If there are any here...

Anyway, direct petrol injection engines. I have one. So like a diesel the fuel is injected direct into the combustion chamber. Since the engine ventilation pipe connects to the inlet tract, so engines fumes are burnt, you get quite a lot of oily gack sucked into the engine. With a normal injection system, this is washed by fuel and doesn't build up on the backs of the valves, with a direct injection system....

Well, a pic says a thousand words: http://www.alfamanservices.co.uk/news1.php[^]


So given the car was running like crap, I pulled the inlet system off, and lo and behold, big gunk build ups. I got some CRC valve cleaner from the US, and with a good scrape around cleaned each valve in turn (making sure they were close, so the crap didn't get into the cylinder).

And the result is different engine completely. Now it has throttle response, is willing to rev, and has crisper feel all over.


So if you have a GDI engine, and its done more than 30k miles, you might need to get it cleaned.
