Weird Coolant Leak


Recommended Posts

1971 240 with SU's/header -- Coolant Water mist sprays out between my intake manifold and head -- Weird. A bit of acceleration and it becomes a little geyser. It is betwwen the number 4 exhaust and intake runners and has actually made a hole in my manifold gasket. Could it be a leak inside the intake manifold? There is a water passage there. Please help!!! Thanks!!!

Thanks for the reply.

Actually there is a water passage that travels through the intake manifold on the early z's. It passes right inside the carb mounts. I am trying to rule out everything possible befor pulling the head.

From your description it sounds like a cracked head or a breach in a coolant passage within the head to the exterior. Again based on your description, this does not sound like somewhere you should be seeing a coolant leak. It may be time to take it to a mechanic familiar with the Z for a second opinion unless you're up for tearing into this yourself to investigate.

Pictures could be helpful.

The coolant passage you speak of only runs near the carbs, never gets close to the head. I suspect a cracked head also.
