Trucks been home a week and i wanted to clean off some Of the engine as i was wiping a bolt fell off in my hand. Pic below. Go easy on me my Dad was the brains of this restoration when i started. He passed away so your the next best thing! What is this hole? I looked at diagrams maybe a drain? Its not leaking but what do i do next! Thank you! I circles the hole in my pic!
I used a straightened coat hanger to dig out mine. It was full of crud. I then pressure washed that hole to break it loose even more. I, however, was doing a full rebuild and hot tanked the block soon after. You probably don’t want that crap making its way into the water pump. Flush it. Lots.
Clean the hole out with a 20 gauge shotgun brush in a drill motor and chase the threads with a 1/4" pipe tap. Install a new pipe plug with a dab of Permatex #3 sealer on it and you're good to go for another 50-something years. Jerry
The murder victim was drowned in a bathtub full of Rice Krispies and milk. The coroner blamed the crime on a cereal killer!
Cringe and wail in fear, Eloi- - - - -we Morlocks are on the hunt!
A word of caution, I cracked a head on a 42' 216. the # 1. The temp gauge was not getting any water to it. For some reason the older 216's have this problem with flow if the water jacket is not flushed before starting up. A lot of folks didn't run anti freeze I suppose. You probably need to ask the folks here, the 235, 261's have larger jackets. Doc.
