If its loudest at the filter housing, could it be the plastic cage inside the filter housing is broken off?
You know that plastic cage inside the filter housing that holds the oil filter in alignment? That cage can move around and break off.
Good work on fixing the oil filter.
In your video I noticed your vacuum cable clip was broken next to your oil filter housing.
Here's the URL to get a new one.
Same here, if too much TQ is applied to the filter cap it's not going to crush the filter, the lip on the cap will bottom out on the filter housing before you crush the filter. anyway... last week I blew an oil cooler line on my N54, while under the hood fixing that I observed that same noise that yours made. I changed my oil the other day, so now that I just read this I had to go check, sure enough.. the noise is gone also.:dunno: I guess I'll have to pay more attention in a couple thousand miles and see if it starts making the noise again.I would not agree though. It wouldn’t matter much if you torque to 17 or 30ft/lbs.
The TQ is insignificant, the oring is what seals the cap. the TQ spec is for the oring, not the filter. I agree that the cage in the cap doesn't normally come off and if the cage is not seated all the way in the cap maybe some damage could be caused but.. while looking at the filter full screen it looks normal to me. the filter has a slight twisting friction applied as you install the filter into the housing and it gets tight, if it wasn't tight on the top and bottom it wouldn't seal and filter properly. the filter is manufactured with straight pleats, then it's twisted to seat it into place where it spends the next 3000-7500+ miles with hot oil running through it. then it's removed from the housing and the pleats don't straighten all the way back out. That's what I see, that's how my bmw's have looked, my volvo looked and my wifes van's look.You say over torque-ing the oil filter cap doesn't compress and crush the oil filter element. If that is the case, explain how did his oil filter get compressed and crushed?
