Zero Oil Pressure

Lack of oil



A couple of weeks ago I shared some information on a recent job, where we weren’t seeing any oil pressure when running the engine.

And last week we got a stark reminder of how quickly things can be affected if the lubricating oil is not circulating.

If you missed the article you can read it HERE.

We were carrying out an initial test run on a rebuilt engine, and straight away it was flagged up that there wasn’t any oil pressure, so the engine was shut down after less than a minute.

We fitted some extra gauges to try and determine the cause of the lack of oil pressure and ran the engine for another minute.

Again, no pressure.

After carrying out some further investigations and checks, the engine was started for the third time.

Again, no oil pressure.

To diagnose the cause, we began a more intrusive examination, here is what we found:

No oil in crank

After just 3 minutes of running the crankshaft was badly scored and main bearings needed changing.

If you are ever experiencing lack of oil pressure, make sure it is checked out ASAP as it can quickly turn into a failure.
