Yep Pat, firing order is now 351 order because of the cam. I also looked to see if anything like rod bolts or connecting rod is coming close to anything, couldn't see any problems or scuffed areas where something had rubbed. Counterweights are not near piston or bore. I examined pan and dipstick too to see if they were getting in the way, no marks or anything.

I am seeing some metal particles in the bottom of the pan. Looks more like machining left overs than bearing material. Not a lot of it, and I just wiped out the pan when I did the galley plug replacement. Not sure where that black dirtlike stuff is coming from. I've changed the oil twice already, running Rotella T 15-40 with Comp Cam break in lube too.

What do you mean .008 is "thin?" Is that tight or loose?

Thanks for the help Pat.

Don
