Hi, I've searched and read through the the TSBs and How-Tos, but to no avail.

My 2005 NA has an oil leak at what appears to be the front under A/C mounting bolt. The bolt seems to go thru a tab on the A/C and then into the block. The oil drip seems to come from under the bolt head. I've sealed the threads going into the block with Permatex Ultra black and put a copper washer under the bolt head. Some how there is still a drip-drip-drip leak.

What am I missing? Any help is appreciated, thanks.
