Mazda 3 2.3l rod knock

we'll see how this goes

[@wilsonmaingrette715]

have its not gonna be easy..its a spun bearing so ur gonna have to change the rod sand the crankshaft if ur not gonna change the rod then at least sand the journal smooth then add the new bearing chk ur measurements because u just might have to get 0.25mm undersize rod bearing

Considering buying a 2.3L with this exact issue - what did you end up doing? Doesn't look like the bearing replacement did the trick...

[@cookiecookie3954]

The balancer has to be up with top dead center I'm doing this right now to mine

[@wrestle_dream_]

Did it work

[@KollynJ]

Did the engine last?

I wouldn't waste my time rebuilding a 2.3 did it twice, these engines have a design flaw, used oil

[@MrHevelifter]

Ever change out the pistons?

[@glassman7777]

Did you ever figure it out?

[@jfieser]

Did you replace cylinder 2 and did the noise go away?

[@jasercandales1455]

Did replacement of bearing work or did you still engine problems

[@frankf4428]

No it didn't work
