I've had really good results with it... Be sure to post progress picks of how this car turns out...

Well if anyone is fowling my project you know that I have a low cylender, well its the exhaust valve now I have to remove that cam and see if I can free up a stuck (I hope) valve. Has anyone got any input on doing this?

Well I just got the head off, you know that dead rat I found under the hood? well I know what he was eating, there is a bite taken out of the exhaust valve. :-0
Anyway now I know why I didn't have compression on #1 cylinder. Now I have to get a new valve but untell I receve my shop manual, Just how are the valves adjusted? And what would cause the engine to burn a valve? Maybe low octaine gas?

Valves are adjusted with shims that fit over the end of the valve stem, you put the tappet bucket on top of them. It's a big hairy deal getting it right, lots of re-fitting the cams, putting the clamshells on and taking them off. The exhaust valves have pure sodium in them, I can't say I've ever heard of a burned one, but I guess anything's possible.

many things can cause a burnt valve

overheating

the valve not closing tight, this is where the exh. valve gets its cooling. from contact with the seat/head. if sticking open for any reason the valve doesn't get to cool and can overheat and erode, split or fracture a piece off.

most of the cooling of an exhaust valve is through physical contact with the seat and the rest is up the stem and out the guides. Sodium filled valves enhance this up the stem cooling by drawing more of the heat in the valve head away.

So anything that interferes with the cooling process can lead to overheating and failure including bad timing, lean mixtures, vacuum leak causing one cylinder to run lean, pre-ignition, clogged catalytic converter

Thanks for the info, I pulled the valve and it is indeed burned I have a picture and hope that I can attach it here, never done it before, as you see it's a mess the other ones are fine.

Wow..... that's naaaaasteeee.

Looks like it hasn't closed in a decade or more.

**dscottj** · #54 (**permalink**) 11-21-2009, 06:01 PM

Well, dang, dude, there's you're problem...

Whatsitallabout · #55 (**permalink**) 11-22-2009, 04:23 PM

That is true that it's been a decade sence it closed but remember it sat untouched for 7 years and that's good otherwise there might not be a seat and just a nub for a valve.

Need a little help, I am installing new valve stem seals, so far I have been able to get two on and I have wrecked one and the other one isn't cooperating and wants to go no crooked. Is there a trick or special tool to install them?

**86spider** · #57 (**permalink**) 12-03-2009, 06:33 AM

generous amount of lube

slide over valve

push/tap into place with appropriate sized piece of tubing or deep socket and rubber mallet

I did all of that and stilled screwed up two.
So while weighting for more parts to get here I lifted the floor mats, ugh, driver side looks ugly (see photo) right side is still sound. Like most old cars the more you look the more you find.
