Alt belt rubbing the lower T-belt cover? Or is the counterbalance belt tighter than a banjo string? If you can IDLE the engine you might go around using a long screwdriver as a stethoscope, to listen for noise. Check the valve cover to see if maybe there is a way loose valve, and also put the screwdriver at the dist where it goes into the  valve cover. Rod knock noise is most apparent when you lightly go on and off the gas quickly. Main bearing knock is a heavy noise and can usually be felt by putting your hand on the block down low. _____________________________ This post was made by a REAL Hondadude, not the wanna be Honda_Dude 85 Yota pickup 235k miles "never say die" 22r engine. 92 Acura Legend 70k miles.

If the journal has slight scoring you may be able to clean it up a bit with a 'belt' of fine emery paper or cloth looped over the journal and rapidly pulled back and forth. You wouldn't need to entirely remove any scoring (nor would it actually be advisable to do so), just any high spots, so long as the majority of the journal width wasn't damaged. I'd also be checking the big end eye to make sure it was perfectly round (or round to within spec, whatever that may be). If this doesn't work then at least you gave it a shot, but there's a good chance it won't work if you don't know why the bearing died in the first place. It could just be that the bearing was worn out with too large a clearance and you had metal to metal contact as a result (in which case the other bearings are not unlikely to be close behind), or could be a blockage in an oil gallery perhaps? If so and the blockage is still there then you may just wreck the new bearing. best bet would be to pull the crank out and check it properly, but then the engine has to come out etc etc. Good luck!

They would be able to tell you if they can turn it and use a bigger bearing. You did keep track of where each bearing cap came from, and mark them appropriately didn't you? If not then you probably ought to just get a different motor. _____________________________ 93 Accord LX 4Dr 2.2EFI MT 210K Miles 32MPG mostly short trip in-town driving.

Personally I think you have two options, get the crank journal(s) ground undersize and fit appropriate bearings, or a replacement motor. I'd think a replacement motor would be the path of least resistance, depending on costs... (in reply to kingss) Post #: 8

Then reinstall connecting rod, normal size bearing w/ appropriate plastigage to determine tolerances. This may allow selection of oversize or normal size bearing to work. Plastigage should show how much OOR is in the crankshaft journal. There are specs on allowable tolerances. If you can meet those, it should work. I tried this on a Dodge engine, but tolerances were too bad. Journal looked much worse than yours w/ large circumferential grooves due to bearing rotation, blockage of oil passage, and severe scoring. good luck _____________________________ See you down the ROW 1994 Accord EX (in reply to WheelBrokerAng) Post #: 10

RE: need help and options 90 accord knocking noise - 3/20/2008 5:24:04 PM    TexasHonda   Posts: 1507 Joined: 2/18/2007 Status: offline It looks pretty good. How does it feel smooth, slightly rough to drag your finger nail across the journal width, or bumpy feeling? If you can get some plastigage, you will know better whether it will work or not. Journal OOR is 0.0004" and connecting rod-journal oil clearance limit is 0.002". Pretty fine tolerances! It would be easy to pull one other bearing and check condition. If OK, reassemble. If it works it'll probably work as well w/ 5w-30  and 20w-50. good luck < Message edited by TexasHonda -- 3/20/2008 5:36:54 PM > _____________________________ See you down the ROW 1994 Accord EX (in reply to JohnL) Post #: 12
