KY advice on engine wear pics

Hi,
I opened up the engine last week and finally had time to clean the parts a little and take some pics. I measured the step on the side and middle irons where the corner seal (I believe) makes a groove that can be up to .004 deep and it seems to be a maximum of .002 or .003.
What is your opinion on this wear visually? If the parts are visually ok to use I will measure the wear a little more.
On the irons there is some slight pitting where the forst o ring sits. When I was removing the carbon and clean it, the pitting showed up,

No history on car, I bought it with a low compression engine. It wouldn't start unless I put oil in the spark plug holes. It's a 2004 with 59000 miles.

Thanks

May I ask a mod to move this to the Series I DYI forum so it might get more visibility for some much needed answers?


Thank you

Unfortunately, this has become a sleepy forum, and the people who would know may not be around very often.

thanks for the reply,
Just trying to see how much it would cost for a rebuild and if it's necessary to replace irons and housings. Housings would be ok but replacing the irons too, would make it too expensive for me (in Canadian dollars after shipping, conversion and taxes...)

You can't go by looks, you have to spec the parts. If you take advise from people online based on pics, you are going to have a bad time.

Thanks for the input,
My concern was that if visually it is clear that the parts are too worn I won't spec them.
From what I read, the irons dont seem too bad.
The worry that I have is the slight pitting on the area of the first O-Ring from the inside. Is that something that is relatively normal or will it cause leaks for sure?

Did not get my Mazdatrix video yet. Shipping is really long to Canada.

Again, you can't go by looks unless the parts are obvious junk. These parts look marginal but again to guess is not smart at all, that is why you see so many "my fresh rebuilt engine won't start" threads.

That's what I try avoiding to have to say: my fresh rebuilt engine won't start.
I'll mesure all the critical dimensions and see how they check-out.
I'll post back what happens but it might take a while.
On the other hand I am not sure I'd like to do a rebuild with marginal parts even if they are within tolérances (meaning close to the limit).
