318 LA rebuild after losing a valve seat
I used a 50/50 mixture of STP and 30 wt motor oil as an assy. lube.
From post #77 ---- the rod bearings are incorrect. The bearing tangs must be on the same side. The other sides are plain on a 318. The other sides have a V notch on the 340's.
From post #77 ---- carefully remove the oil rings from the piston. See if the outer rings are still flat. You may get lucky.
Keep up the battle.
