I recently started to hear a whoosh when hitting 2K. With no loss of performance I suspected a tear in the right angled hose leading to the turbo from the intercooler.
On my first inspection all looked OK. However, after looking closer I could see a concentrated amount of oil / general crap towards the rear of the turbo. I reached back and found a large tear / crack in the pipe just before the jubilee clip.
I'm going to replace it with a silicone version, but while I'm at it I though it wise to ask for any basic cleaing tips while the hose is off, or any general hints and tips?
I'm pretty hands on and can see what needs to be done. While I'm at it I may also clean and blank the EGR - any tips for cleaning? Full removal?
Thanks in advance.
The EGR system deposits carbon/ muck all over the insides of the inlet manifold, and inlet ports and valves (basically from the EGR valve all the way to the combustion chamber) the breather also deposits oily residue into the intake (usually before the turbine) - this sticks to and mixes with the carbon on the inlet manifold forming an oily goo - eventually choking the inlet and/ or bits of muck falling off and being ingested by the engine
My view is EGR cleaner is a quick fix at best - if it actually worked to remove all the carbon the engine would injest it all at once - with potential disasterous results - to clean the inlet manifold propery - you need to take the inlet manifold completely off the car and jet wash it or the like - once it has been properly cleaned the carbon should not build up again once a solid EGR blanking plate is in place
As far as i am aware no-one has fitted twin EGR plates or done an EGR pipe or total delete on a Focus TDCI 1.6 on the forum yet - ive done this with my 2.0L Mondeo (and other cars) and can confirm it improves the pick-up from low revs, throttle response and reduces turbo lag a little bit more than just a single solid EGR blanking plate
