I am leaking a bit of coolant as well as oil. I can see the coolant is quite low on the motor--as in below the exhaust manifolds. The oil I know is coming from sump--I probably need a new gasket there and would be comfortable changing that out on my next oil change. My question is this, is it possible that where the block and sump meet that there would be coolant coming from there?

 

No. Closest location would be your heads. If your water pump is leaking it could spray all over your sump from driving. I would advise a coolant pressure test, then look for where it's leaking. Your just going to have to get in there and look closer.

 

No, there are no coolant passages in the lower half of the engine.
The coolant flows around the cylinder walls, then up through the heads and out to the radiator, then back into the water pump to start all over again.
If it is leaking from below the exhaust manifolds you will need to figure out if it is coming from somewhere higher up and running down or if it is leaking from a head gasket.
If you clean up the engine and look really close you can tell where the heads mate to the block.
The mating area will be under the exhaust manifolds.

 

Year, model and mileage?

 

Its a DII.

If you want you can send me a PM and we can hook up and I can help you look at it.
Its not like your that far away, or I can come over to your place, hell man, I dont care.

 

head gaskets?

i mean, there isn't much oil pressure in the sump.

if coolant is coming out of the heads, it'll leak down all over the engine.

"below the exhaust manifolds" sounds like a head gasket to me.

 

Do a coolant pressure test, that's the simplest way to see an external leak, since it's a bit safer poking around the engine without it running.

 

First, have you ever done a set of head gaskets before?
Second, don't wait till your next oil change to replace the head gaskets, order them today and get started or your engine may not make it to it's next oil change. especially if the gasket totally fails and you don't catch it in time.
