Desperate things you did to keep an engine running...

In the mid 90’s I had a ‘77 Ford pickup with a 351M that had a knock develop while four wheeling it. I’m thinking it was a wrist pin as the oil pressure was still ok. I was in the process of building a 460 for it so I needed to keep it running for just a little bit longer as it was my daily driver. I started putting gear oil in it to quiet it up and it did until it got up to temperature, then you’d hear the knock again. I got the new engine done in three weeks and did the engine swap. The 351M was still running, barely, before doing the swap.
