Oil spots on tailgate

[retirednak]

I went to get something out of my bed today over at my buddies house that is having idle down issues with his rig. See 911 help section Anyway,I noticed I have fresh oil droplets on my tailgate. My first thought was my transmission is finally given up and is leaking fluid since I hurt it even more towing him and his rig back. After crawling around I've not located any leaks other then a wet vent pipe. I thought I noticed burning oil smell at slow speeds or when accelerating back up to speed while towing.



With a tad over 100K miles,am I right thinking the filter inside the valve cover needs replacing and is causing some blow by? Or can it be cleaned. I can't think of another reason for oil drops on the tailgate.



Am I overlooking anything?(besides my buddy owing me fresh Moose meat for the tow)

Check your oil level. If it is overfull then you could have a bad injector that is leaking. It will do internal damage if not addressed right away (injector).

The oil level is fine,its not making oil. I'm do for a change,my analysis will let me know if I'm getting anything unusual. Wouldn't a bad injector show other signs as being bad? Truck runs great,starts great and idles smooth. No white or black smoke. I thought I read some where that if the engine was producing extra blow by, to clean or replace the filter in the valve cover?

You might check the rear end maybe a pinion seal.

The device in the valve cover is nothing more than a separator that returns liquid oil to the crankcase, similar to what Mercedes used 30 years ago. I would check to see if that Volant intake has left you with a dusted engine.

It's been discussed on here fairly recently, take it apart and clean it.

I did notice I have a moist pinion seal,doesn't look like its enough to sling around. I'l keep looking.

 

[rscurtis]

If you were leaking gear oil, you would clearly smell it.

Sure you don't have a leaking front crank seal. Same thing on mine and its a leak on the front. I hate changing crank seals.

 

[retirednak]

I believe you hit the nail on the head. Damn,looks like a crappy job.

Look at the bright side- it's better than my diagnosis.
