Missing ARP Head Bolt Washer Reuse Stock OEM?

LonnyEnds · 11-18-2011, 01:51 PM

Hey everyone I am halfway through a head gasket job on my 1990 Base Supra. I am using a OEM head gasket and ARP head bolts however ARP shipped me 14 bolts and 13 washers. I am going to try and source a replacement locally today and need the car on the road this weekend. If I can't find one has anyone been in a similar situation and reused the stock washers? My concerns are that they wont be able to properly distribute the torque load as the chamfer on the washer is not exactly the same and designed to work at 58ft. lbs rather than ~85ft. lbs that I will be running. Any information ASAP is great.

My advice....don't reuse anything. I mean, do u really even want to let even a smidgin 1% chance u might blow it again? I sure wouldn't, I would call whoever u ordered from and have them rush a one day delivery or something to u.

Nothing wrong with reusing them but the included washers from ARP were designed that way for a reason. I recommend against mix & matching. Just call ARP and have them mail you one. It should be free and only take a couple days in a plain envelope.
