Fixed persistent thermostat housing leak.

Previous owner of mine had similar issues... this is what the intake looked like after repeated blow outs.

I went with a Billet specialties o-ring housing as well. The countersunk holes on mine were off a tad so I just used a longer bolt. After shot of the same intake, shame you can barely see it as it's a nice piece of kit.
Those pot metal chrome housings like to warp and leak..
