Re: 89 EC25 3pg rebuild questions
Splitting the cases is free, if it's already out and the top off.
Main bearings are cheap and a common item.
Rod is supposed to have a lot of side clearance at crank end, it's guided by piston and the spacers on the top end pin. It may just be a worn wristpin, easy to measure or slide so the part that normally rides in the piston, is in the bearing area, and wiggle up and down.
I'm not a fan of the drastically lean oil ratios these call for. Oil migration in a low-rev engine allows lean ratios, but I think they'd live longer with twice the oil, especially if hotrodded.
