My 12 valve is leaking oil from somewhere on the front of the motor. There just ins't enouph room to see specifically where its coming from. It only leaks a very slight bit, hardly noticable on the dipstick, and only a few drops on the driveway when its parked. I used degreaser to clean it all up in hopes of narrowing it down. The problem is that when i drive it gets spread by the wind and serp. belt.
Can anyone suggest common leak spots on the front of the engine. It is not the Valve covers and it is not the oil pan or filter. It seems to be coming from behind the fan pulley, but it is hard to tell.
Thanks

 

sprinkle flour all over the front then take it for a drive for a half hour..............you will see the oil leak source then ..........................

 

That will make a mess, But sounds like it'll work. I'll try it tomorrow. Any thoughts on what would be back there that would leak.

 

front seal or maybe the seal on the vac pump........hard to say

another good thing to do would be to pull yer fan off so the wind dont blow the oil all around.............I think its 17 mm left handed thread

just dont run yer ac with the rig stopped......temps will be fine

 

does this sound like it could be a cracked timing cover case caused by the KDP. I was looking on the internet and got alittle concerned, because this seems to be where the oil is originating

 

if it was the KDP it would be a **** load of oil not just a drop or two

 

That should be a relatively simple fix. All you need to do is get a timing cover gasket and a crank seal. Most of the bolts you will be dealing with are 10mm. 2 1/2 hours star to finish is all it took me to change the seal and gasket on two trucks. Just remember the fan has LEFT hand threads. Also leave the belt on to assist you with getting things loose.

I have seen them with only a slight crack ....... but if I had to guess its the case seal....

 

Yeah, most times it's the front crank seal, had to speedy sleeve mine this sunner.
