I have spent hours reading and I am more confused now.
Few questions...
I have found that the engine needs to be a certain number of degrees BTDS when installing the new IP. The IP I currently have was removed at TDS, and I have just done a valve adjustment on my engine.(1981 300td) looking at the balancer it shows a reading of 10.

SOO..
1) if the engine needs to be at 23 BTDS to install the pump, what should my reading show since it currently says 10, but I know its at TDS on the crankshaft marks?

2) So whats the big deal if its a little off? I have found people that have timed them a bit off on purpose.

3) If I screw this up, do I have to take the IP off again to do it right....I NEVER WANT TO TAKE IT OFF AGAIN..(if I actually get it back on)
