After replacing the oilpan seal, the real main seal, the intake manifold seal and what other seals you can think of many times over , I have given up on the leaks and will live with them till I die.
Just put a large pan under the Cobra where I park it to take the
oil drip and that is it. Some cleaning of the bottom every once in a while and all is weel oiled un der the car, so no rusting to worry about..
A Cobra is a beast and marks its territory, right!
