New rebuild pushrod not spinning

-
In my experience, the camshaft itself is almost NEVER the issue. It's the lifter face machining. I've done posts on here in the part about it.
Yep, my cam from summit was perfect, and the lobs had a slight degree slant from one side to the other that could be seen with my eyes, that makes that lifter spin for sure. I have never had a cam shaft problem, totally agree.
 
i have a "rachet pump" prime all ny engines with it .... i take a pic tomorrow
 
It's very easy to prime a slant 6 without turning it over. Just get something to make a pressure tank out of and push it in the oil sender port with air pressure.
I knew there was a way and I knew you would know.

Something like this? Unscrew the nozzle and install a line

Yeah, that would do it! Might have to do it more than once to fill the system, but it would sure work.
2 quart capacity. Sold a lot of those to spray penetrating oil. I sold Howes Lubricant on the tool truck.
 
To prime a /6 on a new build -- how about leaving the rocker shaft loose / pushrods out until after you spin it over with no spark plugs in? Then there's no force on the lifter / cam lobe surface. Then once your oil pressure comes up, put the pushrods / rocker shaft in place, cold lash the valves a little loose, and start it up.
 
I use the ratchet pump
Tap into the oil pressure sensor
Can pump 4 or 5 quart in and spin the engine over by hand a couple of times while pumping
Do that for all my fresh engines
Works to find Internal oil leaks too
 
i jut hung a bag of oil up and let gravity do its thang. main thing is to get the bit from there and into the pump nice and full
turned the motor over small amount every now and again.

if you are using gloopy 20W50 its so damn thick that any air bubbles get crushed so small by the pump pressure that your bearings don't see a dry spell

would not risk it with 0w30 flows too easy, flow is quick and the pressure is lower, air bubble could be the length of the oil gallery and hardly get compressed as the oil at the other end piddles out of the bearings and lifter bores.
bearings will see a dry spell.
it only gets thick when it gets hot

I have a brand new Oregon Cams 2106 cam here, with new lifters and springs to match. Did Oregon grind these lifters or get them from somewhere else?
 
Im going to need a cam for my stock 69 340 build ....never thought would have to have it ground...just can't find anything that's good anymore
 
And still with all these warning about crap lifters.......folks instal them without checking.....& wonder why their lobes/lifters went south.

Oregon does reface lifters, if You have a question, You should be asking them not Us. If they supplied brand new lifters with the reground cam, I'd call & ask them if they are checking them, they have been a standup operation.....
