The plug is shown on page 6-13 of the shop manual, but not identified. It looks like an oil drain plug. When I took it out, some oil drained out. Was that oil from the crank case or something else? I found the part number on a drawing at Honda Parts Direct. Part number of the plug is 90048-MN5-000.

Per parts micro fiche:
BOLT, SEALING (20MM)
90048-MN5-000
Sounds like a bolt (plug) used to seal a hole either used in machining the block or allowing access to a internal fastener. Either way if oil came out when it was removed, it obviously seals a hole in the crank case. Just curious, why did you remove it?

Only doing my second oil change on the Valk. In a hurry, looked under there, saw that plug, thought it was the drain plug. Removed it and only about a cup of oil drained out. Hum, where is the other three and three quarters, quarts of oil. NOW, I check my manual, wrong plug.  Next question, what did I just drain? Thus the orgional post.  |

Don't know what was Honda's original reason for putting the hole there. Might be a port to attach a gauge for checking oil pressure. That it what Motosens uses it for. If you get a Motosens oil pressure gauge, you have to get a oil pressure sending unit/and mount for the sending unit. The mount threads in there.   |

ptgb, and everyone else, thanks for the information! For a while there, I thought I may have left all the upsadaysium (Rocky and Bullwinkle) out. I guess there was no harm, no foul!  |

I guess there was no harm, no foul! Don't forget to check your oil level. Sounds as if you might be "about a cup" low. |

I wonder if that could also be used with an oil gauge using the small plastic hose to read oil pressure

Two days after reading this thread I was changing my antifreeze for the first time, guess which plug I took out. lol. I remembered seeing that it was a 10mm bolt in the docs. The water pump drain is 10mm, this is a 10mm Allen bolt. As soon as it started draining, this thread was my first thought.
