I got as much done today as I could. Passenger side valve covers which were obviously leaking. Changed all the coolant lines I could & completed the coolant bypass. Used the spring clamps from under the plenum instead of the cheap screw clamps they used when the swap was done. Replaced all the vacuum lines I could & installed new clamps. Tightened everything I could reach. It was all needed as everything was well past its service life. Car seemed to run well before so fingers crossed it still does after all this.
