Mike: If the engine is removed from the truck for repair, would you recommend the modification that moves those two bolts that can only be accessed by removing the oil pan to bolts going in from under the timing cover? I've done this on a GMC engine and I think the procedure would work on a 235 Chevy as well.

Update: Bolter SlimSix (Andy) did a nice write up with pictures on this modification 20+ years ago on the OldGMCtrucks web site. He states "this same procedure applies to the Chev 216's, 235's and 261's".
