Tilting the pump
- Thread starter lisab4
- Start date
Timing is perfect. But it won't even start at the moment. Just lots of white smoke when trying to start. Think I'm gonna ask a specialist shop to fit a rebuilt pump. I'm in over my head 
Stupid thing is the hardest part worked fine. Replaced both seals and that job went perfect.

On a AHU or 1Z tilting the top of the pump toward the front of the car retards timing.
Putting it another way, rotating the pump body the direction of shaft rotation retards timing.
You may be looking at info on the AHU where rotating the shaft of the pump CW or "toward the front" advances timing.

Have you tried advancing the pump one tooth? I've had to do this with my 1Z in the past.

Maybe but was it timed ok before changing the seals?
Did you remove the pump to changes the seals or do it with the pump installed. If you didn't remove it the timing shouldn't have changed when you replaced the seals and you probably have a QA position problem.
Did you tilt it back as far as it would go?
If the timing is off too far VCDS will say the opposite of what is really happening. Too retarded when it's actually early.

White smoke I believe indicates overly retarded. However, the adjustment range of the pump tilt will not produce rough running at either extreme of the range in my experience, which indicates that you might have a tooth off on pump timing.

Rotating the gear CW from the pinned position advances timing

Yes, rotate pump sprocket toward the radiator to 'advance one tooth.'
Alternatively, I have never advanced one tooth, I've just pushed down on the pump sprocket holding pin (when it's in place) to get the belt installed at the correct point.
You want zero slack between the crankshaft sprocket and the IP sprocket.
Good luck
