Hi , i have 2002 stype 8 cyl, i get strong oil smell with heater on, garage says oil leaking from valve cover , oil pan andiother areas..i had valve cover replaced , still leaks... garage now says crankcase has pressure,causing oil leaks, but eng running great, perfect gas milage,runs strong.. any ideas what could cause the pressure ????

 

Hi,

Can't be sure but ... this sounds like a plugged PCV valve. No ventalation = Higher pressure leads to pressure leaks.

Worth a look.
