Break in new cam follower old school flat tappet cam swap style?

[377Z]

i.e. 10-20 minutes of 2500-3500RPM operation? Typically done because lobes for flat tappets are ground with a very slight offset on the ground surface so as to spin the follower during operation. You can see evidence on used followers (including our HPFP followers, looking at my slightly worn 56K mile 2005.5 2.0T cam follower I just replaced) in the circular wear pattern.

I used some engine assembly lube on all surfaces and will probably go out for a 10-20min spin, but curious as I searched and found no reference of it.

[377Z]

Well, went and did it anyway. Since doing this in the driveway is boring as fvck, I took a leisurely drive around the neighborhood, varying the RPM between 2500-4500RPM.

Original cam follower lived to 56K, will probably check it in about 10K to see how its doing, presuming we don't upgrade the car to a larger one for the family.

There is no break in required for a cam follower, nor is any special lubricant required.

Might want to reconsider the 10k check to 5k check......

5k is a bit excessive. I've got an upgraded hpfp and I just simply change it every 7500 miles when I do an oil change or there abouts. I could stretch it to maybe 15k safely, but I'd rather not risk it.

[kegobeer]

I check mine at 10000 miles. Other than the JHM tune, I'm unmodded - and the wear on the cam follower is not bad at all. I still swap it out then, though - no sense in putting the old one back and then pull it again in another 5k to check it (I wouldn't chance it going 20k for fear of failure).

[groundround]

Crazy every 5k or 10k!

Operator: please skip over reading this post as to not bum ya out.....


naw I meant check it at 5k and replace at 10k regardless of condition... Remember Operator had one punch through at 3k (sorry Dave to rehash this)..

Guess I should stock up on the JHM blowout price, but what a 'f'-in nuisance.

I was afraid of what I would find with 56K on it, but its not bad (for what it is--if I saw this on the lifters of any other motor I'm familiar with I'd siht).

I did the traditional flat tappet break in routine because it looks fundimentally the same as old-school flat tappet motors that require break-in so I did the whole shootin' match lube and all. But if no break in is actually needed I did no harm to it, so not quite win-win, but maybe win-draw? Will be interesting to see what it looks like in 5-10K, though odds are I'll have one on hand at the next check and would probably just change it unless it looks new.

What a 'f'-in nuisance... but the 6 speed (and lack of problems knock on wood) keeps it in my garage for now.

Every car is different. My recommendation is to check it every oil change, til you get a good idea of how long it lasts. I now check mine at the 3rd oil change interval after replacing. If it's still good, I'll probably leave it and replace on the following oil change.

i just put one in 256 miles ago and now i'm on phone with AOA trying to grt them to fix my 2008 with no extended warranty

Assembly lube on the cam follower is a good idea for when installing a new one. I do that for all of mine.
We also have cam followers for $27.50 =]

I let mine soak in motor oil before I installed it.

I check my cam follower every day when I get to work, then again when I get home. its really the only way to be sure.

That's it? I check mine while driving to work, and when driving home.

Every car is different.

This! all this talk of changing every 5k is a waste if your car is not destroying them in 5k. My last 2 I checked the first after 20k, the next after 25k, no noticeable wear at all. I may leave the next one until 30k, but might just go ahead and swap them out at 25k anyway (25k for me at the moment is about 2 years of driving).

I've got an '82 Suzuki FZ50 in the basement actually. But that thing is WAY too slow for the roads I take to work. It can barely top 30 on a flat surface. I shudder to think what it would do on the massive hill I drive up every day.

First time I checked mine was over 113,000 miles and it really wasnt horrible. Had some pitting but overall still not bad. The pitting just holds more oil..yeah thats it. I guess it doesnt hurt but I wont be checking mine every 5 or 10k thats for sure.

Heh, I know, just came in on Friday! Such a deal.

I will probably check it sooner than later despite the original lasting to 56K, & then determine the following interval, etc.\. Reason is, there is some wear/pitting on the follower, so there should be some corresponding wear on the cam lobe. No way to tell how that will affect the new follower except to inspect after some run time. Too bad there isn't some easy way to dress/polish the lobe in place...

[Jovan]

I have had my car for 14k miles now never checked it... now i know what i gotta do..

[jimrobbington]

I would venture to guess that driving habits have somewhat of an effect on wear as well. So no matter how many miles are on the car, if it's new to you, i would always check the can follower immediately, and continue to check it every oil change to see how it wears the way you drive.

This guy knows what he's talking about.

This guy knows what he's talking about.
There's absolutely no reason to risk a follower failure for a part so cheap (thanks JHM!) when the damage can be so immense. It will never be a problem if it becomes standard maintenance, and once you've done it a few times, it should only take ~1/2 hour.

I've got this down to a science. I've been driving my car for a little over 70k miles, and I'm at 146k now. You can see the very first follower is the worst. But that's not bad for 74k miles though. That was driver 1. Then driver 2 comes along, and you can easily see i would never get 74k out of a follower. Not only because i drive a lot harder than the previous driver, i also tuned the car almost immediately. Also, as you can see, rack follower is worn a little less than the last, because i changed it a little earlier each time. If i change it every ~15 k miles, it will look like the last one on the right. Even going 20k would probably be fine. Better safe than sorry.

Heres what My old 2006 b7's follower looked like at 85k miles:

Heres what my current b7's looked like at 54,000 miles.....

And this one was run for roughly 35 miles, from the dealer back to my house, and from my house to my buddy's house.

Conclusion: Cam Followers are the bestest...

Oh don't worry, that was 2 years ago. (however I'm still bitter)

The good news is I'm keeping the B7 now, so I'll be ringing you guys up next year sometime for a tuneski! (and hopefully not a new clutch but also maybe a new clutch!)

WOOOTT!!! I am so excite!

[2kwik4u]

SOOOOOO....What I'm reading is that the 154k on my cars factory (never checked) cam follower is probably the equivalent of driving a ticking time bomb that will hurt and mame small children if/when it finally fails? :D :D

I can't believe people are replacing these things at 5k intervals because the finish is worn off!

I'll be picking up a JHM follower in the near future to change at the next oil change, not due to any real symptoms, but because reading any number of threads here has me scared my car is going to implode at any moment.

Just got these code on my car. Is P2293 for camshaft/cam follower?

Are these codes related to camshaft?

[jimrobbington]

Hmmm, possible, but could just be any number of other fueling problems.
