Guest jmillsUT28 Posted September 19, 2014 Share Posted September 19, 2014 Hey guys I have a 1952 Buick Super with the straight 8. It sat in a barn for over 14 years and I just got it running good. Had to install a new radiator, ignition parts and rebuild the carb. But now I am getting a coolant leak on the carburetor side of the engine right under the manifold and the coolant plugs. The leak is not coming from the plugs. I was thinking it could be the head gasket but the head does not go down this far correct? Any ideas?

Guest jmillsUT28 Posted September 19, 2014 Share Posted September 19, 2014 Looks to me that I have a cracked block. Not to happy about that. Link to comment Share on other sites More sharing options...
Guest Straight eight Posted September 19, 2014 Share Posted September 19, 2014 (edited) Looks like a cracked block alright. I had a much smaller leak above your leak area, and was able to weld it with a special welding rod made up of the same material as your block. Not everyone has this rod, and many try to use rods made up with metal that should hold. If you decide to fix, rather than replace with another block, I could try to locate the name of the company representative that sold me the welding rod. This type of welding rod is desirable so the weld can expand and contract with the block, at the same rate of expansion. I had the welding done by a professional welding company.

old-tank Posted September 19, 2014 Share Posted September 19, 2014 Weld, braze, or pin it. In the meantime you can get some use out of it with stop leak (only with a recently rodded radiator that will not plug up). You probably found the reason it was parked. Driving it will help disclose other problems before pulling the engine. Link to comment Share on other sites More sharing options...
