please help!!

i have just rebuilt my 13b single turbo. been bridge ported. spent over 13K with Mechanic and now i find myself taking it back for the forth time due to oil leaks??

when is enough enough???

one oil leak is in the turbo feed line and the other he cant find seems to be coming from the oil injection housing? he rebuilt engine top to bottom... but i feel like i am not getting anywhere with him. once again i have to have it towed bvack to the shop.... grrrrrrr

 

feel sorry for you man. why dont u take some photos of the leaks and post a thread on the main USA forum. someone will more than likely step u in the right direction. maybe try a semi-sythetic oil instead of full-sythetic. try ringing around all the rotary shops in australia and explain the situation to them, you'll find someone knowledgable eventually that may give your mechanic some key advice... i use motul 10/40 but thats full sythetic and i have a leak out of the turbo im trying to figure out at the moment, but as long as im not losing too much oil im not overtly concerned as long as i have good quality and quantity of oil in it.
