Exclamation Oil Filter Assembly - Plastic parts broken (2011 GC 3.6L)

I changed my oil over the weekend (as i have done many times) and as I was setting aside the removed oil filter cap (with the used oil filter attached to it) I heard something 'pop' from the spring assembly that is part of the base assembly the filter cap screws onto. As I looked back into the filter base assembly area I had just removed the oil filter from, I noticed a part that had been 'ejected'. Upon further investigation, I found the lower section of the part still encased in the centre of the spring. I have attached a pic of the two parts I recovered (also another pic that shows them put together to make up the intended single piece). The plastic part(s) appear to have 4 'clips', so I assume this was at one point held in place perhaps in the centre of the spring that is secured to the oil filter base assembly? Seems stange for such a high activitiy space under pressure (i.e. the spring) to be plastic and also for the plastic to degenerate to the point of breaking after a mere 57,000kms.

MY QUESTION: What is this part? Is it perhaps leftovers from a prior oil filter? I have used the FRAM filter since doing my own oil changes, but before that I assume the shop may have been using the MOPAR ones? On the FRAM, there is no similar plastic piece that would have been left behind from a prior change. I have looked up some diagrams of the assembly on-line, but none provide me enough detail to see if this plastic piece is part of the engine assembly or a left over of a prior filter.

btw... I think there may have been a washer that was part of this rouge assembly that sprung free as well, but not sure if that may have been a shadow I saw down in the depths of the filter assembly base, so hoping not, since I did not recover it. Wondering if the plastic part may be part of a pressure releif valve or similar function and is part of the required parts? I drove it today and nothing seemed out of ordinary, but wondering if before heading on a longer drive this is something I need to be worried about?

There is a plastic tube attached to the filter housing that the filter goes over. Your pieces look different. Have you verified your housing looks like this with the filter removed?

Re: Oil Filter Assembly - Plastic parts broken (2011 GC 3.6L)

My housing looks similar to what you are showing here (from what i can remember). You have a picture with the engine cover removed. I only had opened the round access opening and viewed from that perspective. Also, the spring in the centre has nothing stopping you from looking down the centre of it. Your picture appears to have something on top of the spring, but does not appear to be what I discovered broken apart in mine... unless there are additional parts that have either disintigrated or have now fallen into the filter base assembly and are going to start clogging up my oil passages. If that happens, not sure how Chrysler can promote this as being something aligned to DIY... they have created a bit of an issue that nobody would be expected to consider in a routine oil change.

What spring? That is a plastic tube with slits.

If you are concerned about what is inside your filter housing:

Pull off the engine cover (it just pops off) & make sure it looks like the picture I posted with no other debris in the bottom and re-install.

The plastic tube in the center would prevent and larger pieces from being sucked through the oil passages.


Edit: After looking at your pieces more....it might be from inside the actual filter but I am not positive. I would just check your filter housing, put a new filter in there and let it ride. If you wanted to be extra careful you could change the oil as well and inspect the fluid that comes out for debris but since the pieces you posted are so large I don't think this is necessary.

Re: Oil Filter Assembly - Plastic parts broken (2011 GC 3.6L)

Thanks. I actually thought the centre 'coil' was a spring as it does seem to be a pressure for me to get the filter back onto the base, but that could be more the threads being tight screwing the cap back to the base, so I may have just 'assumed'. It is a bit confusing as far as the picture you provided as it appears there is something on the top of centre plastic 'tube', but it does not appear to be similar to the part that I have. I am also thinking my part could be remnants of a preior oil filter now, but then I am wondering what is on the top of the centre 'tube' in your picture since mine has nothing... you can just look straight down the centre to the base of the 'tube' which is attached to the oil filter base assembly? I take your point that perhaps just go with the fact that all is fine, but the missing centre piece (which appears in your pic) is now making me wonder...

Re: Oil Filter Assembly - Plastic parts broken (2011 GC 3.6L)

That's not part of an old oil filter it is part of the 009erb engine oil filter adapter/cooler. From what my dealer said as long as it was just the plastic dimple that was broken and not the center column then you are good other wise you need to replace the whole assembly for that one part. Unless you could get one from a junkyard out and reinstalled without breaking it. The plastic gets brittle from the high temps and breaks easily. Might be why they redesigned the newer ones with the centering column built into the filter so it's replaced every oil change. Hope this helps.

Those parts look like from a previous filter however within the cap is a spring that is retained by a round retainer. Cap has 4 clip type fingers that the retainer snaps into spring in between.. You must install this retainer by compressing the spring with the retainer so that it snaps back in and is retained by the fingers (I use a 24mm deep socket) making sure the fingers line up with the retainer openings then install the filter over the retainer. The filter has a "nipple" tip on one end. This end ALWAYS goes down into the engine when you install the filter. (remember to change the O-ring) Do not cross thread or torque more than about 2 foot pounds. -cadc1158

Re: Oil Filter Assembly - Plastic parts broken (2011 GC 3.6L)

The same exact thing happened to me today when changing my oil and filter. It is the plastic part and spring from the center tube inside the housing.

So did you have to replace it or is it ok to use as is?

Re: Oil Filter Assembly - Plastic parts broken (2011 GC 3.6L)

Does anyone know if it is ok to use with this plastic part broken? Also, is there a new replacement part for this? Is this potentially a dealer TSB item for replacement?

Re: Oil Filter Assembly - Plastic parts broken (2011 GC 3.6L)

I'll try to answer all these question of the post.....I too have been through this scenario and I work closely in the automotive industry. The part in question is the oil bypass valve, it is on top of a loaded spring which keeps enough pressure to seal in the top of the oil filer to not let oil pass over it until the pressure rises above which the filter can flow (dirty filter). The original design as pictured by LorneInKelowna shows that it was designed with a thin plastic cage and the tabbed locks molded onto these thin posts. Over time from unscrewing the oil filter cap and heat from the oil weakens the plastic enough that at some point when your changing the oil it will break, sometimes you hear it "crack" when your changing the filter, like I did, and wander what just happened. You should not run the vehicle with this missing, essentially you are running the engine at this point without a filter, with the bypass gone the oil flows through the easiest path an open valve and not the filter. The design was changed by Hengst to move the locking tabs to the bottom of the cage and also the cage itself was made a little chunkier. (Photo link below)

https://drive.google.com/file/d/0B5d...ew?usp=sharing

THE BAD NEWS is that you cannot just buy the little plastic valve and spring, you must buy the whole cooler assembly ~$200. As a side note Chrysler changed the supplier for these coolers based on a design change to eliminate the center valve tower that the filter slides over top of. 2013 and up pentastars use the new design which is manufactured by Sogefi.

Re: Oil Filter Assembly - Plastic parts broken (2011 GC 3.6L)

Thank you very much for that explanation ... it was very helpful to understand the function of this broken part.

Since this was re-designed for 2013 models and up, can one replace the cooler assembly with the newer 2013 design and use the appropriate filter for it? Basically is the newer part an identical replacement for the older part? Since I will have to replace the entire cooler unit anyway to fix this problem, why not just put in the newer part so it will prevent this problem from happening again in the future.

Re: Oil Filter Assembly - Plastic parts broken (2011 GC 3.6L)

As far as I am aware they are not interchangeable, I don't know the exact changes that were revised when switching to the new supplier. Perhaps a parts guy at a dealership could answer that one, you would need both revisions side by side to compare.

As far as changing the entire cooler you will not have to, the center valve can be removed and placed into your existing cooler tower, literally a 10 second fix, that cost 200 beans. Just squeeze the tabs equally around and it pops right out.
