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

This is what I had:

@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

There is oiling for the pushrod on adj. rockers, it comes out of the rocker at the adjustment screw/ball and flows down the screw/ball to the pushrod cup, over and down the push rod. No issue for hyd. lifters.

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

That’s a very nice piece! And you are right, a bit pricey lol
If the one I’ve ordered is not gonna work out, this will be my next step, thanks for the link!

I'm using that one you linked from Summit: ACDelco Gold PCV Valves 19310788. It seems to work as well as the ancient one that was on mine originally. My old one was probably fine and rattled when I shook it but for less than $5 I thought it would be silly not to put it on the new engine. I've tried it with both and there is no noticeable difference.

For the sake of interest, as a test, I might put a breather on my catch can block the vacuum port on the log to see if there is any difference in how it idles and runs. It'll have to wait for some nicer weather around here though. Probably a few more weeks.

That’s good. Amazon says it fits the I6 but doesn’t fit the 390. It’s not a generic one

I’m still in limbo with my engine: trying to figure out carb situation and what to do with the rocker arm.
In the meantime I picked up an adjustable rocker arm assembly and going to clean and rebuild it with tips from Falcon Performance handbook.
I guess I got couple questions for you guys:
1. Why do people get a used adjustable rocker arm assembly? I was searching for some replacement parts and you pretty much can just assemble the rocker arm with NOS parts… even for a rebuild from rocker arms unlimited it’s about $350. Getting all new parts will possibly be cheaper? That’s just a side note.
2. I noticed that the assembly I picked up doesn’t have a stand with flow for extra oil, like I had on mine. How necessary is that? Should I just swap out one from mine or keep it as it is?
3. Push rods. Some of the ones I picked up are slightly bent, so I’m thinking of a new set (or just replace the ones that bent). RockAuto gives me 2 options:
- SBI 1901280 (8 inches long)
- Melling MPR 81 (7.85 inches long)
Any suggestions on these ones?

Thanks, Tim

1) Are you asking why people don’t rebuild the non adjustable one with adjustable rocker arms and the cup/ball pushrods? The reason I assume is cost and availability. it seems the only OEM adjustable rocker arms are available at Rocker Arms Unlimited (RAU) unless you choose to buy the Australian Yella Terra aftermarket ones (comes with pushrods and lifters). Personally, I was planning to go the Yella Terra route but I was able to secure a rebuilt adjustable assembly with ball/cup pushrods, some spare parts and with the mod to the rearmost rocker shaft support for better oil flow to the rocker shaft for a fraction of the cost of a Yella Terra set or from RAU. I checked all of the usual suspects (Rock Auto, Clifford, Classic Inlines, etc…) for OEM adjustable arms and nobody appears to have NOS. I didn’t call RAU to check if they had stock.

2) I’m not sure how critical that piece (the stand with flow for extra oil) is. Hopefully someone knowledgeable can pipe in.

3) I have read that you get better geometry with the longer pushrods; @clochard68 mentioned it in a discussion about a head and adjustable pushrods a while back. More info and a link to his source here: https://fordsix.com/threads/winter-...ing-with-a-large-log.90134/page-3#post-731757

Looking forward to hearing about your successful conclusion.
