I've got a 1978 B200 Dodge van. 318ci auto trans, 362,000mi. I've got about 200,000 miles on a good engine rebuild. Two years ago I replaced the timing chain, water pump and front end. I've used Castrol 20/50 and changed every 3k since the rebuild. It runs smoothly and DOES NOT smoke. I've tried going down a steep hill in low gear and then accelerating at the bottom of the hill and still couldn't get it to smoke. I don't see any oil on the ground under the van. It is "using"
1 quart every 400 miles. I switched to Castrol hi mileage 20/50 about 2600 miles ago and haven't noticed any change yet. Does anyone have any idea where the oil is going? TIA, -cadjak- posted
