Anyone here ever re-bearing a Miata from the oil pan? No so bad on a Chevy 350, but don't know if this little 1.8 can be done in a similar fashion?
Thanks

Also, if it spun a bearing, the crank will be scored and require machining, you can't just put a bearing in it and expect it to live.

You can't get the pan off without pulling the motor or dropping the sub-frame.

If you just r bearing without complete disassembly and through cleaning, it will not make one session. Don't ask me how I know Throw the oil cooler away, YOU CAN NOT CLEAN, if you use, you will be doing this again.

I was really planning on making a local event at the end of the month. Don't have time to pull motor and do a full tear down. Looking at finding a local used motor in the Houston area or doing a quick fix.

You're going to have to do an r&r if you put Jim's crate (or any long block). Even if you do drop the sub frame and try to do it in frame there is a pretty good chance of it ending badly. A quicdk fix could grenade the block pretty easily. You'll need at a minimum new bearings and crank machining. And it's a good idea to check your main bearings as a whole, pins and rod bolts, at least in the cylinder that spun. To do it right you'd want to tank it to make sure you get any nasty bits out. If you are time crunched get a known good long block. If I were swapping I'd do either one I could hear run (but then that's another removal) or Jim's.

I figured I would have to do the same for any engine I get used to insure it would last also.
From comments it appears I should look into a new oil cooler? This is something I have been wanting to do for my first time, so I am kinda looking forward to it.
Thanks for all the help.

I just finally came to the realization I would not make my event (in this car), and that a quick fix would ultimately lead to worse problems. I ordered a rebuild kit to include rod, thurst, and main bearings, pistons, rings, and all gaskets and seals. When I get the time I will pull and completely dissasemble. The block will get dipped, crank checked, and head decked. I have a machine shop linned up. Hopefully the process goes smoothly and I have a practically new motor when I am done.

There is a huge difference in machine shops... Don't go the cheap route, it isn't worth it. Make sure the bores are round within .0002, you really need a torque plate to do a good job. Use the specs in the book for bearing tolerances and you will be fine. Hand the shop the rules on the head, a good machine shop can do it easily and accurately.
Good luck

What do you guys do when the bores get too big? Since we can't oversize do you sleeve them or do you just get another donor block?
