Can a spun bearing cause a car engine to fail?
Engine Bearing Technology – The Spin on Spun Bearings One of the worst failures that can occur inside an engine is a spun bearing. It can happen in a stock engine, race engine, gasoline engine or diesel engine. A spun bearing is bad news because it usually seizes itself around the crankshaft journal.
What happens when you spin a crankshaft bearing?
A spun bearing is bad news because it usually seizes itself around the crankshaft journal. What happens next depends on the bearing’s location. Spun rod bearings are the most common failure. A spun rod bearing will tear up the big end bore in the rod, ruin the rod journal on the crankshaft, and sometimes break the connecting rod.
How is crush fit determined for engine bearings?
To accurately determine crush fit, bearing manufacturers use a special block gauge to measure the bearing after it has been installed in a bore with a known size the cap has been torqued down to specifications. If crush fit is correct, the bearing will be held snugly in place without too much deformation that could cause clearance problems.

What happens when you spin a cam bearing?
The damage is usually limited to the main journal surface on the crank and the main bore housing. A spun cam bearing will tear up the bearing bore in the block (or head in the case of an OHC cam), and possibly snap a timing belt or chain – which may result in one or more bent valves if it’s an interference engine.
