look closely and notice how the charts differ ,theres a reason! do some research


btw heres typical damage, resulting from high heat expanding the rings ,detonation, with the gaps set too tight, or with crappy fuel octane and high heat,until the ends bind and the piston ring grooves or rings at times are busted as a result of the rings expanding,and binding in the bores

think you may have a blown head gasket or cracked heads ETC??
have you tested for a cracked head or block with the reactive dye in the coolant that shows exhaust gasses contamination?
