Wrong Bearings & Crankshaft Play! Toyota 1ZZ Engine Overhaul and Fix

"Hey everyone! In this video, we tackle a Toyota 1ZZ engine that came into the shop with a serious knocking noise. The owner had just picked it up from a previous mechanic’s overhaul, but after only two drives, the strange sound began. After inspecting the engine, we discovered that the wrong bearings and thrust washers had been installed, causing crankshaft play and that bad knocking sound. Watch as we take you through the full disassembly, diagnosis, and repair process, where we replace pistons, install new rings, a head gasket, machine-polish the piston sleeves, and more. Learn from the mistakes made in this overhaul and see how we get this engine running smoothly again. Don’t forget to like, subscribe, and leave a comment to let us know where you're watching from!
