I rebuilt the turbo when I did the motor used that trader guy kit, the turbo went about 600 miles when the seals blew out, the bearing had basically welded to the shaft. Next I got a good used 14b and had it professionally rebuilt, by local guy that builds lots of turbos. it has lasted about 1000 miles and the seals are toast again, called the professional he said must be a oil pressure problem too much or too little and deny's any fault.
checked my pressure at the filter housing it was 70-80 psi at start-up then went slowly went down to 25-30 at idle after 8 to 10 min. rises about 10 psi per 1000 rpm at high rpm maxed out around 80-90psi. as far as I can tell the presures are good.
the motor is stock with .20 over pistons has balance shafts, turbo is feed off the stock head port.
so far only ran 10-12 boost
What should I check next?
