Bought a Van......

Actually I think in that situation they just had push rods that were too small.. probably tried to make something they had work or ordered the wrong ones or the wrong size... The adjusters were or are a little too far out for my liking.. I can only imagine how far they were without those little caps..

I don't know about the caps, but I have Harland Sharpe rollers on my '01 Ram. I think Harland Sharpe is amoung the tops when it comes to fitment and quality

Ohhh Boy now you did it. That one guy is going to come in and say rockers with roller bearing are junk. Lol.

Ok, as good as this runs, I discovered something. I tuned my ear, even drove it with the dog house off, I hear at the top of the valve covers something that just didn't seem normal. The guy I bought it from gave me new Comp Cam push rod guides with it and said on his trip to Florida, one cracked. So, I pull the drivers valve cover and it has Comp Cam roller rockers, mounted on adapting stud mounts to 3/8. Some of the rollers were half off the valves. I rotated the engine till valves were shut and some of the rockers were so lose I could almost pull the roller off the valves. No adjuster at the push rod, but I could tighten the nut that holds the rocker and take the slack out, but not before it was solid on the push rod and valve. I'm pulling them off and putting original magnum rockers and plates on.

Got all the rockers swapped out. Started it and let it idle, and as good as it ran before it seems even a little smooth and quiet (again, my ears are on high alert! LOL). I pulled a plug. As I thought, it had the iridium plugs in it, and black as coal as I suspected. Going to buy RC12YC's now. Solid copper core for me!!

THE TUNING CONTINUES..... (jabs?) LOL :D

My comment on measuring the distance from the valve stem to the rocker arm stud is in relationship to had the guy drilled the heads for the bigger studs he might have drilled them off center of the original hole in the head. Thus moving the rocker arm forward or backward or sideways in relationship to the tip of the valve.

no, he used adapting rocker arm studs (COMP Cam).

The tuning continues
 
still seems to sound a little like a few plastic BB's in the valve covers. The factory rockers fit well, don't really know what it is at the present. :realcrazy:

Worry not. It will let you know when it's ready to fail althou you may not be ready.

Merry Christmas.

The troubleshooting continues.

I gave it a few "pedal to the metal" exercises today.. :D :D

The Tuning Continues.....
 
The valve train noise in the valve covers continues on start up. As sloppy as the roller rockers fit vs the factory rockers I replaced them with, I thought that would cure it. Now I'm wondering about push rod length or the roller lifters used. On a side note, my '01 Ram with a 5.9 has ZERO noise at cold start up in any temp, and it's at over 270,*** miles.

Hang the motor out and stab the 360 out of your Duster in it. Then put a big block in the Duster.

LOL.... I think the magnum is a good engine in there, I'm just not a fan of COMP Cam anything in valve train. I bet it's got Comp cam lifters, pushrods, and between the two lies the problem. I can pop the intake off and put different lifters in, measure the push rods and if they are not kosher, put the pushrods from my 5.2 mag in there. On side note, one complaint about comp cams is there noisy valve trains which don't seem to hurt anything.....
 
Changed oil in it today. Not sure what he used, but it had a NAPA gold filter. Every vehicle I buy gets a fresh oil/filter change just so I know. Then went for a nice little ride :) Another nice day we had indeed..... and the rain yesterday washed a lot of the salt off the roads.
 
Here you go.

THANK YOU!!!! This HAS to be it. Some of my pushrods were scraping the guide plates. It wasn't making sense when I studied it. Oh, you inbox is full or something?

That is a complete kit that Crane sells. Here it is.

Crane Rocker Arm Guideplate Conversion Kits 36655-16

It almost looks like some of yours is missing, OR it's something someone has cobbled. It's a nice kit. I've used it several times and have it right now on the 5.0 Explorer engine I built for RobKat. It works good and should not allow the rockers to move off the stems at all.
 
When you change to rocker studs in the Magnum, it MUST have guide plates to keep the rockers from twisting and coming off the valve stems. I didn't see a good picture of what you HAVE, but that Crane kit I linked to on Summit is what you NEED.

RRR, he had the Comp Cams conversion guideplates which have the spacing WRONG for the pushrod slots.

Yes, it had the guide plates, but a couple of the push rods were scrapping it. Comp Cams admitted they had a bunch of "wrong" plates out there and sent him a new box. I didn't install them because the rockers "rocked" all over. I think the same roller rocker used on GM's is the same rollers they give for Mopars???? It's non-adjustable but does "adjust" by the center nut. Anyways, I installed the factory magnum rockers/guide plates I happen to have which fit snug as a bug in a rug.
