Well the 2nd IHI turbo has went out on my zc. Both turbos that were on the car had no shaft play when i got them. One lasted about 200 miles before it stop boosting. So i bought another and it lasted about 120 miles. Im sick of wasting money so now im thinking its my oil line. I teed off the back of the block homedepot style, but then i used a rubber gas line from there to the turbo. Ive took the oil line off while the car was running and its getting plenty of oil. I dont have a oil pressure gauge so i dont know how much pressure it has for sure. Today i got my Tunertoys oil line kit in the mail and i noticed how small the inside of the oil line is compared to the gas line im using. So i was thinking the gas line im using caused the pressure to drop and it wasnt getting the oil it needed. Just asking for some opinions or what any of you all think.

The gas line im using the hole inside the line itself is fairlly big i could probably stick the tunertoys oil line inside the gas line.

 

I think that might have been your problem, the feed line beeing too big (without at least an oil restrictor). I think you were getting too much pressure and blow up your seal as a result at the end. That's just my opinion.
