Well the TC is down for the count again,maybe for good this time.I cant afford to keep this thing up.I finally got my detontaion problem fixed for good,I put in a new fuel pump strainer.It was one for a mustang that came with the pump,swapped it out for one for the tc and thats all it took.I just got a new turbo a few months back at a reputable shop,When I got to school this morning my car was pouring out smoke.had to get it towed home,got it home and too off the front part on the turbo and my bearings are gone.I have LOTS of play.This is the second turbo in under a year,The first was a good junkyard turbo,this was brand new.Is 22 psi on a t3 to much?It barley ever seen over 15 psi and if it did it was not there for long.I put a bpv and always let the turbo cool down after I drove it never really drove it hard.This turbo was only about 5 months old.What do you guys think crappy turbo build or oil pressure problems?Ive never had it hooked up to a mechanical oil gauge and I know that the gauges are usally off.The oil feed line was also replaced with a braided line.I know you get what you pay for when it comes to anything,I did alot of searching and calling before I got the turbo,I did not just jump on the first one I found.I think I paid close to 600.00 for it,It was not cheap.Any Ideas?

A turbo does not need a whole lot of oil pressure. no more so than the engine does.
It also doesn't take much contamination to wipe out the bearings. Are you cranking the engine, with the coil disconnected, for at least 30 seconds or more after an oil and filter change? This lets the filter fill up and start pumping oil out to the turbo so the bearings don't starve while the filter fills up on startup.

Ive done everthing to take care of the turbo.Even if I didnt boost it hard,I would still let the car idle for a few minutes before shutting it down.I always cranked the engine over for at least 30 seconds after an oil change and that was the main reason for buying the bypass valve,just to prevent copmpresser surge.Since ive had the car Ive put 5 differtent turbos on it,3 ihis and 2 t3s.Only one was brand new though and thats the most recent to go out.

Did it have any kind of warranty? What brand is it and where did you buy it from? Also it's a good idea to stay out of boost until your engine is fully warm and the oil pressure drops to operating temperature. Turbochargers use the same type of bearings an engine does, and the heat is of no help in the conditions those poor little bearings have to endure. I don't normally even leave my driveway until the oil is up to temperature, and if I have to, I at least wait until the coolant is up to temperature, and take it easy until the oil pressure is down. Then I drive like I stole the car and give her a good flogging [Image: biggrin.gif]

As I understand it a BPV has nothing to do with surge.

$600 isn't cheap. At that price it ought to be right.

Yeah I was actully thinking and I dont think this turbo has more than 6,ooo miles on it.as far as the warranty goes Im going to call tommorow,Im PO about it,this thing should not have went out already.I got the turbo from a place called R&R disributing, its supposed to be a good place to buy from.I do know that the turbo was not a rebuild and was brand new.I do not know who built the turbo,it just says garret on it.My luck its an ss autochrome turbo.It was new though and I babied it for at least 2000 miles to break in my new clutch,I did my t5 swap and the new turbo at the same time.Im gonna call tommorow and see what they will do.Thanks

Well, there's the problem right there [Image: frown.gif] The SS Autochrome turbos are 100% garbage. If they honor ANY kind of warranty, try your best to just get your money back.

Did you replace the oil feed line when you put on the new turbo? If not, you should have. Even a reputable turbo rebuilder will not warranty a turbo when used with an old feed line.
