Hey guys,

Just wanted to check your opinion on the way my engine sounds. I think I hear the chain rattle, but is there also something else, like piston slap?

Here's the video, I rev it up at 0:18 sec and the sound changes a little:
(My supercharger is off the car right now.)

Thank you!

 

yes, that sounds bad.

It does sound a lot like piston slap to me, but you should at a min pull the valve cover and check the cams for excessive wear. Thats an easy check.
