I recently pulled my motor to swap with a rebuilt stock shortblock. When I removed the lower intake I found that antifreeze must have been making its way into the intake of the heads. I know this is common problem when not sealed properly. What type of affect would this cause when running??? I dont see any damage?? I had alot of driveability problems recently and wondered if this had anything to with it?? The engine also had poor compression numbers throughout all cylinders and a one was very low, around 95 or so. I am too far along to turn back now. Hopefully I can fix that with the new install.
