So I'm all excited with the arrival of my bearings only to be disappointed when I start to take the wrist pin out of the old #1 piston. It won't move. Uh oh... I take it over to the press, it comes out quasi easily but after I remove it, I find this...
:doh: Son of a... ARGH! What the? Alright, so now lets change the diagnosis from stuck injector to an attempted seize of the wrist pin, which would explain the piston wanting to smack the cylinder wall. But why? The lubraction of the top of the rod doesn't make sense to me, there's a hole in the top of the rod, but other than than that there's a cooling jet squirting oil into the cylinder. How does this thing get lubricated? A slinging effect?
Also, after I checked the other bearings, they are all brassy and all have this interesting "blemish" on them. Is this normal?
