Alright..The old 911 started to smoke like a Cuban left behind. The first thing we did was to pull off the intercooler to inspect the tubing and look for traces of oil. Not only did we find traces of oil. When we set the IC aside, the oil poured from both in and out tubing. at least a cup of oil during the first 24 hrs.
No doubt, at least one of the sources for the excessive smoke was located.
