This TSB article is being republished in its entirety to include 1994 Thunderbird/Cougar vehicles and to reflect a change in the oil pump service kit part
number.
ISSUE:
The use of engine oil with higher than specified viscosity (5W30 / 10W30) may cause oil filter "ballooning" and subsequent loss of engine oil. Higher
viscosity oils may cause oil pump relief valve bore wear. This causes the relief valve to stick, resulting in excessive system oil pressure and a blown oil
filter.
ACTION:
Install an oil pump service kit with a revised oil pump and associated gaskets. This desensitizes the oil pump to higher viscosity oils to preclude potential
oil filter "ballooning". Refer to Instruction Sheet # 6490B, included in the kit, for the installation procedure. Refer to the appropriate Car Service
Manual, Section 03-01, for any additional 4.6L engine information.
The oil pump service kit (F5AZ-6660-A) includes one of each of the following components:
^
Oil Pump

Front Cover RH Gasket
