SO i changed the oil the other day and now its making this wierd clicking/rattling noise like marbles in a metal can. It kinda sounds like a Ratchet. It seamed to become more pronounced as the engine warmed up. I only let it run for maybe 5 minutes because i wasnt sure what i was hearing. This noise is comming from the Oil Filter area. There is a very slow drip leak from the the area where the Filter attaches. Even thought the filter is the Correct size and screwed on tight. I filled it up with Oil before i put it on. I use Mobil 1 synthetic 10w30 which has been used in it since it was new. You can hear it in this video. It doesnt seem to rise and fall with rpm. It didnt make this noise before i changed the oil so Idk whats goin on. Any ideas?
if you click this pic it should link to the video

Well, your filter isn't supposed to leak. I hope it isn't the wrong one. My computer can't play the video, but your description sounds kinda bad.

Well autozone told me there are Two different model numbers for this car. The first one they gave me was about half as tall as the one i had on there. I called them and they inssited it would owork.. well i Took it off because of this noise and went back and got the Other larger filter and installed it. This didnt get rid of the noise. I didnt have time to before work to do alot of inspection this afternoon, but i cant think of anything on that side of the Engine that would be a noise maker, i Guess that flywheel. or maybe the Distributor
maybe one of these links will get you there

First thing I would say is try a different brand of filter, preferably one of the NAPA labels. FRAM filters are poor construction and its entirely possible that the inside is buzzing

OK i went and got a Napa Oil filter and put it on and the car still made the noise. But the leaking did stop (autozone does indeed suck). Anyway i probably forgot to mention, when i changed the oil i also changed the Oil pan gasket and while i was there i changed the Tranmission Pan Gasket and Filter. WELL, the new Trans filter looked a bit different than the original but they insisted it was the correct part and that the manufacturer just had a slightly different design than the GM part.... Im pretty sure that noise was a pump running dry inside the Transmission (since its on that Side) and when i attempted to drive it around the block this afternoon would not engage or move when i put it in Drive. Apperently this new filter isnt picking up the fluid for whatever reason. In the pics, the filter with the Grid Design is the Original GM part. Im temted to just put the old one back in since i wasnt having any problems except for the leaking gasket....The new part also has this gold ring that slides over the tube.. The Orignial Gm part does not, and the new part would not fit unless i removed that ring.

The ring off the original filter is probably still stuck in the trans. You better look it over closer, that is a common mistake.

I think the Ring is in there. If it is it sure isnt comming out. WHat i had done was just removed the ring from the new one and then the new filter popped right in. But i decided to put back inplace the old Gm filter since the only transmisson problem i was having was a leaky gasket. I took some pics., The Replacement part was just barely fittable, it really didnt look right in there. Ill post these pics.


it plugs in the hole at the top left of this pic. At the top you see this curved metal tab that presses down on a flat metal tab. under the flat tab is a hole. idk its function but im sure its important.

here you see the originam GM Filter in place. It is shaped to go Around the metal tabs.(now seen at right)


Here you see the New Duralast filter in place. It is the wrong shape, it covers these tabs and the filter is soo much thicker/taller than the original, that when everything goes back together it actually firmly presses in on those tabs rendering them non functional.
I ran out of Day light yesterday, so ill be going back out to work on it this afternoon and see if this fixed the situation.

just got Back to a computer, i put it all back together with the original GM filter and voila,, it runs. and i mean it RUNS. The noise is Gone and the trans shifts seemlessly. this is the first drive since doing the Oil, trans, rebuilding and cleaning the filthy TBI, hooking up the smog/air injection system and replacing every Vacuum line under the hood. also new Spark plugs wires and distrib cap/rotor....This car has Never had this much power, or ran this smooth since ive been driving it. i know the 4.1 has a rep for being an underpowered slug (which this one Was) but it definately has some Punch now. it all took some time (most of the time fixing what i messed up) but it was well worth it. next project will be a new cat converter and finding the exhaust leak. ill see if i can get a video of it reving up this week.

There are also many mistakes in the aftermarket parts books during our years of Devilles. One common problem i find is the books will often list the part for the RWD Deville and the parts guys will insist that this is correct. (Really can't blame them as all they know is what is in the computer) The days of knowledgeable parts counter personnel are long gone.
Whenever possible i look up the original GM part number in my factory parts book and see if they can cross reference this to verify i am getting the correct part.
I personaly believe that at one point a data entry specialist was given the job to enter all of the 85 86 etc parts in a master computer database. Not knowing the difference in the FWD and RWD models, (remember they where named the same way) mistakes where made. These mistakes seem to have filtered down through many parts books used by many manufacturers. Just my opinion.
