engine using oil- no leaks?

[doodad]

Anyone have any ideas of where the oil could be going? I have 129000 kms on the truck and warranty time is running out. In 4000 kms i had to add a litre twice. The truck is not running hot,good power good oil pressure. , and isnt blowing smoke, still stock. I am wondering if this has something to do with the intermittent engine noise. Had it to the dealer for the second time about the noise they cant figure it out. I left in disgust and drove 300 kliks to the closest Cummins shop. The tech support manager came out and found a blown exaust seal in under a minute. We used his temp gun to verify. He told me to get rid of the mopar oil filter ASAP. Gonna get it fixed under warranty this week. He also showed me some warranty horror stories regarding DC where there was documented" cant find the problem" multiple times , and then 2000kms over warranty valve stem broke and cracked block. DC says too bad warranty is over , i dont want this happening to me. He says demand for it to be fixed before warranty is over, make the noise go away, haha sure easier said than done but that is my next mission. I bought this truck for the engine mostly although i love the styling of the truck i have had to replace a lot of things in 11 months such as,



muffler (defective baffle, vibration drove me crazy)



track bar (replaced with moog , zerk fitting)



oil pressure sensor



rear axel seal (drivers side)



backup light switch



DRL light switch



Front crank seal



valve cover seal



belt



front pads (twice, different brands still pulls to the right and squeaks in traffic)



exaust seals (being done this week)



steering box adjustment (TSB being done this week)



Fuel sending unit(definetley on its way out goes on the blink every few days)



Whats next is there anything else i can expect. With all this said and done,(dont mean to ramble on) i love my truck. i just hope i dont have to keep repeating the same repairs.

I would bet your turbo is worn out and is letting the oil past there. I have heard life expectancy of these turbos is about 125-150k miles. If you don't let the turbo cool off the life is less. I got 175K out of mine with decent care but after getting gauges I realized I was not as good to turbo as I thought I was. shut off temps were still 450 rahter than 300 as they should be.

I pulled off the intake and checked the turbo. It was snug as a bug no play lateral or vertical. , does this mean its okay? The silencer ring is still in do you need to take it out to properly check turbo?

If your turbo is leaking you can remove the outlet hose to the intercooler and see if it is oily. The only other place for oil to come out if there are no leaks will be in the exhaust. Is your truck smoking? This could also be coming from the turbo. It is normal and good for your engine to use 1/2- 1 litre between 5k mile changes. If your dipstick level remains in the safe zone in-between changes you are doing fine.

Thanxs, im gonna check the outlet hose tommorow in the light. The truck doesnt smoke YET, still stock . If i hit WOT doing 80kmph it will smoke for a few seconds around 2200 rpm . ITs using 3 litres in 4 -5 thousand kilometres seems like a bit much.
