Ken, What is that brown coating on the metal in your picture? Some sort of plating not used in California? :) I'm pleased that you found the leak and that hopefully the PickNPull yard didn't beat up up to badly when they made you buy that car.

Among other minor problems (ball joints, carb, brake cable, etc.) was a vacuum leak I couldn't pin down. All the hoses and manifold bolts seemed proper but I could still hear it near the carb. Spraying fluids around there didn't make any change. I'd noticed the power brakes were sometimes hard to use but attributed that to the fact when the engine is cold I have to keep extra throttle on to keep it running and that would reduce the vacuum available to the booster. Today on a whim I decided the check the power brakes and how-about-that the booster is leaking. The engine ran quite differently when the hose to the booster was plugged. So off to PnP for another booster (which still held vacuum after sitting for a few weeks) and all is much better now. The rubber on the booster right where the master cylinder bolts up has a bit missing. It would appear that there is a need to have even this spot leak proof. http://s143.photobucket.com/albums/r122/AMCKenA/?action=view¤t=NC2161.jpg Ken _______________________________________________ AMC-list mailing list AMC-list@xxxxxxxxxxxx http://list.amc-list.com/listinfo.cgi/amc-list-amc-list.com -------------- next part -------------- An HTML attachment was scrubbed...
