Would Oil Analysis Be Likely to Detect Unsafe Bearing Wear?

Post by CBogle »

Dear Fellow Members:

In another thread, Bruce Fenstermacher mentioned that when he removed the rod bearing cap to visually inspect the bearings, they were almost worn through to the babbitt. My question is, would oil analysis, if it had been done consistently with each oil change over a long period of time, detect this type of abnormal wear? If so, does anyone know which element(s) would show up outside of the normal range?

Thanks,

Curt - N4288V

A great source about oil analysis and oil filter analysis is available at: http://www.sacskyranch.com/cancut2.htm and also an article on bearing wear: http://www.sacskyranch.com/eng219.htm

The Sacromento Skyranch has a lot of good maintnance articles in it "Knowledge Base" section.
