As I tore this engine down, I suspected it to have been rebuilt before due to the liberal use of orange RTV on everything and one-hell-of-a-blue-sealant holding the heads on (plus the nose of the crank looks like someone turned it over with a pipe wrench). I confirmed that when I pulled the pan and flipped it over this evening.
The rods and caps have already been number-stamped. What’s interesting is that they go 1, 2, 3, 4, 5, 8, 7, 6. Whoops. I can’t decide if I should leave the numbers and plan to put them back right or if it would be best to just leave them out of order and re-stamp 6 and 8 as 8 and 6.
For the curious, the bores seem okay, with minor scoring and very little ridge. If I’m really lucky I might not have to buy pistons.
