Whenever I do a cold start, the oil pressure light is always the last light on the cluster to go away. Usually it stays lit for about 3 seconds. Other than that it has no issues. It has 10w30 oil in it and the temperatures have been about 20-35 degrees fahrenheit, so not the ideal oil viscosity. Any thoughts? Also one time it was about 14 degrees out and I started it, and it made a terrifying sound. Then it sounded like the engine fan was running furiously, almost like when a school bus engine fan runs. It also has a slight squealing under the hood when cold. Once its fully warmed up it goes away. I think I’m going to have the timing belt, tensioner, and water pump replaced soon. Also there’s some oil leakage on the passenger side near the oil pan and under the timing belt area. Could this be a leaking camshaft or crankshaft seal? Any comments or advice would be appreciated.

Oil is full. I keep it topped of. I’ll try that motor flush. I only have 1000 miles on the oil that’s in it (mobil one high mileage synthetic) but it wouldn’t hurt to change it I guess. 5w30 is probably preferred in this climate because it never really gets over 75.

Had cam seals replaced by a reputable mechanic (Independent Auto, Anchorage AK) and problem disapeared. Oil light gors out right away and slow oil leak has stopped.

Temperature might be making a difference, but something is definitely helping. I’m getting an oil pan heater installed so I don’t have as much of an issue when it starts getting below 20 because it hates being started and driven in that weather. I still might try the motor flush but I want to have the freshest oil possible come september, so I’m putting off the next oil change until then.
