2007 ranger 3.0
Does anyone know if the valve & head problems were resolved for the 2007 model Ranger 3.0. Build date is 9 2006. I have 62000 miles on my truck, still runs like new. I plan to change cam position sensor at 80000. Thanks in advance for any information.

The 2.8 and 2.9 V6's had numerous problems including cracked heads and blown head gaskets and a very poorly designed oil routing scheme that often starved the topend in higher milage copies. The 3.0 was a brand new design penned after they had learned these lessons so it's generally a pretty solid motor.

Ford did have some problems with a bad batch of 3.0L OHV heads several years ago. I can only assume the issue was fixed by '07:

FORD: 2004-2006 Ranger
ISSUE
Some 2004-2006 Rangers 3.0L-2V "Vulcan"vehicles may exhibit:
- Malfunction indicator lamp (MIL) on with diagnostic trouble codes (DTCs) P0300-P0306 and P0316
- Rough running at various RPM
- Rough idle
- Misfire
ACTION
This may be due to an engine exhaust valve seat recession causing a loss of compression. Refer to the following Service Procedure to diagnose exhaust valve seat recession.
SERVICE PROCEDURE
1. Perform a power balance rest to clarify if a cylinder is misfiring. Identify and keep record of any cylinder that has a concern.
2. Perform a manual compression test with the spark plugs removed to locate any cylinder that may have low compression. Refer to the appropriate Workshop Manual, Engine System, General Information, 303-00.
3. If no low compression is found per shop manual instructions, proceed with normal misfire diagnostics per the Powertrain Controls/Emissions Diagnosis (PC/ED) Manual for the appropriate model year.
4. If low compression is found and it is a cylinder that had a misfire on power balance, perform a leakdown test to determine the source of leakage that may be causing the low compression. Refer to the appropriate Workshop Manual, Engine System, General Information, 303-00.
5. If low compression is found in a cylinder that did not have a misfire detected then proceed with normal base engine diagnostics per the Workshop Manual, Engine System, General Information, 303-00.6.
If the exhaust valve is identified as the source, replace both cylinder heads with the newly released service cylinder heads. Refer to the appropriate Workshop Manual, Section 301-01A.
