Ok guys. I did my extensive testing tonight with a much larger compressor. Filled compressor to about 35psi so i wouldn't overdo it with too much.

Test #1, same test as last night. Put boost leak tester on turbo inlet. Could hear
blub--blub--blub--blub--blub...etc...down in the oil pan. --- Was also hearing another leak too.

Test #2, put leak tester on t.b. elbow.
Result-- No more blub--blub in oil pan. Was hearing a pretty strong leak on the throttle body butterfly valve right were the recoil spring is. Leaking pretty good all the way around. Sounded like a leaky air hose fitting.

In both tests, air leaked out right away. Could not build up any pressure in either test. So i got 2 nice leaks. The turbo leak would probably account for the oil i smell. I don't really see smoke but i can smell the burning oil.

So... do i just need new oil seals for the center cartridge of the turbo or do you need all new bearings, etc... Turbo less than 4k miles old. Is this something that i can do myself or does it need re-balancing afterwards? I know there is probably a warranty but i'm afraid to send it to PTE for the sake that it will probably sit there forever.

As for the throttle body, is this generally a seal or o-ring that goes out and needs replancing?

Thanks much.
