Usually if the guides have been bad for a while you'll get wear to the gears asa well. Could be from bad tensioners. Might as well do the whole job and not just the guides. Mine were bad too, especially the driver side. So with the timing chain off my indie showed me it had cause visible wear to the teeth on the upper gear for the cam, and that also had been causing minor damage to the whole driver side head by it being driven when the tensioners and guides were bad. Not sure about the exact parts but I do have the printout showing the whole job with parts if you need it I'll find it and take a pic. Lmk.

I operated to drop in a new motor rather than deal with all the repairs. But I still have the work order from when it was diagnosed.

JEPC shows different P/N's for LH and RH chain guides:



The rotating arrow symbol shows a change from VIN V58603. It usually means the updated parts also fit the earlier VIN range.

I'm hoping the can years are not affected. But If you have this part number let me know. I can budget in this replacement. At the same time I am replacing the fan belts and sparks

though I was told that the tensioner pulley bearing might also be a cause for the ticking.

took a video on the idle. the more i read through forums, the more it seems to be the chain tensioner.

please tell me i am wrong.. took to few workshops and they cannot pin point it. the tensioner replacement needed to see the engine removed and i want to avoid this
