Valve seals coming off! Hey guys, I have a 2008 c6 Z51 ls3 vette, I did a cam install and eveyrthing went smooth, after about 500 miles it started smoking, used this forum for advise and pulled off valve covers, found the blue vitton valve seals that came with the texas speed kit to have come off the guides (5 on driver side) (2 on pass side) and got shredded. I know people have had this issue before and replaced it with felpro seals and hadnt had the problem since, just wondering if some one could chime in with some advise, or part number for the felpro seals
A more common issue is the seal actually not properly "grabbing" onto the guide. Ive seen 3 26925kits that customers installed on heads and brought to me. i disassembled to shim and 3 seals were so loose they werent even tight at all on the guide. when i asked them they said they didnt think anything of it. when you've gotta hammer the rest on with a hammer and install tool and 3 just go on right by hand youd imagine they think its odd. only time recently ive seen that. they were the blue us seals iirc. not the brown and black.
I can say i have never actually seen that. I have seen the upper retainer spring pop off, maybe due to guide wear though.

SO NOT TRUE AT ALL.
Springs work better AND last longer when set up to MAX them out
extra seat pressure cant hurt, but the open pressure and .060" from coil bind at max lift just keeps everything in check so the valve ultimately "sees" what the cam lobe is dictating.........
