So I had a small oil leak at the back of the engine. I finally determined that the leak was coming from between the intake manifold and block in the back drivers side corner. I tried sealing it from the outside with RTV to no avail. So I decided I would pull the intake off over the winter and reseal it. I also had started getting a coolant leak from the cheap water neck I bought at summit. I tried an o ring style as well as a gasket style and couldn't get either to seal. I managed to damage the threads in the intake manifold that attach the water neck. So I ended up painting the original cast iron water neck and repairing the threads in the intake manifold with a couple helicoils, and installing studs.
I got it all back together this Spring, no more leaks at the back of the engine. No more coolant leaks either woohoo!
