  • Welding on an engine block - plain bearings

    Had a question for you guys. Has anyone heard of if any damage is done to bearings in a car or truck engine/block while welding on it? I have heard that the current can run through the plain bearings leaving them pitted. In my case I was extracting broken exhaust studs in the cylinder head of a truck engine, and removed about 8 studs through welding washers and nuts onto the broken stud. I had the ground placed at the front of the block on the power steering bracket.

    You'll be fine.
    If you had hooked the ground to the crankshaft.....that might have posed a problem
