First of all, thanks for all the previous help. I have found the final culprit but don't understand why. My passenger side intake manifold bank keeps leaking. I have the Edelbrock Performer intake on the Windsor, but it will start leaking after a few drives. This 79' motor has not been altered except the smog doesn't exist. This is my second Windsor with the same issue with this intake part # (think 2181 from Summit). I replaced the first Edelbrock intake with a new one, ran great, now back to square one with the normal leak. Do you think one of the top brand intakes such as Edelbrock is messing up, (like it is not properly seating), or is there something I am getting. FYI: proper edelbrock gaskets and matching bolt set is on the motor (all new again).
