I've been driving it for a year with no problems and then BAM! On my first real road trip in her I started overheating and came to find out that the water pump needed to be replaced. Towed it home and made that fix, problem solved... not exactly. Since that overheating I am now getting a terrible metal "clunking" sound when I accelerate and it dumps smoke out the filler tube. Some buddies said I may have spun a rod and that I might need to replace the main bearings and rod bearings. Does this sound right to you guys? Any insight you all can give would be much appreciated. | | | | | Joined: Feb 2004 Posts: 29,805 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,805 | It sounds more like a damaged piston and/or piston rings that have lost their tension due to the overheating. At any rate, it's major overhaul time, so pull the engine out and get busy! This might be a good time to upgrade to a 54-up 235 engine, unless you're determined to keep it bone-stock. It's very close to a bolt-in swap, with only a few minor changes to make.

I had an inline Chrysler 226 that did what your describing, not from overheating once though.

Took the oil pan off last night and there was nothing hanging down or in the bottom of the pan  . The second rod had a lot of left to right motion. Could this be the cause of my noise? I plan on taking the cap off tonight and looking at the bearing. | | | | | Joined: Oct 2010 Posts: 21 New Guy | | New Guy Joined: Oct 2010 Posts: 21 | I have a 1940 216 that is was rebuilt. I would like to find a home for it. I would not go to the 235 Chevy but move to the 230 250 or the 292 motor. I am in So Cal. Thank You Handtight

I can explain it to you but I can't help you understand it.

I started to check the others and they look good. Might only be that one, but at the same time I did find a piston that was sliding up and down with one finger...no good. Think I'm going to pull the engine and take it all apart...ugggg. | | |
