Dear all,
I have a big headache because of my 1.9 TDI. I'm talking about a Audi 80 1z, fitted with bigger injectors (0.205 from AFN) and VNT 17.
It has started to smoke white from the exhaust. I was looking underneth the car and I saw oil coming out from exhaust assembly points. At that moment car was running great, lots of power and fuel economy, but the turbo had the "police car sound".
I said ok, this means time for a new turbo. Got it rebuilt, with Melett CHRA, but the smoke still persisted. White smoke was still present during idle, and on low accelerations after idle, on warm engine. When engine was at normal operating temp, smoke was less the initialy.******CHECK VIDEO
I swapped the injectors, same problem, meanwhile got my injectors tested, and the result was a PASS.
I did put back the tested injectors, swaped the CCV valve with a tested one, but still problem persisted.
Before the new turbo, I did a compression test on the car.
ENGINE was really cold (turbo was already off so I couldn't start it), temp was 6 degree celsius and I got the following values:
No.1
26 bar - 380 PSI
No.2
27 bar - 400 PSI
No.3
27 bar - 400 PSI
No.4
26 bar - 380 PSI
JUST TO MENTION AGAIN, engine was cold - car sitting over night / outside temp (where the test was performed was 6 degree celsius)
Can someone please help me with this problem?
I'm suspecting valve seals?????
P.S. I attached a youtube link with the smoke, until second 25 car is warm, after car is at normal operating temp.
