1979 L82 exhaust oil

[Ron S.]

I have oil coming out of the drivers side exhaust. The compression is ok and the plugs are clean. The original 350 engine was rebuilt in 2006 and the car has been lightly driven since 2500 miles. Any suggestions what is causing this?
Thanks Ron

Silly question.... you're sure it's oil?

It's not unusual for "black water" to come out of the exhaust of little used cars. It drives my friend's wife nuts because his Austin-Healey spits it on the floor of the garage and makes it dirty. I've seen other cars do the same thing, though.

It'd take a heck of a lot of force to push oil all the way through the cat converter and exhaust system and then come out the end...

If you've actually got oil coming out the exhaust, the car would be smoking like a WWII destroyer setting down a smoke screen and your oil consumption would be so high you'd be adding oil every time you drove the car.

My thoughts exactly ! Double check to be sure it's not just moisture. If it is indeed oil, we might have to dig deeper.

I get some of this with my 70 when I first start it. Doesn't drive me nuts though.

Re: 1979 L82 exhaust oil

Guys, one other thing my friend says the exhaust stinks when you follow me. Once before it stunk real bad, ate up the oil and smoked real bad out both sides and that was a pcv valve problem. This time not real noticible smoke and not a lot of oil being used. just black and wet on the one side exhaust tip and sticks. Any more thoughts Thanks Ron

Re: 1979 L82 exhaust oil

I'd say she's running rich and you have moisture in the exhaust. The result is the black sooty moisture you see coming from the muffler. Of course I haven't seen your car, but from the info we have so far, I'd say that's the case.

Have you done any recent work to the car that may have caused this condition you are noticing ??

Have you had the car long. Has it always done this or did it just begin ??

Re: 1979 L82 exhaust oil

Ron, I think Tom has you on the right track, soundslike a fuel related problem, just to add some advice, take a look at the Automatic choke sometimes when there not operating properly they will cause the engine to run rich, and give you that smell out the tail pipes,

The electric choke is run on 12 volts, and has a wire on it that tends to lose its connection from a rusted terminal. The choke butterfly should be wide open after a few minutes of running.the warmer the engine the shorter time it stays open. and the colder it is the longer.

If all checks out with the choke, check to see if the charcoal canister is drawing un metered fuel into the carburator viva through the vaccum hose at the base of carburator.

Re: 1979 L82 exhaust oil

Thanks guys I think were on the right track, I recently put duel carbs on it. The engine has a moderate cam and headers. I will look at the fuel issue tommorrow. Ron

$10 says it's running way too rich.

What carb, cam and headers? Did you change anything else?

Elgin "pro stage3" camshaft? do you have a part number?

Edelbrock carbs, I assume?

What brand and model of pistons?

Auto trans or 4 speed?

Re: 1979 L82 exhaust oil

Two 500 cfm carbs on a 350? I think I see a problem right there.

A problem for drivability............. or judging !!! ??
