Condition

Some customers may comment on excessive engine oil consumption. The rate of oil consumption described may usually be around 0.946 liter (1 quart) of engine oil in 805 to 1125 km (500 to 700 mi). This usually occurs on low mileage engines.

Cause

This condition may be caused by a nick in one or more valve stems.

Correction
Important
If one or more damaged valve stems are identified in one head, BOTH heads MUST be replaced.

tell the dealer to look at this bulletin #07-06-01-007F and then get loud when they try blowin smoke up your ass. tell them you want each valve stem examined thoroughly. fully disassemble the heads, on or off the truck, and complete inspection of each valve stem. if i were you, i'd get under the truck and look for any large oil leaks too.

thats dooin your homework.. BOOOM!
