Engine teardown results, would appreciate your thoughts
This is a long nose 1.6 with 122k miles I'm prepping for boost. It's already run on boost, up to 4 pounds with a gt2560r and megasquirt and did just fine. Tearing it down for inspection and install of Manley rods to shoot for 250 whp. I want to reuse the crank and pistons but want your input first. Don't know if this is normal wear or if stuff needs replacing. I'm happy to provide and information and pictures if you want to see more/something specific. This engine has no sign of rodknock, just a shit ton of lifter tick. All the bubbles you see on the oiled surfaces are just oil doing funny stuff, not pitting. wiping it off with my finger results in a smooth surface. Every bearing has no play and every surface feels nice and smooth. Crosshatching is still visible in every cylinder. Not sure if I need to resurface the block or head. Pistons came out very easily, just needed a tiny tiny tap from a wooden dowel+rubber mallet to get the second rings past the cylinder top buildup. I can feel no ring ridge but clearly its got carbon buildup and such. Top of the pistons are filthy. Here's my plan next, please let me know if I need to do something else. Thanks so much
Plans going forward- new OEM head gasket, rod bearings, piston rings, reuse pistons and crank, reassemble and send it Important!!! Videos inspecting crankshaft, pistons, and cylinders available here at these YT links below.
