I have some extra gaskets I could sell for $30 shipped.

This is directed at the op, or anyone that has tired alternative solutions, has anyone had luck fixing these studs/nuts so that they do not work themselves out?

I found myself in the same predicament this past weekend, and this was after a pre-track check where I put a wrench on each of these nuts. Might just need to add a spare gasket kit to the track day tool kit.

So I ordered some of the Vibra-tite mentioned earlier in this thread and have had two successful track days without issue since. That's hardly proof of anything yet, but hoping the stuff is doing it's job.

I have also used the Hot-lock with success, but no track days on mine.

This was the most frustrating part about the ace header when I ran one, and the odd leak like sound it makes.

are you talking about the sound it makes in the mid range that sounds liek flowing water in the middle of your dash?

Uh yeaahh thats about right. I was told its just the rushing sound of exhaust thru the piping (thin walled). Got rid of that noise and the leaky overpipe gasket with a switch to the Tomei UEL.

Heat cycle and re-torque everything, as heat/vibration will make things back out.

Alternatively, replace the stud/nut with a bolt if you prefer, and then safety wire the bolt.


Using the cycle/retorque method, I had no issues with my header, but i did need to retorque 2-3 times after install before it stopped turning after cycling.

i lost the install sheet, what are the torque specs again?

Been a few months since this thread last popped up, but wanted to share my solution.

Actually ordered the hotlock, but still wasn't convinced I would be worry free long term.

Ended up ordering 20mm fasteners from drilledheadbolts.com and safety wired them through. (my first time using lock wire w/plies, not the tidiest job)

Happy to note i haven't had any issues here since.

What metric bolts are you guys running instead of the crappy included hardware? (head size, thread pitch, length?)

im pretty sure it is an m8 nut but let me find the bolts. i know i tried a 30 and a 40 but i think the 40 was too long

PLX92 12-07-2020 10:25 AM
M8-1.25 X 20MM did it for me, that was with a 2-3mm split washer under the bolt head.
