I pulled my motor apart last night after it blew a coolant seal a few months back. There was no rust on the inside thankfully but I do have a little bit of wear. I was wondering if it was excessive or not. In the rotor housings there is a little near both housings exhaust and then near the spark plugs on the other one. Also where the rotors run along the end and intermiediate housing there are marks from where the seals ran along.

So everything look good to put back together or do i need to look for any new housings?

 

here are the rest of my pictures

 

Its hard to see the edges of the aluminum housings for flaking. Any grooves on the housings? Overall it look very usable.

 

There is no flaking on the edges just those dark patches. On the intermidiate/end housings there are very slight grooves that are hardly noticeable when runnings your hand across it.

 

may i suggest getting the intermidiates lapped? they look good otherwise but it woudlnt hurt to machine just few thousandths off.....

 

Can't tell from the pics on the housings. If you could clean them up, then post, we can tell better. Can you catch your fingernail on the irons?
