I just signed up today to the forum, but this post came in very useful at the weekend. My DCI was running poorly for a few weeks, with signs of unburnt
fuel on the back bumper.
I followed the guide and got the
out eventually and gave it a good clean, although the car is running much better, I noticed that I still get a strange noise under hard accelleration..... The noise sounds like air escaping under pressure, however on quick inspection the
pipes etc look ok.
I did notice that the plastic shutoff valve bolted to the inlet manifold was missing
a gasket, I assumed it should have had an o-ring seal, so will need to get one.
The question is, is the pipe connecting to this part coming from the intercooler ? and if so how much pressure is going through this joint, as the noice I get sounds like air escaping through a small gap.
I've also discovered that I should be able to get my finger through the ports in the inlet manifold, so I'll need to remove the
again get them properly cleaned as carb cleaner runs through the outer one, but not a significant amount, so the flow is likely to be restricated.
Are there any tips for cleaning the deposits from these ports without bits dropping where they shouldn't ?
