I will have to remove my exhaust manifold & have been soaking the nuts every day for the last 2 days(Twice yesterday)with PB Blaster.I intend to do this until the replacement part arrives.I also have special wrenches from Sears that really grip the nut (No socket play) & a "Gator grip" that seems effective.So far one nut has been "Cracked" but I am still soaking it just to be sure.I have not tried to crack or turn any of the other 7 nuts.The car is an '82 244DL w/ 185K miles & the fact that the manifold nuts have never been loosened in 27+ years makes me nevious as I do no want to strip/break any studs.I have not had good luck with studs & nuts in the past.Any other advice from your experience is appreciated.
