Yea, looks like you spun a rod bearing. Do you have access to machine shops capable of grinding the crank bearing to make it smaller and perfectly smooth? You can purchase oversize repair bearings from Mazda to fix this as it happens often to cars with low or no oil pressure. Worth it? Well, that depends on how much another used engine costs and what problems it may have. If it were me, I would try to get this one repaired but also try to find out why the oil pressure dropped so much that this happened in the first place. Be sure to fix that too or you will just spin another bearing right away. If you reassemble the engine yourself, be sure to use an anti-seize assembly compound to keep things lubricated until the oil pressure comes up the first time you start it.

Hope this helps.

I will try to get a qoute for the this, but i think it will be to expencive. as I buy a engine - this one was for sell or as spear.

I think that i did not check the oil level as I needed to.

Also somone worn me that in drift there is problem woth oiling in the Miata. but i do not think this is why it happend.

Is there somthing to check in my car ot in my new engine?

Thanks for the help
