when i pull the engine to do the wrist pin bearing if that is the issue and cylander is not scored, would it be a good idea to do all rings, rod bearings, and hone the cylanders

 

shoot yeah, your that close i say do them all if you can fix #5 reasonably. thats what i would do.

 

my brothers are pullinh the engine this weekend completly out so we can start tearing into it to see what exactly is cuasing the knocking but honing and rings would be my best bet with new rod bearings? if cylaner is not scored of coarse. also what size rings am i going to need since i am not boring it just honing it. just standard not .020 or higher

 

If you are just honing put back in what it had..same size. Check your piston oiling nozzle if the wrist pin bushing is bad on that cyl. If you have high milage you may want to check everything out while you are there.

 

that was the plans

 

well got the engine out and it looks like someone took a damn chisel to the cylander wall on the #5

 

Can bore and sleeve the cylinder, but what's to say the others are getting weak.

 

im doing all 6 while im at it. i thought cummins didnt have cylander sleavs since its a cast block. if sleavs and you just re-sleave it instead of boring it?

 

cummins is a sleeved block... or the one I just tore down is anyway. correct me if Im wrong someone.

 

theres ben alot more guys tell me its a casted block with no sleaves than there hasnt been cummins97 just rebuilt a 12v and it wasnt sleaved
