There's seldom a repair that works. These crankshafts are very hard so they don't polish well. If you get rod or main knock you almost certainly need a new crankshaft.
Its possible to change rod bearings without disassembly this big bottom plate and remove engine in K20? I think about not much space to take upper rod bearing from rod
Cleaning the oil pan thoroughly is your first step. You will want to make sure and change the oil filter & add new oil after the job is complete. The oil filter should be able to filter out any metal that comes its way.
How many mile are you looking to get our of the cleaned up rods and crank? The clearance between the bearings and the rod/crank has increased... but that would be filled with more oil right?
nornal u have to do a full rebuild after this try Next time to save some time When a rod knock occurs u need to check all the bearing clearance .... F20c are culprit to fail on the centre mains and when u have alots of metal shaving like u have u need to look the thrust washer 50% of time when heavy clutch u have crank walk tooo Do you have any update on why no oil pressure do you find where the pressure bleed out ?
We ended up having to rebuild the lower end. The crank was bent .020 out. Went ahead and replaced the oil pump since everything else was going to be new.
hey how much do you know about then s2k motor I believe I’m running into this problem but I don’t know too much. I want to learn as much as I can. For the rebuild.
Sadly no. We are now in the process of pulling the motor to do a rebuild. We believe that the oil pump gave out and we were not getting any oil pressure.
@@ExoAutoWorksVlogs if you actually torqued down the rod caps to 18ft/lb, that's one of the problem. the manual i believe calls for 18ft/lb plus 90* turn which would be something on the order of 40-50ft/lb

This is very impressive. It saves money and time and yet the work has been done nicely.

What are some ways to be mindful of metal shavings in the oil channels of the engine after rod journal bearing failure?

Were the rod caps torqued to 18ft/lbs + 90 degrees or just 18ft/lbs?
18ft/lbs + 90 degrees
Did you install new rod bearings?

We were hoping it would allow us to move it in and out of the shop without needing to be pushed. It didn't last long though and requires a rebuild.

Is it still running no issues thru the rpm range?
Sadly no. We are now in the process of pulling the motor to do a rebuild. We believe that the oil pump gave out and we were not getting any oil pressure.

Do rod bearings wear faster than main bearings on these Honda engines?
they do wear a lot faster
k series also. I had my old k24a3 with a rod knock.
was the knock present @ idle around 800 RPM or holding @ certain RPM?
from my experience witk my k24 rod knock it appeared at high rpm and in a few minutes it was all over the rpms
also you can hear high pitched sound of metal on metal
how many miles this
160k
