Six Pack issues and rebuilding by tommyg29

4 minute(s) of a 193 minute read

Ok, had an hour of time to spend in the garage tonight, so I pulled the manifold (with the center carb on it).

It was heavy. Had to strain to pull it up and off. Getting old. 

I didnt realize the valley pan also served as a defacto gasket. The only sealing material seamed to be a relatively thin line of gray colored silicone type material.

Here are a few pictures. Any comments:

Car has run fairly well for quite a few years now, up until that night a couple months ago. Ever since then  

But at least I think all my issues are from the manifold up, so it shouldnt be that difficult. Right!?  

I doubt the manifold leak is causing my problems too. Probably not that simple. 

When the parts come in next week from summit, I will use the paper gasket beneath the pan, and silicone sealer above.

In the meantime gonna clean up the manifold, make it nice and pretty.

By the way, are these carb gaskets ok, or should I use the ones that have 2 holes?

A few pictures which look disturbing to me for an engine with 7000 miles on it since last gone through, especially the inconsistency of conditions. And now I know why it blows more smoke out the passenger side. #8 in particular seems to sit lower back there where oil is settling. Tried unsuccessfully to get my endoscope snake camera working but these pictures are good enough to give you an idea.

Comments?

PS...these are in order intakes #1 to #8

I always instinctively knew something was amiss with #8, and now I see what. Plugs were always wet when I pulled them, and when the car sits for more than a week or two between starting it, it always would run rough for a couple minutes, and I knew it was from that side.

What do I do here?  

I am as full of questions as I have pictures. How easy is it to replace the seals, set lash, etc. and are my problems bigger than that?
