Question about 1999 GMC Suburban
Common leaks on GM vehicles with oil coolers are at the fittings and where the oil filter spins on is the adapter for the cooler lines. Remove it,clean it and replace the gasket(s) and "O"ring. Only two bolts! Easy but messy fix. Gaskets and "O"ring available from GM dealer or most local parts stores.

Common oil leak on those vehicles is the "quick connects" where the oil lines go into the oil cooler (what i believe you are calling the "doble") replace the o-rings on the quick connects for the lines
