Unfortunately, I’ve been spending all my spare time either at baseball or working. However, we’re getting back into the groove today.
Cracked the heads off and pulled off the oil pan – it’s a 4 bolt main (figured), and visually looks great. We rotated the pistons again and watched for knocking and clearance on the rods – no knocking and the clearance looks perfect.
A few piston skirts appear to have rubbed against the bore – I think they collapsed, but won’t know for sure until I measure. The bores otherwise still have crosshatching which is slightly surprising. I really want to reuse the pistons and rings and am hoping I don’t need to bore this. There is a ridge at the top of each cylinder bore, so again, assume we aren’t having to bore this out, honing will clean that up.
The cam is getting thrown away – 2 of the lobes are practically round!
Because of all the sludge, we pressure washed the block thoroughly with hot water and purple power degreaser.
We are going to remove the bearings a different day.
