Popin' turbo's like pez

[ddavisaf]

I searched. So don't yell

Anyway. Blew my stock turbo. Heard the turbine grinding against the compressor housing. Nice sound. Swapped it for a 14b. No shaft play what so ever. Turbo was good. Put the 14b on. No boost leaks. Turned the boost up to 14 psi. 10 miles later. I blew that turbo. It went from no shaft play to bottoming out of the housing just like the old one.

Oil: I bent the stock 2g oil line to where it was unuseable so I relocated the oil feed line to the 1g position off the head. There was a small leak from on top the turbo (14b) same line. Seemed like the brass washer was missing or something. So there was a *little* bit of an oil leak from the turbo oil feed line. Blades on both turbos are mint condition.

The car is parked right now in fear of me beating it with a baseball bat. I need a starting point troubleshooting wise. My friend told me he's heard that the balance shaft bearings might fall into the oil pan, causing the turbo to blow but that doesn't make any sense to me. I figure you would notice a missing bearing because of vibration. So I'm assuming it's oil related? I run Semi-Synthetic 5W40. 6 bucks a qt. Pretty good stuff. The turbo came off of a 1g running 10W40 non-synthetic (the second turbo, the 14b). Could that have possibly been the problem? No, I didn't prime the turbo because I took it off his car, and slapped it in mine the same day.

I've got a steel braided oil feed line to hook up to the oil filter housing, but I want to know if there is something else that is causing a bigger problem.

Sorry for the length.
Thanks,
Damien

Check your feed and return lines for both oil and water. Sounds like you're torching the crap out of it, so my first suspect would be one or both. Did you get the 1G oil return line? IIRC, isn't the 2G stock one too small to flow the oil like the 14b needs?

Feed from the oil filter with a SS line.

I swapped the 2g oil feed line for the 1g oil feed line. It was a little easier to make work.
So you don't think there is any bigger problem then?

I've got a SS line to install, but I didn't want to risk torching a third turbo within a one week timeframe. I would be torching more than just turbos if that happened.

What about the water lines. Anything I can do to them to make sure I don't blow up my last turbo...?

And for my last question. I don't have an oil pressure gauge, but I will be getting one quite soon now. Anyway. Could the problem be oil pump related? Any way to check other than buying a new 100 dollar oil pump (or however much they cost).
