Fellow Civic Enthusiasts,
I am now frustrated & perplexed. It appears that somebody at Honda screwed up.
I am replacing the head gasket on a 1999 Honda Civic LX (D16Y7).
Page 6-44 of the 1996 to 2000 Honda Civic Service Manual instructs to replace an O-ring that is NOT available in the Honda parts catalog.
The manual shows this O-ring going in just before the "Oil Control Orifice" into the top of the cylinder head, near the camshaft, between the head & a rocker pedestal.
The Honda part # is 15140-P2A-000.
This part is described as "Oil passage orifice assembly".
This part (15140-P2A-000) is shown WITH the O-ring ('97 and earlier models) and WITHOUT the O-ring ('98 and later models).
HOW can ONE PART number include and NOT include a required 0-ring?
Does anyone know the answer, or should I call Honda?
TIA...
Tim

 

Update: This problem has been resolved. The problem was caused by Honda withholding information. The design of the engine was changed at some point in time, the manuals & catalogs were NOT updated to reflect the change. I eventually learned that there was a "Service Bulletin" that clearly explained everything. This bulletin was NOT available to the public (me). The pending "Right To Repair" legislation will prevent these kinds of problems from happening in the future. Tim
