buick 3.8 V6 ...bad lifters ?

hello all,
99 Camaro, with the subject motor, 84K miles, religiously maintained
this just started happening to me -- when started up, very loud tapping
noise, ala stuck lifter or valve
after 15 minutes of running, the noise gradually diminishes, then is gone
all throughout, factory oil pressure gauge reads its usual psi, car runs like it always has
carbon rap ? piston slap ? recommendations please...
(bummed out, really like this auto)

If it were mine, I would try to figure out what is causing the noise and then proceed from there.

I don't know how to proceed with figuring out what is causing the noise, that's why I posted here

Is it more like a ticking sound or a heavier sound. A lifter makes more of a light ticking sound and piston slap is a heavier spound (almost like a knock). If it's a lifter, you may have varnish deposits on a lifter. It could also be a piece of dirt that is floating around the lifter and, occasionally, gets stuck in it. Either way, you can probably live with it as long as it goes away after the engine has been operating for a short while. If it's piston slap, it could be serious (or not) but you might want to get it checked by a knowledgeable mechanic. I had the same problem in one of my vehicles recently and it cleared up by itself.

In case the engine is a little varnished, I might try adding some formulation like Mystery Marvel Oil to the crankcase a couple of hundred miles before I wanted to change the oil next. Read the instructions and dont overfill.
Then see if the click changes as you drive it. Some people have had this work pretty well. I don't think it will hurt anything, in any case. I have seen it done lots of times, and have done it myself once or twice, and there have never been any negative consequences.
If this doesn't help, then you will have to look deeper into the engine.

What oil filter are you using? FRAM's are known for this.

To the OP... If it turns out to be an oil filter problem, I wish you would please post it here. It would be important to have a documentable case of these claims.

this may or may not be coincidental, but previously I had been using Purolator "Premium Plus" oil filters, exclusively.... then, on a lark, I decided to try the Purolator "Pure One" oil filter -- within 1000 miles of that oil change is when the symptom arose

I doubt that it means anyhing. I used the "Pure One" filter for years on several of my vehicles and never had a problem.

I used Fram for years, because they were so readily available, and never had a problem. All the bad press (and I admit that Fram has dubious manufacturing methods and materials) has convinced me to change to a different brand now, but it had nothing to do with Fram failures.
I want to hear of actual failures, not hearsay based on cutting filter bodies apart.

I've never heard of any actual failures of Fram filters causing problems but I have heard that the filters are not well made. I used Fram for many years and I also used Lee filters - had no problems with either except that on the Fram with the black gripping surface, the engine heat would blster and peel the plastic off.
