I was going to adjust the valves on my 70 240 I bought last year. As a matter of course I checked the compression at the same time. The first 5 cylinders were 185 to 187 psi at a warm to touch engine. Number 6 was 160+ and the plug was white. Number 6 is obviously running too hot. No oil in the water or water in the oil. I did a variation of a leak down test and air came out number 4 plug hole. It doesn't appear to be a head gasket (or at least the typical failure), but I am not sure what it is. The valves did not seem really screwed up. Anyone have any ideas? I would really appreciate it.

Thanks for the feedback on the T-C Rod Kit. I have discovered I have little strut action in the front. I can barely get the car to move. I know the previous owner had a garage completely go through the suspension and steering. It looks like they possibly missed the struts. The rear is loose and the front barely moves.

I bought a 70 240 that the previous owner had installed a Black Dragon Performance Tension/Compression Rod Kit. Does anyone have any experience with this kit? I don't believe it allows the suspension to move properly. Any help would be great.
