If it's not burning the oil, it's still leaving the crankcase somehow, right? A little CSI here. Where might it go? If it is leaking from the crankcase, might it leak somewhere not immediately obvious? I once had an old Range Rover that leaked from the transfer gearbox into the main gearbox - net result = overfilled main box and zilch in the transfer case and lo and behold the transfer case imploded after it got rather hot in there. The point is, no oil on the driveway, so no suspicions. Same vehicle also pumped out engine through the rear main bearing seal into the bellhousing. It emptied slowly but surely through the bellhousing drain hole, but only usually on heavy breaking on a run. Only spits and spots on the drive. The engine needed much more oil than seemed to be pouring out of it. Classic signs of leakage while driving: a shitty mess on the rear that don;t mix with water too well ;-) HTH and good luck. -- Cheers, Cotty ___/\__ || (O) | People, Places, Pastiche ||=====| http://www.cottysnaps.com _____________________________ -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
