Just finished installing an oil cooler and cooler housing replacement, and I'm getting a tic tic tic light noise at idle, which turns into a loud metal shrieking soon after turbo light goes on and around 2100rpm- admittedly I didn't prime the turbo as it was still oily, and I did re-route turbo cooling outlet hose as I cant find a replacement in/out water pipe. [under the thermo housing I blocked off the 3/4in heater hose [in and out] and routed the turbo water out to the bottom of the radiator as I thought it would flow out there ok]..
The turbo sat in a box and was working fine before the rebuild! All gaskets are new and sealed up good, new exhaust manifold gasket. Only thing I can think of is the exhaust down pipe which I think might be not tightly/properly reattached as I did it in the dark in the rain and rushed that bit. Otherwise have I buggered the turbo bearings due to not putting more oil in before first start???
