OpenFlash Header (OFH) Cracked--Worth Fixing? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Problem fixed. Had a defective one.

Thanks for your report

I think that welding it, and it not leaking afterward, would be iffy.

That whole area of the header looks "flaky".

How old is it .. ??

I think they should take it back, as being defective.

Definitely interested in age? Original owner?

Had the same thing happen to mine. Brought it to a local welder and 50 bucks later worked like a champ. Been running it for about 2k miles with no problems. Totally worth it.

I'll take it off your hands as is if the price is right.

If I was in a critiquing mood, it looks like... EDIT: I'm actually not going to open that can of worms or start that argument.

The header nuts to the block are M10 x 1.25, and if I remember correctly, so are the header-overpipe joint studs. Check the individual drawers with the little bags of 1 or 2 at the hardware store, or the miniature rack in the nearest Autozone. Anything labeled grade 8 with the correct thread pitch will work, in a pinch. That's what I use in a pinch if I don't have time to order proper hardware.

The part that looks "iffy" to me is not on the seam, but "fixing" the cracks radiating from the welded seam. Keeping in mind that the manifold is subjected to extreme heat changes and severe vibration.

Lol. Not trying to open any cans except beer cans. Thanks for the tip on the nuts. I found some extra ones that came with my TRD springs (I think) and they fit.
