Default Leaking Header!!!

i got a picco/omega XT .12 Rear exhaust engine on my car and it's leaking fuel out the header. Im using a novarossi .12 header. The gap around the rear exhaust of the motor is pretty big. Is this normal or do i need a different header ? Or bigger rubber spacer?

Picco exhaust outlet ports are smaller than most others. You need a Picco specific exhaust header and a Picco gasket (also different than most).

Default Leaks?

I use the same header on my MT .12 and sometimes I'll get a leak on the bottom. And it's caused by me brushing a wall on the pipe side (not that I ever do that! lol)You probley checked this but if the header isn't perfectly straight it wont seal. You can also use a dab of sensor safe Hi temp silicone. But just use a small amount.

I use A/C "O" rings for sealing, they last long than the regular gaskets made by any brand and won't leak any drop of nitro on my car,

The above from 'Big KAT' and my experience, is the ONLY acceptable solution with Picco's.

The Black O.S. Gaskets seem to last longer than any others.
Using a second spring on the Header to keep the Exhaust piping from moving around and this helps too.

To fix the leak we used the Team Orion headder & gasket.
for some reason Picco makes their exhaust outlet smaller than the Rossi's But then again, maybe they are hoping for header sales as well

Sorry D!! no pics on this one,, but yes there are Air Conditioning "O" rings,, they are green colored, and tell you guys any gasket from any brand can't beat the durability of an A/C "O" ring,, , these "O" rings comes in diferents measures, so , I recomend to take your engine to a Auto parts or an A/C parts for cars, and put the "O" ring that fit your exhaust but when you put the header it should enter thight,, belive me this should cure all your problems of leaking by the exahust,,!!!!

Ciao!!
