Aloha All,
The engine in my TR3 has recently developed a rhythmic knocking noise, like rapping a knuckle on a hollow core door. So my initial thoughts are that I have a bad connection rod bearing or main bearing. If the engine is cold, the noise is not apparent but appears as the engine warms up. Listening with a mechanic's stethoscope I really can't hear any knock. I spent the weekend checking nuts and bolts to make sure it wasn't a door or hinge making the noise.
Before I tear down the engine are there any other things to check or possibilities that might make this noise?
