Have a 91 Caravan SE AWD with 2.5L 4cyl. and AT Only 60,000miles. Most drive to work and short distances. Other day had to accelerate rapidly to avoid car. A few miles down road I note loss of oil pressure. I checked oil and it was diluted with gasoline. Changed the oil and in short order (less than 10 miles) it was diluted again and loss oil pressure. Think this van has electric fuel pump so I don't think it is a fuel pump diaphram problem. Engine starts up well and runs well but quickly losses oil pressure. Is the problem possibly associated with emission control circulation system. Perhaps fuel pressure regulator allowing fuel to feed back in the crankcase. Has me baffeled. Help! Thanks.
