Dr. Lee, More Power, and Jamie Avant,

Do the archives hold a discussion of manual or electric lube oil pumps for pre-start of 6.2 or 6.5 diesels, especially for cold weather?
The idea is to pressurize and fill the lube passageways before turning the engine over.

Continental and Lycoming 4/6 cyl. opposed light aircraft engines can use TSO's electric pumps if one has too much money to burn. A manual
bottle-jack cylinder would seem to offer advantages over an electric pump.

Lee Swanger's "Electric Lift Pump and Racor Filter for the Early Diesels" solves the pre-start fuel pressurization issues, but not the cold start engine wear. Stationary power plant diesels use
pre-start lube pumps.

I am sorting out what I might want in the way of a
FedEx/USPS/FritoLay step van as a walk-around mobile engineering office.A guy in Portland,
Oregon, installed a captains chair and a 2-person
high-backed tour bus seat in a Frito Lay van. He pointed me to the Dieselpage. Lee's story about the 6.2 upgrade and the drive back to Florida focused my attention on the what Diesel Depot folks can do.

Comments from any of you would be welcome.

Hi Stanley,

My lone trip to Alaska was too long ago - August of 1982. Weather was fantastic then, no rain for a week, long warm sunny days - no hint of what was to come in three or four months.

There has been a meager discussion of prelube pumps. At "normal" temperatures, there seems to be no need for them - many members have driven 300,000 miles or more without them.

At the first or second rendezvous, Jim Bigley had an engine that had been out of the truck and drained for two years. We opened it up and found a full film of oil between the bearings and the crankshaft.

In my opinion, the most important thing is to use your block heater in cold weather, and perhaps add a glue-on oil pan heater as well. If you are away from 110VAC power, you might invest in the diesel-fuel powered ESPAR furnace that heats and circulates the cooling water.

Check out http://www.lubespecialist.com/espar1.htm for an offering from a Diesel Page Advertiser.

I know that out in the Alaskan bush, pilots will build a campfire under their engine to warm it up before trying to start it in REALLY COLD weather. Don't try this at home - for professionals and desparate amateurs only. So they believe that heat is more important than prelube when getting an engine going when your life and the lives of others depends on it.

Your office-in-a-van with a diesel engine sounds like a great practical project. Please send some pictures to More Power when it is complete, so we can all adminre (and copy) it.

Finally, I intend to keep my SAA engine "forever" and feel no need to add a pre-lube pump to Avant's fine engine.
