Problem found. I had to take it in for the technician to find the reason of the knocking. The technician diagnosed that the roller on the bottom of the lifter under cylinder 3 show metal fatigue and the bottom of this lifter is damaged. He said is possible the oil I used created the damaged but have this have to be proved further. I told him to stop the disassemble process before creating a big bill. My options are to remove the camshaft, installed a new timing chain and other parts and flush the engine to clean the metal particles or obtain a remanufactured engine from Mopar and dealer installed.
you probably won't find another Van for $5000 with a new engine, but you have to be ready for things such as it may need a new trans when it reach let say... 200k miles.
have you consider upgrading to a new van?

Just to let you know that I just fixed the P0420 code on my 2005 Dodge Grand Caravan this weekend. I only need to replace the downstream O2 sensor + adding the check engine light eliminator adapter (cost ~ $30 total).
