hi all, 'ive got a slight problem with my skyline rb25 turbo, car was driven and abused from time to time for number of months without a hassle , recently turbo was gone so was fully rebuilt with rebore internals,new stronger and balanced shaft and seals, new engine oil was put in the car as well,after fitting turbo went for test run and all was perfect (boost is setup to 1 bar) after 20 miles started smoke, losing bit power on high revs and spilling oil thru exhaust , lost nearly 3lof oil in few minutes ,is this possible that turbo is gone again? all hoses were fitted correctly and checked before test run ,compression wasn't done yet, any ideas?please help -thanks
