4.7 oil leak @ crankshaft pulley?
i noticed today alot of oil build up on the front of my oil pan just below the crank shaft pulley. I saw my oil light come on a few times when i started the motor which made me look into it. I checked the oil and it looked lower then normal so i got to inspecting further and seen all the oil. It was spread from the oil sending unit all the way to the other side of the front of the pan. Im really praying its not the seal on the crank shaft. Has any one ever had this problem? And if so does the oil pan come out without lifting the motor? Any help is appreciated. This truck is my daily driver and my sole means of transportation to support 3 daughters and i cant afford to seize the motor or some thing. Not to mention this truck is my baby..

`What you have is mainbearing seal failure ,a normal maintance item at about 100k mi.Do have it repaired ASAP,and the rear main as well,best to do them in pairs and save the labor cost.This is a labor intensive job if you do it yourself.Best suggestion have a shop do it with a warrenty in the deal.Shop around for quotes...........

Just make sure the oil level is always good no low, to the max position, check it every morning and refill as need it.
Don't do long trips at a high speed and fix it ASAP

If it's not leaking too badly, you don't need to do it right away, but do it as soon as you can - keep an eye on the oil level and put a sheet under to keep the oil off the driveway.
If your rear crank seal isn't leaking, I wouldn't touch it - this requires a lot of different disassembly and in my opinion, you won't save time or money doing both at the same time.

Before you get started on this, do clean the engine to confirm it's that seal, then, get ALL the parts & tools that you'll need, and finally, get a copy of the procedures you plan to use & visually plan it all out. When you change the seal, use the proper removal/installation tool & be careful not to scratch the surface of the crank where the seal rubs, and before installing the new seal, inspect that area of the crank to see if it's completely smooth - sometimes the seals fail because their quality is crappy, sometimes they leak because there's a groove worn into that area of the crank allowing the oil to creep by. If you find that the crank surface for the seal is either worn or defective, you can repair this without removing the crank. You can use what's called a micro-sleeve and an oversized seal. The micro-sleeve is a very thin and hard sleeve that slides over the crank seal area and is bonded to the crank. The oversize seal then goes over this sleeve & holds in the oil.
