PROBLEM need advice on oil leak

[case_bt]

on my intake manifold I have oil sitting in the gallery were the bolts fasten it to the head the back of the intake seems to be caked with oil.

I have wiped the oil out of the galleries before and it seems to come back after i drive for a while.

It seems to me that I need to change out the intake gaskets
I also get an oil leak on the ground it does'nt seem to be coming from the rear main because It looked good when I had the tranny rebuilt I think it is coming out the back of the intake.

any suggestions
