billbuickgs Posted March 16, 2017 Share Posted March 16, 2017 What size and thread type would be correct for a 1956 buick dual exhaust manifolds ? I want to replace the existing studs with new studs or bolts and need the correct thread type for the manifolds Thanks Bill 1 Link to comment Share on other sites More sharing options...
Red Dawn Posted March 16, 2017 Share Posted March 16, 2017 Bill, According to my Shop Manual the thread size is 3/8-16, torqued to 10-15 Ft lbs Mark 1 Link to comment Share on other sites More sharing options...
MrEarl Posted March 17, 2017 Share Posted March 17, 2017 Thanks Mark!!! Bill, were you able to get the studs out without them snapping off. I've never had any problem getting either the nuts off the stud or the nut and stud coming out of the manifold. The latest attempt however resulted in 3 out of 6 breaking off. And how do you deal with getting the broken ones out. Link to comment Share on other sites More sharing options...
billbuickgs Posted March 17, 2017 Author Share Posted March 17, 2017 Thanks Mark, Getting the old ones out is the fun part ! Lamar, WD - 40 ( or others ) , let it set , tapping on both ends of the studs, heat the flange and pray ! If they break , then the my son steps in with the easy -out route !
