Sorry Im new but Ive found lovely oil coating my spark plug electrode (#4 only), threads, and its dripping into the combustion chamber, even a little on the boot. I want to have the valve cover gasket set changed, does this sound okay?<p>and no my engine light isnt on and smoke is not coming out my exhaust, but I do not have a steady idle and my gas mileage is below average.<p><br><i>Modified by Kenzo at 10:52 AM 8-23-2009</i><BR><BR>

Re: Oil on spark plug electrode, threads, and boot 00 s70 GLT (Kenzo)

Well, it's very easy to have oil coating the rubber boot, threads, even filling up the well where the plug sits, literally bathed in oil, if the oil cap gasket is bad or if over a number of years oil has been spilled during top up. <p>Perhaps you just need to replace that plug and see what happens but it doesn't sound like you need to replace the valve cover gasket. Maybe there's something wrong with that particular coil also.<br>

Re: (Kenzo)

Are you positive it is oil and not just unburned fuel? I would replace the plug and see what happens. If it really is oil then it is going to be either valves or rings, more likely the former. You may want to do a compression test on that cylinder.

An actual gasket is not used, Volvo uses a special gasket compound that you apply with a fine knapped paint roller. This needs to be evenly applied to the cam cover interface surface. <p>This material only cures with the absence of air. So once applied and the two halves are re-mated, then the compound will cure. The most critical part of the job is maintaining your camshaft timing. I’d also recommend replacing all four cam seals in the process. Hope this helps.
