Re: [MV] M35 oil pressure at startup

What you have described is a normal situation, but also the very reason not to race the engine until pressure comes up, ESPECIALLY a turbo charged engine.

The operators manual, at least the early multifuel manuals, advise that when starting the engine, pull the engine stop handle out, and revolve the engine (It can't start in this state). The stated reason is to check for hydrostatic lock. However, I can't help but think that the starter motor spinning the engine and operating the oil pump would help alleviate some of the dry bearing/cylinder condition. And of course this starter is much slower than the idle speed of the engine. And yes, cranking the engine like this does move the oil pressure gauge.

This is not a reflection of anyone on this list, but it seems to me that the advances in automobile manufacture is such that today's vehicles do much of the thinking for the operator (Indeed, they are so sophisticated they HAVE to do the thinking, 'cause I certainly don't understand/can't diagnose/fix one, nor can many dealers without expense test equipment). The multifuel deuce is late fifties/early sixties technology, regardless of built date. And even then it was an update of a 1949 design.

The manuals have evolved much like the auto industry. The earliest are written along the line of....."if this n such breaks, here's how you fix it" to today's "if this n such breaks, call direct support." The vehicle has not changed, but the manual, and what is expected of the operator has.

It seems to me that today's civilian car manuals have very little truly useful information in them (other than how to set the radio :)), the auto itself tells or does everything for you from a reminder to change your oil to turning on the headlights. You are unlikely to be able to go to your local new car dealer and find a car that will let you do anything to it that will hurt you or it. Can you even put a new car in gear without your foot on the brake pedal? So, society has quit looking at the manuals, not much info needed or useful contained in them.....

The deuce is not that way, even though the later operators manuals are written to lead you to believe that. I suggest all deuce owners, or potential owners, purchase and read as many of the manuals you can find. What is downloadable from LOGSA is nice, but not nearly as useful as the older TM9-8022 and TM9-2320-209-10. The former was written before the Multifuel engine was produced, but the body, driveline and chassis are essentially the same.
