Default Best way to fix MINOR antifreeze leak

Got my new Dart Little M combo together and I have a very small coolant leak that I can't trace down. When I say small I mean I will have 1 or 2 drops of coolant on the garage floor after driving it. There will be a drop on the flat pad by the oil filter.

I have tried and tried to track it down using clean paper towels, etc. and I can't find a trail. I assume maybe one of the rear freeze plugs? But the towel always comes out dry when I wipe around the back of the block.

Anyway, with something this minor I am hoping one of the "fixes in a bottle" work rather than pull the motor.

What is a good one that will work if I already have antifreeze in there? I have seen:
GM seal tablets
Blue Devil
morosso ceramic
K&W block sealer


Thanks!

I personally have used the acdelco seal tablets and they worked really well for me. And i used them on an all original 67 chevelle that was leaking through the manifold and it stopped the leak right away.

Bars leak always stops head studs leaking on stock block builds for us budget guys.

Bars leak fixed a freeze plug for me that was between the block and trans on an import engine, took care of the leaky studs too on the sbc.

For a "good size" leak, I use Irontight. To me it always seals well. It did do better then the GM tabs, but the tabs you can just keep around.

Also for a leak like your talking, about 1/2 - 3/4 teaspoon of common black pepper, YES OFF THE KITCHEN TABLE black pepper into a warm rad will stop that leak.

I honestly think you should keep looking for the leak.

I agree, but I am thinking it is one of the rear freeze plugs and it's not worth the effort of pulling the motor back out IMO. It's not coming from any other source that I can easily see. Not from the heads, radiator hoses, water pump, intake....nothing. It's just one drop alway on the flat pad right beside the oil filter.

The only knock I have seen on the GM pills is they may hurt the water pump. Is that true?

Put some tracer dye in the radiator, put a black light on it. Should help you see where its coming from.

petro cooling system sealant is mostly what we use in a pinch and it works great.

Instead of pepper I use franks red hot... I put that shit on everything. Jk

I have used the tablets also with luck. But like someone already suggested put uv tracer die in it and a blacklight you WILL see where its coming from.
