Have you modified the original intake?

Nail polish remover is acetone, but you have to be careful with rubber and plastics, some of them are damaged by it. It is much more aggressive than alcohol

To remove adhesive residue you can use alcohol.

At the garage, they offered to install a turbocharger that was just as reliable as the original and more economical, and that's what they installed. The car isn't leaking oil or coolant, although the throttle body is wet but not dripping; it's oil from the valve cover breather, which it seems...

My 156 hp engine has 156,000 km and the rocker cover has never been removed. At approximately 115,000 km, I replaced the timing chain tensione. It was a simple matter of removing the old one and installing the new one without disassembling anything else. Since 125,000 km, I've been using 5W40...

Here in Spain it's very rare to see an RCZ, in the four and a half years I've had mine, I think I've seen at most four others.

If, after idling for a while, you rev the engine and smoke comes out, it means the valve stem seals are bad or there are leaks from the piston rings. Water vapor coming out when starting from cold is normal; it's condensation in the exhaust pipe. You can also remove the spark plugs and inspect...

If the engine isn't overheating, the pump is obviously working. The turbo's electric pump is located below the turbocharger, and if it's quiet, you should hear it running when you turn off the hot engine.

The pump works in a curious way, there is a wheel that, when the engine has warmed up, an actuator makes it touch the accessory belt, and through friction, it moves the pump. The timing chain is a chain, not a belt.

Is there foam under the oil filler cap? do you see black sludge? Maybe the oil is contaminated with coolant and the VANOS fails because of the dirty oil. If it has had several overheatings, the cylinder head gasket must be suspected.

It also has a hose that goes to the intake and you can do the test I mentioned.

There's a simple way to check if the PCV valve is working properly. With the engine off and cold. Disconnect the hose connected to the rocker cover that goes to the turbocharger intake and replace it with any hose that fits snugly. If the PCV valve is working correctly, with the mouth, when...

It's located below the OBD2 connector

The difference between 235/40 and 225/45 tires will be minimal in terms of comfort. As I said before, this has been discussed extensively on this forum, and the conclusion is that a sports car will never be soft and comfortable; you have to accept it for what it is: a sports car. Furthermore...

Position memory also include the exterior mirrors. In cars with position memory, the mirror motor is different, with position sensors and many more wires than those without. The first drawback to adding non-installed extras is usually the wiring.

The standard tire size for an RCZ with 19" rims is 235/40/19, not 35. The issue of suspension and tire comfort has been discussed extensively on this forum, with the conclusion that there's no clear solution. Personally, I've been driving cars with stiff suspensions for decades, and I don't...

For viewing and clearing default codes, checking fuel rail pressure, intake pressure, throttle position, and more, it works perfectly.

Cheaper and works great, I have it https://www.amazon.co.uk/Pennle-Bluetooth-Scanner-Automotive-Diagnostic/dp/B0DJ6Z3646/

Welcome In terms of mechanics, the RCZ is similar to other Peugeot and Citroen models, mainly there's no need for someone who specializes in RCZs.

The carbon buildup in the intake ducts would need to be cleaned.
