    Wink Turbo direct injection NISSAN engines. 1.6 litre

    Regarding the latest generation Pulsar SSS – the 1.6-liter turbo direct injection donk.

    It’s the direct injection bit. It will cause carbon build-up on the inlet valves.

    I know these engines, and they are improving them.

    My partner has a Pug 207 GTI and I gave her intake valves a DIY clean at 75,000 clicks. Six hours! $1,000 at the dealership.
    Started getting fault codes after six years. The Peugeot dealer pumped two cans of SA459 through it and left it overnight. But after a few months the fault came back, so I bloody-well cleaned the intake vales myself with SA459 directly sprayed into the intake ports, with valves closed. Let each port soak for 15 minutes X 4 times and with picks and brushes cleaned the crap carbon out. You will need an air-compressor to eject all the carbon crap back into a rag.

    Since then at every oil change I pump a can of SA459 through it and then change the oil. May raise a fault code, but a cheap diagnostic tool will reset it. Got mine from China for $19.99

    Absolutely recommended for DI turbo engines. Remember the same donk is in the Renault hotties as well.

    Product: Upper Cylinder Cleaner

    yep, been an issue for just about all direct injection engines.

    The M35 Stagea guys have some good info and tips on SAU for getting the gunk off. its not a fun job.
