No oil coming up through my push rods.

I love it when people actually listen. Whether it's to me, or other good members giving good advice. These are the type threads that make the site worth while.

Unlike this trainwreck of a thread where the OP is as hard headed as concrete.

Why is my manifold vacuum so low?

Thanks for listening and answering questions, B717. It will only pay off in the long run.

You are welcome I thank you for always helping no matter what I ask. I know you guy's get a little perturbed sometime with us amateurs.

I tried to up load the right side and it won't and the rings around the push rods don't know either.

when you talk with the engine assembler, you might ask what oil gallery plugs he installed, and where. You might ask about lifter preload. Are all the pushrods spinning when the engine is idling? what kind of oil pressure does the engine run, hot or cold , at idle and cruise?

Go read that thread I posted. That's when I get perturbed. When people don't answer basic questions and then proceed to get butthurt. You actually listen and that's a good thing. Keep us posted.

Ok will do thanks again. my behind is going to bed got to play dad in the morning.
 
Ok but you know that there are a left and a right rocker arm for every cylinder, right? and 340 arms are different from 318s, right? and the difference is in the machining for the bigger 340 springs.

Go back to post #15, they sure look all messed up.
wait I figured out how to transfer the image here;

They look correct to me.
 
Are you running a zddp additive in the oil? Did the valvetrain noise start after an oil change? There is the chance that it wiped a lobe on the cam......

this is why I asked if the pushrods are spinning while the engine is running. If the lifters are spinning as they should, then so should the pushrods.
 
Have you ruled out an exhaust leak? Get a piece of hose and use it to listen around the header flange. Look for soot around the exhaust ports as well. I thought something was wrong with my valve train and it ended up being an exhaust leak. Second time I had a nice ticking noise, it was a mushroomed valve stem. It was noticeable without removing the rocker arm shaft. I would remove the shafts and inspect the valve stems real good for signs of wear. Maybe the stem height is incorrect. I attached a few pictures from the manual on the proper orientation of the shafts and rockers to help if you haven't already checked that. There's a notch in the shafts. Left shaft: faces forward and down. Right shaft: faces to the rear and down. It's easy to remove and reinstall those shafts and it'll give you piece of mind. Good luck.

An easy way to check if your lifters are spinning is to paint a dot (or silver Sharpie) on each pushrod and crank the engine over and make sure the pushrod is turning. If not, the lifter or cam lobe could be toast.
 
The last time I had oil squirting as high as the fenders, it was a roller-cam LA (with Magnum heads) that had its original direct-oiling (no metering) lifters installed combined with hollow pushrods. Would squirt right through the pushrod and through the Magnum-style rocker onto the fender, at idle.

I'd put a bet to it that you have a combination of AMC lifters from your rebuilder (with direct oil flow) and hollow pushrods. Combine that with the small hole on top of the LA rockers, and you've got a combination that will randomly shoot oil out of one rocker or another depending on the day - or however the engine farted crosswise that week.

My advice? Pull the rockers off one side and look at your pushrods. Hollow, I'd bet. If this is the case, replace all the hollow pushrods with solid rods of the same length. Problem should go away.

Why it didn't give trouble during Power Tour, I can't tell you. That engine I dealt with didn't give trouble until a week after I put it together.

I'll step off my soapbox now and let the experts take over again. RRR, your box.

With most lifters having oil holes these days, and most pushrods having oil holes these days, it is possible to have "oil-thru-pushrods" on a LA engine. It hurts nothing. However, that is not how the rocker arms get oiled. All the oil the rockers need should come from the shafts.
 
The stumper for me is it was running.

Now I'm wondering if a lobe or two went flat. Or some other wacky thing.

Not sure I agree that it can't damage things - in the case of my Magnum, the amount of oil that spewed out of the hollow lifter-pushrod-rocker seat combo was enough that the lifters couldn't pump up with enough oil to keep the valvetrain from loosening up and clattering. Something would have gotten fubar'ed if I kept it like that.

Had it been an LA top end with the same combination, it would probably have been a similar situation, if a bit less pronounced due to the smaller hole on the rocker.

what is the oil pressure? oil thru lifters and oil thru pushrods are not good for an LA engine=more oil up top-less oil to the rod bearings

If it lets the oil out uncontrolled from the rockers, yes.

But in theory, if the pressure is maintained, there shouldn't be a problem - after all, that's essentially what Chrysler did for the Magnum setup, except it took them a year or two to realize that they had to meter oil to the top end or it'd cause a low-pressure scenario at the top end.

Doesn't the oil just dead-end at the rocker/pushrod socket? Very little should come out there. Or I could be wrong.
 
Ok I talked with the shop owner that rebuilt my motor and he confirmed that no oil should be coming up through my push rods even if they are hollow. pretty much told me just about everything you guy's told me here last night. I took the rocker arm off and cleaned it and now I'm getting oil to all my rockers life is good except I'm still hearing a little ticking. I was told to put some sea foam in and let it run sometimes it will loosen up some carbon built up. what y'all think on sea foam?

Oil pressure is good on start up 40 when cruising and around 60 on start up. Oil in the car is Rotella T4 10w 30 with a zinc additive. I thank you Gent's for all I appreciate all your time to answer questions on this forum it really helps. To all the Mopar families in Houston my prayers go out for those in need as well as everyone else there.

God speed to all.

You get to check this yet?

seafoam? on a new build? I dunno, sounds like a Hail Mary to me. Are all the pushrods spinning when engine is running? That's important to know.
