Flathead V8 Welch Plugs

[Bob Moseley (RIP)]

Hi all
Whilst happily working on my flathead the other day I was talking to another restorer mate who expressed surprise when I mentioned the Welch plugs located under the sump cover in the block. He was not aware of these. Probably most of you readers would be but these plugs are a real trap for new players. When water is found in the sump and the owner can’t find any Welch plugs in the block, they often assume its one or both of the head gaskets or something more devastating. BIG TIP – if you have your motor out, remove the sump and check and replace with brass ones. Whilst you are there it is also a good opportunity to check the oil pump.
