Continental Y91 Manifold Restoration

admin

This is an intake/exhaust manifold off a 4 cyl Y91 Continental that powers my 1948 Onan genset. Cracks visible after magnafluxing and some warpage that is not visible in pics 1 and 2. Next two pics after a little cast iron welding magic.....

Reply:Almost done. No more cracks and gasket surface is nice and flat.  Some minor port work and a coat of manifold paint then ready to start putting it back together.  Attached ImagesMiller LegendMiller XMT 200Miller HF 251DMiller Spoolmatic 30AMillerTrailBlazer 250GLincoln LN 25Lincoln G9 ProLincWelder 225Lincoln Ranger 9Lincoln Ranger 275TJhttp://onanparts.com
