As title really, can anyone give me an average price of a camshaft regrind? Cam is a MG metro one.

Thanks Iain.

Simply get an exchange camshaft...... finding someone who can regrind a mini camshaft correctly is going to be a challenge

Really? I thought it was quite a common thing, obviously im wrong.

Ive heard people talking about re cutting them before, as ive also heard its not a good idea to put a 2nd hand cam in a different engine?

I agree with MRA-MINIS. its not a common thing to regrind a cam shaft. Crankshafts yes, they are often reground. I wouldnt worry about useing a second hand cam so long as its in good condition. You will have to change the cam followers anyway so I cant see why it would be a problem.

Ok, my mistake then, i must have got mixed up with crankshafts.

I guess the cam i have can go straight in then, its in good condition. It'll be going in a fully rebuilt engine so followers will be changed.

Thanks Iain.

The MG cam will go straight into an engine. New followers will need the initial bedding in at 2000 - 3000 rpm for 15 to 20 minutes or so, and is recomended using a good cam lube on the lobes at the initial build of the engine.

A camshaft that is in good condition will need no other work to it, for it to function as it should in any other engine, providing the cam bearings in the block are in good condition and the followers replaced.

When people talk about 'regrind' on a camshaft, it reffers to a factory standard camshaft that has had the profile and duration changed. Not so long ago most after market performance camshafts were all regrinds, which tends to reduce the lobe base circle diameter, with the expensive option of a billet cam, whereby the cam is machined from a solid bar, to the same lobe base circle diamter as a factory cam. Regrind cams were on an exchange basis to keep the cost down, with a surcharge for an outright purchase. Nowadays there are less and less 'exchange' cams so cam grinders now pretty much just do billet cams at the full price.

Great bit of info, cheers mate.

What I meant....... Yes camshafts can be reground, however it is not normal for a engine reconditioner to have such machinery to do the job.

There are a few specialist camshaft manufacturers or re-manufacturers that do have the required equipment, the likes of Kent, Piper etc...

Crankshaft, yes thats a different matter............... they can be reground and most engine remanufacturers will have one.

The cost of a re-profiled Mini cam on the Newman website is £60+vat.

The MG Metro cam is an excellent cam anyway - if it really IS an MG cam of course..... Post up a picture

Sorry to post on here but what features does an MG Metro cam have which make's it stand out from any other cam?I have a new cam lay about and I'm not sure as to what it is exactly.
