Eurocarbits weekend sale inspired me to do a quick mini service on the car today, more fool me! changed the spark plugs and air filter, also flushed the coolant again to get rid of the last bits of oil after oil cooler leak. problem 1 - the sump plug will NOT loosen problem 2 - oily plugs, seems to be only on the ceramic, not the electrode end. (Was also on the thread but I'm presuming that's from unscrewing them through the puddle of oil in the holes, there's no smoke from the exhaust anyway) anyway, I'm off work tomorrow so I'm determined to attack it, has anybody changed a rocker cover on one of these, is it really as straight forward as peoples write ups suggest? Also, tips for the sump plug removal anyone? thanks p.s. The pic below shows the bad one and the depth of the oily puddle on the socket, the others weren't half as bad and the electrodes were dry and clean.
