hi,
re
"I am thinking of a small electric auxiliary oil pump for this, so that
I don't need to interfere engines own oil circulation at all."
you could do this, but there is no need to re-invent the wheel.
Bypass oil filters have been around a long, LONG time.
The starndard procedure is to just tap off the engine oil pressure
somewhere.......and run that oil......which bypasses the main oil pathways,
and fitler that small portion of oil, and then return it to the sump.
I'd like to see a japanese diesel engine with two oil filters on it.
I'm skeptical that such and engine exists - a car or small truck diesel with
two main oil filters on it.
Glad to be enlgihtened though !
Given that most road vehicles have wet sump engines, how could one have an
'after' oil pump ........say to filter the oil afer it has gone to the
bearings ?
With a dry sump .....yes. Perhaps that's what you have.
