Changing oil...grrr!
Mikep328:
Well...now I'm more confused. I was looking at the shop manual a few minutes ago and on page 19 there is a diagram that shows a "collar" (Item #8) on the oil filter bolt. But the picture of the oil filter assembly in the Honda parts manual does not show a collar There was no collar on mine... is there supposed to be a collar there or not?
K2-K6:
Doing them up....I hold the filter housing and "rock" it back and forth as far as travel on location tab allows, you can tighten gently to then feel the faces just start to touch when compressing the O-ring...then go no further than that, literally only just touching as there's no point in squeezing the ring any further. Always stay dry this way.
I've only two snap on socket (bought years ago for these when tool quality was somewhat poorer design) 12mm and 17mm six sided for oil filter and tappet caps, neither have ever damaged the flanks.
Good results at decent cost currently is "US-Pro" equipment.

The 350/4's have a collar as the oil filter housing is a lot larger. It's not fitted to the 400/4.

They are expensive so I only have one atm but the Snap On Flank drive sockets & ring spanners are brilliant - I believe they have now brought out an even better version based on similar engineering design.

Thanks, NJ re the collar. I would have thought the service manual, since it's for the 350 and 400 fours, would have noted the difference in the 400 section that shows differences between the two but it doesn't.
New washer was delivered a few minutes ago; new 17mm hex head bolt wasn't so I guess I'll remount the old 12 mm (now 11mm) hex head bolt and keep the new one for a spare when it arrives.
