Of course no one can say for sure, but, I finally got my car warmed up enough to find that it likes blowing bubbles in the radiator. It wasnt blowing that bad when giving it a lot of gas, it was actually kind of randome blup blup blup's, like one of them old coffee purculaters. Well, I guess that means the 241 heads are a comming off. What are the chances that the block is okay and I just need a set of heads and gaskets and all is fine? Again, nobody can say for sure I know, but, I have no idea what these aluminum blocks can handle.

I am assuming the worst that the heads are fried, would have to be seeing how this car is so ****ed and sure as hell didnt do it when it was cold when I checked for it, but sure hope the block isnt.

Before you tear anything apart. Make sure that it's combustion gasses in the radiator. There's a test kit for that. It could be blub blubbing because the waterpump is weak and the coolant isn't circulating right.
Pull the spark plugs and see if one is cleaner than the others. If one is really clean then it's got coolant in that cylinder.

I guess I will need to do that, but, it is intersting in that you know how you can sometimes hear an intermittent miss in the exhaust? Well, you can "feel" that in the hose as a vibration.

Example exhaust:
normal firing = I
missing = x

so, the engine goes I I I I x I I x x I I I I I x I x ......... randome

The vibration in the hose is like that also but more in a time line like
I I x I I x I I x I x I I x

Cr runs too quiet to hear the exhaust miss and feel the radiator at the same time to see if thier together.
