Well, the turbo finally up and went. I've been expecting it for a while, the bearings were squealing pretty bad. All of a sudden it started running like crap, huge, monstrous clouds of smoke poured out of the exhaust, and no boost. Damn, I hate this smurfing car. Something is always breaking or broken on it. I think I'll go shoot myself in the head and put myself out of my misery.
On the other hand, it sure is fun when it IS running right, rare as that is.

Blown Turbo

Do you know which side of the turbo is leaking? Exhaust or compressor. If it is the compressor you had better be careful still driving it because it is likely that oil is gathering in your intercooler and this could ignite destroying your intercooler and a lot of oil will also be passing into the engine causing other damage.

I'm sorry once again to hear that you are having problems. I remember how much hell you had getting your rebuilt motor to run right.

Have you done a lot of modifications? If so, one or some of these mods may have destroyed the turbo--just something to think about.

Also, didn't you buy the turbo used--at a junk yard? It may have been on its way out when you bought it--it probably was. Anyway, think of what you would have if you take it up to Majestic Turbos in Waco, and have them rebuild it. I think it is about $350.

Good luck man.....

Oil will not ignite in your intercooler. Our cars be factory dump a tone of oil in our intercoolers and they don't ignite. Also try putting a lighter or match to some 10w-30 that shit wont [email protected]

What you also have to remember is that the oil here is at higher temperature from the intercooler. Your intercooler will got hot from the air coming out of your turbo and this oil is also under pressure making it easier to ignite. The conditions in the intercooler are very different to though at room temperature and pressure which you have tried to ignite.

Temprature is not a factor in the oil igniting because the intercooler doesn't get very hot. Infact its fairly cool most of the time. If the intercooler added heat we wouldn't use it to cool the air. So I still stait my point you could boil the oil and still would not light by itself. The only thing that causes oil to burn in the compustion chamber is the gas explosion. 4cycle oil is designed not to burn. Two cycle oil is a diffrent situation.

Yeah ok, that was just what I was told by a turbo specialist, that this can happen in rare cases. As for the intercooler not getting hot, i think it does as there is air going in there at 100+ degrees C. Much of this heat is transferred to the environment through the intercooler, so the cooler will get warm, just like your radiator.

My turbo when out at about 60K miles. Found a good used on in cali., then I found www.geocities.com/knightturbos. They sell and upgrade for around $650. It is a little bigger turbo. You can also rerought the oil line going into the turbo, to bypass it. Just don't run the car to long like that, it is just temporary. I also got a larger cooler for the air going in. When you get a new turbo, make sure you let it cool down before you turn of the engine. That 30sec. - 1min. that the manual tells you to do isn't enough. As for the oil igniting, it won't happen, when that seal blows out, which it did already, it pours the oil right in to the air going in. That is to much oil to ignite. Plus I would like to know how to get the oil to ingnite that far back in the intake, your car would have to be on fire. Or you got the new makebelieve sparkplugs that go before your intake.
