do you still notice the piston slap now ?
I would say it’s either unchanged or slightly quieter. The only time I ever hear it is in 1st gear when it’s cold the 1-2 shift is at like 2500 and it’s under almost no load. Once it gets into 2nd the load increases and it goes away. I usually only hear it once a day, and it could pretty easily be tuned out if I decided to by just lowering the cold 1-2 shift point.

I did switch to pennzoil euro 5w40 at the first change fwiw
