For starters, these are just pictures of some weird issues in Cylinders #2 and #3 that I’ve never seen before. Photos of Cylinder #1 provided for reference.
1994 Mazda Miata engine with 180,000mi. Rebuild due to burning lots of oil. Found the oil rings on all four pistons to be seized.
I may update this post in the future with more info/pictures to make it a real post, rather than just a placeholder to share images.
Good looking cylinder #1

Hi Martin Your dad delivered a 1990 to me a couple of years ago . the body was a little rough . so as i do tore it down to the bare bones . i had everythig except the motor apart .the hardest thing i did was install a fram mounted roll bar and maybe the new top the direction for the top were not to good .
i see the photos No2 cylinder got some issues . Check for water (coolant) cracked head gasket etc. a good rebuil shop can bore an sleeve it for you i think .
My new problem is there is a lag in throtal responce just off the idle and ahard off in the same area . had new throtal postion sensor and mass air flow box installed at the same time . the parts had a core charge and were returned so i could not do a part by part change over to isolate a troubled coponent.
Teck said it was drive train slop . i fired his @##$$%^&& dum him !!!
