Brant,
Last time I needed one I ordered them from PP, but it took months to get in. I ordered extras, so if you want to stop by tonight or this weekend, I can find them and give you one. In a pinch, you can clean up any burrs and reuse them, but mine seeped very slowly after I did that last time. |

In a pinch, you can clean up any burrs and reuse them, but mine seeped very slowly after I did that last time. NICE OFFER! I re used my old one last night I added yama-bond (Honda bond actually)... it will probably not leak that stuff is awesome but like you I had a slow seep after reusing in the past I thought I had one in my stash. couldn't find it last night any chance you have the part number on the bag of your spares? thanks again for the offer I hope it doesn't take months and months but I think the Honda bond will likely do the trick for now at least I'll leave it and try when I add oil this weekend. just need to get a spare on hand for next time. brant |

Look in the 914 section. There's a much larger one. I have a bunch of copper washers...somewhere...if you don't find the size you need. Post the size and I will check my stash.

Guys if these are difficult to get, I'll order in a crap ton and put them on the site to make it faster to get. Just let me know your experience. We can always machine it it you can't easily get. I suspect they are readily available, but I've been wrong before.

I got a copper washer from European Motorworks. Washer looked a bit thin, but probably so to squash it more easily given the straight screw driver style fastening compromise.

For future reference:
It looks like the size is: 22 x 29 Porsche part number (from PET) N 013 829 3 and the sierra madre link to a good price:crush washer I found them on pelican with that part number an original OEM part, from Germany at $2.50/each I'm waiting to hear back if they are now in stock... or if like Stu experienced... it will take way to long to get I have found some generic ones on the internet of the same size, mostly copper. I would think copper would work great, but I've emailed pelican and waiting to hear back on the original aluminum version. |

Copper will work just fine. The OEM ones were aluminum to keep the cost down.

The OEM are aluminum hollow crush washers.
I have tried the basic Aluminum solid washers and they dont seal as well. Here is a pic of both: (IMG:http://www.914world.com/bbs2/uploads_offsite/i366.photobucket.com-10819-1481995594.1.jpg) So Brant, Even if you order some more (and they take a long time to receive), you can come by and get one from me now and just replace it later. I am in the middle of rebuilding my engine now so I will be needing just one in a week or so. (I currently have three new). I also have 8 of the solid washers. |

Mine leaked with both new copper and aluminum crush washers. More than once. I ditched the washer and made a paper gasket and used gaskacinch on both sides. No more leaks

Agreed
The crush design is much more effective at the low torque the factory wanted (Likely the reason it is a slotted fastener and not a bolt head) Why are you rebuilding your motor? What happened? |

Agreed The crush design is much more effective at the low torque the factory wanted (Likely the reason it is a slotted fastener and not a bolt head) Why are you rebuilding your motor? What happened? I was hearing a noise that sounded like an exhaust leak right at 6200 RPM in the very last race of the year at PPIR. When I got the car home I could not find an obvious source of an exhaust leak and a compression test showed less than 80 PSI on all 4 cylinders. My next suspicion was a head leak because I dont use head gaskets. So I pulled the engine to have a look. I DID find evidence of exhaust leaks at the header stubs and at the head copper gaskets. I did NOT find any evidence of a head leak. What I DID find was that one of my OEM Sodium filled exhaust valves looked to be failing. I had yellow coloration on that valve and in the exhaust stub for one cylinder only. So I had a valve job to replace the exhaust valves with SS and upgraded to dual springs to bring my max RPMs up. The rest of the engine looks perfect inside so I wont even crack the case. I will hone the cylinders, replace the rings, and put it back together. |
