Mark Shead brought to my attention low friction coatings, like DLC.

Does anyone have any experience of these and what the costs are?

I'm thinking of doing something with a Camshaft.

 

I have used these in my engine and when stripped down it was nearly all still there
I have used it on pistons, cams, bearings , crank and valves,
I use these people,

These companies do the proper DLC and not the cheap stuff, I dont know the price but if it saves you cams then imagine how much you would have saved. All the F1 teams and just about every proper race engine uses this stuff now days.

at work we use a company called Sermatech in Ripley, they do praticaly every coating you can think of.

 

I once asked dlc coating to the pistons from one Finnish company called www.diarc.fi and they quoted me price of 60eur/piston, but that was more than one year ago.
