I noticed that the Venolia pistons do not have oil holes drilled in them to oil the pins, like the stock ones do. Is this not a problem, or should I just drill the two 10/64" holes in the same location as the Opels? I can't see what added the holes could hurt, as long as I don't scar anything up while drilling.
Opinions wanted!
Thanks,
James

Okay, I have drilled the pistons...straight forward, nothing fancy. Then it hit me that I have seen rods in the past that were also drilled with a small oil hole in the small end to help feed the pin. I'm assuming this wasn't needed with the Opel piston because it was a pressed fit. But with the Venolia pin floating, will this be a problem? So should I have the machine shop drill a hole in the rod?
