China wall leak?
I have an oil leak from back of the intake,it leaks pretty bad at idle,question ,would the china wall leak bad at idle? or is it more likely to be the sending unit?Its pretty tight in the back I could not see very well.

When my intake gasket cut loose it was dripping on the cat on the passenger side. People would roll up there windows at stop lights to keep the smoke out.

The corners there on mine have the intake gasket notch meet the head and you've got to be careful with sealant. You can remove the dizzy and clean the area well then goop the heck out of it. I've fixed leaks that way and it does work. Force a good amount in the gap and get some inside the dizzy hole too if you can.
Edit I read your post, it's water? That would be a poorly sealing intake gasket I think.

What exactly would going 50 years back in time to a carb have to do with your intake gasket problem?
No matter what kind of intake you cobble on to it, it still has to be properly prepped, proper materials used, proper installation practices used, or it's still gonna leak.
I have had ONE china wall leak in years of building up SBC's, and it was my fault all the way.

Toss the china wall gaskets and use The Right Stuff on the walls.
Don't just use it in the corners.
Those neoprene seals are notorious leakers.
Torque the manifold bolts in the order in the FSM.
I use acetone to clean every surface spotlessly clean.
I use just a smidgen of RTV sealant around the coolant holes in heads, no where else.

I just fixed a intake leak on my 87 all I used is a thin film of RTV on the intake and Right Stuff on the China Walls make sure you run the Right Stuff up and over the intake gasket where it meets the China Wall. The most important thing is not to move it after you set it on the block, and you have to work quickly before it starts to set.
