Valve stem seals?

Kuban · 03-26-2007, 11:56 PM

Well update! i was on way home from work today and i live about 20 miles from home. I was on the freeway about half way home and i looked behind me! Well the street was filled with coolant. So i pulled over as soon as i hit the next exit. By that time the needle was pinned above H. I parked, opened the hood. One of the upper heater core lines blew. So i tried pooring coolant in, but it was soooo hot it boiled right back out of the car. Sooo i waited a while, fixed the line, then filled it with coolant. Drove it home, and about a mile from home i gave it a little to see if i blew the hg. You know spool a bit to see if the temp rises. But no everything was good. Temp normal, everything normal. Until the second time i did it and my turbo sounded like a supercharger......

Im assuming when the car overheated and i was driving for those 2 miles or so, the turbo overheated and burned up the bearings. So when ever it starts to spool, it makes a crazy grinding noise. And smokes likes a bitch!
My assumption was the turbo bearings shot.

Could this have been my problem all along? Could the turbos bearings have been bad all along? Causing me to periodically burn oil? And some how cause my pcv to recirc bunk ass oil.

Wow, sounds like you had a fun time.

Yes, if your turbo seals are shot, you will burn oil like your rings were bad. So I think it was your problem all along. (why didn't I think of that!)

That sound you hear is your turbo dying.

As far as overheating, if the heater core hose blew and THEN it overheated then that would explain it. If it overheated and THEN the heater core hose blew, well then you have other issues.

My car overheated one day, I changed the thermostat and beat the shit outta it on the highway then next day and it didn't overheat. The following day I was driving and then out of nowhere it just pegged to the H and my aftermarket gauge read 230F. Thats when I got fed up and started my head gasket repair.

yea the heater core hose blew initially, cause i saw the coolant behind me on the freeway (people getting out of my lane hahaha) and then the temp rose about 2 miles later.

I looked at it and one of the plastic male to male adaptors for the heater core i used melted on one side causing it piss all the coolant out into my engine bay! i got a new one of those, filled it up with coolant and she was ready to roll!

But when i drove about 10 miles, i heard the turbo doin that shit.

Yea im assuming this was the issue all along, although would that cause those pcv issues i was describing?

Yes, if the turbo seals are shot, oil will get into the turbine housing and burn and oil will get into the compressor housing and neatly distribute itself all over your intercooler piping and intercooler.

Now when you ran the motor without coolant I'm guessing the turbo took the brunt of it. Seeing how turbo's get so hot its not even funny, so without coolant cooling it, the bearings will be destroyed in short order.

hmm okay man. Maybe ill try just replacing the turbo and see how that goes. My friend has an extra i can try. If that doesnt do it ill replace the engine with a new built one. How much does a built mkiii with 550-650rwhp go for? Magenta color, mkiv rims, targa, body is immaculant. Apexi 7 way adjustables, eibach springs, new pads, new rotors, 285/40/17 tires in back, 245/45/17 tires in front, map-ecu tune. Ill list more later, but can i get like 9 maybe 10k for that? If its properly built?
