It does obviously increase engine bay temps but does look better haha. The cat one, you should probably keep and just clearance it so it doesn't rattle.

Bawwxay Member 50 Member For: 1y 9m 14d Posted 22/09/23 08:23 AM Author Share Posted 22/09/23 08:23 AM So for now, heatshields will stay on. As for the sound…tightened up the exhaust manifold gasket and the gasket between the manifold and turbo housing (super difficult to get to bottom two bolts!) Seemed all alright this morning, after about a forty minute drive, decided to lay the boot in and listen. So no power loss at all, but as soon as the car comes into boost, anywhere between about 4psi+ under acceleration, doesn’t matter what gear I’m in, the ticking sound is present and more worrying than ever. Does sound like the exhaust manifold gasket “tap” but isn’t. any suggestions? Link to comment Share on other sites More sharing options...

You can usually see blackness from incomplete combustion on the gasket where it leaks if you loosen it off enough to see it. You also don't need a gasket between the manifold and the turbo, but that doesn't matter if you have one. 1 Link to comment Share on other sites More sharing options...

Pretty common for them to sustain damage when they get driven for ages whilst leaking. 1 Link to comment Share on other sites More sharing options...
Bawwxay Member 50 Member For: 1y 9m 14d Posted 22/09/23 08:51 AM Author Share Posted 22/09/23 08:51 AM Other than a few bits of rusty colouring on the outer edges of the gasket, it was near new shiny silver. I’ll have everyone know that this is a mk2 BA Xr6 silver top + turbo. 183,000kms. 13,000kms with turbo. even though the boost tee is set at 10 pounds, for a while it has been steadily making boost and then boosts hard (like sits you back in the seat hard) (a different feeling of boost!) but still reads 10 pounds max on the gauge in the cab. turbo is a Garrett GT3582R stock internals in engine. Also No Bov, crossover blocked with table leg floor stoppers lol Link to comment Share on other sites More sharing options...

It'll make 4psi on the brake with ease. 1 Link to comment Share on other sites More sharing options...
