Rover V8 camshaft running-in - CMark {P}
I am just about to install a new camshaft + lifters in my 1986 3.5 V8 Range Rover rally-car-on-a-shoestring (286k kms) and I have mislaid the information I had regarding the special running-in procedure. i.e. not letting the engine run at idle for the first 30 mins.

Does anyone know where I can find this? Done an hour of Google and re-read the RPi site but still cannot find the regime.

Not certain exactly why a regime of x minutes at y rpm followed by p minutes at q rpm etc etc is required. Someone said it places too much stress on the lobes at low speed??? Or is it a lubrication issue??? or is the speed required to get the lifters to turn properly on the slightly "sticky" cam for the bedding-in process???.

Thanks in advance, CMark

Look on www.pumaracing.co.uk - there's a very precise procedure for running in a new camshaft (and he tells you why it's necessary). There's also loads of other fascinating info about tuning - especially if you thought a 'performance air filter' or 'performance exhaust' was any use at all!

Some good advice on Puma Racing and you could follow their general advice if you don't manage to find out the proper running in proceedure. I used to know it off-by-heart from when I rebuilt my SD1 V8 motor, but I'm afraid it's faded into the mists of time now. Why not contact your cam supplier? Failing that get in touch with Real Steel, who specialise in V8s of various flavours (they're in the London area somewhere). Alternatively try John Eales in Coventry - they used to tune loads of SD1s and Range Rovers.
