This is to satiate my own curiosity more than anything, but how are the wrist pins (or grudgen pins, as the manual calls them) lubricated? I can't see any oil passages on the con rod or in the rebuild diagram but would be amazed if they didn't get any. Is it just splash from the sump? I'm doing a rebuild on a 4.0 and don't plan on removing the wrist pin (unless there is a very good reason to) as they are an interference fit and I don't have a good way of pressing them out.

 

I do not think there is anything on these it is an old design and basically was oiled buy whatever got in there, they are low horsepower rpm engines. That is how they used to build them, I don't think my OLDS 455 had any wrist pin lubrication either

 

I have not built a single engine that had direct pin lubrication. They have all been splash lubricated. I currently have a 351W, a 1300CC VW, and a 428 Cobra Jet. All that I hand built. Not one has a rod galley.

 

Thanks for the replies- I figured as much but it's always good to ask with all of the knowledge floating around here!
