CAm lobe wear. How much is too much????

[winfred]

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

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

Don´t you just love driving a V8....It´s a nice upgrade, this combined with a propper remap on the dyno turns the V8 quiete rev happy, especially from 3500 rpm onwards. I don´t 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.
