Ok, question time. I'm having an oil loss problem. About once a week or so i find im a half quart low on oil. I can find no visible leak where i would be losing oil,no puddles under my truck. I run Amsoil 15-40 HD diesel,and i have not done anything of high towing or hauling capacity rescently.
The truck is in my sig.
Thanks in advance for any clues

watch your oil pressure guage. check the drain tube for the turbo, old rubber= dry rot.

 

Oil pressure gauge not fluctuating up or down any more than usual. The drain tube should leave a puddle if its messin up,right?
Thanks for the input,ill check that tube tonight.

 

I would check your tailpipe, see if it's oily. If it is, it means your turbo seals could be letting oil by. Could also be coming out of the blow-by tube. Look at the bottom of your truck, especially the trans pan and see if it's coated in oil.

how many miles are on your engine after about 200,000 or so they start getting blow by

 

the Truck has 280,000 mi. on her. Transmission is a 5 speed,and i do need to check the blow by tube.....no oil in tail pipe.
Thanks for the help guys!
