My truck has developed a coolant leak, not exactly sure where yet - but front PS above power steering bracket. So the decision is to do a full timing belt/valve seal service since it's been about 60K miles/2006.

I thought I might look at replacing the original valve lash adjusters with the new design (larger hole) that is said to not tappy-tappy.

I've done a search in forums and in tech section but I cannot find the part number/source for the new adjusters, OEM or aftermarket.

There are several options on RockAuto, EngineTech, DNJ, Sealed Power, but none say if these are the ones with the larger hole.

Help anyone?
