Cam follower, new & old

[coolhandluke]

At a 120,000 I thought I should change the cam follower after reading so many horror stories.
Out of interest I measured the thickness of the new one, it measured 0.080".
After changing it over I measured the old one, it measured 0.076".
So less than 0.005" wear in 120,000 miles.
Car has regular oil changes and isn't mapped.
So if there's anyone with similar milage I wouldn't be in any rush to change it.

Do you have any pictures? I’m pretty sure that amount of wear is more than the thickness of the DLC coating which means it would be close to failing. I’m surprised if there was any of the coating left.

No, no pics at the minute but your right the coating was worn.
The coating must be microns are a few thou thick at most.
Is it the coating that's important?

This is a good visual indicator

Nice one, had never seen that before.
I'd say mine was at Stage 1, any wear of the coating was still within the holes around the periphery.

Mine was pretty similar after 110k miles to that off stage 1. Did it again at 145k and it didn't really have much of a mark on it! Was going to do it to the car at 175k there but sold it at the are of this month, so I now have an extra cam follower to sell for bad money!

And I could have been that person to give you a bad price for it lol
If i ever get a Mk7 I'll give you first refusal on my MK5.

Wow, that's impressive.  I changed mine last month after 40k miles. Definitely 'stage 2' comparing to the photo above.  Car is stock by the way.

That seems like a lot of wear for standard and 40k?

I could be interested in that cam followed for bad money

PM me with a price and hopefully we get a deal sorted :)

Thanks

0.080" is 2mm for those living in the 21st century 

Impressive wear on your example.  There's no rhyme or reason to follower wear, but excessive revs, poor maintenance and aftermarket fuel pumps are definitely factors in killing them off quicker.

I did mine at I think about 110,000 miles and it looked like the new one!
