I know that some oil filters have a check valve (a rubber flap) that prevents the filter from draining back into the sump when the engine is shut off. These filters should be used, especially if the filters are in a horizontal position as on the V4s. If these filters are not used, the engine will be cranking without oil supply/pressure to the crank- and camshaft bearings during the first seconds, as the oil filter has to be filled up first. This will lead to more engine wear. How long does it now take for the oil pressure light to go off? (Even better: fit an oil pressure gauge.) It should make no difference to the time it takes to fire though. -- MH '72 97 '77 96 '78 95 '79 96 '87 900T8 http://go.to/saab96
