2000 Ranger 3.0

had a shop rebuild the motor, drove it 500 miles to break in, and changed the oil. Drove it 1200 miles after that the truck had no oil but had oil pressure; I figured it's normal for rings to set in so did an oil change. Drove 400 miles and down a quart and noticed oil on my intake on the pic .

Does anyone have a clue why it's losing oil

 

I assume PCV Valve is new, if not replace it

Do a compression test
All spark plugs removed first, cold engine
Test each cylinder, write down results

Fresh rebuild should be in the 165psi area on a 2000 3.0l Vulcan

Only way oil VAPOR can get into the intake is via the PCV Valve hose or Breather hose

Only place in an engine that is HOT enough to VAPORIZE oil is the cylinder wall piston ring area
Its call "Blow-by" and is normal, in small amounts, on ALL piston engines
When a cylinder Fires some of that HOT expanding gas, that pushes piston down, will "blow-by" the rings, these gases are HOT enough to VAPORIZE some of the oil on the cylinder walls and sides of pistons
This vaporized oil is hot and will tend to go up(hot air rises), and into valve cover area where PCV and Breather can pull it into the intake
The whole point of the PCV system is to get rid of the "exhaust gases"/blow-by so its not vented into outside air

Higher than normal blow-by means higher than normal oil vapor, and that would show up as lower than normal compression

 

i will do all of that excellent info
