What is normal for bubles/froth in the oil of an operating engine? I drew a sample from the SOS port of my 3406 genset using the Cat sample kit. It's basically a short basket-ball inflator needle with a clear tube attached to it that pokes into the sample port next to the oil filter. It had what I thought to be lot of bubbles. When the sample container was full, it developed a nice head of bubles on it for about a minute. It was another several minutes before all the extremely small bubbles had finished working their way to the top.
It had been running about 2 hours doing a live load test (Aprox 30% facility load) with load on it when the sample was taken.
The oil level in the engine is a hair under the shutdown full mark, and right in the middle of the Low-Idle operating range, so I don't think it's an over-full problem.
Using AMS Series 3000 5W30.
Doe anyone else see bubles in the oil when oil is pulled from sample ports of running engines?
