I have a 68 olds 455 with the Edelbrock performer intake . I just recently noticed a tiny little coolant weeping through where the intake meets the head just in 1 spot . I tightened that bolt and it stopped for a while but now it’s weeping again . When i say weeping I mean there’s like a small drop of coolant there after I drive it for hours . Not sure if I should even worry about it or not. I was thinking about putting a dab of Permatex the right stuff on it but was looking for any tips or tricks . No other spot on the manifold leaks a drop and the cars not burning coolant or anything so I just can’t see how ripping the manifold of is worth it at all . Thanks guys

 

I would keep a careful eye on the oil level. If it's going up, you could be leaking coolant into the oil. The other thing is to drain the oil into a clean pan and look for any coolant in the oil. Leaking at that spot above the manifold is not an issue. However if it's leaking under the manifold, then the coolant is going into your oil, which can cause the engine to seize.

 

If that is truly all that you get then I would stop worrying about it and keep driving. Like sysmg said just check the oil and make sure it isn't getting milky looking. Also, are you absolutely certain it isnt coming from the temperature sender port and running down ? The intake sort of looks like somebody has been grinding on it right there and it doesnt quite cover the gasket. May or may not have anything to do with it.

 

Oil level is holding steady and a perfect golden brown on the dipstick. And that spot you are referring to is from the coolant it ate the paint. And no it’s not coming from temp sender
