I wonder how many of you have the drain on the lower left rear side of the engine on a 235 or 261 motor or is the hole filled with a sealed bolt(like mine). I'd like to hear your experiances with the drain and where you found it(parts supplier) as I've checked the usual chevy parts links and haven't found that drain with the metal piece through it any where.
I have a bolt in my motor block and it doesn't leak but wonder if I should get the parts and actually use that drain on the fire truck. Thoughts or ideas? Thanks.
