Installation Notes and Tips

Verify that the vehicle uses an oil breather cap and does not have an oil filler tube before ordering. Confirm the PCV valve opening size and compare the original cap style to the replacement part number 10071. Fitment includes many Ford, Lincoln, and Mercury models across multiple years, so matching the exact application notes is important.
