[C320-list] Perkins oil change

[Gary Magnuson]

I just replaced the oil on my Perkins M30, hull 205.   I have one of 
those vacuum cans with the small plastic tubing that gets inserted in 
the dipstick tube.  My engine also has an extension tube from low on the 
starboard side of the oil pan with a small plug on the end.  I get tired 
of pulling the vacuum handle as the oil slowly gets sucked up this tiny 
plastic tube, so I assembled a combination of plastic pipe fittings 
coupled with a sump pump check valve that wedge into the vacuum can hole 
where the pump handle tread's on.   The end of the check valve is about 
the same diameter as my small shop vac hose, so I simply use my shop vac 
to supply the suction while i insert and withdraw the suction hose to 
recover the bulk of the oil.   Be sure the engine is up to operating 
temperature before starting the process since the hot oil flows much 
easier.  You should be able to recover a full gallon after you add the 
oil from the filter into your can.

I hope you can visualize ok.
