Timing chain

(2002 Pontiac Grand Am)
in Sellersville, PA on June 14, 2011
This is a 2.2 ecotec. The timing chain tentioner broke. I changed the whole timing set but still have a slap or knocking noise. Thinking the new tentioner isnt doing its job?

I would remove the valve cover and then have someone crank over the engine ( with the spark plugs disconnected but still in their holes ) and watch the chain to what is slapping. I would also pull the fuel pump fuse so you don't flood the engine with gas. I just did this on a 2.2 Saturn ecotec and it worked out very well. I was looking for something different, i.e one of the rocker arms came off.
