My '03 Tribute 3.0L, with only 55,000 miles, is leaking oil from a location just below the water pump, perhaps a crankshaft seal or timing cover. The belt and drive pulley get oil on them (not an oil spill). Is this problematic with the V6? Approximately what does a repair for this cost?

Try running some of that high-mileage engine oil next time you do an oil change (it helps to swell engine seals slightly). If the problem clears up or is reduced, then it's likely that the rear main oil seal is starting to leak a little. The rubber seals will harden up and shrink a little with age. I would also powerwash the entire area clean, so that way any leak will be easier to monitor and pinpoint.
Dear Sir, Here is the oil leaking Problem Identifying Technique
Engine oil leaks from the valve cover gasket are common.
The intake manifold plenum gasket may leak and cause increased oil consumption/burning and a spark knock during acceleration; the gasket should be replaced.
External oil leaks from valve cover gaskets, intake gaskets (front or rear), and the rear crankshaft (rear main) seal area are common. The rear main seal is an unlikely source. Normally, the bearing cap mating surfaces (as well as the sealing surface between the oil pan and bearing cap) are the source for the leaks.
If the oil filter casing shows signs of distortion from excessive oil pressure, theoil pump should be replaced.
Often misdiagnosed as a leaking oil filter gasket, the oil filter adapter can seep from between the adapter and engine block.
Carbon buildup on the top of the piston is common. As the buildup increases with mileage and over time, symptoms may vary from light ticking, to ticking/hammering, to hammering/knocking noises. Fuel injector cleaner often solves the problem.
oil leaks can come from many things.like front timing cover crankshaft seal, rear main oil seal,with engine running look under car around oil pan area check see if you see heavy oil leak which will come from loose or damage oil filter and seal or check oil pressure sending unit at bottom right rear engine block or right rear corner of the oil pump.if oil leak small leak the front crankshaft seal and rear main seal leaking .
SOUND LIKE FRONT CRANKSHAFT TIMING COVER SEAL OR REAR MAIN OIL SEAL LEAKING START ENGINE LET IT IDLE SEE IF YOU SEE OIL DRIPPING UNDERNEATH CAR LOOK FOR OIL LEAK AT TIMING COVER OR AT REAR OF ENGINE WHERE REAR MAIN SEAL LOCATED. CHECK ON TOP OF ENGINE INTAKE MANIFOLD AREA WHERE OIL PUMP DRIVE GEAR IS.O - RING AT THE OIL PUMP DRIVE GEAR WILL CAUSE LARGE OIL LEAK.OIL PUMP DRIVE GEAR IS LOCATED WHERE THE DISTRIBUTOR USE TO BE LOCATED.KEEP EYE ON OIL LEVEL IN CRANK CASE.KEEP PLENTY ENGINE OIL ON HAND UNTIL YOU FIX.I WOULD FIND LOCATE PROBLEM QUICK AS POSSIBLE BECAUSE OIL LEVEL GET TOO LOW ENGINE WILL SEIZE UP LACK OF OIL..
SMOKE UNDER HOOD COULD BE COOLANT LEAK FROM RADIATOR ITSELF OR CHECK FOR LEAKING TOP RADIATOR HOSE AND CHECK FOR LEAKING BOTTOM RADIATOR HOSE.LOOK UNDER THE HOOD IF COOLANT BOILING OUT COOLANT OVERFLOW JUG ENGINE OVERHEATING FROM BAD THERMOSTAT OR BAD WATER PUMP.CHECK FOR COOLANT LEAK AT WATER PUMP WEEP HOLE.IF SO WATER PUMP NEED REPLACING.ADD MORE COOLANT UNTIL LEVEL CORRECT.TRY LOCATE LEAK. IF CAR OVERHEATED AND BOILED IT OUT. SMOKE UNDER THE HOOD CAN ALSO BE CAUSED BY LEAKING VALVE COVERS WHICH CAN BE FIRE HAZARD IF OIL LEAKS ON HOT EXHAUST MANIFOLD.
Your info is confusing. The rear cam seal is not inside the timing belt cover, and the crank seal is at the bottom of the engine, while the cam seal is at the top.
Is there oil at the top, around the cam seal? Or just at the bottom? It's common for the oil pump seal to leak. If you get the oil pump reseal kit, it contains the oil pump seal and gasket, as well as the crankshaft seal. Make sure you seal the oil pump bolts, Volvo has special copper washers for this purpose.
Just try to locate the oil leak before replacing any more parts. Sometimes it can be something simple like the oil cap seal or the oil trap housing.
