Clio 182
Hi guys,
Car started misfiring on me yesterday, never done it before, very down on power, not sure if was running on 2 or 3 cylinders but pretty rough anyway. Idle wasn't bad though, but a bit jumpy. Smell coming out the back was awful (bad eggs), I guess due to the cat being dowsed in fuel, and looked a bit more steamy out the back.
Had the AA out, he checked sparks on coil pack, all very strong. Had a look down plug wells, they were dry, but he sprayed them with WD40 anyway, didn't make any difference. He suggested plugs, then leads, then coil pack. He's known coil packs spark well, but be out on timing.
This happened on Thursday night, but I had cleaned the engine bay over weekend with a fair bit of water, so was worried it might be that. Had the ECU out this morning and left it somewhere warm all day in case it was wet.
Had Denso plugs in, so I changed them for the NGK's today, hoping that might be it. But had a nasty surprise and not sure how serious it is. Plug 1 was dowsed in fuel, Plug 2 had quite a bit of oil on it, Plug 3 had quite a bit of mayonnaise (looked very like water/oil mixture) on it, and Plug 4 also dowsed on fuel.
Now worried it might be early signs of head gasket! It's a 182, 70k miles which would be a bit surprising. It is using oil, probably about a litre in 2000 miles and can't find a leak. But no mayonnaise in filler cap or dipstick and no oil in water. Anyone else had this?
Got some new HT leads arriving tomorrow, so when doing them will do a compression test too to find out more and see what happens, but any thoughts welcome!
Bloody french cars!
