Need ideas on flushing 582 poly oil tank

[beeryboats]

My 582 went in for O/H today, so other things can progress. Any ideas on how to flush old nasty two stroke oil out of the poly oil tank on the firewall? And what is that little filter inline to the engine?

Still no ideas guys?

The little inline filter has a screen in it. That should be cleaned too. If you take it off the oil line you can see in the inlet and outlets to check it.

Not sure what to clean the tank out with. If it was mine I would take it off and clean it with turpentine or parts cleaning solvent.

Well... I'm not sure how the oil tank or the coolant overflow tank come off. Somehow the poly tanks are attached to the alum. mounts then through bolted to the firewall. I think.

My oil tank is held into an alumunum bracket by two stainless steel straps with thick cardboard shims. I was able to work out the shims and then work the tank out without removing the straps.

Make sure to check the tank carefully. The plasticizers in mine were long gone and the tank was very brittle. Fortunately it is a standard size Nalgene bottle and is easy to get a replacement. There are better choices than the original for replacing the overflow. I think AV8r3400 posted something about that a couple years back.

Thanks Paul. I should just replace the oil tank I guess. I did not recognize that oil bottle name though. Can you PM me more info?
Thanks,
