prime the oil to the turbo?
disable fuel, crank engine until oil light goes out
Ive just got some 'DIRKO' sealant for the sump,as that will be taken off and cleaned as a precaution,,,,,,,,,,any ideas of what the torque settings are for the sump bolts and also the bolts that go onto the manifold that holds the turbo?
You shouldn't have any issues re-using the copper nuts when replacing the turbo.. I've swapped mine a few times and used the same nuts.. Only thing you'll need is a new exhaust gasket. Also keep an eye on that oil feed line, they are a bitch to get off without twisting and cracking them.
If you pull any studs out of the head, any stud from a 8V gasser or diesel engine will work. They are all the same.
The turbo should come with instructions. Typically you add oil to the feed port and spin the turbo until oil comes out the drain. I think some manufacture recommend that you not hook up the drain line and after pre-filling the turbo as mentioned above, you then crank the engine over without allowing it to start until oil flows freely from the oil return. This also will verify that the feed and return lines are not plugged.
I just got my turbo reconned and they said to fit without connecting the oil return hose from the turbo to the sump, disconnect the injector wiring and turn over until the oil is pouring out of the return pipe remember something to catch it in or you get a meesy floor.
all done just dont understand 1 thing,the black box next to the battery were all the pipes go into theres a hissing noise which gets louder when i accelarate......i unplugged it and 1 pipe has good suction with the car running......the rest do nothing which i think is normal.......whys it make alot of hissing?
believe it or not, i ALWAYS fire up my engines with no return line on the turbo, and a drain pan under it, just to verify that it is indeed flowing oil..
i always oil the bearings WELL before i even install it on the engine..
it has also been suggested to HOLD the compressor wheel from turning with some sort of soft object that will not damage the compressor wheel..
(i use my finger to hold the compressor from turning, then fire the engine, and let the wheel go when i see oil coming out of the turbo drain)
the pipe that has vacuum with the engine running, is the air intake for the engine. the one that has no vacuum, is the boost outlet from the turbo..
are you running with no intercooler, or with a leaking intercooler?
boost leaks are HARD on your turbo.. they allow it to overspool pretty bad..
Maybe a picture of said black box? The only "black box" I know of in at least our Jetta TDI near the battery is the airbox. But I have no clue about the 2.0 TDI
