Thanks -Ja <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

I haven't noticed any oil consumption problems with my ls1 as of yet. It's an 00 WS6 with 29k miles.

first motor had fairly bad piston slap that would go away on warm-up
it was recently replaced with a 2002 motor under warranty due to the #1 cylinder trashing itself. New motor has moderate piston slap that is gone by 190'

Less than 1 quart in 3000 miles for me and, no piston slap, just valvetrain noise on start up(since cam and springs).

My 2001 LS1 uses oil like there is no tomorrow! No piston slap, though. All stock internals, no headers, just the way I drive I guess. <img border="0" alt="[evil]" title="" src="graemlins/gr_devil.gif" />
