5.3 engine noise P-slap?


tcas1355

Question

I have a 2000 Silverado 5.3L. It started to develop some engine noise recently and i'm not sure what it is. I have read some posts about piston slap, and i'm still not sure if that's it. It has a normal "tick" just after I start it. After that, when I am accelerating or just on the gas a little, I can hear a little "tick", a "ping", something. Seems to only do it when i'm driving. Idling is fine, don't hear it then. Any ideas? :cheers:

Sounds like you have osme engine pinging upon light acceleration. Try higher octane gas and see if it disappears.
