ISSUE
Some vehicles equipped with the Romeo built 4.6L 2V engine or 5.4L 2V Windsor and 5.4L Supercharged engine may exhibit an oil leak or oil weepage
from the cylinder head gasket at the right hand rear or the left hand front of the engine. Oil weepage is not considered detrimental to engine performance
or durability. An oil leak may be caused by metal chip debris lodged between the head gasket and the block, chip debris between the cylinder head and
the head gasket, or by damage to the cylinder head sealing surface that occurred during the manufacturing process.
ACTION
Once an oil leak is verified with a black light test at the head gasket joint, replacement of the head gasket can be performed. If the head was damaged by
chip contamination, the head should be replaced. A revised "Service-Only" gasket is now released for both of these cases.
