Chasing down a loud engine knock in a Land Cruiser
From time to time I do work on cars other than Mercedes Benz. Sometimes it is painful and in the process, it reminds me why I like working on Mercedes. So was the case when I took on working on a 1997 Toyota Land Cruiser with a loud engine knock. This knock piqued my interest because it sounded like it was moving around in the engine. At first, it sounded like something in the valve train. As we progressed with our diagnosis it sounded like it was a piston or wrist pin. When we finally removed the oil pan we realized it had to be something serious.
