I am looking for an oil pan for my HD6G . It’s a 1969 344 Buda engine . If not is it possible to weld a patch panel on?

Pan rotted, or something exited leaving a hole? If rusted out it can be repaired but you will need a larger area than the hole covered/replaced. I'm assuming a stamped steel pan on the engine.

Should be Cast as was the one on my 7G.

Seems that is the tractor the gent put a bunch of time and money into and the engine started hammering? It must not have sold for them.

Aluminum, or iron pan if cast? Cast pans are fairly easily repaired with tig welding after removal from the engine and blasted clean. Seen a couple guys try "JB-Weld" type repairs that don't hold up from the thermal expansion and contraction endured and I wouldn't waste time with that type attempt myself.

Most any decent welding shop doing repair work can take care of it easy enough.

Should be Cast steel, not much Iron products out there for LONG time.

If cast steel, easy repair by most anyone that can weld. Still would require a good cleaning/blasting for cleanliness as oil embedded into the pores makes for nasty repairs.....

Same one that developed a knock . A guy drove across the state to check it out . I prewarned him but he wanted to hear it run . She fired right up but shot the connecting rod out .

Unfortunately, my suspicions panned out. So you are stuck with a blown engine now? Should be parts available but the engine will need removed to address the crankshaft damage at the least. Then the gaskets and seals, etc. Easy to get upside down rather quickly with the escalating costs to rebuild an engine these days.

Sorry to hear this but a couple thousand should get decent repairs done with you furnishing most of the labor to have a good tractor. From your photos it looks to be in decent shape before the engine problem.
