I was winterizing the Cobalt this evening. I pulled all the plugs (all looked really good), and proceeded to crank the engine while spraying the oil into the carb. I then sprayed a little more into each plug hole, when to my horror, I found a little bit of water on the head, under the hole for #7. Sure enough, in the bilge was 2-3 tablespoons, and a few more drops spit out as I turned the engine over.
This engine has not been run since our last outing three or four weeks ago. At that time, it ran perfectly. I'm guessing the 31 year old manifolds/risers have given up. I had them off recently, so I suppose it's possible I didn't get the riser gaskets on properly, but I've been kind of looking for an excuse to pick up some aluminum exhaust manifolds, and I think this may be a good time. I'm looking at this kit: Dana Marine . Is there something better I should be looking at? Is dry joint that much better? I like the idea of saving some weight while getting away from the old log style manifolds.
I suppose I oughta run a compression check before dropping the money. I haven't done so since last spring (145-150), but I have no reason to suspect a crack. Would a cracked head/block still run ok? Would it necessarily show up in a compression check?
