Version 7 of the Owner's Manual says to replace the cambelt at 30,000 miles or 3 years:
FWIW mine was quite knackered at 4 yrs and only 5K miles … had to be replaced!

I dont like the spacers in between the motor housing and the cam cover because of air and rain water.
Unfortunately I dont really see and understand the venting solution on the photos above…did S&S cut some slots into the cam cover…could somebody post detailed photos how the final or actual solution of the vented cam cover is made?
Icould do the job on a milling machine by myself…but I would like to do no mistakes. to me, IMHO (I am not humble but I am opinionated) the vent spacers allow MORE grim, dirt and C@RP into the area! The purpose of the spacers is to vent hot air when the engine is switched off. Due to the nature of the engine it always stops in the same place leading to local hot spots on the cambelt which resulted in a few early cambelt failures but the small vent gap stopped these. The spacers were a quick fix and subsequently the cambelt cover was redesigned by S&S with cooling vents. With the spacers the gap is quite small and does not lead to significant ingress of water or dirt. If you have an early M3W without a vent then using a couple of washers to space out the cover a couple of mm is sufficient and a well proven solution without needing to machine or modify the cambelt cover. One of the reasons I took off the OEM S&S cambelt cover was the venting slits in the cover. I thought they would allow dirt, sand and bugs into that belt area so I replaced it with the clear cover that just has spacers for venting. I have about 4K miles on the belt and it looks fine, and because of the clear cover I can look at the belt without removing anything.
