A while ago a discussion revolved around the 2,000 some rubber parts that eventual need replacement. I came across one I never heard mentioned: The hose that lets the waste gate know when to open. Goes from the compressor outlet to the aneroid capsule on the waste gate actuator, kind of hidden under the turbo. When I changed the motor mounts, I noticed the hose was broken at the wastegate connection. Have no idea how long the waste gate was disabled and how important this may be.
