2000 Discovery II w/Leaking Intake Gasket?

I have a 2000 Discovery II 4.0L. A repair shop said that it was the lower intake manifold gasket. I replaced the lower intake manifold gasket, the valley seals (making sure to put rtv in the corners), the upper intake manifold gasket, the valve cover gaskets, oil separator and the the 2 coolant O-rings. I filled it and as soon as I started it, it immediately started leaking again. Any idea where I went wrong?

Re: 2000 Discovery II w/Leaking Intake Gasket?

I figured it out. When I started the vehicle I could only see coolant gushing out from behind the engine. It turns out that throughout this repair I had to remove and re-install the coolant inlet tube multiple times which caused the o-ring to shear. I only caught this by accident but wanted to let anybody else know what to watch for in the future.
Thanks
