Yesterday I decided to take the MH into town to fill the tanks and give it my Monthly 40 minutes of driving. Before I left I looked at the motor and found a few puddles sitting down on the right side of the intake manifold. It was probably a few table spoons in each lower indent. I soaked it up with paper towel. I dint see any cracks or evidence of where it may have come from. There is one fairly new heater hose that runs on that side and connects to the rear. I checked that hose for evidence, looseness of clamps and everything on it was clean and tight. After my in town run I checked and there was no additional anti-freeze puddled. I also checked all hose connections, water pump, etc for signs of seepage and I didn't see anything. The PO installed a new aluminum heavy duty WP from applied this last summer.

I couldn't see evidence of the source of the leak but I'm wondering if this is a symptom that y'all have seen before? Could coolant be seeping out at manifold bolts?

The manifold is aluminum.

Thanks
Mike
