Dear muskox37,

Hope you're well and stay so! It sounds like a broken valve spring. The post-1992 B230 engines have oil squirters, to ensure generous lubrication.

Unless the oil has become sludge-like due to neglect - out-of-character for you - it is highly unlikely that a rod bearing has seized or had "spun".

Even so, I'd check the oil level. An overlooked road hazard could have punctured the oil pan. If so, oil starvation could have caused a bearing failure.

Far less likely, an oil pump failure. I've never seen such a failure report in some 20 years of reading BB posts.

Please post-back with your findings.

Yours faithfully,

Spook
