How do you know boost is escaping?

honestly, it could be coming from anywhere IF it is a boost leak.

Car drives normally,car free revs normally,but when driving and boosting under load the boost goes to 5-9psi then bleeds out from somewhere its very loud.

If it's audible, it's most likely not something small like a vacuum line. Something like that won't really be audible from inside the car.

Especially since most of our cars have exhausts air filter mods etc etc.

I'd put my money on one of the gaskets (they're loud as). maybe turbo to manifold gasket, manifold gasket, front pipe gasket, dump gasket, either cat gasket etc. There are heaps of gaskets.

One of the cars I did had a gasket leak so loud that once you got onto boost, it started squeeling so crazily.

The workshop will know when they do your turbo. There are things to look out for e.g. if there's black soot above a certain part of the manifold gasket, it's an exhaust leak there.

The gaskets for pretty much all of the exhaust bits including turbo to manifold, front pipe (if you've still got stock 2 part one), cat etc will be checked and replaced if needed too.

should be right

      Ethanol Content Sensor - Always at 11%?

      By joshuaho96 · Posted

      The incentives are mostly the same, yes. Ethanol is cheap compared to the cost of doing 98-100 RON with crude oil alone. 87 to 93-94 AKI all with E10. In 2020 Canada mandated E10 as a part of their "renewable fuel standard" and is supposedly going to go to E15 in 2030. In California where there are only 8 refineries with two threatening to shut down next year it's been over 20 years now of E10 and 91 AKI maximum because there's just not enough refinery capacity or crude oil supply relative to the demand for premium unleaded fuel. And CARB's low carbon fuel standard means functionally none of the diesel available at the pump is made from crude oil anymore. It's almost all entirely 20% biodiesel blended with 80% renewable diesel (hydrotreated vegetable oil) now. The number of gasoline vehicles that support E15 or higher ethanol concentrations is surprisingly low, I can't imagine it being wise to play tricks like this without flex fuel sensors in most of the fleet.

      It's almost certainly the same as the one next to it.

      South Australia, which is hardly as far behind as the rest pf Oz makes out, and who is also not a paragon of progressiveness (read that as over-legislation) in the area of vehicle standards, has this to say on the subject: Adjustable coil-over suspension Aftermarket adjustable coil-over suspension components are suspension units that incorporate an external thread on the main body and corresponding threaded spring saddle that allows the vehicle's suspension height to be varied. If fitting aftermarket or coil-over suspension components you must submit an Application to modify a light motor vehicle form and a report from a light vehicle engineering signatory (LVES).

      Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers

      Those above shitboxes, mediocre and above usually have a turbo strapped to them, hence the slightly higher octane is required.
