I just inherited the family heirloom -- an 85 P-type with 112,500K. Almost everything is stock.
The engine burns oil through the tailpipe after excessive idling with city driving but, more of an immediate concern, is oil smoke from the engine after it warms up.
The smoke comes directly from the top of the engine, not from down below [please forgive my mechanical ignorance
] and continues for several minutes after the engine has stopped. The valve cover gaskets have been replaced a few times and I'm hoping this might provide a quick fix for this problem.
Another disturbing facet is significant engine pinging when on the highway under very moderate climbs. When attempting steep hills, of course, the problem becomes even worse. Premium gas is used but no luck there with alleviating the knock. I'm wondering if a Fuel Injection cleaner might rid excessive buildup within the combustion chamber that might be the cause. Then again, perhaps the problem is simply caused by a need for timing adjustment but this would be too easy! The plugs were changed 2 years ago.
Any advice here on the smoking and pinging would be most welcome.
And one last bugaboo. The engine usually starts on a dime but, depending on the weather (which I've narrowed down to the rain as the prime factor), there are multiple stalls before it catches.
Once again, thanks.
