Richard,

I checked the bolts today and the 1" bolts extend 1/2" from the bottom of the adapter and the long bolt 3/8".

You can use these measurements to determine if you can get it off.

Rob,

I was told off line by someone who would know that it can be done with the manifold in place, but it is a tricky operation. You only have about an inch to play with and the orientation of the gasket is easy to mess up. My problems might have been caused by my not using lock washers for those three bolts when I finished putting the engine together before I installed it in the coach. Over time they loosened up causing the leak. It took 30,000 miles or so to do that. I was in a hurry to get it done and wonder now what else I screwed up during the install.

I need to get it done this week since I plan on leaving for Wisconsin on Sunday.
