I got this motor off my friend after he took it out of his FC and it had a blown coolent seal in it with TII housings, two peice atkins seals a rebuild and with 10,000km. took it apart and it wasnt a blown seal. the plate face was broken.
i got pics off all this but my main question is that are the housings still good?
plate

housings

 

Hard to tell by the pictures, but those lines above the trailing spark plug hole dont look great at all.

 

The mark above the trailing plug doesn't look like anything an apex seal or rotor would make, see if it will wipe off. Post pics of the area between the plugs and the exhaust port. That's where most of the edge chipping/wear occurs. Run a fingernail across the lines around the exhaust port. If you can feel them, I wouldn't reuse the housing.

Judge Ito has a repair method he uses on that part of the coolant ring groove that has fractured out. Search the 'Engine Building/Porting' section over at NoPistions.com.

 

Clean the housings with some gasoline and a rag, then post more pics.

 

lol guys u can see that the funny lines above the spark plug hole are just marks in the layer of soap or whatever it is, caused by him feeling the score marks with his fingernail :P Nothing too fret over

 

ditto.

 

You do realize that I have taken apart ALOT of engines and have found the same marks in the same spot on housings that are actually grooves and the housings are not useable.

 

I knew that was a fingernail mark. Lol I've done the same thing myself to check score marks.

That broken section on your plate is fairly common on 2nd gen engines. Planned obsolescence at work. Replace the plate and throw it back together.

 

just to let everyone know that is a nail mark feeling for grooves

 

Yep,the irons on 2nd gen/later engines tend to do that,especially if the coolant isnt attended to regularly.Heres a good article about the same problem........
