Do you have oil consumption or overheating problem in your truck?

blue = oil
white = coolant

Check,or have compression Test,Dry+Wet.If there is diffrence in wet readings,then you need to replace,piston rings.
I can say its better to rebuild the engine.

If there is puff of smoke,while cranking,then you need to remove cylinder head,do valve job,and must replace valve guides/or valve guides seals. but before throwing dollars,need to find the root cause first. piston rings and valve guide seals are the only cause of oil consumption. Hope you got it.
