Valve train clatter

Post #1 by charliecurrie » Sat Jun 08, 2019 9:08 am

Just installed 264/274 112 cam from Vintage Inlines and I can't get the valve/rocker adjustment correct - quiet.

Stock '66 200.
Rebuilt '66 head
Adjustable rocker assembly
302 valve springs
New Sealed Power hydraulic lifters
Stock pushrods - ~8"


If I adjust the valves according to the CI tech recommendation the valves hang open.

If I back the adjustment off until I get maximum vacuum and smooth idle, it clacks and taps annoyingly loud.

Suggestions?

I can't get close to zero lash without the valves hanging open. It creates a huge vacuum leak and uneven / surging idle.

If they're not clacking / ticking they're not closing.

When everything is lose and noisy, I have 20+ in of vacuum and a rock steady needle on the gauge and a rock steady idle at 500 rpm in neutral.

My rockers are the shaft mounted non-roller. This valve train worked fine with the stock 53 year old cam and lifters. Well fine for its age and worn lobe the fuel pump lever rides on and a couple of lazy lifters.

Have you tried to isolate the problem to a single valve/lifter? Do all the lifters depress?

It's every cylinder, every valve...so, I suppose, every lifter.

Is it possible none of the lifters are depressing? Although, my buddy who helped with the install, depressed one of them for no reason before I put it in.

What are you using for springs? What is the closed pressure?

302 - 71 lbs

Started with stock 200 springs. The 302 springs didn't change anything.

How is your oil pressure???
Your valve springs are not involved with this condition, but you need close to 100# seat pressure.
Sometimes it takes several minutes to have the hydraulic lifters to respond to a half turn of adjustment from zero adjustment.

Oil pressure is good - no gauge - but the light doesn't come on. And, there's plenty of oil flow to the valve train - easy to see with the valve cover off.

Oh, we've run it longer than several minutes and the valves never close completely. But, as soon as you start backing off the adjusters you can see - vacuum gauge and tac - and hear and feel the improvement. We do the adjustment with the engine running.

All I changed was the cam, lifters, valve springs and timing set. Didn't have this problem before the change.

It runs down the road just fine. A noticeable improvement. Idles smooth at 500 rpm in gear.

Take each cylinder one at a time starting with #1
Turn the crank clockwise until the EXHAUST valve just begins to open and stop. Then adjust the INTAKE valve with 1/2 turn past zero lash.

Now turn the crank clockwise again till the INTAKE valve opens and begins to close. Just as the intake valve closes stop and adjust the EXHAUST valve with 1/2 turn past zero lash.

Continue the process on remaining cylinders 2,3,4,5 and 6

Zero lash is when you no longer have rocker movement by hand and you can feel the pushrod starting to press down on the lifter plunger.

This is a wild guess, but is it possible all the lifter plungers are bottomed out & the lifter plunger has not pumped up to the snap ring.
Take the rocker arm assy off the head.
Remove the distributor & with a drill spin the oil pump shaft to get line pressure. That will get the plungers to the top of travel.
Reinstall rockers assy with the adjusters backed off & adjust each valve. Good luck.

Like I've said above, this has been done - multiple times using this and other procedures which produce the same final setting. And, the adjustment at zero lash, or zero lash plus, hangs the valves open - all of them.

This is not the first time I've adjusted the valves on this car - two engines and two different head and valve train configurations - never have had a problem...until now.

Did you degree the cam ?
Is the cam spacer on the cam behind the pin with the inside bevel toward the journal, not to be confused with the cam retainer ?
Is it possible that the valves are closing and the the cam duration is making lower vacuum and rougher idle than you expected ?
Loose lash will get better vacuum and better idle because it cuts down on duration, cannot run it that way .

All good questions. Thanks.

At this point, I have no other option than to pull it apart, inspect everything and put it back together.

Update:

Replaced adjustable rocker assembly with non-adjustable rockers and push rods. Obviously, it quieted down, but ran like crap. Neutral idle was ok but in gear it was making some odd noises and idled ruff. Vacuum was lower also.

Had to put the adjustable rockers back on and put up with the clatter.

I'm thinking it has something to do with the lifters. Thinking I'll replace them and put in the stock cam I have on the shelf.

It looks like the lifters are not bleeding down after adjustment.
They are acting like solid lifters.

Take one out and see if you can push the plunger down away form the retaining clip.
If so measure how much travel you have.
Most anti pump lifters only have about .100" worth of travel.

That's been my suspicion.

What would cause them to act like that?

Can you depress the lifters? Is it possible that when installed the lifters were fully pumped to the top and can't bleed down now?

During the first couple of times I tried to adjust the rockers, as I would tighten them to zero lash and stop, a couple of the lifters would sink enough for the rod to become loose enough to twist. But, only a couple, not all.

I tried depressing them yesterday when the rocker assembly was off and they didn't seem to move at all.

I'll have to pull the head and remove them to really be certain.

It’s not as easy and a bit messy but before you pull it apart why not try adjusting them with the engine running. Loosen til they tick snug til they stop then go 1/4 turn more. Good luck :thumbup: :nod:

Are you measuring your lash adjustment or doing zero lash and half a turn?

I do a collapsed lifter lash. Holding the lifter compressed and measuring between the rocker and valve stem.

Ford manual for '63 shows 0.067"-0.200" lash for hydraulic lifers. Of course for OEM lifters. I shoot for the middle.

Maybe an issue with those Sealed Power lifters?

That is not zero lash!
Zero lash is when the pushrod barely begins to get tight and the lifter plunger is NOT depressed.

Then you go another 1/2 turn from there and the lifter plunger depresses about .050"

Did I read you correctly?

Adjusting with the engine running was the only way to figure out when the valves were actually closed - steady idle and steady vacuum needle. However, ended up with a very loose and noisy valve train.

There should be a spring under the plunger that keeps it up against the retaining clip.

Ok great now what's the condition of the adjustable rocker assembly? Dose the shaft show any signs of wear under each of rocker arms position, and or for the rocker arm bushings? The Info stated from your above update leads me to believe that the adjustable set of rockers may have quite a bit of wear in them compared to the non adjustable set. Good luck :thumbup: :nod:

Yes they are good questions and the first two must be done but the third is not important or you could be chasing your tail.
If you take out the lifters they should be put back in the same place that they where broke in at.
New cams should be lubed with brake in lube paste on the lifter face and cam lobes and ran at 2000 rpm for 20 minutes with no idling.

The adjustable rockers were on this engine (and a previous one) before the new cam was installed and worked just fine.

I've never had an oil pressure issue with this engine and the last time I put a gauge on it it was over 40 at idle - of course that doesn't mean it still is. However, there is so much oil passing over the valve train I have to cover the plug wires to keep them from getting soaked. Made the mistake of running the rpm to around 3k - it was a gusher.

Also, the idiot light hasn't come on and I know it works from past experience.

Thanks for that. Very interesting.

I ordered new lifters last night. We shall see...

Final Update: Never was able to figure out why I was having so much trouble getting the valve train to function properly. Took it all apart yesterday and inspected every part and how it was installed. Everything looked fine and was installed properly.

Reassembled it with new stock cam that I had on the shelf for five or six years. Put in new lifters - same brand as before - Engine Tech. Engine ran smooth and quiet from first fire. Ran it 2000 or so rpm - no tach, just by ear - for 20 minutes. Buttoned it up and went to dinner.

Took the wife to lunch and ran errands this afternoon - car never ran this good - she was impressed...I call that a win.

Thanks for all the input and suggestions - I really appreciate it.

Really don't know. It was the mildest performance cam Vintage Inlines sells for use with an auto trans. So, there shouldn't have been a problem.

I'm suspecting something to do with the lifters. I was told and read to soak them overnight in oil - which I did. This time I washed them off with mineral spirits and then pumped them with oil prior to installation. Seems to have worked. But, I don't know.

New lifters with the performance cam may have worked, but I didn't want to waste the lifters if it didn't - plus having to pull the head again.

Thanks and best to you also.

I was wondering if it might be a pushrod issue.
Did you go from a stock head gasket to a newer thicker style?
Was the head milled?

I was wondering if it was some kind of factory oil stuck/varnished into the lifters. I wish you'd just swapped them out but I completely understand why you swapped them both.

I'm using the same pushrods I've been using with the adjustable rockers before and after the cam swap.

This engine - up until the cam swap - was factory stock. It had never been apart for any reason. It came out of a 66 Mustang with 60k miles on it. The cam and lifters were getting tired so I swapped out the original rocker assembly with an adjustable assembly hoping to give it a little more life.

In the process of swapping the cam, I replaced the head with a rebuilt head that was on the engine in the car when I bought it. The head appears to have been surfaced, but not shaved. I replaced the original metal head gasket with a Felpro.
