Timing Belt Replacement Question
Almost ready to replace the original timing belt on my 2001 allroad 2.7t (80k miles) and I have a question about locking the cams. I have the driveshaft at TDC, but the cams are both about 15% short from rotating to the horizontal position...where I can then install the cam locking tool. I was surprised that the cams didn't line up at TDC (with the large hole on the cam on the inward sides). Question: Should I rotate the crankshaft off of TDC to align the cams? OR, should I take the current belt off and turn the cams to the locking position while keeping the crankshft at TDC? Not sure which way would be correct. Can the 2.7T operate when the timing is apparantly off by this much? Car ran fine and I thought this cam locking process would be straightforward. Any words of advice before I ruin something badly?? Thank You!

It is currently not timed properly.
Use the cam lock tool to lock the cams at TDC, remove the timing belt, then slowly rotate the crankshaft to TDC and lock it in place. Now, replace the timing belt and adjust the tensioner to tighten the belt. Remove the cam lock and crankshaft lock and rotate the crankshaft by hand a couple of times to ensure that there is no interference and that the timing at TDC has not changed. |

Did the car run ok? By TDC your going from the mark on the balencer that lines up with the arrow on the timing cover. I would just make it so the cam bar can go on it and correct the crank when preparing to reinstall the belt.
