My crank shaft is damaged (it's where 3rd conrod is connected to crank shaft). Crank shaft is scratshed there. Is there any possibility to repair it or should I put new one?

Depends on how deap the mark is. You can get them ground and use undersize berrings -
or you can get in hard chomed or metal sprayed then ground back down to its orginal size

The 5cyl crank is easy to obtain and they very rarely have any wear. I'd look to replace it with a second hand item. It's also worth getting it crack tested before using it in a rebuild.91 Modded 3B

I have heard that there isn't any undersize berrings for that engine. My car has about 360 hp and if I repair it then how reliable will it be? I have a place where I can get used crank shaft for about 350 EUR but before I buy it I want to be sure that I can't repair the old one.Comment
