If your power valve does happen to be the problem, (blown), install a vacuum check valve in the vacuum hose that supplies it. A lot of times these...
yeah... valves is what I'd check out. Have you had the valve cover off yet? Look for loose or bad rockers, bent pushrods, broken springs, etc.

I wonder if you could have another problem causing your pumps to go out. In my experience, mechanical pumps outlast electric ones. Perhaps there...
The 401 is the best V8 AMC made although not as common as the others. It has a forged steel crankshaft and very strong rods. Go hunting for the...
My O2 measures about 18mm; so smaller than the hole I need plugged. I found a 22mm x 1.5 stainless plug on Amazon and ordered it. I think it's...
Main reason for the EGR delete/plug problem to begin with, is because I replaced the factory intake with a non-EGR Offenhauser, but I'm not using...
No worries ... that plug in the pic looks like it could do the trick. I'm currently using the original fitting with tube sawed off and flattened...
You get a few more cubic inches if you put the 258 crank in the 4.0 block. I'm not sure, but I think that combo requires that you use the head...
The fitting threads were damaged, but not the exhaust manifold threads. So I took the other end out of the intake, without damage, then cut the...
My `85 CJ7 with a 4.2 six cylinder has a tube that goes between the exhaust and intake manifold to supply exhaust gas to the EGR valve. I'm...
The Offy intake apparently accepts a four barrel Holley or a Carter AFB style four barrel so the 2150 will definitely require an adapter. I've...
More research tells me the Offy has a square Holley four barrel pattern and a second pattern which I guess is for the Edelbrock carbs. The...
Anyone have one to sell?
An earlier post regarding a 2150 carb swap got me thinking about doing the same thing. I scored a super clean 2150 off of a `87 Wagoneer for $20....
If you have the cash, I recommend a hydraulic roller ground for low end power. It will cost way more because a roller cam and lifters just do, and...
That adapter looks similar to what's on my `85 CJ7 4.2 with a Weber, except my adapter is actually two. Not sure why Weber did it that way but...
sounds like you have it under control
It's been my experience that most external or inline pumps don't need a return unless you're running a pretty high performance unit. It's also...
