Blue Smoke from exhaust PLEASE READ!

I've had gas in my oil becasue of ground injectors(Edelbrock intake problem)
when the car was finally started after a month or 2 with gas being dumped into the oil, a lot of blue smoke came outof the exhaust.. why?? should i be worried about valve seals, or is it just from the car sitting for months??
ps,,when the gas was in the oil,, the car was never run for more than 5 minutes, so i dont think any damage was done.

Mine used to blow that puff when it was first started after it set for awhile until I changed the valve stem oil seals. If that's the only time you're blowing smoke, I wouldn't worry about it too much. If it's blowing it while you drive then the gas in the oil may have damaged the engine.

If the gasket doesn't seal properly then yes, it could be sucking up oil from the intake valley, carry it into the combustion chambers where it gets burned up causing it to smoke.

I agree w/Blade. I had an Action + on the 396 that wasn't machined right and sucked oil out of the valley. Used a lot of oil and put out a lot of blue smoke. Who told you it was the wrong gasket, and why?

The other possibility is that the gas-diluted oil is/was getting past the rings. You didn't say that you changed the oil - does it still smoke after that, or only when diluted?

the oil is new and it is smoking blue..
maybe the gas ****ed up the rings
but it was never driven with the gas in the oil! only started, no more than 5 minutes of running.

i was told by a fellow thirdgenner that the blue felpro gaskets are not for aluminum to cast iron applications,, thats why im thinking it might be wrong..
i also pulled the intake up once and when i put it back i reused the same gasket.. could that have messed it up?

What exactly do you mean? If the intake was torqued down then removed then torqued down again using the same gasket then I suspect that the gasket was eighter damaged when the intake was removed or is not sealing properly due to its initial seating during the first installation. Blade is probably right. Try a new gasket and get it right the first time so you won't have to suspect the gasket anymore. I like/use the ROL graphite coated set when I need to join two different metals. The coating allows the metals to expand and contract without stressing the gasket and causing a leak.
Good Luck!!

ROL gaskets, what does that mean??
Myslowirocz,, what i mean when i say i reused the same gasket is,, i torqued it down once , then reused it,, could the gasket have gotten smaller after i torqued it down the first time , so when i reused it , it was thinner, therefore able to leak??

I would buy another new Fel-pro gasket and make sure you get the right one for your application. I used to work as an engineer in a chemical company and Fel-pro was all we used on our pumps, compressors, pipe flanges, etc. It's all I use on my vehicles as well. They are good quality stuff, just make sure it's the right one. I'm not sure what they mean by ROL? The gasket you have might be leaking, but if the car only blows oil on cold startup I still suspect the valve stem oil seals.

I don't know about intake manifold gaskets, but I know the blue ones (silicone, or something other than cork) are supposed to be re-usable, no prob. I haven't tried it, but I changed my valve cover gaskets over to them, and beat them up a few times trying to get the valve covers back on w/o removing a lot of other stuff in the compartment. Not a leak since!

I went ot my local parts store and they tried to give me those (ROL) and after looking at them for a few seconds I gave them back. My FelPros were on my car for 4 years and they looked like new when I removed them 2 weeks ago and was tempted to re-use them they looked so good but for $13 I got a new set and played it safe.
