This is an update to my post in "Through December 07, 2002" Tech Archives . You can read all the posts there. I thought this might be good info to report for 308 owners. The short version was that while driving I had oil spray all over the engine bay and then had a small fire. The problem was a blown o-ring at the oil filter housing. After further investigation, a problem was discovered with the Pressure Relief piston and spring. Seems it had been sticking and that explained why the o-ring at the oil filter housing blew out. The oil pressure piston stuck in a position where the oil pressure could not relieve itself other than finding a way to blow out, i.e the seal to the oil filter. When the car was being diagnosed and repaired the mechanic encountered a no oil pressure situation when the piston stuck in the full bypass position. The part was replaced and things seem fine now. Keeping my fingers crossed, of course.
