Noisy spin on oil filter

Hello and thanks to all for the information posted on this site, I have found many answers.

I have a BN4 with a spin on oil filter conversion, I put the first 50 miles on the clock since rebuild yesterday all was fine. Today on startup I noticed a noise that sounded like a dry bearing, after listening to all the spinning parts with a screwdriver to my ear I found the source of the noise to be the oil filter.
Has anyone seen this before?
 
I'll take a guess because I suspect no one has encountered this. I doubt the noise is coming from the filter; there are no moving parts in a spin-on filter (nor in the stock canister type, for that matter). The noise is most likely coming from an internal engine component, and reverberating through the filter since the adapter is essentially a part of the block once bolted on. Unfortunately, if it sounds like a dry bearing, it may well be. But, as always, I may be full of pan sludge.

Harbor Freight sells a mechanic's stethoscope for just a few bucks. They work well and I recently used one to diagnose a failing idler pulley bearing (but not without some misdirection first).
 
WELL: try this:

Turn the engine over several times with the Ignition switch off until you see oil pressure on the meter. .Now start the engine and see if the noise has gone away. If it has you have a bearing or something in the engine that is not oiling properly??
 
Thanks for the input chaps, I realy, realy hope that the filter is not amplifying a noise from elsewhere, I will try Keoke's tip in the morning and then change the oil filter, nothing to lose, fingers crossed.
 
Make sure the spin on adapter is mounted correctly. If not, you're not oiling the engine bearings. Don't ask how i know this!:frown-new:
 
Today I changed the oil filter, while it was off I checked the orientation of the adapter plate and was able to pass a screwdriver through both holes into the block. Fitted new oil filter and the noise has gone, also oil pressure has increased by around 5 psi. I opened up the old filter, (one plaster (band aid), no sign of any debris, my thoughts are that the non return valve was fluttering. Now need to put some more miles on the clock, time will tell.
