Oh and no matter how new the oil itll still look black after running through these engines.


I think you called it. I pulled off a bunch of stuff and discovered oil up by the thermostat housing. Certainly not coming from a power steering pump. I checked the hex bolts holding on the cover and found them to be finger tight at best. Must have settled in over time. It's Tom's nice aluminum head that in theory won't deform with tight finger tightening. So I tightened them all up and drove it a bit. Still a couple of drips, but not as bad as before. I still have a drip coming from transmission compression fitting that I'm kicking myself about (put the fitting where you can't get to it).

If I need to, I'll do the valve cover when I pull the manifold off to fix the leaking water plugs. (grumble grumble).

Thanks!
