As above, must not be a re-grind and followers must be kept in order with the cam, vernier not essential but a plus.
What have you???

I sourced my cam kit, cam/springs/pully through these guys, it wasn't a re-grind and to my suprise when I installed it, it timed up @ 112 degrees:eek:
As for followers I used some that had be checked for wear (concave faces) and used the flatest ones I could find. My engine hasn't been apart since so as for being able to comment on the longevity of my cam lobes I can't and my motor only made 209hp @24 psi and I'm still non the wiser for why. I hope the followers I used haven't done similar to my shiney new camshaft........
If your willing to fork out then new followers are the best bet imo;)
Cheers for that Phil - I remember yours at Scoff's RR, you did quite well - what turbo are you running? and If I remember rightly yours pulled hard to 7k+, Mine starts dropping orf at 6.5k, so if I were you, I'd be a happy bunny.Quote:

anyways this is of no use to you getting the parts your after so I will stop mucking up your add .....:laugh:
LOL, don't worry about it. I think I'm going to Have to bite the bullet and buy new cam and followers. :cry:Quote:

Any good engineering place should be able to help you out..Quote:

Or am I talking out of my arse as usual?
Where did you get yours done Logg
My mate built my engine all my bit's would of been sent off with his work stuff I think they use H. T. Howard. As Dave have said I guess most engineering shops should be able to help you.Quote:

Surprised no-one's ever looked into getting these made? They're only a 'bucket' with a hardened face after all. Surely they can be produced & supplied for cheaper than the £16 (*) per follower that Renault charge?
* Or that's the price they were around 8 years ago anyway.
I'd be interested in a set if anyone was looking into it..?Quote:

For those who had there's re-worked - How much did it cost?
There's two sizes as well. Not sure what they are but It's something like 1 or 2 mm difference in diameter. I'd look into having the block bored out to remove any wear and start from fresh with the larger size, not sure if that would be possibl though e.
Measuring your old ones is fun as due to them becoming ovalled you have no idea which size you need, I gave up and chucked the old ones back in as only had a mild reprofile and never had any issue with the cam ect.
19mm & 19.2mm rings a bell.
:agree:Quote:

Been in contact with catcams, they recommend new followers but also say they can clean up and refinish them for £10.00 + vat each, so £12.00 each.
For £54.00 I think I'll stick new in.
Got the Cam out tonight - looks a bit poo!

Let me know if you can't see these.
mine was similar apart from that one lobe thats worn flat.was it a billet or regrind before it went in? how many miles has it done?
It was a regrind, and I'd say about 15K of hard miles. Not good really. I've never used top brand oil, always semi synthetic. Might be something in that?Quote:

No - Turbo's have been fine. I'll be using a quality oil from now on, So I suppose stick a new cam in and away we go.Quote:
