Have you already done compression/leak down test on that motor? i thought TScomp motors were well built and didn't burn any oil.

You need to measure how much oil pressure the turbo is getting.

However, using 1qt every 500 miles is a lot more than just turbo leakage.

120/105/120/120 using my old head that was also low on #2, I doubt the shop refreshed it before putting it back on. The numbers don't change w/ oil, the consumption is probably a mix of things like valve guides + turbo + something

Yeah worth a look. It's 1qt between 500 and 1000 miles, depends on the road/highway/driving style/mystery variable. It improved a lot for a few months, and then started again, I'm clueless.
