Valve Spring component questions
I disassembled my springs on my #1 cylinder so far. I was unable to find the "oil shedders or shreaders" that everybody says to throw out. Is it in this pic and I'm just missing it?
Upon inspection of my valve stems, I am able to pick up the spring seat on the exhaust valve(see below) but the intake valve appear to have the seal preventing this.
My intake valve seal is the type which has the metal band going around it.
Are any of these I described an "umbrella" seal ?
Is my exhaust valve missing a seal?
Thanks,
Chuck

Thanks for clearing a few things up for me :thumbs:
That piece in my hand is made of all metal..........That's a seal?
In your second photo, it appears that the item between your fingers, is the seal.

Re: Valve Spring component questions (CFI-EFI)
Thanks again guys. I pulled the valve seal off of the intake valve (the one on the right) and after doing so it looked just like the exhaust set-up.
So in conclusion my exhaust valves have no seal. That metal piece in my hand is the spring seat, as my springs where sitting on top of it (and yes the diameter is wide enough for my 1.25" O.D. springs. I will however be putting new valve seals on both my intake and exhaust valves.
All the new parts should be in tomorrow for install.

Re: Valve Spring component questions (chucks88)
My engine was also equipped only with intake seals and NO seals on
exhaust.
I would strongly recommend you ( and I'm talking from my own expeience )
to either put new seals on all valve guides ( intake & exhaust )
or leave oil shedders where they are supposed to be.
When I did my heads and cam I also installed bigger valve springs
and I couldn't put oil shedders back on. I didn't put seals on
exhaust and now I have blue smoke on exhaust with warm engine.
I guess that too much oil gets to valve stem and into combustion
chambers.
It's true that I used old valves and guides but both are in very
good shape ( only 16000 miles on them ) and I had absolutely no
smoke or oil consumption before that.
:chevy
EDIT: I forgot to put in my sig.
