Cam lobe wear. How much is too much???
1) If it is your current 535a?
2) If it is on a head that you are buying to replace head with worn cam lobes?

Why not just get one of the aftermarket performance ones? I think it was Jeff N who mentioned that Ireland (?) has one for < $200 (big ?).

shrick cams? between a cam and a chip things will be happening quick! On my V8 the cams dont turn on till after 4k so I dont think I would gain much...probably why they arent available.

Itīs easy to see when can wear is too much, grooves on the " chrome" center part of the lobe indicate clearly that the cam is worn. If you want to upgrade to a fast road cam and a chip, the M30 will be a blast , especially with the kick down function. Do always buy a cam kit including stronger/stiffer springs.

Fast cams for the M60.....

They are available from Bilas tuning in Germany, a very known and respected tuner in Europe. They don' t come cheap though. Take a look for youselves.

wonder what the stock specs are since they only have 1 profile.

that sounds about right, bimmer cams generally run $400-500 each and you have 4 of them

Donīt you just love driving a V8....Itīs a nice upgrade, this combined with a propper remap on the dyno turns the V8 quiete rev happy, especially from 3500 rpm onwards. I donīt know what it will do in the E34 body, but in the german E30 I drove last year it was a blast.

You'll really know the wear is too much when you can't get the correct adjustment when setting valves. That's the time it starts affecting things.

This happened to me so I bought a new stock cam for $169 from www.eap4parts.com.. plus cam seal and gasket set.

Another option is to get little valve caps that can on top of the valve stems- these are used when a cam's lobes are ground (or worn) below normal size to regain the adjustment. From memory they cost US$6 each or so from one of the older US bimmer workshops that grind M30 cams. On my M30 three of the the middle lobes went due to a clogged oil sprayer bar.. is yours the same? I ran mine with the valve cover off afterwards to check each lobe was getting oil. (messy bu thorough).

Of course I could have fixed it with much less hassle by popping these little caps on... I guess it depends how much you care- I'd use caps second time around.
