    Ok, here is the deal. I found that all my pulleys and fan blades were coated with oil. I initially thought it was my fron crank seal that goes in the timing cover. I found that when I took off my bottom serpintine pulley that bolts to my harmonic balancer, that some oil came out of the whole once I remove the center bolt holding the pully on. Is this normal? This appears that this is where my oil leak is coming from, and the bottom pully is slinging oil all over the place. What would be causing this leak? Any help would be great.................Thanks.

    Maybe some kind of oil leak within the crank?? I'm not even sure if that's possible... If that's what it is though, start planning what you want on your newly-rebuilt (or new) engine!

    before you assume the absolute worst, are you sure its motor oil??? if it is, do you have an oil cooler in front of the radiator that could have a whole and is sucking the oil through?? check the radiator fins for oil....do you have an a/c condenser on your truck? they use oil for the compressor and maybe it has a hole that is allowing the fan to pull the oil through to your engine....same thing for your tranny cooler (idf you have one) and power steering fluid cooler which is located on the crossmember under the radiator.....you may not have any of these options, but if you do, make sure you check them out...just a note, my oil cooler had a hole and i had oil all over the place before i got it fixed,.....good luck
