Poorly Cecil....

So, noticed another slight engine rattle from the front of my car the other week.

It's down at Munich Legends right now being fixed, the problem is my camshafts are worn and have play in them, which means new cam shafts, rockers and associated hardware and a head rebuild, really not good, but needs doing.

I think this all stems from the work I had done 2 years ago on the vanos gears etc, where I am convinced whoever did the work didn't do it properly, but that doesn't really matter now as the problem is there and needs fixing.

I know this is one of those topics where it can be hit and miss, but is it worth putting more aggressive high lift cam shafts in the car for that potential of a little bit of more power?

Been doing a fair few track days recently, though I don't think anyone would have caught the wear and tear, it's one of those things I guess.

What do you guys think? Shrick cams etc and associated bits to fit or stick with standard cams?

Lets discuss

Pooky has had the same problem as you and his car is at elms.

BMW have had issues sourcing cams and have looked at new supplier bearing in mind the design is probably 12-13 years old.

I thought the CSL cams were a higher lift on the in and exhaust.

would the shricks really give you any more? you would probably need head work and a re map to make them work and that would be lots of £££.

the CSL air intake and head was already reworked extensively so maybe just get it back to OEM and enjoy it?

I think the CSL cams are higher lift than normal M3 ones yes.

Yes, that is also correct on the supply on them, just spoken to my local BMW dealer, availability for CSL cams is now week 9/14 as had major supply problems.

Just been on the phone to Simpsons, they say to change them to Schrick 288/280 12.5mm lift (not 14mm lift as need new pistons with those) with DLC coated rockers as they need replacing anyway, anyone had experience of these?

CSL exhaust cam is different.

Intake is the same as standard M3.

CSL Exhaust cams have been out of stock since May last year, now due March (although I'm still assuming they'll be late).

Yeah thats what my guy at Vines said, he said they are expecting them to be available week 9/14 but thats an approximate date.

Does anyone know what the cam lift/ duration is on the CSL?
