Went to adjust lash & Crane Gold rockers !#&$ ( PICS)

Um idk the exact info for that cam but that seems like a pretty tight lash to me

If the harland sharps are roller bearing and the cranes weren't you need the hardened rocker shafts,

I am getting the full Harland Sharp rocker kit which comes with the hardened shafts.

also if your shafts are on backwards
you wont get oil to the lube them.
cheapst

Yep, that is a good point and this was the first thing that was checked and the shaft oiling holes were pointed in the correct direction as the damage to the inside on some of the rockers prove that the shaft was installed correctly.

I would think that you used a stock non hardened shaft to ruin the crane rockers, Do you have aluminum heads? That lash setting seems tight ,might be for iron heads, when hot with aluminum heads your lash would open up about .006-7, iron would not. What was you oil pressure before? If it was good ,don't worry about restricting the oil to the heads.

this may be a little off the wall, but I will share my stupidity to see if helps out another person.

I ran the crane golds and broke two of the shafts and couldnt figure out why. One broke while I was at the mopar nationals and we pulled the valve cover to see what had happened seen the shaft was broke again. I went and bought a set of harland sharps with all the mounting hardware and so on. Come to find out I was using to long of bolts. The bolts were bottoming out and the shaft wasnt secured inplace, just sort trapped in there.


Put on the harlands and never had it happen again, plus the HP gain.

Unless I'm missing something here I can't see how that is possible unless, like the old ersons, the cranes used a smaller than factory diameter shaft , the ersons came with a spacer that went around the shaft to make it fit properly though ...

just thinking out loud ...

but good thing to make note of and check .

Been there with you, black aluminum all over the place with new rockers and cam. Did it twice matter of fact cause I figured it was me, not the parts. Shafts shot, rockers shot. Came to the conclusion of not enough oil to the top end. Duh!

Now I assume you oil through the heads.

What I found was that the cam bearing had a misalignment with the oil holes in the block and maybe with the holes in that cam journal. The bottom hole is nice and wide, but the top holes are not. Gives you a misleading idea of how much room for error. it showed lots of oil while priming the oils system but not when running.

I pulled the cam, no damage. Did not want to mess with the cam bearing, so I chamfered the oil hole in the cam journal, increasing the "pulse width" of the oil shot going to the heads and rockers. Problem solved.

Change your oil a bunch o times to get rid of the Al fines.

I have crane golds, Eddie Heads, Hughes 242 solid cam.

Spin the motor till #8 ex valve is fully open , remove bolt from rocker shaft pedestal (pas side) & prime oil pump with a drill , you will know for sure if #4 cam bearing is'nt aligned.

Same goes for drivers side , spin motor till #7 ex valve is fully open (or there abouts) & prime with drill.

---

I'd only loosen that bolt so there is a gap between the bolt and the holddown and not remove it , when you spin the pump a stream of oil will be hitting the hood and covering the engine compartment.

If the garage roof is high enough you can catch it on the way down.

Just a couple of questions,
#1 does the motor have head studs? If so im sure the the stud itself is to big(1/2") and cutting off oil flow to the rockers..DAMHIK..the stock bolt is under cut to give room for the oil to pass and get oil to the rockers. Running the stud cut oil flow almost 80% over the stock bolt.
#2 Did you have the shafts on the right way, there is a front and a rear for the oil holes to line up...
#3 Are the effected rockers from the front or rear of the motor?
#4 Nice looking place you got there

---

1) No head studs

2) I didnt know there was a front and rear....I just thought that the rocker shaft oil holes should be facing down toward the head?

3) All the rockers on the driver side head had some damage ( I havent pulled the passenger side yet).

4)Thanks been in the new house for just over a year.

I think he was talking about rocker studs since the oil passage does not intersect a head bolt hole . you have bolts from the pic above , no issue there .

You have alot of open spring pressure for an unbushed rocker , but you need to confirm oil flow . I wouldn't do it bumping over the engine though , pull the dist. and run the pump by hand , be prepared for a mess .

Me , I would take an old junk steel cover , cut off the top , put the rocker shaft and rockers back on and see how much oil oozes out of the assembly once you get the cam in the right spot for the hit or miss oiling , using this method you could do it with the starter , deactivate the coil .

Hey John, Maybe you can school me on something here.
I keep hearing about the hit an miss oiling to the rockers? THe rocker shaft and rockers are fed oil from the oil galley which runs up from the lifter valley correct? Well those galleys in the lifter area lead directly back to the oil pump...Now how is that hit and miss when the pump is running and forcing oil through the lifter galleys up to the heads,rockers and lifters?

The oil for the rockers is coming from the #4 cam bearing. If the bearing hole isn't lined up with the galley or the feeds from the cam to the heads have a restriction of some kind then your oiling could be compromised.

Johnhaha ... where in this or any other part of my reply do you see the word "dolt" ?

---

Stanton, You didn't use the word "Dolt"


But you did State"

"WOW... you're this deep into playing with a motor and you don't know how the oil system works!?!

I think you're the root of all your problems."

That's pretty harsh IMO. You could of more easily and nicely answered the question like Johnhaha did instead of just stomping and pounding on the guy.

The energy/text spent would of been the same. One positive vs one negative.
