My 407 2.0 HDi is at 185,000km. Havign had it a couple months and put over 1000km on it, I am about to do an oil change and am wondering if it is worth running a can of upper engine cleaner through to clean up the inlet side.
Obviously, I would do this prior to the oil change so I can clean any remains out along with the used oil. Our Subaru gets this done every 10,000km as a matter of course.
As I have no idea if it has ever been cleaned before, there is a high likelihood it is pretty filthy in there and I don't want to release a ton of deposits into the engine and on to the DPF.
Is it safe to do?
Would it likely make a difference?
I guess the alternative is to take off and manually clean the EGR and inlet manifold - presumably time consuming and requiring new gaskets.
Any advice from those with more experience would be appreciated.
