Forums are meant to help each other, don't be sorry as I am glad you posted here!
Please send photos or detailed descriptions of what you find, it is of great help to find out where the problem is... Were these 2.3L engines? I bet the majority of people who owned these cars while they were fresh just didn't change oil on time, hence the build up.
I will let you know if I can find anything on the piston ring spec.
Hey Big Dill, thanks for the feedback. I posted here yesterday but for some reason the post never appeared. Must have gone out to the nether...
I got the specs for the piston ring gap. Still wish I could find the 10,000 page pdf of the 2010 era Mazda 3. I have the Haynes book (actually bought it for the boy, but he's not interested yet) and I have the 3000 page pdf that I got for $14 bucks. Then I found the same one for free while looking for the 10,000 page one.
I need to figure out the picture posting method here, then I’ll start posting pics. I want to build a thread for the 2.0 rebuild, but this holiday week has been hectic.. can’t wait to go back to work so the local boss doesn’t find more for me to do.
I looked through some of the photos I took during the tear down and will take some more as I finish the old block inspection. Will also include some detailed photos of the intake. I’ll have to come back here and update a post with the link. But I’m thinking too far ahead now….
Also; no. These were both 2.0 engines.
