My Truck is using Oil, but it’s not on the ground?  Doesn’t necessarily mean you need a rebuild….

Losing oil and you don’t know where it is?
Check your turbo on the pressure side and the exhaust side .
Can be a disaster -the exhaust can be a fire!!
And pressure side can blow all the engine oil into the engine until you run out and you can’t shut it off!!

Check the oil n clean out the intercooler
Or your fresh turbo will push the pooled oil in as soon as you spool up.
