Looking at the stock rods on some 2TG pistons there is an oil squirter hole. I thought it was only the 3TGTE rods that had an oil squirter? I have compared against a 3TGTE rod and it is different as the squirter hole is in a different location on the 3TGTE rod. Do all 2TG rods have the squirter hole but not the 2T?
