Low oil pressure: Check the oil level. Check the oil pressure sending unit. If the sending unit is sending an accurate reading, either the oil pump is bad or the oil pickup is blocked.

The distributor should be held in place by a bolt that is near the shaft of the distributor. Is the bolt loose or missing? Does the distributor turn relative to the camshaft?
