DyNoFlow1950

Hi Sledheader, My '50 Model 52, 263 was doing the same thing including the copper gaskets wrinkling up between ports. I torqued them as above several times but they eventually wrinkled over 3/8" partially blocking #7 exhaust. Then I re-read the Buick repair manual several times and it said there are no gaskets on the exhaust manifold. I also have the 1950 Buick Service Bulletin and it says there are no gaskets on the exhaust manifold. Both say to use a mixture of graphite and oil, bolt it right to the head and follow torque instructions. In my case I cut out the intake portions of the non-copper multiple gasket and used those on the intake only. The mounting to the preheater section is adjustable so the intake & exhaust manifolds can seal to slightly separate levels on the head. I have seen an old set of 1940 replacement exhaust gaskets and they were 8 individual rings with inside ridges to hold them on the manifold as you install. I don't think that long manifold was ever supposed to share a common gasket with the intake even though they are sold that way. They just move around at different rates causing the wrinkling. Those little saddles on mine under the mounting bolts have 1/16" clear marks on the insides so that manifold does expand & contract quite a bit. Hope this helps. My dad had a '50 Super for 7 years and I don't remember him ever doing anything to the manifolds.

I bought 2 new rear shock links at Flint recently and was told they are for my 1950 Model 52 Super Sedan. Getting the old ones out, they are 7.5" center to center to each mounting stud. The new ones are 7". It looks like I could install them but the shocks would have .5" less travel. The wheels would not hang down quite as far when the car is on a hoist making the rear tire to fender well clearance a little less. My question is will the shorter links effect the ride of my Buick and will they do any damage to the lever shocks?
