Not a Z update, but have stripped the Toyota 18RG twin cam down to an almost bare block. Almost because I ran into a snag. The engine had, it seems, been decommissioned it some point due to a head gasket failure, with lots of rust present in the top of the #1 bore. The piston doesn’t want to come out because of the surface rust; worse however is that it was obviously left wet for some time, and the bore, where I’ve been cleaning it, has some fairly nasty pitting. Now, I’m going from 88.5mm standard bore to 92mm for the 2.2L pistons; this may be deep enough to remove the pitting, However, if not, the project cost will shoot up as it will need a liner fitting…
