Someone please help!

After driving yesterday i started to hear the fan running louder than usual. I've been doing some reading on here and people say if you could move the fan freely when off you need to replace the fan. But after getting my fingers in there i noticed i might be running into a bigger problem. Im new to this so i dont wanna get raped by a mechanic. Its a 99 Sport with 112k

It looks like your front crankshaft seal may be leaking.

The leak looks as though it is coming from the front timing cover/crankshaft seal. That will not be the cause of your fan noise but should be addressed as well.

Grab the fan blade, with the engine off of course, and give it a wiggle while watching the point where the shaft comes out of the fan clutch. If there is significant movement there the fan clutch will need to be replaced due to a bad bearing. Also if the fan does not free-wheel on the fan clutch the clutch will need to be replaced, that is more than likely the case and the cause of your noise. It would sound like the fan is mounted solid without a clutch, ie. a lot of fan/air movement noise.

At that point you would replace just the fan clutch not the entire fan. No need to replace the fan unless there is fan blade damage. I like to check between the bolt holes while replacing the fan clutch for small hair line cracks. If cracks are present then replace the fan blade otherwise use the OEM fan with a new clutch.

If addressing the oil leak while you have the harmonin balancer off examine it very closely in the area where the outer ring meets the inner ring as these were notorious for slipping off. If it is not lined up perfectly or the rubber that resides between the rings is rotted and cracked replace the harmonic balancer before it comes apart. It would be much better to replace while apart for repairs rather than on the side of the road when it decides to let loose.
