The old joke is that FEs leak. They leak
oil, they leak coolant, they leak gas -- yeah, the joke is true, for the most part. It's taken me 20 years to get my Cobra to the point where I would say she really doesn't leak anymore. But I still get down on all fours and peek under her with a flashlight every week, even during the winter months when she doesn't move. Because, she has been known to spring a leak while sitting in her heated garage in the middle of February. No brown
oil, no green coolant, no blue brake or clutch fluid, no red transmission drips, no Moroso climbing lube drips, and no golden gas puddles -- that one I usually smell before I even start to look. When I see nothing but dry cement floor under her it's a blessing.
More than once, I've looked down at the garage floor only to see drips of red blood. Usually it was the result of slicing a finger or arm up and never even knowing it. No big deal, just look around, see where you're bleeding from and just bandage it up. That's the nice thing about external leaks, whether they're from you or your Cobra, they're pretty easy to spot. Internal leaks, not so much. I don't know of any easier way to check for internal leaks in an FE equipped Cobra than an
oil test. And dumping gas, coolant or water in to your oil is pretty high on the shi* list with FEs or any other engine for that matter. Why you wouldn't test for that is just something I can't even fathom and why anyone would even argue against it with our lightly driven, and sometimes very expensive, Cobras and their engines is just beyond me.
