If you have the 4.3L, the LIM gasket will fail, typically starting at 80k miles. Have you replaced the LIM gasket? Usually it is a slow like, and sometimes a LIM gasket failure will result in coolant seeping into your oil.
A coolant pressure tester is a solid tool to pinpoint a coolant leak- but a visual of the LIM gasket and water pump are two super high failure points for coolant on the 4.3L engine.

His leaked pretty close to where mine started leaking on my 2002 S10 a couple months ago.
If your doing it yourself, get this kit...
Felpro MS98002T
These are the newer upgraded gaskets that should outlast the truck itself.
