My 2.7 engine smokes when started after it sits for a few days. If I drive the car daily it doesn't smoke when started.
I removed the spark plugs and noticed one plug coated in oil. Is the oil coming from worn out valve guides or the rocker seals? Rocker seals would be easy to install. __________________ This post was auto-generated based upon a question asked on our tech article page here: Pelican Technical Article: Fixing Common Oil Leaks - 911 (1965-89) - 930 Turbo (1975-89) |

The valve guide seals are letting oil run down the guide into the combustion chamber causing the engine to smoke, luckily only in that one cylinder. An experienced tech can fill the cylinder with compressed air (from an air compressor) and remove the valve spring keeper, collar and spring to get access to the valve guide seals and replace them. Because of the boxer engine design there is little danger of dropping a valve into the cylinder requiring the cylinder head be removed.

Can this also be done on a 3.2 engine or just the 2.7 engine?
