Viper2k16 Posted April 26, 2016 Share Posted April 26, 2016 Hi everyone I have been having problems with my ford focus 2005 1.6 basically water has been getting to the engine at first we thought it was from the wiper jets but after closer inspection by mechanic water has been leaking from the coolant and flooding the spark plug chamber due to engine core plugs does anyone know this to happen to them and how much it costs to repair the damage thank you Quote Link to comment Share on other sites More sharing options...
Russ Posted April 26, 2016 Share Posted April 26, 2016 If it's the core plugs you could do it yourself and save £'s as the core plugs themselves won't cost much. Quote Link to comment Share on other sites More sharing options...

The root cause is the washer jets on the bonnet, very common problem as the rubber deteriorates some bathroom silicone around them under the bonnet will prevent any further water getting in there. The rear spoiler can also leak the to deterioration of seals around the bolts I've siliconed mine before it began 👍 1 Quote Link to comment Share on other sites More sharing options...
Viper2k16 Posted May 1, 2016 Author Share Posted May 1, 2016 ive got someone to check it out a mechanic and we cleaned out the engine with the hot air and he noticed afterwards water coming back out of the core plugs inside the engine Quote Link to comment Share on other sites More sharing options...
Russ Posted May 1, 2016 Share Posted May 1, 2016 You'd need to take the cam cover off to get to the core plug but it doesn't take long to get one out and replace it. A garage should do it easily and I would think well within an hour. (Have replied to your PM Viper2k16.) Quote Link to comment Share on other sites More sharing options...
enzo808 Posted June 19, 2016 Share Posted June 19, 2016 I have a Ford Focus MKII 2006 1.6 Petrol and my car was initially making popping noises and a groaning noise when accelerating and eventually my local mechanic found fluid in the Spark Plug holes. This noise has since disappeared (mechanic removed the fluid among other things) but I've now noticed the coolant level is dropping quite quickly so there is probably a leak somewhere even though mechanic raised my car on a ramp and didn't find anything. So I probably have the same issue as you, did replacing the core plugs resolve this issue? If so how much was the repair (parts + labour)? Any advice would be greatly appreciated as I'm worried it might be a costly fix! Quote Link to comment Share on other sites More sharing options...
madman Posted August 12, 2016 Share Posted August 12, 2016 i have 2 seized plugs that wont budge i tried and a garage has and my ht leads are white/beige over. when the garage tried to move the plug today and couldn't they first said core plugs leak water? whats a core plug and is this correct and could this cause fluid to leak in there to cause 2 rusty plugs, can it be easily fixed by yourself. i know from today my washer jets are leaking tho onto the plugs, Quote Link to comment Share on other sites More sharing options...
TomsFocus Posted August 12, 2016 Share Posted August 12, 2016 A core plug is simply a blank plug that fills a hole left by the original casting process. Yes they can leak, not sure how easy to replace on this engine. I had exactly the same issue on my Fiesta though, but it's now dry in there, so I don't know whether it was a core plug or if water got in from above somehow!! My plugs were rusted in but I did manage to break them free with a lot of patience! Quote Link to comment Share on other sites More sharing options...
