Here is some quick background; Purchased flying RV with documented engine rebuild with performance mods. After two intake valve failures (One with the previous owner and one with me) I decided to have an IRAN done by the local shop. I have posted before about some of the questionable stuff like the regrind of the factory camshaft etc.
Something that I found interesting is what appears to be the use of some old questionable parts during the overhaul process. I've attached some photos of the main and connecting rod bearings. These are on a 400HR 0-320. I am somewhat new to owning this model of aircraft engine and wondering if this shows excessive wear for a low time engine.
Thanks!
