Thanx Phil, just the info I was looking for. Thanx for all the help list members.

I've not found it helpful to remove the airbox top (might take off the hose
between turbo and airbox), however removal of Michelin Man hose is
certainly suggested. When replacing the bypass valve, make certain that the
vac hose is in good condition. That hose gets cooked and becomes brittle
from turbo/exhaust heat; it usually splits and falls apart beneath the
heatshield. Remove the intake heatshield and have a good look. If it needs
replacing, consider using a length of copper tubing instead of rubber hose
for the section running beneath the heatshield--or simply use a longer vac
hose and reroute it away from the engine--e.g., along the inside of the
fender behind the airbox in order to avoid turbo/exhaust heat altogether.

Take care not to install the new BPV backwards (easy to do since both its
hose nipples are same diameter)--the small vac/pressure hose should face
