Well damn. I stripped it down and immediately noticed chunks of rubber laying around the spring for cylinder #1. I pulled the spring and found this...



In case you can't see it, the umbrella seal is shredded. I can push the "mouth" of the seal over the guide if I want too, but it doesn't seem to fit as though it was meant to. If I do that, the inner spring on my valve springs seems to rub against the seal (which is why I didn't put them over the guide in the first place). Perhaps they were shredded because they were loose on the stems?

I have all 12 o-rings but no other umbrella seals. The springs I'm using are the ones from 12bolt.com and I'm nervous they'll touch anything fitted over the guides.

In case there is any confusion, I used these umbrella seals: Howard Cams 11/32 Umbrella Seals and they have exactly the same dimensions as the ones Tlowe referenced in other posts Ebay Viton 11/32 seals
