So, I replaced the intake gasket and this darn thing still leaks just the same. I did this based on your thoughts here, plus seeing a potential leak path up above the bellhousing. I am certain that the valve covers and the intake manifold are not the source of the leak. IT drips along the RFOB, seems to run down the dust cover for the converter, more on the right. I can only guess that the only remaining leak source is the rear main seal, right??
