I've noticed twice now that coolant has kinda just appeared in little drops, maybe a 1/4 teaspoon on my intake. This is twice in a a couple months. I was reading on another thread that this was a sign of the engine going. Is this true? Is this something I should be worried about? I just figured I'd get to it this summer. I'm paranoid.

Oh, btw it's a 90 TII with a reman motor with like 38k on it.

 

Where on your Intake?

Did you check the base of both hose ends to the one following the BAC Valve? Perhaps the top Radiator Hose Is leaking and making It's way down around the Intake?

If you know the routing of the Cooling System, you'll be able to pin point the leak, no problem.

 

your radiator cap could be going bad

 

I doubt with only 38K miles its coolant seals or anything with your engine, but out of curiousity is it a Mazda reman (if so then its 99% most likely NOT the motor). I would think leaky rad cap or something.
