Hi. Here's a picture of the timing chain system. There are two tensioners that can go bad and cause a ticking type problem. Have seen both go bad at one time or another. I checked for bulletins for this and there are none.
Both, there are two? Did you release the tensioner to apply pressure? Are the guides ok, any broken guide bolts?
I DID REPLACE BOTH TENSIONERS, THE GUIDES ARE ALL IN TACT AND LOOK GOOD, SEEMS AS IF THERE IS NO OIL PRESSURE TO THE RIGHT SIDE, BUT THE OIL PASSAGES ARE SEPERATE TO THE TENSIONERS AND TO THE LIFTERS.
AND YES, I PULLED THE PINS TO RELEASE THE ADJUSTERS.............
The tensioner is not fed by a lube circuit. When you set the timing up and pull the pin for them all should be tight.
