1978 Dodge Motorhome with 440 engine

I have a 1978 Dodge 24' motorhome and has been parked over the winter. When I started a couple days ago there was no oil pressure. I checked the sending unit and pulled it and cranked engine over and have no oil there at all. I was told that this motor has external oil pump and was wondering where it might be located?

    look at the motor mounts


I talked to a local mechanic and he thought it had lost it's prime. The oil pump was on the outside of lower block on drivers side. I took it off and he suggested packing as full as you could with lithium grease and tting back together. I did this and it worked.

It can be on the oil, and a lot of times on the batteries too

Dodge 440 motorhome parked now won't start crank over. Battery is fully charged changed ballast res. Tested coil.Changed ecuand voltage regulator. Repaired damaged wires, cleaned conn. Any ideas?

if you're getting all those things then there can only be one problem left, in order for it to start it has to get gas, so my guess is the gas pump is not working. btw are you getting the check engine light? if so then check the gas pump.

i have seen this problem on many dodge motorhomes , does the air cleaner have the electric device on it? if it does i suggest reverting the engine back to the old style distributor that does not require it as those tend to go out and cause a lot of problems,it is a fairly easy solution if you are mechanicaly inclined and you wont see many problems with the electrical system of the engine afterwards.the hardest part of this solution is finding 1 of the older style distributors

I have a 1978 dodge 440 in a motorhome and the engine turns over but as soon as I let off the starter it dies. It seems like its not getting power to the engine?

It could be many things so start with the easiest /cheaper first.Check your plugs , they will tell allot...white= too lean .black and/or wet =too rich .. clean and gap If your coil is old and not sparking hot enough it will sputter and stall . If your ground to the ignition is loose or corroded , same result. If the motor has noit been run for a long time ; replace spoark plug wires , coil , pioints, rotor , cap ( just replace the distributor with electronic etc.) . Put in fresh fuel (gas goes bad) and filter.You might run some carb cleaner or rebuild the carb , your start /idle jets might be plugged.Check all vacume conections , cracked or loose hose equals too lean to run when cold. If all else fails loosen the distributor and swivel small increments back and forth until it lights. Oh yeah , if your alternator is not putting out the motor will kinda start then die beause the battery cannot keep up.
Good luck

Hi, do you have the smog diagram for a 1973-440 motorhome.? thank you

73 was an awful year for smog devices.
You could just look at any 1973 Dodge diagram, because a motorhome is no different.
But my advice is to take all smog stuff off. It did not work well in 73, and harms engine. You don't have to test anyway.
