Engine oil sludge?

Usually caused by lack of oil changes or operation of the engine with under less than ideal conditions like:

  • Short runs that do not warm engine completely
  • Poor quality engine oil
  • Engine has something wrong with it so it does not run correctly

This will cause excessive wear and engine failure.

To prevent damage

  • You need to do more oil changes and repair the engine so it runs correctly
  • A badly sludged engine that has not yet been damaged will need the oil pan and rocker cover(s) removed and the sludge and the crud cleaned out correctly.
