o'ring shouldn't protrude more then .010" above the block deck, but I've been measuring as high as .016".
Can you guys share your experience in installing copper o'rings?
Thnaks!
Ok, back to your original concern. As Greg mentioned, your o-rings should only be about .006 above the deck surface. Sounds like the block was either resurfaced again after if was o-ringed at some point, or they didn't cut the grooves deep enough to start with.
