    Default 1.6 HDI Injector issue

    I was reading a C4 forum and came across a post about the fixing bolts on the injectors becoming loose over time and possible engine damage occurring Just checked mine and 3 of the injectors had loose fixing bolts only a little more than finger tight. As this can lead to very expensive failures I thought it worth a mention it may have come up before on this site ,but as Im a newbie I couldn't find anything. Defiantly worth checking PS engine running smoother since they were tightened .

    Yes, this leads to a leakage of fuel past injector (esp on apparently No 1 & 4 Cylinders, UK C4 site) ,we could see and smell fuel , which then leads to injector becoming frozen in the head (Carbonisation around injector ?) Fix is 2 cheap seals if you can extract the injector. If injector is destroyed in this process ie removal they cost about $800 +. Known problem with some Fords and BMW/Mini that share similar engine and also many others according to my diesel mechanic ,fortunately he was able to eventually remove the injector without damage !!

    signs can be chuffin sound and a hard black tar substance leaking out of the injector hole. I had this on my Picasso, I got the motor very hot and whlie the tar was soft, I managed to pull the injectors out. the copper washers were destroyed and had to be replaced... after the seat was recut.. job was a good one
