Re: 356 connecting rod oil hole

Oil squirters are an interesting thing many old engines had the hole in the rod style but for the most part that was fazed out starting in the mid to late 1950s. To the best of my knowledge no major production had them during the muscle car wars when RPM and HP were up. during the late 80s and early 90s the manufactures started to use them once again with a squirter plumbed into the lain oil galleries with a bit of tubing pointed at the bottom side of the piston. The best example would be a mod motor ford (4.6, 5.4 ect) the reasoning behind them is more for piston cooling than cylinder lubrication. Having seen (using one of those tiny cameras) what the oil looks like in an engine while running there is enough getting on the cylinders to keep them well lubed trust me. The trend to include them once again stems from the hotter standard operating temp and higher compression that you find in a modern engine as well as a higher potential RPM. Having said this does a Packard NEED oil squirters? probably not but it wont cause any negatives if you have them
