yes, brand new Egge with 1-1.5hrs of run time. The flash from the camera really makes the wear look dramatic. Maybe that's the best way to look at it, but doesnt' look that bad with the naked eye. I took piston 1 & 2 to the machine shop today. They said it was more than expected for that run time, but not so much wear to concern them to do anything about it. Mic'd the pistons and skirts and they were right on. Said they were more worried about the fact that both the lifters for piston #1 were not rotating and to concentrate on figuring out if it was issues with the cam lobes, lifter pre-load, push rods etc causing that.

He also cautioned about drawing too many conclusions on these symptoms with the limited run time so I should fix the lifter issue, get it running and drive it to get more time/miles on it; then reassess.

I have seen zero evidence of any paper towel bits wherever I clean so I think I'm going to start putting this thing back together after I convince myself I've got clean lifter bores, good pre-load etc.

Was anyone able to open the zip file with the audio file of 'the noise'? Curious as to what others think it sounds like (metallic impingement, squeaking, etc)

thanks for reading
