Exhaust Manifold Repair in Buick - Pre War Posted August 12, 2010 Update on Exhaust Manifold repair and running lean problem.The carburator was rebuilt by Old Carb Doctor in NC, Thr Heat Riser Sleeves were installed by Bill Boyce in NY ( after talking with several local machine shops who lacked confidence in pressing in and out) and the badly cracked Exhaust maifold was welded by Charles Clemont and Ceramic Coated by Tom Sparrow of Prairie Auto in MN and new throttle shaft was carved out of stock by a local machine shop. Every one of these folks were most helpful and all the work (while not inexpense) was super. Would recommend any or all for any work required.Finished assembly of all the components yesterday and she fired up and is running. First road test will be on Sunday (have company all week end). But could not contain my satisfaction and had to report current progress.That old feeling of hearing an engine fire up after disassemby just nevers goes away!TomWith the exception of the heat tube guy, all of my work was done by the exact same people and I totally agree. Expensive, but great work and worth it. If you go cheap on the manifold you'll be doing it over and over again which will end up being more expensive yet. Good luck on your maiden voyage!
