took some pics of the valve cover. it looks like a few of the lifters have been shooting some nasty stuff up through the push rods. don't mind the grass i washed it off.

Yup, thats a lifter. Im in the exact same boat as you are right now. Im in the process of replacing them with the LS7 lifters.

last two replies. https://ls1tech.com/forums/generatio...head-area.html did you ever find a part number for ls1 size 5 layer gaskets?
the only good thing here is i think i have a blown head gasket on that side any way. the block is wet and the reservoir is almost empty. now if i can just get my ls6 heads finished.
i was ready where some one was talking about weak valve springs can cause the lifters to go. would ls6 springs with 10psi be considered weak?

ok so i ordered new lifters, patriot gold springs, arp studs, and gm 3 layer gaskets. got the even bank lifters out. how can you tell if they are bad? they all look the same. i took some apart. one that i think is bad and one i think is good. the "bad" one had about half the amount of oil as the "good" one inside it. i can't squish any of them by just using my finger while they are completely together.
