slowteg550

My car has only idled for a total of 20 minutes probably with a 3 an feed line to a gt3561s and its leaking oil out the exhaust side. The turbo is brand new, and i've gotten close to 80 psi of oil pressure by just revving it to 5-6k. My drain is made around a topmount manifold, so it's not straight down, but it doesnt have any 90 degree turns or uphills either. I read that all gt series turbo have an oil restrictor built in, if that's the case then what could it be?
