Ever heard of coolant dripping from the timing chain cover? Almost looks like it could be coming from the crank, behind the harmonic balancer, but maybe more investigating needs to be done. Could it actually leak from a freeze plug behind the cover? Seems like it would drip into the oil pan rather than come out past the crank seal.

Are you sure it is not leaking from above in the water system and then running down to the seam around the front cover and around it to drip off? I think you are correct in your thought about it going into the oil pan if actually from behind the cover.

Could be a freeze plug or the water pump.

I would check the water pump very closely.

The water pump is brand spanking new. Just installed it onto a freshly rebuilt engine. I will look closer with a flashlight to see if it could be running down around the gasket surface where the water pump bolts to the block. I am seeing a little bit actually on the bottom side of the crank, just behind the harmonic balancer. Can't imagine how it would get there unless from behind.

I swear by Permatex Indian Head Shellac for water pumps.

When troubleshooting a new issue, start unwinding events backwards from the most recent work done ...

I have had two incidents with water pumps over the years where brand new (rebuilt) water pump shaft seals were leaking. Actually, it turned out that one didn't even have a seal installed. A lot of labor to find out that the company rebuilding the pumps had zero quality control.

Ditto with the water pump. Rebuilt my 1500 lump and used a new old stock pump, leaked after 150 mile. The next rebuilt pump leaked as soon as it was fitted. Third one has been fine for the last 900 mile, touch wood.

Also can get leaks down the water pump mounting studs if the threads are not sealed in to the water pump housing. Coolant runs down the threads and drips off the nut at the end of the stud.

Good luck in getting it sorted.

If you eliminate the water pump from your enquiries......

there is a core plug (freeze plug) semi-behind the engine front plate on the manifold side. Hope that is not your issue because there's a lot of dismantling to get to it. Also two of the timing chain cover fixings towards the top on the manifold side go through into the water jacket. They should be studs, put in with sealant.

Take out two top left bolts of timing chain cover see if coolant escape from there.
