gaskets

[G60michael]

Hi all 60-ers, as I got the manifolds of the 66 to tidy up the block and paint it properly, I needed to removed both intake and exhaust manifold.

Today I purchased the gasket between the manifolds where they bolt to the head to replace when I put it back together, got one from a few guys at the part store cheeap as chips looked like it been there since the 70's but still in a package and good as new.

I now need to hunt up on of those gaskets that goes between the intake and exhausts manifolds where they bolt together and the gaskets in between them. The gasket is a Triangular sort of shape. Does anyone know what tis gaskets called or a Part no: ?

Also what's the little gate device that's in all the exhaust manifold that's got a knobby handle on the outside of the manifold towards the radiator
The one in the 66 is stuck one way, the one of my 77 is also stuck one way, but I pried it and freed it up easily enough. The ones off me 72 moves freely side to side as well as the one in the 78.

So what's right and wrong ?

Any help appreciated

Not really a conclusion because I still get a sputter when at cruise speed and let off the gas but, oh man, is it better.

Dave,
That's a typical sign that you have a leak in your exhaust system. I used to go nuts with it until a friend told me about this condition in any car. A possible culprit could be the shaft of the heat control valve. In the picture it's actually #11. Over the years, wear of this shaft at the wall of the exhaust manifold produces a gap big enough to allow fresh air, that when mixed with unburned fuel, will produce this sputters.

There's no easy fix to the valve itself. In my case, since I was very annoyed by the constant sputter, I welded the shaft in place, at the opened position of the heat control valve. This heat control valve diverts during cold starts, part of the hot exhaust gases to heat the underneath of intake manifold to allow for a better combustion. Rest assured that you won't have any problems. I driven during the winters here in Virginia in 10°F (-12°C) without any problems. Our Patrols are not daily drivers any more to the point that this issue will pose some problems.

What's more, I could bet some money that half of the Patrols of our members have the bimetallic coil spring #12 inoperable, so basically the heat control valve inside is doing nothing!!

Any exhaust leaks at the gasket for the pipe will also cause this.

Dave made his own gasket using this gasket material: http://mr-gasket.com/exhaust-gasket-material-10x10.html Sometime it is necessary to make your own gaskets.
