I was examining my engine yesterday to see if I missed any mud, and as I was looking, i seen what looked like oil leaking at bottom of engine right below crankshaft pulley.



the sway bar is in the way, but this is right above front suspension and right below crank on front of motor.

I know for sure its not the oil pan, it is clearly leaking from behind the crank pulley. It wasnt there 2,800 miles ago when I changed oil. Im not sure if the mud puddle I went through at the beach cause this. After discussing this with STL, sand may have gotten in there and tore the seal, but we are not sure. What we are sure about is that it is for sure leaking and i for sure is going to get fixed!

So now this leads to me asking...How in the hell do you replace the seal? I have a Haynes Manual, I'm not sure if it tells how. I know I am going to have to remove the cooling fan and schroud to make room. even so, its going to be a ***** to get to. from the bottom, the trans cooler hard lines are an obstacle.

So what do i do, just pull off the drive belt, remove above items, then remove pullet and harmonical balancer? how do i get to the seal and how does it come out? someone please help!!!

thats what i figured, how hard/easy it it to replace. I know its a pain to get to, but other than that....difficulty level? How-To?

surely to goodness that not it. That is rear seal. That s disassembling the whole effing motor. I dont thing that is right (at least im hoping). I hope its just pull pulley and balancer and all pop our front seal and replace like Redrocket has told me.

It is super easy

If you can get your hands on the removal tool a ten year old could do it. If you cant get that tool u need to remove the front cover which is easy but time consuming.

for the pulley. you should be able to pull the seal out with a screw driver or scribe bc you don't care what condition the one coming out is in but just make sure all the surfaces are clean before you put the new one on.

l tool for the seal.

if u use a screw driver be careful not to gouge the surface the seal goes in

I know on my 94' Ranger, to get the crankshaft pulley off, you had to use like a 22mm socket on a big nut. On the 4.0 how is it? How do i get that pulley off?

They can be a bear. Remove whatever is going to get in the way for sure. Only way I know of is to use a harmonic balancer puller. But other things say you need long bolts, not sure what that means. But if you use a puller to remove it, but sure to push against the crank bolt and not the crankshaft or balancer itself.

I'm a little effing mad right now. Maybe I should have checked after Morris said something. I got truck all back together with new seal and all. Crank up the truck and I hear sqeaking. I HATE sqeaking. I look over top of motor, underneath, etc...

Mom's bf looks at it with me and he says it sounds like a bearing. We climb underneath and as we're looking/listening, a drop of something hits him in the face. We look a little closer and it is goldis colored liquid dipping from above harmonic balancer from--------THE WATERPUMP!!! So that's what the sqeaking is. I guess the bearings are going out. I have also noticed I can't keep coolant in the resivoir, I always have to refill! And Dustin (ranger_1999) noticed my resevior the other day.

So now I'm going to buy a waterpump tomorrow and install, oh joy more mechanic work. I'm becoming the regular mechanic lately. I bet I replaced that seal when it didn't need it, oh well, It has a new one now. Waterpump "shouldn't" be too bad.

I never did post my pics from the oil leak. Here are the pics, as you can see, there was ALOT of sand on the harmonic balancer as well as cakes on the front seal. it was nasty, i cleaned this whole area up with brake cleaner.













Also here is where I broke the waterpump bolt:



Sara's Dad got that out no problem though!
