Intake manifold was leaking oil on the ends so decided to replace the gasket. Used Fel-Pro gaskets with the end seals and sealant where the heads meet the block and around the water passages. Everything went back together fine so changed the oil and went for a short drive. Noticed there was some coolant coming out of the corners at the front of the manifold so checked the oil and its a milkshake, tons of coolant/water in oil.
What could have gone wrong here? I know most people dont use the rubber end seals, but theyre actually not leaking at all. I know the gasket didnt shift during install because I used 4 studs to keep it in place. Car s 100k mile bone stock car, no aftermarket head or intake. My best guess is the seal around the water passages. I used sealant there on both sides of the gasket so would think it would be OK.
Going to tear it back apart when I have some time, just looking for some opinions on what could have went wrong here. Have replaced manifold gaskets more than a few times and never had this problem, very frustrating. Any input appreciated.
