Re: 1991 V3500 Project Heavy Hauler

Problem solved. There are TWO timing marks on the front cover. Don't use the one on the bottom. I was about 45 degrees retarded. Took it all apart, noticed the timing mark up high, confirmed valves on #1 were set properly and away we go.

I noticed my oil pressure is pegged at 3:00 so I think I need a new sending unit. I beat it around pretty good to get it to its new home. Maybe I'll take the top of the intake one more time before we go to get our pop up camper this weekend. I do t like not knowing my oil pressure...

Thanks for the help and suggestions!
