Okay, just finished having a look at all the timing marks. I lined up the main ones on the crankshaft pulley with the plate next to it and found my dowel pin on the IP gear to be at the 4 o'clock position...perfect. Then I looked at the markings on the IP and gear housing but found the IP was out of alignment counter-clockwise by about the width of the mark, not much but will this affect how the motor starts or runs?

How it runs, maybe a little.
Shouldn't be enough to significantly affect how it starts though...
By golly I fixed it!!! I loosened off the 3 bolts holding the IP onto the housing and twisted it until the marks lined up, then tightened the bolts back up. The bad miss I've had when it starts for the past 5 years has now disappeared...for now, I'll try again in the morning to see how she starts.
OK you guys. I have read with great interest all the posts about timing your IP. My question is..Does the timing need to be changed for high altitude? How do I know what the cetone of the fuel I am burning is and does that make it necessary to change the timing. What about BioDiesel verses #2. Is that going to nesessitate changing the timing? My 93IDI turbo 7.3 runs good. Should I check timing or do you do that when you change the IP? I travel to the Rockies every year towing a 5th wheel from Fl. do I need to worry about changing the timing?
