I was doing a little maintenance on the truck today and noticed this fresh oil towards the back of the engine.



Is this normal for a truck with 140000 miles or should I be worried? My oil level seems to be fine.:confused013:

Its just your rocker box riser gasket doing a bit of weeping. You can try and tighten the bolts (I think the torque it 18ft #'s) to see if they are loose, if not then just go get a new gasket and put it on, no big deal. I wouldnt want that leaking, its going to make its way all over the back of the motor and trans. It will end up being a mess.

No, very little idle time. I have noticed a loud ticking that sounds like its coming from the passenger side when im stopped at a red light if it means anything.:confused013:

Do you do alot of idle time?

do the valve adjustments, engine due, and at the same time change the VC gasket. i like lots of Permatex High Tack brush on, keeps the gasket sealed to block and VC. takes the heat

acetone works well to cut that baked coked oil on the VC and head with a wire brush
keep it away from wiring connectors and plastic, dissolves it.

wear chemical gloves and eye protectors

When you idle diesels they tend to start slobering. That's when oil starts coming out of seals like the valve cover. It's best not to let your truck idle for more then 10min. Any more you can wash a cylinder and you're "wasting" fuel.If idle can't be avoided then have the pto high idle enabled so the fuel and charging system don't get taxed as much.

got it. i do already have the idle enabled on my truck. its a 03 so it does it automaticly after a few minutes. (kicks up to 1000) so i should prevent cylinder washing from that. its just so cold here right now and i just hate driving away with a cold engine
