Check for a blocked PCV valve it could cause a build up of crankcase pressure that caused the crank or cam seal to leak in the first place. Not sure if there is a flame trap or oil breather box like a Volve or some old Fords but any thing that results in the engine not being able to "breath" will cause excess blow by buid up causing oil leaks. Autozone have some popular workshop manuals for free on line once you register (for free) on their website http://bit.ly/autozone_repair_info. There is also a company that independent auto repair shops buy their information from that the same information inexpensively to do it yourselfers. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online -

This Year/Model has no PCV valve and I cleared a restriction in the vacuum line, gave still pegs right after running a minute or so -

I noticed my oil was almost a quart high, then I noticed the smell! Would this be piston rings of fuel pressure problem? 85,000 miles on odom.
