Quieting Piston Slap? Ok, let me start with YES I DID A SEARCH.
Now, is there anything that can be done to quiet piston slap down, because my tapping noise is retarded loud. I read a thicker oil, but no one said anything about what weight? I think I'm using 5w-30.
Anything else? I'm doing my exhaust so it will help cover up the noise (hopefully not make it louder).

I did have SOME piston slap until I switched to 10w30 oil. It has gotten significantly quieter and there's absolutely NOTHING wrong with the car engine wise. Maybe give that a try?

I run 10W30 year round and it's still pretty loud so I don't think there's a "quick fix" for it. My car does have nearly 63,000 miles and never any major problems so it's not a big concern either.

I actually swapped to NON synthetic 10w40 oil and it has gotten a LOT quieter...With Mobil 1 5w30 it sounded like it was trying to come apart or something (when cold started)...very nerve racking IMO.

There is no fix.Period.
Its just the way the pistons are made.
I even had updated pistons put in by GM and still the same. Some cars a quieter than others.
If it made noise while at 200* I would be worried.
I'm using 0w30 for superior start up protection and best protection when at operating temp.

I dont think you under stand piston rattle vs valve train noise. if a piston rattles for a long period of time it will make its self worse. meaning it will crack. there is some much heat ontop of a piston that different viscosity's of oil will not help. LOL

well run mobil 5w-30 like the foctory recomends, and if it is a loose piston, they usually warm up in about the first 30 to 45 secods and stop rattleing. If it is valve train noise i guess ur stuck with it. millions of cars have it and they are still ticking.
