It seems when I search on 986 timing chain guide or ramp replacement I only get instructions on replacing the variocam ramps. It there any good videos or the like for addressing crank to cam timing chain guide replacement?
Thanks in advance

The chai that goes from crank goes to IMS. To change the chain guide in that chain requires the crank case to be taken apart (split). This is much larger job to overtake.
The long chain ramps for the both banks IMS to intake cam can be changed while cams are out by removing one bolt that holds each chain guide. Bank 1 (if I remember the bank correctly) you need to remove the oil pump housing first.
