Tapping noise in LS1 Posted By: deathofseasonsLS1 On: 05-14-2008 @ 00:57:34 Reply | Edit So recently my motor started having a tapping noise come from it. I thought it could be just a lifter tapping, but normaly it goes away after 20-40 seconds right? Well mine goes on untill it gets to running temp. and even then it still taps a little bit under 1500rpms, anything above that it goes away. Does anyone know what it could possibly be, and have any solutions to it. If it is a lifter tapping would a thicker oil help it any, and if it is a lifter should I replace it or worry about it? I'm running Royal Purple 5w-30 full synthetic, and Lucas Full Synthetic additive. Posted By: Fury_786 On: 05-14-2008 @ 09:07:50 Reply | Top | Edit piston slap its an LS1 thing --

Like Fury said, it's an LS1 thing. It's down right nerve racking hearing it from under the car. The sound resonates through the oil pan. --  Posted By: TransAm64 On: 05-20-2008 @ 00:01:29 Reply | Top | Edit Welcome to the LS1 world....Look @ it this way....it's not a v-6.

Did when I bought my car with 64K miles and at around 100K miles I started using Amsoil 10w-30. With the amsoil I couldnt hear it any more. --

They replaced the whole longblock for a worn out lifter but i didn't care...it was under warranty
