Gasket Kit Help..What is everything?
« on: April 14, 2015, 10:27:33 AM »
Hi All,

I am working on my engine rebuild and my kit contains all of gaskets/o rings needed. Problem I am running into, they aren’t identified! I have a general idea of what some are but some I don’t know, mainly the o-rings

Can anyone help identify/confirm my predictions below?

91303-035-000 - O-Ring 11 x 2.5mm - x3—Valve oil control at engine base, but why 3?
91319-323-000 - O-Ring 6 x 3mm - x4--?
91301-200-000 - O-Ring 10 x 1.6mm - x8—Valve guides (wont use)
91301-323-000 - O-Ring 5 x 2.4mm - x2 – Valve oil control between jugs and head

I had the same problem, suggest you measure the O rings to ensure you have the correct O ring for the right part.

Thanks, I intend to measure them to identify them. However, I still need help identifying where they go once measured....

I know this is an old topic, but I was just trying to figure out the answer to this problem.

There are three (3) 11x2.5 o-rings (91303-035-000) on the crankcase, because two of them go around the two center-rear cylinder studs. 

The third one is the seal for the oil path plug cap on the left side of the crankcase, near the base of the #1 cylinder.

Incidentally, there are two more o-rings just like them, on the same two cylinder studs, but they go on top of the cylinder block.

(For some reason, my "complete" gasket set only had two, when I needed at least four, maybe five if I were replacing all of them.  To make it even more confusing, Honda used four different part numbers for this o-ring.)
