Losing turbos...HELP!!!

[AWD97DSM]

I have gone through 3 turbos in the last month with oil changes inbetween each one. Oil pressure is ok wating on an oil test. I am wondering if moving the oil feed line supply down around the oil filter will help. Does the stock location supply enough oil pressure for a ported big 16g? I am running 20 lbs of boost with supporting mods. What else besides oil issues would cause a turbo to fail? I do have a turbo time from blitz. Any other advise on keeping a turbo in good working condition would be very helpful

Any of those TD05 turbos should be fine getting oil from the cylinder head. Have you taken a look at the oil drain tube to make sure it's not blocked? Are the coolant lines hooked up to the turbo? What kind of oil are you using (not the brand, but the weight)

By chance have you used the same oil feed line on all the turbos? Have you tried to clean it out? it may be clogged

Where are you getting these turbo's from? I would definatly check the oil lines out and the water lines to make sure that there are nothing wrong with them. What type of intake do you have? How is your air filter?

And I'm sure you prime the turbo's first...

Just for some clearifacation
By prime he means to take out the MPI fuse and crank the motor for about 10 seconds.

the oil drain tube is brand new and all the cooling lines are hooked up. and yes these all have been td05h's. I will check the oil feed line to see it if is blocked. I know the cooling lines are flowing well. And yes I did prime each time. I am using full-synthetic 10w 30

i have just recently charged the k & n filter. It has the 1g intake manifold and the stock air intake

from what others have told me you should only use oil from the head if your using a ball bearing turbo. If I were you Id get my oil supply from the oil filter housing, do you have an aftermarket oil pressure gauge? You have good oil pressure? Also where are you getting these turbos from, and if you have an egt gauge keep an eye on that you might be overheating them. I have a post on here somewhere about my story when I went through 3 turbos in a month. It turned out to be a fluke, the t25 was old and time to go, the next turbo was an ebay turbo and went in like 2 weeks, and the 14b I left at the 16g boost pressure (20 psi) and overheated it. You need to make sure your properly priming the turbo as stated above, just out of curiosity how much boost are you running? And whats your milage? If you can get away with it try using a little heavier oil. Worth a shot, Good Luck.

Yeah I'm wondering if all these are the infamous "ebay turbos".

 

[AWD97DSM]

well the last one was an ebay turbo i learned that one ...the engine has only 6,000 miles on it and i am running about 20 psi with the evo big 16g. what is the best way to keep a turbo from overheating at 20 psi??? there has to be a way... i am going to switch the a holset this winter...and i plan on moving the oil feed line...i also know that they dont overheat and are not liquid cooled...how is that so?? thanx for all the help so far

 

[blackbyrd]

i also know that they dont overheat and are not liquid cooled...how is that so??

Are you saying your 16g isn't liquid cooled?
It's cooled by both oil and your engine coolant.. Did you not have coolant lines hooked up to it?

what fuel mods are you using for that e316g, make sure your not runnin lean, that will overheat the turbo.

Have you checked for obstuctions in the feed and return lines.

I don't think that works. I've cranked my car over with the oil feed disonnected from the turbo(blown 16g) and nothing came out. I don't think there is enough RPM to build oil pressure in the head when the engine is cranking.

How would you reccomend priming a new turbo?

 

[Defiant]

Use an oil can to pump oil into the feed tube, then re-attach to the head. Use a piece of tubing to feed it into the hole inside the banjo fitting.
But I don't think that's your problem.
