The first thing that happens with lack of oil is the tappets start rattling (being hydraulic). There are plenty of weird sounds. Sounds of an engine running with no oil. For a short time this won't seize the engine. When it happened last time I drove it for 4 miles with no oil pressure, convinced I had blown the engine, but after replacing the oil pump rotor and priming with vaseline (does the 2.3 need priming?) it started fine and ran quietly after a few minutes. The car then ran for a few months before losing pressure again with the same symptoms. The filter and oil have always been changed at 3k mile intervals. -- Regards, Danny http://www.gaggia-espresso.com (a purely hobby site) http://www.dannyscoffee.com (UK advert for my mobile espresso service) http://www.malabargold.co.uk (UK/European online ordering for Malabar Gold blend) swap Z for above characters in email address to reply
