All Small Six Help! Did I just screw up my new build?

[drag-200stang]

In light of the engine in first video being at 1000 and slowed down and seeing at real speed, I am not happy about the oil flow getting to the rocker tip. I do not have a solution right now. It may be fine, not 100 % sure it is. I am use to seeing more oil.

As high as the rpm was, booster fuel dribbling out may not be abnormal. Need to idle the engine down a good bit. Then there should not be booster fuel.

The throttle plates are completely closed with almost no airflow past the boosters.
There should be no fuel coming out of the boosters.
Also the two boosters are not acting the same even with the throttle plates open.
Something is not right with the carburetor.

From what I remember when I did mine, there are oil holes in the shaft and hole / grooves in the arms, you have to make sure they are lined up so oil can flow. I think the shaft is not reversible, there is a front and rear orientation to the shaft. I think others have even posted on this site that with the valve cover off, oil goes everywhere

@drag-200stang so I did what @awasson suggested and marked all pushrods. All were turning, except the 1st cylinder exhaust - the one that gave up. It turned at the beginning a bit, but then got stuck in one position.

@awasson i did try to tune it after I put the valve cover back, so PCV was hooked up to the opening on the cover. I did notice that if I squeeze PCV hose, rpm would drop. So I guess the leak should be somewhere there? Is it possible that PCV valve I’m using is the wrong one? Got it at RockAuto for my ‘66 engine.
And good call for some extra in cabin gauges!
Here is the same one I got from Summit. It might be for V8

@DON when I would open throttle - it would start splashing everywhere. Also, front cardboard was preventing the airflow from the fan. When I removed it to take a picture of the valves - then oil went everywhere.

@wme013 I didn’t run a drill bit, but I did clean passages with a needle

It’s very possible that the PCV valve is wrong. I bet most are made for a V8 application and then sold as good enough by the offshore manufacturers for all others.

I did clean the groves inside as well - ran it with angled pick.
Here is a pick of arm moved and you can see how it’s starting to form high and low spots and the the shaft oiling hole is right in the middle of the grove

It is possible that the lifter is turning and the rod is not, if the ball on the pushrod is oblong or damaged and keying to the oil slot in the rocker cup, Adjustable do not have that oil slot to get caught on. I have seen old engines, non adjustable that the pushrod ball has worn into the slot and quit turning, not a good thing but the lifters and cam where fine. Is it possible that the pushrod was turning and then got knocked out of the lifter cup and quit, does not seem likely. Your new rocker is it "new" or used? I also wonder if the ball on your pushrods are maybe a little larger or smaller than they should be and not fitting correctly.

I can try looking down the pushrod and see if I can see the lifter turning…
The rocker is NOS, so technically “new”. I left all same pushrods there. So that first one is the same one that broke off the rocker. I have some old pushrods, that I can swap and see if that helps.

I did pick up an adjustable rocker arm with pushrods, but didn’t have a chance to get to it yet - needs a lot of cleaning.
Btw, would you recommend something to soak the parts when rebuilding that adjustable rocker arm assembly?
With the one I have, machine shop did the most part of cleaning and then I disassembled and cleaned everything inside with brake cleaner

E85 works well as a solvent, cheaper than anything else.

I have not gotten a PCV valve lately that was not flowing too much air. These valves rarely fail. Using brakeclean spray with the engine running, I clean and reuse the old ones now. Overseas products are not trustworthy.

O'Reilly Auto Parts has new shafts for $53. The used one is probably well worn. Even if it isn't, it's worth $53 to avoid trying to get the inside of the old shaft clean.

I use gas as a degreaser as well, just remember the flammable part!! I have used mineral spirits as well and not quite as volatile, but doesn’t work quite as good either

 

[drag-200stang]

The problem with cleaning the rocker shaft and rockers is that is does not fix the wear issue and putting new parts with old worn parts and add more spring pressure, lift, is a recipe for failure. When the shaft and rocker wears into each other, it makes the inside oil grove smaller and slows down oil flow. My best easiest cheapest advice would be to send the adjustable in to be rebuilt. They will usually bore out the rockers and put in a bronze bushing type bearing that is more compatible with the steel shaft (check that they do) Steel on steel is a bad bearing surface.

A member on here used an adjustable PVC valve and had good results.

 

[DON]

I had an adjustable one. They are nice. Expensive but nice. You adjust them to your engine’s vacuum. One circuit for low speeds and one for higher speeds. You adjust them with a vacuum guage. They are rebuildable and have replaceable parts

Don, would you be able to find the part number for the adjustable?
I did order a different valve, but would be nice to have an option

 

[WillingnessLimp]

@drag-200stang as I understand, on adjustable rocker arm there is no oiling for the pushrods. I’m sure there are tons of people who used them with hydraulic lifters, but just wanna make sure that it’s not an issue. As mentioned before, with valve cover on and higher rpm, oil is splashing everywhere

 

[WillingnessLimp]

On a side note, I will try to figure out carburetor problem - I’ve noticed that I’m running through gas like crazy, with barely driving.

Could that also be an issue for so much carbon build up on the pistons? Running too rich and flooding the engine?

Yes. I'm quite concerned about that flooding barrel. Having that much liquid fuel running into the cylinders is going to wash down the cylinders and prevent the rings from seating correctly and fill the crank case with fuel. Check the oil and see if it smells of fuel and where the dip stick level is. Sometimes enough fuel can get past the rings and change the oil level but nonetheless, you don't want your oil thinned with fuel so if it does smell badly of fuel, I would change it.
