Default 1991 5.0 oil and coolant leak at rear of motor?????

Couple of questions. First off, my buddy installed a BBK 70mm t.b. and spacer, after starting up, found coolant dripping from the front and rear
of water inlet and outlet for the egr spacer. Look easy maybe loose clamps, well removed hoses and trimmed ends and installed new clamps, restart same thing drip, drip, from the hoses, also found gasket
between t.b. and spacer wet. So now we remove the intake tube to t.b. notice coolant inside t.b., and inside upper intake. Found spot on lower t.b. gasket didn't seal. Installed new gasket cleaned t.b. and upper intake, blocked of hoses to spacer and road test, come back park car saw oil leak and a little coolant spot underneath. Damn the luck right, trace it down to rear of motor, can see puddle of oil and a little bit of coolant on top of the block and running down top of tranny. Could this be just a simple 5.0 rear intake gasket blow out or more? Inspected radiator and oil, no milkshake, no water out exhaust and still runs like a raped ape. Could the t.b. and spacer problem have caused this, or just s***ty luck?

you problaly need to change your oil, this happened to me my tb gasket was too big for my tb so i had water leak into my oil and i had to change it a few times, the way to check is loosen your oil plug to see if water staarts leaking because the water will leak before the oil does if, if you see water dripping drain it all, get some cheap oil or old oil and put it in and then start for a minute then drain it, keep doing this til you see no more water
