Hello, I have a Chrysler Concorde with a 2.7 engine.I replaced this engine afew months ago because I experienced the exact problem. The problem is the engine has a bad top end tapping, which sounds like no oil is pumping through some of the lifters. It started out doing it off and on with a light tapping and go away. NOW, IT'S all the time.(Do you think it may be the knock sensor?)

No, most likely a valve lifter or oil pressure issue.

New or used motor?

Used motor.I replaced eight valve lifters in the previous motor that I replaced.I first soaked the eight new valve lifers in oil for 48 hrs, before I installed them.I replaced four on each head toward the front of the motor where the tapping sounded to be, hopping that would fix the problem. STARTED the motor and it sounded worse. So I installed the used motor I purchased which only had a 30 day warranty, that was expired by that time I decided to install it. Fired it up and it had a lite off &on tapping. Drove it for appox. Two months and it started tapping bad.
How do I check to see if the motor is getting the correct oil pressure? If the oil pressure is good, whats my next step?
Thank you;
