    Hey there.
    Just wanted to check with you since you are working with cars more than I am.
    I was wanting to know if the 3.8l in the pontiac is known for lifter tick.
    I have my best friends firebird here that ticks on startup and continues til it gets to 200 deg and sometimes one lifter continues to tick even afterwards. I know that usually this is varnish build up that does it. I've run seafoam oil treatment to get the detergent in there and clean and ran it for about 1000 miles then drained oil today and replaced with castrol edge high mileage. its only got 110k miles on it.
    Castrol edge and wix filter put on and it still ticks on startup cold til it gets to 200 deg.
    As soon as i get by autozone (they are only ones that i found it at) i'm getting some zinc/phosperous additive to add to the oil so that it does a better job of lubricating and cleaning.

    I just thought i would ask you if this is a known issue with that particular engine. thanks

      Not really, any engine can develop a little clearance between the rocker and the valve, or between the valve(s) and the valve guide(s). There are many times that some valve train noise occurs that left undisturbed has no real impact on the engine's operation.
