Hi guys,i'm new to the forum but been messing with toyotas for a while. I just started working on a project car(1974 toyota corolla) that we put a 7m on it but after a couple of runs on the dyno the motor started making a sound like it had bad bearings or a knocking sound(the engine is a new rebuild and all clearances were right) also the oil press is 90psi cold @ 1000rpm and 35 at 700rpm .Having no previuos experience with 7m's before (mainly 3tc and 22r)what should i look for before disassembly of the motor.Any suggestions/past experiences from you guys are greatly appreciated. Thank you.
