hello there
I have recently been suffering from a lack of power on me clio 182 and found out 2day when checking the leads & plugs that im getting oil all over 1 of the plugs... I was wondering if any1 as had this prob before or if any1 had any ideas wt may be the prob..

many thanks

sounds like piston rings maybe, but i would wait until the more experianced guys answer your question before you take my word for it

Thanks for the reply Eckascliovalver much appreciated.

From wt ive been told so far the prob cud be 1 of 3 things
1.Valve
2.Head gasket
3.Piston Rings

I cant see it bein the pistons rings else id be losein power all the time (i thinks) which im not as its a random thing, it can happen when i first startup (but dunt last) or it happens after the cars been runnin for so long which is how it dus it most the time.

Been on the blower to renault and they are askin £1400 + to replace the head gasket

Any advice on this matter wud be grateful.

sounds like a sticky valve?

does it burn oil?

Oil as in around between the lead and the plug or when you remove the plug allover the electrode end?

If its between the plug and the lead your cam carriers leaking (sealant gasket not a real one). Common fault but most people are lucky enough to just have the leak on the outside not near the leads.

Leakdown tests for the win, I had oil in one plug. (ring) Picked up a nearly new 182 engine for 250 quid and can break the old one for parts and make some of the money back hopefully

that'd be my diagnosis. On a mk1 i'd say rocker cover gasket. Since F4R doesent have a gasket, then it's the rocker cover sealant.

Not got much experience with the F4R yet

If the oil is near the left plug it could just be spilled when filling / topping up the oil.

Compression check and check the spark plugs when you take them out?

Lack of power could be all sorts of things.

The oil is in the compression chamber so when i take the plug out it is covered in oil(ELECTRODE END).

We dont seem to be burning oil, but i am losin a bit of oil.

If i am to do a compression test wat sort ratio should i be looking for.

Any help appreciated.
