Hi Michel

I went back to look at your diagram...... are you saying you have an external oil line that runs from the front of the engine,,,,, somewhere behind the big generator.....???

I have never seen that before...... not typical of any Dodge flat head whether it is a 207, 230, 251 or 265.......

Do you have a digital picture of the set up.......must go back to check some books....

This is the picture!
i think this may be the problem i also have a 237 in a welder and has the same problem!

I was wondering if the engine bearings and pistons are the same on a
251 1967 wm300 power wagon

Was just talking to one of the guys in our MV club who is a old line Dodge Nut. Was asking him what he saw on his M37 as oil pressure. Read him a couple of the posts.

He had two good questions:

Have you dropped the pan yet to see if you have sludge? I could not remember if you said the engine had been apart. His thought was if the screen is picking up a sludge this could cause the fluctuations.

His second thought about the fluctuations was is it the correct filter and is it in new?

All this from a guy who is talking on his phone stuck in a traffic jam in Boston.

Try pulling your oil pressure bypass valve out. Make sure it moves freely in its bore, and that the spring is not broken or catching.
I am not familiar with this model, but the pressure characteristics indicate excessive clearances. If you tear it down, don't overlook the cam bearings.

[Michel D]

No sludge in the pan and the bypass valve is ok.
i have taken the oil pan off to see if there is someting loose.
The connecting rod are ok!
