Okay-Thanks. So if anything was to be leaking from that plug-It would be Oil and not anti-freeze-correct?

Thanks for the quick reply~!
Later Ant

If you are leaking oil from the back of your engine, 99% of the time it's going to be your rear main seal on the crank.

Or between the lower intake and the block, if you've recently messed with it.

Any possibility that the pipes/hoses that run under the upper plenum of the intake for you heater core are leaking, pooling, then running down the back of the motor?

Heater core hoses are tight, brand new. Im runnign a cobra upper/lower-So no EGR hoses to lower. My heater core would be leaking-If it were from the front firewall onto the passenger side header, thats nto leaking.
there really isnt much esle-besides leaky lower manifold or head... Im putting my $$$ on the manifold.
Whatta ya think???

Dude-

let me ask you,, Was it whereabout the head meets the lower intake mani?
or from the head to block???

because-it seems to stop leaking once the car gets hot, actually-doesnt leak at all. When its cold and first started-It drips.

hit mer back,
Thanks Ant

There is a freeze plug in the back of each head just like in the front of each head. They do rot out. If you're in a pinch you can just knock the old plug out and put a rubber expandable plug in it until you can make proper repairs.

Don't know if you got my reply but mine was coming from where the head and block are. Mine only had a problem when the radiator was higher then the back of the block. When i removed the head it was the back head bolt was rusted to crap and made a leak in the head gasket.

hey i got your reply, Thanks. As for my case-The AFR165's are like 1 1/2 years old, I got the heavy duty severe graphite H/G's on there which are also 1 1/2 years old and all ARP hardware for the heads. The bitch is leaking from the rear main seal area, popping out the tranny case-where it meets the engine. its a small drip until it gets hot-then completely stops. I was thinking mani.... But im not sure anymore!!!!!!!!
