Hope some one can help with this.
My vette has not been fired in 4 or 5 months. I fired it up today and it was smoking like a freight train. ![]() It was however spewing a little fuel from the carb when I shut it down last fall/winter. I was able to back it out of the garage(befor dieing of c/o poisioning) and smoke was pouring from the side pipes(again, It did not do this when I parked it) It wouldnt clear up so I shut it down. I lifted the hood and could see what looked like dirty fuel (was for sure fuel,but looked just a little oily) all over the top of the fuel pump and a little laying in the intake manifold at the base of the factory holley carb. I also noticed some on top of the right side exhaust manifold, thought maybe the fan blew it up there?? When I could finally enter the garage again, there was a small puddle of the same dirty fuel on the floor just below where the fuel pump would have been and a drip pattern where I had backed out. I also pulled the dipstick and it smelled strong of fuel. Is fuel some how still flowing into the motor after it is shut off? ![]() What do I do?? Thanks everyone!! |

The diaphrahm in the fuel pump might be bad and letting gas drain into the oil pan.

Charley is right.... though sometimes if it doesnt run right (too rich) it will wash the cylinder walls and smoke

Thanks for the quick reply guys!!
So I could have 2 problems, 1 the fuel pump diaphrahm and 2 a rich carb. Why so much fuel all over the top of the fuel pump and on the garage floor? What about the small puddle on the intake just below throttle arm (driver side)? I should change the oil now? or just before I fire it again? Thanks again guys! |

There is a little hole in the side of the fuel pump. When the diaphram goes bad it will weep stuff out of that hole. You could also have stuck float in the carb that could make it flood. A stuck float will let any pressure in the fuel line overflow the carb andf fill the intake, eventually making it's way into the cylinders and past the pistons into the oil. Drain the oil before you try to start the car again. If there is enough gas in the oil pan it can make a heck of a explosion.

Although my guess is that the fuel pump diaphram is bad and/or the float is stuck, I once had a major smoking problem from a stuck choke (black, rich gas smoke), so you might check that also.

It took out the oil pan, timing cover, internal parts of the Holley carb, both valve covers and several gaskets not the least to mention a fire. The A/C oil breather on the cover almost imprinted in my head as it preceded the valve cover by a few milliseconds. Not a pretty sight. Rick
