I have a cracked crank vent pipe.
In the back of my mind, I remember that there are other parts (pipes, hoses, couplers) that also become questionable.
Preparing to change out the vent pipe: what other parts should I get on hand (2 hour round trip to dealer, and parts stores typically not in stock and 1-3 days delay).

Would you consider a silicone replacement?

It replaces the "vent pipe", that T-piece, the metal pipe that runs around engine to TIP, and will be much easier to work with since it's all one piece and flexible.

If you're just replacing with stock parts, definitely also replace the T-piece. IMO it would be a good time to replace the PCV valve with a Genuine one as well.

+1 on MetalMans recommendations, mine broke twice (the plastic gets brittle and from the engine vibrations eventually cracks) and finally replaced it with 034's silicone replacement. Been running solid ever since.

yah replace the pcv when you are at it and the breather hose O-ring.

+1 on the 034 one piece silicone replacement, its the only way to go.
