I have a very slow drip coming down the left side of the block. It appears to be about 1-2 inches back from the front surface of the block.

Anyone had this coolant leak before and know what it is?

Sounds like the TB heater is leaking. Is the top of the Rocker cover wet?

If that isn't it you could be looking at something more serious.

 

I replaced that about a year ago,....but I'll check it. Thanks.

 

Could be the valley pan gasket as well. I experienced a leak at both ends of the intake manifold.

 

Clean the area real good to try and identify. Everything listed above could still be a problem. Doing a radiator pressure test will tell you right away where the issue is.
