In addition, all Teledyne Continental Motors engines of the above listed models, regardless of serial number, which have had the oil pump assembly or oil pressure relief valve screw and/or plunger changed in service during the period April 1, 1978 through January 5, 1979, must comply with this AD.
Compliance is required within the next 50 hours' time in service after the effective date of this AD, unless already accomplished.
To prevent the possible loss of oil pressure indication, accomplish the following:
(1) Inspect the oil pressure relief valve housing. If a yellow paint dot is evident, no further action is required. If the paint dot is not evident, remove the relief valve assembly, inspect the screw and plunger and compare their dimensions to the illustrations in paragraph (3).
(2) Those screws and plungers which conform dimensionally to Figure 2, "Intermediate Design," must be replaced with components conforming to Figure 3, "Current Design." The "Current Design" is contained in TCM Kit 642335KA1. Screws and plungers conforming to Figure 1, "Original Design," may be continued in service.
(3)

(4) Identify the oil pressure relief valve housing with a yellow dot on those valves with plungers installed in accordance with Figures 1 and 3.
(5) An alternate method of compliance may be approved by the Chief, Engineering and Manufacturing Branch, Federal Aviation Administration, Southern Region.
NOTE: Teledyne Continental Motors (TCM) Service Bulletin M79-2, Rev. 1, dated February 12, 1979, also pertains to this subject.
This amendment becomes effective March 12, 1979.
