Hi, I have a brother who's 2006 4.2L tailblazer ,The lower end of the motor seems to have a rod knock.I wanted to know if a motor out of a 2005 will bolt right in without having to make any changes,Will all the sensors plug in? Any issue with the exhaust? oil pan? ETC...Take out motors for 05's seem to be much cheaper..Thanks for your help...John

No. The 06 motor had a mild redesign. It added things such as a MAF sensor which brought on a slew of programming changes.
If the car is an 06, is it not still under warranty? I haven't heard of these engines having major problems (unless it were a 2002 model), especially if it's so new. There are many sensors that could fail and create what seems to be a larger problem. Get the computer scanned with a TechII unit from a dealer, even if there is no CEL.
