Well, my new Comp Cams XE274H didn't make it very long. I've been having some problems with it every since I installed it, and after some time with them on the phone,and doing some different things, we're almost certain a lobe went down. I'm getting ready to go pull the intake and check it out.

[mmikeclass06]

thats no good. are they gonna replace if it did go bad?

[69fastback]

I hope so. I'm waiting on a call back from the warranty department, but from what I understand, they're usually pretty good about warrantying stuff like this. It sucks I'll have to tear it all back apart though, and it's still going to cost at least $100 in gaskets and fluids, not to mention my times.

[69fastback]

Good news. I just pulled it apart, and found a collapsed lifter. Maybe I'll be ok.

check the bottom of that lifter.if it is mushroomed.or has a hole in it ,you need to take a good look at the cam.

[69fastback]

The bottom of the lifters look fine.

The warranty guy called and said if I replace the lifter with a new one, on a cam that already has some use on it, it probably will wipe the lobe : . It's amazing to me that a flat tappet cam is so fragile. I wish I would have just went with a roller one now . He did tell me, if I want to pull the cam and send it back, they would go ahead and send me a new cam and lifters, so that won't happen, but damn what a PITA.

My other options are to take the chance with the new lifter, or check my lobes, and if they're ok take the lifter apart, and see if there's some trash in it, or a burr on the pluger, clean it up, and put it back in.

dont put that lifter back.i have seen a lot of lifters replaced single and do fine.just get a bottle of cam break in lube and chang oil and filter to start.might save a lot of trouble.

[69fastback]

Well, since they offered to replace everything, I just decided to do that. It's a PITA, but it would be crazy to not take them up on it, so I'm getting ready to go up and pull the cam again. I think it will come out without pulling the engine, so maybe it won't be too bad.

[460brevill]

todays oils dont provide a good breakin,so add a bottle of cam breakin additive to it.good luck.

Valvoline VR1 claims to have sufficient zinc levels for flat tappet cams, but I was still using the break in additive. I have the cam out, and it looks fine, so I guess it was just a lifter problem. They still want me to replace it all, and they're doing it under warranty, so I may as well do it.

Absolutely Fastback.. And without mic'ing that lobe you won't know if any minute wear exist. You have it torn down now take the new cam and lifters.

It's good to hear the company will back there product to replacing it with no arguments. Very cool.

I actually checked it with a dial indicator, and it checked OK. I do have to say, I'm happy with the warranty department. I called asking for a lifter set, and they practically insisted on replacing all of it.

[460brevill]

good deal.sign of a good company.good luck.

I am actually quite surprised cam companies are so quick to replace cams with wiped lobes. It is so common now, they have tio be losing their arses on warranty claims

Yep, but it's widely known that it's an oil problem, and with all the technology out there, they should be able to build a cam to adapt to it.

I think forums like this have helped customer service, because if my new cam and lifters were ruined, I'd be plastrering it on every message board I knew of, if they weren't going to warranty it. Instead, I'm telling people they insisted in replacing it all. There are lots of companies making good products, but customer service is what makes or breaks compaines.

This is very true. There are two things that a business needs to succeed; back breaking labor and good customer service.

Totally agree, Cs is the reason I order everything from mustang depot. Had a good experience when Jay really helped me out so I always order from them.

And yes unfortunately oil nowadays suck, low zddp in pretty much every oil. I would look at using Joe Gibbs "hot rod" oil. They claim it has very suffiecient amounts of zinc so it should be great for flat tappet cams. It is a bit pricey though but better than having to change the cam again.
