Wow, it has been just over 3 years since I posted anything on this thread. Bringing it back from the dead.
So, since the car was put together the last time in order to move it out of my dad's recently sold house, and into the garage of the house he is renting, the car has sat in the garage since then. the more it ran, the more pronounced a rattle became. I couldn't drive the thing like that, plus the oil burning issue was getting worse. I through my hands in the air and walked away and focused on my home renovation, and my job. I just needed to forget about the car for a while.
I finished the renovation and have it on the market currently. I have also recently applied for a Field Service position in the company (Military Contractor) I work for. If all goes to plan,and with a little luck, I will be living overseas making 3-4 times as much.
So I decided to come back to the car and try to fix the 2 problems I have been fighting since it got parked. first, the rattle was the newly done head I had a machine shop do work on. needless to say, they were morons when it came to these heads. I may as well have flushed all that money down the drain. I don't know that the head is garbage or not, but I decided to put the original AAN head back on the block. I also took a hard look at the turbo and came to realize the oil was coming from the turbine. I had Industrial Injection rebuild the turbo and put the car back together, changed the oil/filter, changed the fuel, and fired it back up again.
The result was the rattle disappeared, aside from the (anticipated) lifters pumping up. However, the turbo is now pumping oil out the turbine faster than before.
So forgive my bad memory as I have used my brain for testing and debug of electronic devices I cant go into, and the thought processes on the old Audi's gas gotten a bit rusty. I have a feeling the turbo is getting too much oil pressure, but I don't really know where that should be regulated. is it in the oil pump, or the filter housing. I need to connect my pressure gauge up to the feed line of the turbo, but since that is still original, it may be tricky. I would rather not yank the turbo back off just yet to go yell at Industrial Injection before I check the basics. Can somebody point me in the right direction?
And since everybody likes pictures, here is the latest pretty pictures of the engine.
