Has anyone out there encountered any bad lifters that the vendors are supplying? I installed a complete set of oversized lifters with a new Stipe cam & with only about 800 miles on the engine developed a dead miss. Turns out no compression on one cylinder. Pulled the cam & lifters, one bad lifter & an engine full of cuttings! Cam was like new and all the other lifters were like new. There was no binding of the lifter or valve train. I'm running a Fronty head with proper valve springs & pressurized oiling system. My thought is this one lifter was not harden or not properly harden. Anyone have any thoughts?Bad lifterSame cylinder good lifter, no wearBad lifter

Sounds like more China trash.

The new lifters I received this winter all had a teat in the center that would have messed up the cam lobe. I had to face them on my valve machine. PK

Herm Kohnke, about 15 years ago now, did the short block for my '14. He returned the lifters I'd sent with the block, saying they were no good. He went on to explain that there were two manufacturers of adjustable lifters for the T; one make was good and the other wasn't. The same firms probably also make the solid types. Herm explained the difference and how to identify which make was which, but like an idiot I didn't write it down; I thought I'd remember. I do know that I've had no trouble whatever with the ones he supplied. Maybe Herm can chime in here.

How do we get the parts vendors to state who made the part?

I have had the same new part fail. When i had the engine built the re-builder that only builds model T engines said the lifters damaged the cam shaft. I haven't had these same troubles with model A engine parts. Tim

I have had this on model A suspension parts!Such as a spring that lost its tension, the front spring perch snapped driving down the road ect. All after a major restoration. Most of the parts are not the best quality but the old stuff is worn out after near a 100 years.

I would think that if the parts vendors care about their reputations and their customers satisfaction (some do, some don't), they would want to hear about these problems so they can address the issues with their suppliers rather than continuing to provide parts that are trash. YMMV.

Seen this happen a few times. There was a batch of them made years ago that were no good. I no longer trust sets of lifters from swap meets or other unknown sources. I only use new lifters from the best vendors. Especially with overheads. Even with the correct springs, the ratio of the rocker arms put heavier stress on the cam and lifters. For these I use 292 Ford lifters with a cup for the pushrod.

Erik,

For what it's worth, I used those 292 lifters in my Model N rebuild. Once the cup is just ground away, they're the perfect length. All the other dimensions are the same as well.

The 292 lifters are .500", so you have to ream out the block to use them in a T. At that point, the block is committed to overhead valves or other large diameter lifters for a flathead.

What vendor supplied the bad lifters? This isn't for vendor bashing, I need a set and want to avoid the same issue.

I'm not sure where the bad ones came from, but I can say the ones I use from Lang's and Snyder's are good.

Bob Richmon - Can you tell us where you got your lifters and how long ago?
