I'm still piecing together the history on my donor coach, and the last question is the engine.

It was rebuilt by Rettig Brothers in Modesto, CA.

Does anyone have any experience with this company?

Also, is there a baseline for oil analysis for the 455? We always analyze the oil on aircraft, so we have a known baseline. I've done oil analysis some automotive engines that I've built, and learned that it's almost always better to have some baseline for the power plant under scrutiny.

The engine runs strong and smooth, the oil pump is questionable (and would be replaced), but based on compression numbers and a lot of time peering through a borescope (high definition/digital... actually made for medical procedures - thanks to my neighbor), I'm willing to bet that the tolerances are spot on all around the internals of that engine.

It's going to come out, and the mains and rod bearings will be carefully checked, as will the valve train.

Being of the "if it ain't broke" school, yet wanting to avoid problems on the road, I would appreciate input and experiences.
