What is the material used (preferred) for the newer lifters that are compatable with replacement camshafts?

  

I believe it's a metal hardness/compatibility problem. FoMoCo (steel?) lifters would likely work fine with earlier NOS Ford cams.

Much discussion re: this subject can be found in Y-Block Mag. back issues.

Marc, I looked through my records and found a receipt from 2003 for 2 cams and 2 sets of lifters. These were Schneider cams, a 256F and a 264F. I don't know which one was in this engine.

The lifter manufacturer was most likely Stanidyne but that's a guess at this point. Overall we had good luck with their lifters. This was before the Chinese lifters hit U.S. shores and after Eaton Corp. quit making Y-Block lifters.

I'll try to help you if I can.

FYI, the Schneider cams lash @ .012-.014", not factory spec. That's where a lot of the noise was coming from. 2003 was also before we started cutting the grooves in the cams for oil flow.

Daniel: if your adjusters are still good after 20K, they must be made correctly. If yours were defective they would have worn out in <1000 miles.

 re: rockers and adjusters, I don't use the black adjusters.

Thanks Mark. It sure is a pisser, considering the big $$$ I've got into this thing. Busted lifter & all, the thing still ran like a scalded cat, and sounded real sweet through the smitty's. Had a real nice bark to it. This motor's going to sit in pieces for a while until my future's a little more certain. For those of you on the east coast or who follow aviation news, I work at the Pratt & Whitney plant in CT that's slated to close next year. This thing will have to wait until I'm sure of a steady income.

Reading through this topic I see some discussion about inferior lifters.What is the consensus about original Ford lifters.Just curious about why they would not be used instead of aftermarket?Marc,Sorry to hear about your motor.

  

It took a while, but I finally dug into the engine. Sure enough, I'm fishing chunky lifter bits out of the oil pan. AT least one cam lobe is wiped out, a few more don't look so hot either. Looks like I've got a little work to do. At least the old motor is back in the car and running well, even though it tends to mark its territory.

A little on metals, the company I work for makes conveyor chain and they had a factory open in china and thought they would produce some chain there. Well it a takes a large interference fit to press the pins into the chain, this actually makes the links stronger by equallizing the pressure around the side bar. As it turned out the chinese factory could not produce steel strong enough to allow this large interference fit and the sidebar would crack when the pins were pressed in. I was in China for a month and discovered that their formula for making the steel cannot compare to other countries. Their raw materials and processes will just not allow them to make a quality grade metal strong enough to make our chain.

Needless to say the company wasted lots of time and money only to move the chain assembly back to US.

Very confidential so no names are mentioned but stay away from any Chinese made metals, they plainly cannot produce near the hardness or quality of other countries metals.

Lifter , cam failures, same reasons.

Still not sure what the problem is, but I don't like the noises I'm hearing, so the motor's coming out this weekend. The rockers, cam, & pushrods were all new, purchased from John M. a few years back. I'm not sure of exactly when, I'd have to dig up the receipts. I recall when I bought the cam there was talk of some cams not having a deep enough groove. I checked mine when it arrived and it looked ok. Who knows, maybe it's not. Once I tear the thing down I'll have a better idea of what's going on.

Hey John,

I bought a set of those 3 1/2 yrs. ago. After you recommended the black adjusters being best, I assumed they were the same rockers YOU were selling (?). I DID notice the design/producer had changed a couple years back (replacement for lost jamb nut obtained from another seller came with an adjuster I didn't use, which had different thread). Anyway, after nearly 20K miles, lash still stable. Did YOU have trouble with the earlier versions? Can you be more specific re: failure symptoms with the "JUNK" examples?
