360 long block fresh build hyd lifters oil thru pushrods mag heads. I preoiled today & one rocker was flooding with oil & several rockers were getting a slight amt of oil but the rest of em were dry, WTH?. Does this sound like the lifters or pushrods are plugged or is this from the lifters being at different height? tho visually several of em at least appeared to be at the same height in the lifter bores as the one that was oiling profusely. Thank you for your time.

did you rotate the engine by hand as you were pre oiling?
my ladder of success is missing some rungs

No I wasn't turning the crank cuz I didn't think it was needed & I didn't wanna wipe the lobes. EDIT I could turn it if that is what I am missing then regoop the lobes. MORE EDIT Doc what special tool do you have? & Doc I am gonna put that motorhome 440 in the truck with the granny 4 sp/hyd clutch.

Try loosening the rocker shafts and try to pre-oil again.You should see oil coming out of the push rods if all is well

Since RR doesn;t say...
If it's an LA engine, you need to rotate it as you prelube.
IF is't a magnum engine rotating does nothing for you.
Since you allude to oiling thru the push rods, or at least expecting to see oil out of the push rods I assume it's a magnum? If so, don't bother rotating it as that is not relevant.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

It is mag heads with mag pedestal rockers/hollow pushrods (so full time oiling). I put a gauge on it to check the psi (80 so plenty there). I pulled a pair of rockers & no oil out the (2) pushrods. pulled the pushrods & no oil out the lifter tops. dropped in another spare identical rocker & lo & behold oil was gushing out of the lifter top so the lifters must be plugged up but they are new... so I undid one & it has a wafer thin round disc right under the lifter cup & the lifter cup will sit flat WO the disc in there so evidently these lifters even with the oiling hole in the lifter cup that the disc is placed there only to keep oil psi from bleeding off unneccessarily on a non pushrod oiling app so I think when I toss the discs all will be good. Thanks guys & Doc I had forgotten about the pilot hole potential but it is in my head now, thank you.

I got to thinking of another lifter I had apart aways back & the thin disc had some holes in it for a metered amt of oil & then it hit me that this one yesterday right after I tossed the disc is virtually FLOODING the rockers so that ain't right. I could order another set (& check that they are oil thru) OR I have a set that was broken in for I'd say 10 minutes (if that) on another cam (breakin aborted cuz of another type of oiling prob) that I could use if they are still useable on this new cam. I did butt two of em together & there is a significant amount of "rock" as opposed to both bottoms being flat (if that means anything). what do you guys think?

Hey Dog its been awhile. Here is where I am at: the lifter set that has maybe 10 minutes of run time on a prior eng & on the shelf HAS the plates with metered oil (I would love to toss these in if you guys think they are still OK on the bottom convex). the set in the eng now that precipitated this thread have metering plates with NO oil holes (they had no flow). I just now stopped by O'reillys on the way home & bought a single lifter (melling & I told the man 1975 dart with a 360) & I opened it up & its flat plate has NO holes (just like the ones in the eng now). PLEASE tell me I can use the 10 min run time set OR a brand/part # of some that are metered. EDIT I ain't tossed anything (yet).

You need lifters for an AMC.
Ask the local parts store for lifters for a 1974 AMC Javelin with a 360.

I called AZ & same thing, the same part #'s & they said they also have a pricier melling performance lifter 290114 (not sure if he assumed a JB in front of that # cuz he just got done mentioning the JB2011 in the conversation & he said they both in their pic show the top hole & I explained the inner hidden hole that is needed but he did all he could & I told him I appreciated his (good faith) effort. Are the (10 minute) used ones a no go??? If so I might just have to open em all up (32) & swap the flat metering plates (I can hardly wait!).
