Default Ffff coolant leaking

So I have a pretty sizable coolant leak coming from the back of my engine and in front of the tranny. Does anybody know if there is a coolant line back there or is my suspicion of a leaky freeze plug probably right. Hmm Maby head gasket.

What year???????

LT1 has a "steam" tube running back there
IIRC L98 has a propensity for leaks at the rear of the intake

I have a similar prob w/ my '88 L-98. The leak isn't all that bad...yet.

Does the motor have to come out to fix this?

IIRC just the intake. Can be a bit of a bear on the L98.
Do a search and you'll find lots of help.
My LT1 doesn't have coolant going through it so I don't have the problem.

Damn it's coming from the bell housing so it's probably the freeze plug. Maybe I'll try a sealant as I do not have the time to pull the engine anytime soon.

Try some Bars stop leak for a Temp. fix.It won't clog up anything but the leak.
