Well after 2 years of waiting i got my firebird going and it was driving very nice for the first 15 miles. Then havoc struck. I was on the freeway doing about 45 and i began to smell coolant pulled over and saw a little bit so i just assumed a leaky hsoe so i was takeing it back to my friends shop then all of the sudden i got a big ol cloud of white smoke from under the hood and behind me enough that it messed up traffic and made a wall of white. So i called a tow truck and had it towed back to my friends shop all of 5 miles. While i was waiting for the tow truck i noticed that the smoke was comming out of the passanger side muffler. So when it got to my frineds shop he turned it on and it made a hudge clould of smoke out of both mufflers this time. I though it was the head gasket but he said the smoke smelt like oil. What could this be it is a fresh rebuild and when i pulled over i noticed coolant not oil on the ground. Im thinking headgasket. But he thinks it might be something internal or that the gas mixed with the oil and thinned it down. Im really pissed because i bought the motor 2 years ago it was a freshrebuild and spent over 2 grand to buy it for this to hapen please say its something simple.

ITs a 455 with a torker 2 intake deamon carb 750 and a hollwy red fuelpump.

I did notice that wheni stoped the fuelpump was running i realised the car let me take the key out while it was in the ACC mode. Could it just be a ton of gas? Also the gas is about 2 years old but i put that red stuff that is susposto stop it from going bad.

 

Sorry dude...sounds bad.
You can do a coolant system pressure check and find out pretty quick.
You an rent one or buy it for about $100.
Had that happen with a caprice once a long time ago, but that engine was very old and needed to die.

 

8,000 dollars later i hate that damn car i need good news. The car ran awsome up until that happend. But i saw coolanr comeup from the pasanger side of the engine i had no hood on. And when i shut it off i was in my g/f's car waiting for a tow and saw just the passanger side exhaust smoking and there seemed to be coolant on the ground. I checked the oil and there was still oil on the dipstick.

 

The cooling system pressure test is a good idea and I would also recomend a compression test and possibly cylinder leakdown test if you have a cylinder thats low. If that checks out OK then try a fuel pressure test.

 

Could too much fuel pressure cause that i have a holley red going into a 750 cfm deamon carb. It just blows when u spend all that on an engine only to find out its broken

 

do you have a fuel pressure regulator?

 

No from what i was told a holly red shoul d be putting out 7psi and would not need to be used.

 

Something tells me you don't need to bother with fuel pressure right now.

Head gaskets don't just up and burst and spew coolant everywhere while driving down the road, as a rule. Mostly they leak slowly and constantly. I highly doubt you need to bother with that right now either.

Most likely, you burst a hose. No big deal. Looks messy, is easy and cheap to fix. Get that taken care of, and see what's left. Frankly I doubt it's any more than a minor $15 annoyance in rubber and anit-freeze, and a lesson to pay more attention to your hoses when installing new motors in the future.

Don't pretend to think you can do without anti-freeze to "save money".

 

All the hoses are brandnew but today will reveal what is wrong i hope. I know the heater core was bypassed because of it leaking. But if it were to be a coolant hose why would wht smoke be coming out of my muffler? And when you Rev it more white smoke would come out the exhaust.

 

were the heads checked by a machine shop for cracks? it sounds like maybe there is a small crack and as it warmed up and built pressure it started leaking coolant into the cylinders. I hope I am wrong for your sake, but I have had the same thing happen to me and I am having to replace my engine cause it gauled the cylinder walls and pretty much ruined the engine. It is good that you turned it off and called a tow truck, if it is a head maybe it didn't have time to hurt it.

 

I hope it has to do with the heads as long as it dosent have to do with the pistons and rings ill be happy. I got the engine compleatly built and the guy said he was going to put it back in his grand prix but put a 350 in it insted. I dont know if the heads were ever check for cracks. I guess if it is the heads i can buy the edlebrock heads but i dont wana pump more money into this car im at the point were i wana sell it and get at least some of my money back.

 

yea cars are a never ending money pit, lol. I made the same mistake and bought an engine that someone else built and I did not get any garantee with it or anything. Needless to say it turned out not to be what he said it was and 2000 dollars later I am finally about ready to drop it in. Any future engines will either be built by me and my local machine shop or bought from a reputable shop that gives garantees. I have learned that most of the time some one sells an engine that sounds to good to be true, it usually is!!!

 

I agree verymuch so

 

I just spoke to my mechanic and he said it seemed internal. But didnt say what. He also said the CARB may have put to much fuel in the eninge. I have this butterfly/sick feeling now.

 

yea if the air/fuel mixture was set extremely to rich, like if there was to much fuel pressure, it could be putting fuel in the oil and wash out the cylinders. That could also gauld the cylinder walls. I hope it is something little nad not something major. sorry man

 

Just called him i guess i will find out tommorw. But damn i miss the first 15 mins setting off car alarms and i barely tapped the gas and it spun the damn tires the engine has insaine horsepower. i hope it is something simple and it can be fixed so i can brake it in and dyno it. I was gonna go on the bottle but i dont think this car can use any more power its almost uncontrolable.
