3.3 and 3.8 V6's, MUST READ FOR ALL!
I looked at the service bulliten and all that it says is if the camshaft bearings are worn then replace the short block as the cam bearings are only serviced in a short block assembly. It is for information only and is not an authorization to replace a short block.
My original statement stands as a truth as to how the system works. I don't care if you believe it or not, your reasoning doesn't change the facts.
Glad you got it fixed.
