Does anyone have access to a LQ4 piston right now where they can take a measurement for me? I'm wanting to know the depth of the piston dish on a LQ4 piston. I know it's roughly a 6cc dish but what I'm wanting to know is from the top of the piston to the bottom of the piston dish, how deep is the dish? If someone could measure that for me, I would be greatly appreciative. I'm just trying to figure out on paper some PTV measurements. Thanks in advance!

 

i got between .050 and .060 depending on how and where i measured.

 

also know the valve still hit on the ledge of the dish...so don't simply subtract that measurement that was given...treat the piston as a flat top
