Cam timing in the 10V turbo motor / windage tray

Thanks for the help everyone. I took a look and it seems that it was off by a tooth. But I only was able to use the
marking on the harmonic balancer. I couldn't find the mark on the transmission. Where is that supposed to be?
But now on to my real problems... I decided to swap the cam while I was in there and just my luck, I dropped one
of the bearing cap nuts into the oil return passage on the head. I'm hoping that just goes straight down to the oil
pan... at least that's what it sounded like it fell into. Draining the oil didn't help, so I unbolted the oil pan, but I
can't get the oil pan off for some reason. I have one of those windage trays installed on there, and the tray along
with the lower oil pan gasket is stuck pretty good onto the oil pan even though I didn't use any RTV. Could that be
preventing me from taking out the oil pan, or is it something other than the windage tray?
I don't know what I did, but it looks like the Audi gods have it in for me.

Hi Ameer,
I'd just recheck it. Set the engine at TDC using the flywheel (align the mark on the casting flange inside the window on the bell housing) and NOT the harmonic balancer (rubber dampener could be worn). Now check the position of the cam by looking for the punch mark at the back of the cam. It should be aligned with the top edge of the head.
HTH,

I was wondering if anyone ever had any experience with the cam timing on the 10V turbo motor. I think I may be off by a tooth or two. These are the symptoms I've noticed:
1. poor idle / cold driveability
2. loud exhaust
3. power mostly in higher RPM even with boost; slow pickup
4. poor gas mileage (18-19 avg.)
The engine is in excellent condition: rebuilt motor, rebuilt fuel components, replaced all vac. hoses, and tested all sensors and wiring. I'm going to take a look at the timing belt tomorrow and see if it's off (was going to swap in an MC cam anyway). Could cam timing be the cause of these symptoms? Is there any sense to try different timing positions while I'm in there? How about an adjustable cam gear? Any wisdom on this is much appreciated.
