Hello,
i have aluminium pistons which didn't have oil holes drilled for the wrist pin in my 26 Roadster.
Can someone please post a picture with the aluminium piston with the oil holes drilled?
I am interested in the location of the hole, the number of holes and the diameter.
My intention is to drill the holes for the oil.
Thanks
Markus

Re: Oil holes for wrist pin
It’s actually more important to have the pistons honed to fit the pin. Most T piston pins are way too tight and/or the bores are out of alignment. Correcting that is more important than drilling extra oil holes. If you do drill holes, you will need to somehow de-burr the insides of the holes.
