Hi Blindtoe.., welcome..!!
Not a lot to go on here...?
By "clutch cover" ... assume you mean the bell housing...?
By "can't feel it".., do you mean can't feel the hole/source of leak..? Can you feel "wet " when reaching
behind the engine..? Use a small mirror & flashlight to see back there.
Some heads have a soft plug back there that can rot out. The head gasket can leak back there as well.
Engine blocks have a soft plug on the back but usually under the bell housing.
The intake can leak where it bolts to the head also.
BTW., did the eng. overheat.., i.e. did that precipitate the purchase of radiator & hoses..?
