school ball drive

[DutchEdwin]

I made it having the car ready for driving my graduated son the his school ball. It was fun, all sorts of vehicles from a chopping cart to a mk2 jaguar and of course US oldies. This event of dropping off the last years students take about 1,5 hours and the drive is about 1 mile. This drive is notorious for old timer engines running hot.

But....I made it...until the last 75 meters. Unfortunately had to shut the engine down with nowhere to go. But heck, what student can say...The principal took me in personally....by pushing the car the last 10 metres:p

He had fun and got good credits for his ride.

But what happened. As the engine is hard to start when hot I let it run all the time. The ride took about 30 minutes as I was 1/3 in front. The temp meter was ok, about 3/4 on total scale. Then the engine started rattling, like tapping of the valves, the hydraulic valves are not getting enough oil I thought.

Also had a light gray plume coming from the front at that moment. I Shut it down immediately after that.

Because the engine was idling all the time the oil pressure was low. After the car cooled for 1 hour, it started right up, the valve rattle stopped after 10 sec. So must have been an oil problem, oil to hot?

Any ideas what is wrong here. I should be able to let the car idle for 1 hour in a traffic jam!

Do you know what the smoke was? Coolant?

[DutchEdwin]

You tell me. Could be the radiator cap venting. When I shut down and looked there was no smoke, damp. And on oil on the side of the engine, or in the coolant or coolant in the oil.

If it was damp, maybe it was just the radiator venting itself. You would have smelled that though, I would think.
