This thing was build in Nov of last year before Tall Pines.
Just recently, it over heated once at a shakedown/track day, but after burping the coolant temps came back down to normal and stayed there. The next weekend, ran 5 stages without issue, then on stage 6, temps way back up.
Assumed a blown HG (basically knew this going into the rally, and figured it would make it), so i disassembled, and found HG's leaking in more than a few places.
Loosening off the ARP studs to pull the heads, the studs were "loose" and tossing an allen key in the studs, i could turn them in 2-3 full turns before bottoming in the block. So HG problem solved basically.
Figured to rip apart the bottom end, toss in bearings, have a look at everything, and some rings...why not the parts are "cheap" and good preventative maintenance now.
As you can tell from the pictures, there's some pretty serious wear happening.
I'd believe that tuning and detonation will cause the rod bearings to wear out...but the Mains are where most of the wear is happening...
Looking for an opinion now, to atleast shoot me in the right direction. I may be over critical, and it is safe to just toss in new bearings, give the bores a hone and some rings. But i'm just not sure.
