Good to know for sure.

 

Ok back to the stock filter. Still gettin dry starts. Cruiser please give me some insight

 

What brand?

 

Wix. When I took the higher capacity filter off the adbv was working flawlessly. Now I'm stumped. I never used to get dry starts now all of a sudden I get em quite often. Oil pressurize stays at 0 for a second or two then pops up to about 50.

 

Sticking relief valve in the oil pump? Any noises?

 

Dry start noises. And I have a bearing noise kinda like a water pump. Water pumps good..

 

So 2 different noises?

A clattering on start-up til pressure builds?
After that, a grumbling noise like a worn water pump?

 

Besides breaking a water pipe and flooding my shop ( in construction), with the shutoff 150 feet away, & prepping the garden beds, I'm roughing out an electric/solar water pump system to fill my tank up on the tower.

The prime on the pump here turns out to be a little more tricky that I'm accustomed to. Longer story short, on this, a surprisingly small amount of air will ether prevent it from priming, or once it managed to run but pumped at a sower rate, (and stayed that way), until I primed it better.

U runnen' some uncommonly thin oil? I'm not familiar with how the pick-up tube seals to the pump. O ring in a vacuum? Gasket? Just a thought. Going FROM nothing to full bore is what a pump does when it primes.

Sorry Btw....maybe you should put some real oil in there till you figure it out.

Another thought along the same line....if the pump is a bit worn, could it depend more on residual oil left from last start to move that air out and prime?

 

U got it. The noise is more of a tinny rattle then a grumble now that I listen again.

 

I have been using this one as well, seems fine.

 

I wonder if you've got a lifter or two bleeding down.

 

That cause the oil pressurize to stay down while they fill back up?

 

Yep, they do.

 

I'm gonna replace the pan gaskrt, rear main and oil pump and lifters. Re ring?

 

I'd certainly have a peek at the bearings. Could replace them. The thing is the cam bearings could be worn and you can't see them. You don't want this to turn into a rebuild, do you?

Weren't you leaning toward the slow build of oil pressure being lifters?
