B engine oil pressure?

the pump pushes oil thru the cam shaft lubes the crank and rods......... at the same time 15% of the oil goes thru the filter and is drained back to sump.. Take the filter off and see if it is packed full of a cotton material... see that there is a 1/4 inch diameter steel tube up the center of the filter... see that the tube has a very small hole in the end to bleed oil into the filter...... if the filter is bad, the tube is gone, or the hole is oversize, you can leak off 40% of the oil flow to sump and have no pressure inside the motor to bearings........ You could also have worn out bearings inside on the crank or cam that are causing loss of pressure................. pull the filter and tell us what you see.

Filter isn't great but didnt want to put a new filter on a trash engine

actually Got ahold of NAPA wgo sent an engineer out. I showed them what was happening using my old filter and their new filter. The engineer then installed a 2nd new NAPA with same results. In meantime I had purchased a new filter from Steve at B&B, {actually six, he had em on sale},anyway, he tried to convince me it was OK and would cause no problem. I said if he were to put that in writing and guarantee in writing they would rebuild or replace engine if I ran it that way and engine blew, I would run his oil filter. He could not do it. Took all information and went home. I even provided him my new old oil filter I refused to use, along with my old original filter. It took a couple months but NAPA contacted me and thanked me for the help. They reverted back to the original style filter and even paid me back for the original filter I had purchased. All the old new style filters they had made were supposed to be returned by dealers and the good ones replaced them. Some dealers weren't very consciensious so sme escaped the recall. Looks like you got one of them.

Read BOBS post........... you have a JUNK FILTER.... It will not work... PLug the stand tube as Dick said and see if that helps or you have additional problems.

Sounds like NAPA did not destroy the bad filters from a few years ago and came across them in the warehouse and said what the heck lets see if we can sell them. Leon

    Hey Dick L,,,,since you mentioned the groove on the rocker arm stand next to gas tank,,,it got me to wonderin bout something,,,,, Is there susspossed to be similar situation (groove) on the D14 149 engines,,,?? If I remember right,,mine had studs in head with washers and nuts on the 4 stands,,,but don't remember a groove,,,,???
 This engine has never had much oil goin to rocker arms,,but I guess just enough to keep em from siezing,,,???
 

You need the cotton style filter. Think about what's going on like this. You're standing in the shower and your wife turns the water on in the sink. Notice how the water pressure drops? That's what's going on with that paper filter you have. It allows too much flow so the pressure is reduced to the point you're not getting flow to the rockers. The cotton filter doesn't allow oil flow through it as easily as the paper does. More resistance to flow means more pressure.

Ok, put a correct filter on it (fram) and cranked it. No oil pressure on the gauge. Took filter back off, cranked again to see if oil if pumping. Oil does come out of tube well. Took rocker assembly off and like off on side of head. Blew air through it well.. Now what?

I think I got it now.

You could have lost prime which requires you to shoot oil from oil can down the oil pump exit tube.  If that solves it watch it and if it happens again you will meed to fix it. The cause will be the check valve (ball) in the rotor of the oil pump. Speaking from experience,

What Gary said.......I noticed the color in the picture right away!  Not a good thing.

So what did you do to get oil pressure? Just running time?
