After removing the surge tank and looking (probing) at the space between the block and intake manifold , there is a small
oil mess there. At this time I'll blame myself for not checking the gue better ( front and rear ) . I may have a small void just to the middle above the right coolant pump to block flange. I've cleaned with brake clean and reapplied blue RTV. If that doesn't get it, I'll remove the intake manifold (again) and all that . Another set of gaskets, readjust rockers again, but may have manifold milled a little to make up for previous milling on heads. I have the car up on jack stands in car skates. I have the jack stand supports front on frame tubes at trans and rear swaybar, and tires are about 20" off floor. I can see from under but getting in and out are now compromised. I have to get a step to work over the side.
