I saw a you tube video where someone was machining offset notches, one on each side.
They both pointed at the piston, just one would be offset to the top some and the other to the bottom. seemed reasonable to me. His mill was set up off center of the rod and he just flipped the rod over to do the other side. Jim |

Interesting to look at the Carrillo rods.
They have a galley going up to the small end of the rod...think about that modification... |

QUOTE(r_towle @ Oct 28 2014, 05:05 PM)  One of the things I saw, which I can't seem to find again, showed a notch on both sides, offset to spray in different directions. So instead of the notch being at 6 o'clock, it was at 7 on one side and 5 on the other side....so it would spray both ways. Doing what you describe would have ZERO effect since the rods are always in motion in relation to the piston. This motion ensures that the spray is constantly moving across the piston crown on both sides. That would only be a factor if the rod stayed in a static position in relation to the piston. |

Carrillo cuts them offset also....figure they might have done a little bit of research, maybe...

QUOTE(aircooledtechguy @ Oct 28 2014, 09:30 AM) directing a portion of that splash where you want it at the piston crown. But I still highly doubt this comes out as a stream. I suspect this increases the amount of oil being slung by the crank, which increases the amount of oil hitting the back of the piston. |

Takes a really long small diameter drill bit if they drilll. Hard to do as small diameter bits have a tendency to bend and wander out of the side on long holes. GE jet engines tried drilling jet engine turbilne blades for cooling ( about the same dril length) and went to long ram Electrical Discharge Machining (EDM) probes to burn passages in the turbine blades. |

If you want threaded squirters you can grab them from any 1.8t engined vw/audi in the scrapyard, I think most turboengined Saab engines had them too, at least from ~1994 and up to 2003.
Here's a pic how they look in a AEB engine (VW Passat/Adui A4 1.8t 150 hp) http://s2.photobucket.com/user/Pitguy/media/audi003.jpg.html |
