot of smoke coming out the exhuast once i get of the throttle. my oil return is above oil level and is the same size as a dsm. turbo only has bout 200 miles on it and i know its not the engine seals or rings so why do i forecast rain once off the throttle. its cool while punching it.

 

If you gut your cat expect your ride to be stinky and a smokemobile.

 

uhm u remove the cat it wont be any more smoky. the cat filters out HCO i believe.

rings, valve seals, turbo seals.

 

check your vacuum,you may have a line loose

 

has anyway else had this experience. the engine seals are fine. doesnt smoke with turbo off. the turbo itself has only bout 200 something miles on it.

 

I replaced my entire exhaust system when I went turbo w/a 2X resonator & a flow through muffler. No smoke until a piston ring went. Why R U certain that you don't have internal engine problems ?

 

because with the turbo off. no smoke

 

do you have a blow off valve?

 

leaky turbo?

 

then it has to be the turbo, or a shitty oil return line, the oil fitting in the pan has to be above the oil level in the pan, or it will backup inside of the center section and cause a leak to blow out your exhaust.

gutting your cat has nothing to do with smoke.
