Smoke Under the Hood
I don't have my YJ on the road yet, but I start it in the garage about once a week and let it run for a while. Usually, when I shut it down after letting it run for about 15 mins, I can notice some white smoke coming out from around/under the intake manifold and have a heavy smell of exhaust fumes. I have to assume the smoke is coming from the exhaust manifold beneath the intake, but I can't see from where exactly. Today, I let it run for a bit longer than usual. After about 20 mins or so, the fumes in the garage were fairly strong, so I shut it down and checked out under the hood. The white smoke was coming from the same area, but also from around the water pump. It looked as if it were coming from where the lower radiator hose attaches to the pump (of course that doesn't make any sense to me). I know there is a very slight leak of coolant around the thermostat gasket (PO didn't seal it well).
So, I guess my questions are revolving around the smoke. Has anyone else had these experiences, or know where I should start looking for a solution? There is no smoke coming out of the exhaust pipe, only under the hood. And both locations smoke for several minutes after I shut the engine off. Thanks guys!
