Is the 150 dollar bill worth it? Would I need an external oil-cooler for sure since the oil would be hotter than normal without piston squirters?

I've never seen the rod notch in person and I'm doubtful it's effective at squirting. Here's a pic or real Porsche squirters installing in a Type 1 case. Thanks for bringing this up. I'm gonna pursue it for my 2270

QUOTE(McMark @ Oct 26 2014, 10:58 AM)  I've never seen the rod notch in person and I'm doubtful it's effective at squirting. It's detailed in a VW tech bulletin, one (of several) that also recommend elimination of the aluminum/copper head gaskets. A copy here; http://www.ratwell.com/mirror/www.dolphins...m/techbull.html I don't know why they wouldn't work. Pretty straightforward, cheap, easy to do, won't clog, shouldn't affect oil pressure and they'll be slinging oil as long as you have it. Nothing really to lose, I don't see a down side. It's neat to see these old threads come up again with names that haven't been around for a while. Like old friends showing up. |

Pretty straightforward, cheap, easy to do, won't clog, shouldn't affect oil pressure and they'll be slinging oil as long as you have it. Nothing really to lose, I don't see a down side. Oil pressure is based on a certain amount of restriction in the system. The more restriction, the higher the oil pressure. And the opposite is true. So if you notch your rods, you're adding a drain to the system and it will lower oil pressure somewhat. BUT if VW recommended it, there is a certain amount of confidence about doing the mod. But my armchair-engineering makes me think that a V notch in the rod isn't an effective 'squirter' since I don't see how it could squirt. It'll throw more oil at the piston in a sloppy, brute-force manner. I think a true squirter, aimed correctly and which shuts itself off when oil pressure is low is a much better approach. |
