Presuming you are talking about an oil leak from behind a pulley? All shafts as they exit the engine, have an oil seal fitted in the case and supply a tight seal to the shaft, if oil is leaking the seal is worn and needs replacing. depending on what the pulley is driving (cam belt), it could be a big job.

Find tension pulley release


Undo the nut holding on the pulley until it is loose . Behind the bracket holding the pulley shaft you will find a long threaded bolt that moves the shaft up or down a slot . When finished the job make sure the pulley nut is re-tensioned.

Broke the harmonic balancer bolt on my 1994 Dodge Intrepid, can the car drive with the bolt broken off about 1/2" deep? It seems snug.


the harmonic balancer is slightly pressed onto the crank shaft. It does require the bolt to hold it into its correct position. If you drive it with the bolt broken the pulley will eventually work its way loose from the crank shaft. This will cause damage to the crankshaft and will cause the accessory belts to come off as well.

I have a Chevy Avalahnche and I am on vacation in South Florida. Yesterday when I went to turn Right, I had all I could do to turn, it was like the power steering went out. Once I started moving it...


Hi, the power steering pump, on the driver side of the engine, is driven by the serpentine belt. The pulley for power steering, is fairly large, the pulley is pressed on the power steering shaft with a special tool. It is also removed from this shaft with a similar tool. The shaft that holds the pulley, has a tendancy to fracture, resulting in what looks like no problem, but in fact, the pulley is turning, and nothing is happening. The best way to see if the shaft is broken, is ( with the engine off ), try prying out on the pulley, with a large screwdriver, or a prybar. If the pulley comes out of the pump, and actually slides toward the radiator, the shaft is broken, and you will need a new pump. Good luck...Coop

Leaking oil left side of motor


Since it's not clear whether you mean driver side or passenger side, I will address both.

On the driver side, the most common leak is from the distributor. This can be caused by the distributor shaft exterior o-ring, or it can be caused by the distributor shaft interior bearing seal. To determine which it is, remove the distributor. First detach the spark plug wires, then undo the bolt that holds the distributor to the head, then pull the distributor out of the head. You will see the o-ring on the exterior of the distributor shaft. This is a $0.50 part, so just replace it with a new one as long as you have the distributor out. The bearing seal is on the inside of the distributor. To inspect it, undo the three bolts holding the cap to the distributor body. Pop the rotor off the shaft, the unclip the inside plastic cover. If you see any oil inside the distributor or the distributor cap, this means the seal is leaking and must be replaced. You can get a seal and bearing replacement kit from kbox.ca. Or, you can just buy a new distributor. Note: To get the distributor back in place you must align the shaft correctly with the notch in the camshaft. There is a right way and a wrong way. If the shaft seems to be aligned but does not go in, pull it out and rotate it 180 degrees, then put it back in.

The other possibility on the driver side of the engine is the main seal between the engine and transmission. If this is the case, you would have to either drop the transmission or pull the engine to replace it.

What if the oil is leaking on the passenger side? If it's coming from behind the timing belt cover, there is a camshaft seal and a crankshaft seal, both of which can leak oil. To get to them, you will have to remove all accessory belts and the alternator, remove the exterior crankshaft pulley, remove the engine mount (support the engine) and the timing belt covers, remove the timing belt, then the crankshaft pulley and/or camshaft pulley, whichever is necessary to replace the leaking seal(s).

Where else could oil be leaking from? If it's coming out from near the top of the engine, that's the valve cover gasket. Remove the valve cover and replace the gasket. While you're at it, replace the spark plug tube seals.

If it's coming out from near the bottom of the engine, it could be the oil pan gasket. Remove the oil pan and replace the gasket.

One more possibility for oil leakage: The head gasket. But in this case you would have noticed other symptoms besides just an oil leak.

Good luck! Let us know how it turns out.

A Pulley and a Power Steering Pump is needed -99 Ford Crown


well let me explain if? the pulley was spiining on thr shaft to begin with on the pump..putting a new pulley on a worn shaft won;t work!! there is 2 ways to fix this!! one is if this is the case then you can use JB weld around the shaft and i mean use it and even put some inside the pulley then put the pulley back on the shaft let set for 4-6 hours before running the engine also you can go to a manchine shop or a parts store and ask for a roll of brass shim stock about .03-.05 thousand's and rapped a few times around the shaft to create a tight fit when you press the pulley back on making sure you leave about a 1/4 inch extended past the end of the shaft so it will go in the pulley on install

I have a coolant leak coming from the front of the engine. looks like it is leaking around the cam shaft pulley. The vehicle is a 2001 Nissan Frontier v6


Sounds like either the water pump or the thermostat housing. The water pump has a small hole in the bottom where the shaft comes through, when the water pump gets worn it will leak here so you know to replace the pump. The thermostat housing will be at the motor end of the upper radiator hose where it attaches to the motor. Hope this helps.
