I have a quick question for a friend. He just rebuilt most of his bottom end after frying some rings and he did a good job with the motor in the car. Replaced the rod bearings with ACL's. New Pistons, New Rings, Honed the cylinder walls, MLS Head Gasket, New Valve Stem Seals. But he did it without pulling the motor or trans. So the Crank bearings weren't replaced. Car started up today and is running good. He has an idle issue we think is the FIAV but I setup his Butterfly set screw and BISS. and he went for a long drive for his first part of breaking it in. So far in my mind the motor is running great, Until he text me asking me why when everytime he presses the clutch, the motor dies........ My only explanation is when he fried the rings, he also damaged the thrust bearing.... Or the thrust bearing is just normal wear and tear but his motor is not strong enough yet. IDK. He still has the ACL Mains that came with his engine kit. So were wondering how easy will it be to do with the engine in the car. I was thinking it possible to pull the transmission, flywheel, and dropping the crank down not unbolting the rods and just pulling the mains and thrust bearing and cleaning the surfaces and replacing them that way. What are your thoughts? This motor right now is halfway in on a break in and the only thing that wasn't replaced was the mains. So he's about ready to tear it down so he can save his break in oil he just poured in.
