Hemi valvetrain oilsystem

Im new to Hemis and im beginning to be very confused aboute the oiling system for the rockers on oure Veney heads. It has extarnal oil lines that feeds the intake rocker shaft and out to the intake rockers so thats no problem but were is the oil feeding to the exhaust rocker shaft

Have checked the stands and 2 of the bolts have cut oilpassages but there is no feed hole under any of the exhaust shaft stands or in the bolt holes

 

it will not need to be fed oil. ex rockers will be ok with no oil fed to em. i just pre oil before you start.

 

what we have done and seen others do is drill a hole in the shaft [exhuast shafts only] facing up, between the rockers, just large enough to fit the end of a pointed oil pump can and pump the shaft full of oil before each run. We did it this way for years and never had aproblem.

 

OK, thats sounds like a good idea but i still dont get it, I dont need oiling to the exhaust shaft but why is rockers and rockershaft prepered for that?

Setup is
Intake Stage V rockers, they are drilled for oiling the adjuster/pushrod, there is no oiling to the spring/roller tip side. The intake shaft is drilled for oiling one side of the rockers and are extarnally oil feed.

Exhaust is ? (black non rollers), they are Drilled out to the pushrod/adjuster threads and they are also drilled for oiling the rocker tip/spring, exhaust shaft is prepered (drilled and slotted) so it could oil bothe sides of the rocker.

So there seems to be a plan for alot of oiling in the valvetrain but more than 1/2 of it arent used? and the engine had 2 burnt pushrods when i bought it.

Its winter here so i have 4months beafore it should be ready so i dont mind to spend some extra time on it now, infact better now insted of shifiting pushrods at the track.

What aboute drilling a hole and put i an AN4 for estarnal oil feed to the exhaust shaft stands exactly like its done on the intake side?
Is there any risks widh it? Lack of oil to the rest of the engine? (system 1 pump dry sump) Or to much oil up on the heads (if thats possible)

Sorry to jump in, why not on the intake?
Would putting a grease nipple in one end then fill with grease be ok?
I have a jp1
would i need to block of the oil feeds to the cylinder heads?
Thanks and sorry for jumping in but i have wondered the same
thanks

 

I know your going to get a lot of opinions on this, but here goes, sounds like you may have stock exhaust rocker arms and shafts, thats why they are drilled and grooved. The exhaust rockers have less ratio, so they don`t see the stress that the intake side sees. I would guess the two burnt pushrods were intakes? Most of the time I have seen pushrods burnt on the warmup, due to poor prelube of the pushrod cups/adjusters and lashcaps. We had same head setup external oilers only on the intakes, drilled exhaust shafts, filled with oil, our prelube ritual was as follows; put a glob of black moly grease in each pushrod cup, adjust valves, squirt torco assy lube on adjusters and lash caps. After every run, adjust valves, torco on adjusters and lash caps, fill exhaust rockers, 10,000 RPM, no problems. As for your question on presrure oiling the exhaust, I wouln`t do it, you may be taking oil from somewhere more critical. Sorry for the long post, Tom.

 

Dont be sorry, Longer posts that explaines why and why not i should do things are really apriciated

It was 1 exhaust and 1 intake pushrod that was burnt http://home.koping.net/u3243a/tillfalliga/hemi/DSC01202.JPG
Are stock exhaust rockers OK or should i upgrade? Im not planning to rev higher than max 9500 properbly not over 9000 most of the times.

 

Only my opinion here, stock rockers are fine for what you are doing.

 

OK, thanks

Any more opinions about pressure oiling the exhaust rockers ( tru an orifice)

 

I have Veney heads w/ pressurized intake rockers and nothing on the exhaust. The only thing we do is on initial fireup (first of the day) is use the techline black goo on the pushrod cup, never touch them again (except for checking lash) until the next day we have about 400 lbs of seat pressure and 9200 rpm we burnt one pushrod cup all year long, I suspect someone missed getting the goo on that one

 

OK thats maby right (ill hope so) but whats "techline black goo" Theris a lot of chemical stuff that we dont have here in sweden, is it some kind of highpressure lube?

 

A lot of people also have good luck with the Torco ep lube

I've used the torco stuff with good results as well.

Noel Manton can sell you the techline stuff, he's a sponsor on here.

this is the guy that setup the techlinecoatingswebstore. My true job is "shipping clerk". but in my spare time I like to play with HTML. but I realy not have lot of time on the webstore. However I did a google search an found that you had some trouble navigating the site. I am not the best graphics designer. But I listen. I Agree with you, that the website does need alot of work. If you have any hints. Can let me know. Just a hint to navigate the site that I found. is enter the item in the search field.
