Ford 7.3 Lifter/Camshaft Delaminating Issues

Starting to see quite a few reports of lifter/cam failure on these engines due to delaminating. Shows up around 35,000 miles. Hate to see that; we've dealt with lifter and cam issues with LS and Chrysler Gen III Hemis until we're blue in the face.

Here's an example.

Welcome back to pushrod goodness fellas. Hey the guy in the video mentions something about LS style lifter. No as I understand it it is an off the shelf lifter that GM and Mopar currently use in the LS and Gen III hemi respectively.

The bean counters at Ford couldn’t resist the temptation to simply buy an engineered lifter rather than put an original Ford one in there.

What a tragedy. Money crunchers ruin everything.

Ya, we’ve never heard of any lifter problems in the LS line.

Listen guys as I’ve said in another thread I’ve seen this before. The 6.0 & 6.4 Powerstroke used the same lifter. Possibly the same supplier. They had problems with those tiny GM sized lifters as well.

The standard Ford lifter size was .874” while the typical GM lifter came in at .842”.

This step backward to the off the shelf GM size has to be contributing to the problem I suspect. It certainly did in the Powerstroke engines.

With the smaller lifter bore diameter you obviously have to spec out a smaller wheel. That smaller wheel is a problem in my opinion.

LS and Mopar and even the Powerstroke 6.0 and 6.4 have had lifter problems. The bean counters at Ford apparently are idiots.

You know what fixed the problem in the Ford built 6.7 Powerstroke? Yes a large diameter (1”+) with a correspondingly larger wheel.

I hope this is a bad batch and not a problem endemic to the design. The lifters in a stock engine shouldn’t be too overstressed.

The camshaft in a Godzilla is pretty large in diameter. I think it’s 55 or 60 mm. The larger you go the faster the surface speed so there’s that.

I think Ford did their math right. Normally things like this are due to manufacturing defects.

The silver lining is that these seem to be failing within the warranty period and possibly, hopefully these replacements will allow a stockpile of rebuildable cores to accumulate and maybe feed the guys that want to hot rod them.

Cautiously optimistic that this will be resolved quickly.

Why are you blaming the lifter when apparently there are documented cam failures and the lifter was OK? Nevermind, I know the answer! Lol
Maybe a cam core issue?

……and you would be wrong. I’m simply stating the facts. We have an off the shelf lifter that has already seen failures in other manufacturers engines. The GM and Mopar equivalent.

The bastard bean counters undoubtedly stepped in and steered (forced) engineering to use the smaller diameter lifter because that is a massive savings.

I don’t know how that is blaming anyone but Ford for this dust up. I could give two shits what GM and Mopar do and I don’t jump into threads criticizing their shit. You Chevy boys do that.

I looked into this 440. As of three hours ago my local busy Ford dealership has had exactly one 7.3 engine job. It was an Amazon truck and was not cam or lifter related.

I also looked around the internet to see what the hubbub is and I found three videos from the same technician regarding this issue.

To my knowledge there are no other sensational videos that pertain to Godzilla cam/lifter failures.

I noticed on a Ford truck website there are a few customers with this issue and all that I found are being taken care of under warranty.

This is my fuck you sentence to everyone that has to make this a personal attack on me. I feel after 25 years of Ford dealership experience that this is pointing to a manufacturing defect and is probably “batch” related.

Im kinda pissed off at a couple of you guys that show me disrespect constantly. I’m not some fucking kid with no idea about what’s going on.

I certainly could be wrong and this could be a design failure but I don’t think so. I think any group of decent engineers should be able to spec out a lifter of sufficient durability provided the design specs have been met.

So there you go.
