I bought a used set of 440-1 that came with a new set of Jesel paired rocker arms, what are you guys using them doing to oil them? Pushrod or spray bar or both Thanks in advance

Pushrod oiling with Isky Red Zone lifters. No bushings in block.

Spray bar here, no issues in 10 yrs.

It all depends on which block your using, or at least how its set up to oil the lifters.You can get inot fairly odd or expensive lifters if you need pushrod oiling in a block that isnt really set up for them.If its a race motor, the spray bars make it easy. Otherwise, the lifter oil holes in the block and lifter bodies will be a concern.Depends on how much you are willing to spend for lifters.

Spray Bars!

Different head but with the Jesel rockers on my B1m/c
heads I set it up for PR oiling.... the Jesel and
TD rockers were set up for PR oiling with the holes
in the rockers to direct the oil to the bearings...
just restrict the PR with a orifice

I think I have the best of both worlds. Spraybars for valve cooling, oil through the pushrods, with lifter oriface 90 degrees to the oil feed hole. A post by GOGREEN and another with a boosted motor talked about the need for PR oiling in high boost apps?

Pushrod oiling with Crane 904 offset roller lifters.

Pushrod oiling with Brian's (IMM) lifters that have the oiling holes in the lifter body offset to restrict oil.

Works good!

I use both. I've had problems when using just one way or the other. The spray bar oiling helps to cool the springs and to provide lube for the valve tip. The pushrod oiling makes sure that you get oil to the high pressure point at the pushrod ball.

Who makes the valve covers or do you make them yourself?

Indy makes the valve covers.

spray bars on mine too. The cooling effect on the springs must work because my valve springs last a lot longer than I thought they would with a big roller cam.

Spray Bars on my wedge Cab. I ran standard Indy Oiling then I had the heads CNC ported and had them milled for the jesel stand and system. I couldnt stand to pay $400+ for the oiling spray bar system, so I set out and made my own...
I ran this top end on a stock 499 short block, then built a real engine to put those on. Indy Maxx block...
I dont know how many pass's over a period of several years it had, but my stuff looked great. I know some have trouble, but I think the Jesel Cup on the adjuster, and ball end to ball end pushrods is the best.

Sorry for reviving a thread from the dead, but I'm trying to figure this out. I'm having to go to my "spare" motor due to a nitrous "incident"...

Megablock motor - I put on my 440-1's and Jesels. I have the spray bar setup from the other motor, but this motor was previously pushrod oiled, has 829's and hollow 7/16 pushrods. We fired it up, 100# of oil pressure cold (keith black pump) - about 70 warm, motor sounded great. I thought all was good...

Until I broke a Jesel shaft - the prevailing though behind the breakage is that in our hustle, we think we installed a shaft upside down (bolt recesses facing down) - at least I hope it was human error - we really don't know because it took out the shaft... Regardless, the result was a humungus drop in oil pressure to about 5# even though the lifters stayed in... Luckily it was at low engine speed - no bearing material.

Now I am paranoid, there is obviously not enough restriction in the oil feed to the lifters to prevent destruction should I have another valvetrain incident. Thoughts ??

On my mega block / 440-1 I have pushrod oiling via MRL lifters and hollow pushrods, PLUS the Indy head oil supply for the HS shaft rockers. I have 0.090 restriction in each cyl head oil feed line. Seems to be working OK so far but I do not know how the rocker roller tips get oiled.

Well I spoke with Jesel, they actually recommend going to pushrod oiling versus the spray bars. I guess my concern is really limited to just how much oil I'm getting up top - it's a bunch. !

This s JMO.. but I have played with a lot of TD rockers
but in a drag car I think the spray bar is a waste of oil.
if you run(lets say 9 sec)then the springs should be able to
handle the PR oiling that directs the oil to both sides of the
rocker to lube the rocker and the left over to do any spring
cooling... the single shaft oiling works very well but might
need a restriction in the supply to the shaft(basically if yo
have full time oiling you will) but the part time might want
just a little more slot in the bearing to add oil.. spray bars
by themself is asking for a shaft issue(lack of oil) and I dont
think I would ever run 2 systems to oil(either PR and spray
bars or shaft and PR and or spray bars)

I pushrod oil my paired T&D's on my -1's. The pushrod holes are big, over .100". The most oil pressure it could get was about 45 psi@7000. Ended up restricting my comp tappets. The holes were plugged with epoxy. Then the hole opposite the lifter bore orifice was drilled to .040". Been that way 2 years. Bearings look great (checked at 100 and 200 passes). It runs 65 psi @7100 with 5w30 royal purple. The adjustable pump relief screw is backed out about .250" from where it was before the tappets were restricted.
