Oil leak on front of Engine cover? Help please
Oil leak on front of Engine cover? Help please I was hooking up my AC lines when I seen this oil behind the crankshaft on the engine front cover assembly and the front of the bottom of the oilpan as well as the loom. Well I do not have any problems and it seems to be holding the oil because the oil is not low now but I want to know what the problem is so I do not have a major problem later. Any input would be greatly appreciated

Front timing cover seal. FYI when they are to that point it is usually time for intake and pan gasket's also since it's an lt1. They go forever but stuff seems to start leaking simultaneously. I'd say pull the engine and reseal it no more oil leaks in the driveway. Also be sure to inspect the waterpump real close and make sure it is not leaking onto the opti.

ive had this leak for awile to just couldnt track it down. So is it the front crank seal or timing cover seal? It would make more sense being the front crank seal. Anyway does anyone have and tips on how to replace this seal?
Could be crank seal. Also the bottom of the timing chain cover doesn't have a gasket, but this is pertaining to my LS1 and a 4.3L that I worked on. GM uses ONLY silicone there and the gasket against the block itself. Could be leaking there. It is really easy to replace!!!! Just get a three jaw puller, new crank seal, crank bolt, and TCC cover gasket and you are good to go!!!
