I have a weeping of oil that appears to be originating between the head and the block right below the #6 plug. There's no sign of oil above that point (valve cover gasket) and it is clearly above were the dipstick mounts to the block. The dipstick always stay properly seated (no blowby forcing the dipstick out of position). The engine runs strong (593 rwhp) and has been this way for the last 35K miles. Any idea what would be the source of this leak?

 

anybody?

 

u might want to try running some of that dye in ur oil.
