Zitat:Original von V8-Mike
Das nennt sich "piston slap" und sollte hier eig. unter den LS1/LS6-Besitzern bekannt sein !?
Mein Ex 99'er LS1 war ruhig, mein 04'er LS6 hat es ganz leicht.

Was natürlich nicht heißt, dass nicht irgendein Schaden vorliegen kann.

Jup, entspricht genau der Beschreibung bei mir.
Zitat:My ss has lots of piston slap. It takes a long time after start up for it to quiet down. When weather is cold the more noise it makes.
Zitat:Piston slap is not the hydralic lifters tapping. That noise is called the hydralic lifters tapping. Piston slap is where the piston actually rocks in its bore (like a rocking chair) until the temperature of the cylinder (piston and wall mainly) reach operating temperature as which point they expand to correct tolerances and it quits rocking in the bore. It almost sounds like a rod is knocking. The tapping noise (light sounding, not a lower toned tap) is just the lifter to pushrod, or pushrod to rocker arm or rocker arm to valve stem being out of adjustment. Neither of which are a huge deal, but should be repaired as soon as possible in my opinion. But the piston slap probably doesn't need to be worried about until an overhaul or the engine fails. Just my .02 cents.
