Thread: white exhaust

Tweet

I havent started my engine for about 5 months now, give or take, and today i started it and after about 30 secs of running my whole garage was filled up with whitish smoke. Is this normal and if not what might cause this. The gas is about 5 months old too, but i had fuel stabilizer in it, so i dont know if that had to do with it either.

thanx

White smoke usually indicates some water burning. That would indicate some head gasket problems, to me anyway. Not sure what motor you're running, but you might want to re-torque your head(s). Otherwise I'd say the head gaskets are just worn. Unless this happens every time you start the motor, I wouldnt worry about it too much, just keep an eye out if it starts to get worse or not clear up after a few minutes.

Just my 2 cents anyway, I'm sure others will chime in with their thoughts.

thanx guys. Its a 454. The smell is gassy smelling, but im the one that has had the problem with fuel in the oil pan, so now im finally getting around to just jetting the carb way down to elminate the carb as the problem and then this came up and just wanted to find out what this new thing on my adventure was.
and no, i didnt add much stabilizer at all acually. Maybe get about 5 gallons of new gas?

thanx

well i think im about the stupidest person alive. I just looked at my oil level and there was none in there cuz last time i drained the oil and thought, ill just wait till summer to put oil back in and forgot. Hopefully it doesnt do anything with only about a minute worth of running.

But now, i just put in 5 quarts of oil, just so i wouldnt make the same mistake again. I pulled out the dipstick and the oil was all charcol color, as if the gas is already back in the pan from just a minute of running. WTF is wrong with this thing?
Any help would be appreciated.
Also, i just want to make sure my fuel return line is setup right. I have it hooked up to the regulator and then it goes back all the way to the top of the fuel cell in the back. Is that correct?

thanx

Are you running a mechanical pump? If so it may be leaking internally and dumping gasinto the pan. Electric--pressure could be too high.

no its electric, and theres a block off plate and everything there.

thanx though

im sorry, i try too but its so hard to remember everything cuz im been trying to fix some of this for like 8 months now. The fuel pressure is at 5 psi and the carb is pretty much brand new. they floats are also set correct.

Thanx again,
david

holley. it was a 4150 hp 750 cfm and then found out it was a pure race carb, and then just got a 770 cfm street avenger.

Do you think this is an internal problem and not a carb problem?

thanx again,
david

the vaccum is 5hg in gear and 8 in park. I have ran a 6.5 down to 2.5 power valves and still have the same problem. Its also a 280 gph fuel pump, i dont know if its too big or not but just thought id throw it in.

i forgot to say the cam but its a 292 isky with a 590 exh lift. I cant remember for sure if i did check the float level after the engine was warm but i think so. How would i know if the back and front bowl were changed? I only took it apart 2 times and just did one side at a time so i know i didnt do it but then again, with 2 different carbs, maybe one of them did.
I did replace the base gasket but i have taken the carb on and off like 10 times so i dont know if that matters or not.
A while back i check for some vacuum leaks with some carb cleaner and didnt find anything in the base of the carb or on my vacuum advance line, which now i know the vacuum advance wont even work since i dont have enough vacuum.
I will check the manifold torque but im scared to even start it now since i got gas in there in just 1 minute of running. That just freaks me out. I know i need to check the vacuum around the manifold though.


Thanx again,
david

oh. ok. thanx. I didnt even think to use the vacuum gauge. Ill try that and see. Also, if these were the problems, would it really throw that much fuel in the pan? Before i stopped driving it, i drove about 10 miles and the oil just reeked of fuel, and was thin. Sorry i didnt mention this earlier.

Thanx again for all the info and help. I really appreciate sticking it out with me.

What size jets are you running in the carb. you may have too much carburetor even for that motor.

ive had it down to 71 and 73.

reason I ask is I have a friend with a modified big glock that had the same problem. He had a Holley on there that was puting raw gas into cylinders. He changed to a Barry Grant carb and cured the problem. If you have access to an Edelbrock or BG, you just might want to try it and see what happens.

hmmm. thats weird huh? Wonder how that would do that. Im just frusterated over all of this, i might just take it in to some shop to get it over and done with but i might try the other carb and see. I have tried only holleys.

thanx for the tip.
