Because you have to have valve function to start the motor, lifters are pumped up via the oil gallery, which "usually" sees the oil from the pump first to get them functioning first. They fill via a hole in their side and bleed out from the top to push oil up the push-rods to the lifters so that oil gets to all the upper valve-train. So it is really rare to get them not to pump up under 40 PSI of pressure. They have to be really broken.

The cam bearings also get oil first along with the lifters, so the reason I asked about where the offending lifter was is to see maybe perhaps a cam bearing was installed wrong and blocking the oil path. Doubt it now if only one lifter is acting up.

Bummer deal no less.

Although... now that I think of it, I think the 200 gets its oil to the head via the head bolt passage and the upper rocker assy oils all the top bits. I was in V8 mode.

Pull the head and change the lifters. Do it now before there is more damage. Wiping a lobe means tearing the motor about to clean out the metal bits that will go everywhere. You don't want that.

[Jeff W]

I guess even with only one new lifter you will want to remember to do the fast RPM break in routine.

Wiping a lobe means tearing the motor apart to clean out the metal bits that will go everywhere.

Is there a way to tell if the lobe hasn't already been "wiped"? As I said, it's been this way since... well... all along, I guess.

[Luva65wagon]

Pulling a lifter and looking at the lobe is really about it Gary. Wouldn't cause the lifter to not pump up though, I don't suspect.

[MacDee]

So...
Apparently the cam lobe at the offending lifter can be checked by verifying its lift. Carter fabricated a checking "push rod" that centers itself and rides on the lip of the lifter body. It can used for checking and comparing lift.

Would it be possible to get some help with this some weekend in early April?

Roger, you said you have a dial indicator? Will it work with an aluminum head?
Does anyone have a 13/16" box wrench (for turning the engine manually). My wrench set only goes up to 3/4", and there isn't room between the damper and the radiator for a socket wrench. (If not, I'll GET one....)

[Luva65wagon]

It is magnetic, but that won't be a issue. We'll rig-up something.

Set a date and let's see what we can do.

I'm sure, also, I have a 13/16 wrench.

[redfalken]

If I'm available I can lend a hand. I have the Kennedy toolbox I bought from Roger full of machinist's tools, calipers, dial indicators with various stands, extensions, clamps, etc. that my dad sent me a long time ago. And I can bring my 13/16" too. Just in case.

[SmithKid]

Count me in, too (if I'm not fishing).

[MacDee]

How about Saturday, April 6?

[redfalken]

I think that works for me.

[MacDee]

Okay...
I'm tearing into it this Saturday, April 6.

The plan is to remove the valve cover and rocker shaft, substitute a "test" push rod at various lifters, EXCEPT for the bad one, and measure lift with a dial indicator. Establish a "good" lift reading and then do the same test on the bad one (#2 exhaust).
Depending on results, I may need advice on what to do next.

I just ordered a new lifter and a head gasket set... just in case that is all it will need....

I will probably open the garage around 9:00.

There will be snacks, coffee, etc.; pizza run later if necessary.

Are the dial indicator and the 13/16 box wrench still coming?

[redfalken]

I'll have to play it by ear. My landlord scheduled a new refrigerator delivery Saturday. She won't know until 8:00am what their 2 hour window will be. And I'll have to empty the old one before they get here.

So I hope to be there but we'll see how it goes.

[MacDee]

Okay!
Two "maybe's".
If no one shows up, I'll go buy a dial indicator and a wrench, check the cam lobe lift myself as best I can, and report the results.
Unfortunately, I don't really have another window of opportunity coming up any time soon. Gotta do this on Saturday.
