Are there different length tubes avail for the slant engine. When the engine re-builder assembled my engine he did not remove the tube from my old pump and place it on my new one and of course threw out my old parts so I had to source one from a spare 1984 engine I have laying around.

Is there a tube that I should be looking for that might be a better part to have on my engine or where they all pretty much identical?

You should always ask for your old stuff/parts to be returned prior to work being carried out.......for just this reason ^^^^^^^^^^^^^^^^^.
Ya just never know.
 
I have only seen 2,, the long tube that is on the older pumps , the newer pumps are short,actually not a tube at all. I'm sure there is a reason for the tube, also why they did away with it when they changed the design for the newer pumps. Which is better??,, I have no Idea. I'm sure someone that knows will chime in and tell us.
 
A machine shop did that to me once. I delivered the head on my 69 slant with the rockers still on (didn't know, didn't tell me), then got a bare head w/ just valves back. I asked for the other parts and he looked around and found a cardboard box with most parts, but missing the special bolts and washers, then just shrugged. I had to go to a junkyard to get what they lost. I learned early not to pay big money to people who just pick their nose in front of you. Today, Angie's List and Yelp helps un-employ them, as they deserve. Worse is when a shop cops attitude for their screw-ups because you have "an old car", "six cylinder", "not a Chevy SB", or such.

Well put! I cant get no respect cause it a slant six, the guy that did the machine work typically does high performance Ford and Chevy.

I dont care, I like the slant and am not going to follow the heard.

My fault, I should have used another shop that was about the same price but a bit further away. I could have walked to the shop that did the work and at the time that seemed important to me.
 
i didn't see it so here is goes

The older tubes were longer, so they would hold more oil in the filter so startup had pressure faster AND they also had a one way valve in the tube to try to keep the filter full. On the newer shorter ones they dont have the valve.

i always use the longer ones
 
Uh oh, been noticing that the oil pressure is a lot slower coming up than it was before oil & filter replacement. Possible for this tube to have come out stuck in the filter? I was hoping that it wasn't a feature that the dreaded Fram had that the Wix does not.

Anyone got a pic of either or preferably both tubes?

I asked on the slant forum and someone posted this picture and said this.......Long "standpipe" for tall oil filters & short tubes for short filters and no check valve & tube for oil filters with built-in check valve & tubes.


I asked for clarification about the valve deal but havent seen any response. I have the long tube but have no idea where this valve is supposed to be.

I have read at one point that the valve is in the filter now that I think about it, I think I have read only the high quality filters have the valve. Ill keep asking around, surely someone can give more info.

the tube screws into the oil pump housing and has the threads for the oil filter. IF it were to come out you would have nothing to screw the new oil filter to.
 

I'm pondering silver-brazing an appropriately sized tube to the fitting screwed into the oil pump. Unless it physically interfered with any anti drain-back valve in a filter I don't see a problem with having it.

What's curious is what this says about the Carquest branded Wix filter vs. the Fram that the PO installed.
 
ive run K&N, Wix 51515 or is it 15151? and PH8A filters with both long/valve and short/ w/o valve and no change
 
Hum. Occurs to me that with the remote mounted OPS that I could be seeing how long it takes to 'bleed' the tube of air. I'll try purging it of air and see it that has an effect.
