ok, I'm back from the big Cars & Coffee at the beach (took my other car) and i'm ready to get back into the Cobra. I picked up a stethoscope. Before I get started and heat up the car, I figured I'd try to take videos showing the header gaskets. It does sound like a header gasket leak except I wouldn't expect that noise to go away with more RPM, but maybe.
The first video is from above, front to back of the engine. Cylinder 5 seems to have a little
oil above the header flange, probably from removing the valve cover. MAYBE there's some exhaust soot on the rear side of #8. I'll check the header bolts while it's cold as well.
Video 2 is from underneath and hard to focus, but it looks clean to me.
What's the torque on header bolts in aluminum heads, anyway? I'll check them even though they have lock washers.
Oh, and I'll connect the remove starter switch and crank it with the valve cover off to watch the rockers move before putting that back together.
Any other thoughts on what to do on a cold engine?
