Hey Folks, I would like to put valve reliefs in some pistons that are already mounted on rods. Does anyone know where to buy these cutting tools that go through the valve guide and spin with a drill to put valve notches in the pistons? Thanks, Lou |

OK, I spoke a little too soon. Here is a tool made by Isky. Kinda salty, but should work. http://www.thunderracing.com/catalog/?a ... 71&sid=455 http://www.iskycams.com/onlinecatalog.html Any other sources? Cheers, Lou |

Relax, Linc.....Those are Dutra-made valve relief cutters. Not Dutra-made-by-accident damaged valves.   Roger |

Doc is not only one with this, I thought of this too because of small budget what to do with the early turbo 2.2 pistons (they're flat tops with 9cc dish). Shop it or do myself with a homemade valve relief cutter for hybrid 16valve head on typical 2.2 or 2.5L block. Cheers, Wizard |

Yeah, that's what I was gonna suggest. Welding a piece of tool steel to an old valve to make cutters.

I've used the Isky tool. It works fine, but it's not super simple to use. There is a collar on the pilot that you have to adjust so one doesn't over cut the piston. If you have a dial indicator and stand to make sure the piston you're cutting is at TDC and feeler gauges for adjusting the pilot collar you're set. It's not tough, just a bit tedious. |

Yes, many of the tools shown are used as 'pocket porting' aids. The photo shows how you can make home made cutters to do many things. DD |

Well, I did this the easy/cheap way. Made relief markings on the piston tops and went to town with my die grinder and a 1/4" cylindrical (no taper or rounded end) carbide burr. 10 min/piston and I have 0.120" deep reliefs in my pistons. Clamped the piston (w/rag) in the vice and used a steady hand. Getting closer to assembling the V motor... Lou |
