I just went through my engine oil leak problem with an UV leak kit from Napa and found a few small leaks but the biggest one has me confused. It looks like the biggest one is coming from the front of the engine (5.0 liter aka buick 307) in the area just under the intake manifold and right behind where the water pump mounts to.There is also a sending unit there that shows some dye. Is this area the front timing chain cover? and what is that sending unit?(oil pressure?.. I thought that was on the lower drivers side of the block) Any idea's? Would it be possible for the intake to be leaking oil? or is it more likely to be the cover and or sending unit? Any help would be appreciated as well as an idea of how involved this fix would be.(It's not a good thing to be leaving oil spots everywhere I park this nice looking Caddy)
