I had it changed prematurely because I wanted to see inside the filter since it was installed when I had the IMS, RMS, and clutch done.

I use him for stuff like mounting tires which is what he was doing when I told him to go ahead and change the oil.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

19 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Had my oil changed yesterday. I bought a MAHLE filter off Pelican parts for my 996. Part number OX 128/1. Check out the pics of my old filter and the filter I bought. You can see they�re both MAHLE OX 128/1 filters but the new one I bought obviously has a hole that is smaller in diameter and my Indy shop had to use a different filter than the one I gave him. Can anyone explain this?

POST 2Original post

Quotes source post: 16999036

Because the old one was pressed fitted in the canister. The hole is a type of seal and over time the hole naturally increases (i.e. stretches).

POST 3 / ORIGINAL POSTEROriginal post

Quotes source post: 16999047

Is �pressed fitted� a fancy way of saying my Indy mechanic didn�t apply enough force when trying to install it?

POST 4 / ORIGINAL POSTEROriginal post

Quotes source post: 16999047

Don�t know it matters but that old filter is only about six weeks old. I had it changed prematurely because I wanted to see inside the filter since it was installed when I had the IMS, RMS, and clutch done.

POST 5Original post

Quotes source post: 16999047

I think this is correct. On the new filter run your finger along the inside edge of the hole. It is just a seal.

POST 6 / ORIGINAL POSTEROriginal post

The good news is he was able to get a Purolator L25316 oil filter on there which, according to Purolator, is also an exact fit for the 996. MAHLE should write on the box, �MUST JAM THIS BABY ON THERE WITH EXCESSIVE FORCE.�

POST 7 / ORIGINAL POSTEROriginal post

And this was a fantastic sight to see. Not even a speck of metal in the old filter.

POST 8Original post

Or get the LN spin-on oil filter adaptor and spin-on type oil filter. A spin-on oil filter is better, especially if you get one with no oil filter bypass in the filter. The canister filters have a builtin oil bypass that weakens with age. So, always a good idea if you're going to stick with it, every 2-3 oil filter changes replace the entire canister. You can get one from Porsche for around $29.

POST 9 / ORIGINAL POSTEROriginal post

Quotes source post: 16999123

Thanks DB. I�ll look into it for the next one.

POST 10Original post

Quotes source post: 16999125

It seems exceedingly wasteful to replace the canister every 2 to 3 changes, they work properly for many many years. Spin on isn't better, other than it lets you do the ims solution. I wouldn't jam the new filter on, as you can crush them that way, but if you turn it as you push it on it goes on easily.

POST 11Original post

While I accept your argument, why not error on the side of replacing such a cheap item? If the spring gets weak, you are passing unfiltered oil through your engine. 2-3 oil changes is close to 15,000 miles, and there is a lot going on in there. Safer and better to just replace it. I believe for $29 you get a kit, a new canister and filter. I never did like that plastic canister! Seems a weak point in my mind.

POST 12Original post

Quotes source post: 16999187

If the overpressure releif valve fails and you aren't alerted to this by the oil pressure gauge being pegged at max your engine is toast anyway. If the engine is functioning properly, you will know if the valve is open, and there really isn't a lot going on in there. These have been used for decades and even at 100k miles I wouldn't expect to see a failure. Why add to waste? As far as the plastic, plenty of plastic has a higher tensile strength than steel. You can crack them through overtightening, but other than that I've never seen one crack on any car. Every now and then a spin on does fail and dump, but honestly either system's catastrpohic faliure is so rare it isn't worth considering. The real purpose of spin on filters was to make lube jobs quicker and easier.

POST 13Original post

Quotes source post: 16999123

Could you please post a picture of the canister with the bypass valve? I have never noticed one in the canister.

POST 14Original post

Your post prompted me to compare the Porsche oil filter to the Mahle filter. Both have a 25mm center hole and are positively identical except for the Porsche part number replacing the Mahle name. Mahle filter at FCP Euro $9.95 Porsche Filter list price at dealer parts counter $26.12 Porsche is such a rip off for certain parts such as this oil filter. Both install just fine. Perhaps your tech wanted a (poor) reason to reject the oil filter you provided him.

POST 15Original post

Quotes source post: 16999099

I just used the same Mahle filter a couple weeks ago for my oil change. No excessive force necessary. Not sure what your tech is talking about. Edited to add - for those of you that aren't aware, rockauto.com has great prices and fast shipping for oil change supplies.

POST 16Original post

The real question is not what oil filter do you use, but what type and weight of oil do you use? C'mon now...post it up...

POST 17 / ORIGINAL POSTEROriginal post

Quotes source post: 17000624

oh you did not just post that! Nooooooo. he�s a buddy of mine and only charged me $15 for the Purolator so he�s not trying to screw me. Didn�t even charge me for labor, just cost of the 0w40 (yes, I said it) at $7 a quart and the filter. He told me that in his line of work if you have to force something on there it�s better to err on the side of caution. And that MAHLE filters should come with a rubber mallet after I told him it indeed was the correct filter. He also said the Purolator fit perfectly so 🤷‍♂️ . His shop isn�t a Porsche specific shop. I use him for stuff like mounting tires which is what he was doing when I told him to go ahead and change the oil. I have a certified Porsche and Audi tech buddy that does the more complex stuff on the side. He�s doing my engine mounts next weekend for only $100. Which isn�t complex but he has access to a lift and I don�t and I�m not using a Jack to lift my engine to install the mounts. That�s a little scary to me given my lower skill level.

POST 18Original post

I would go ahead and replace the Purolater filter with a new Mann or Mahle filter ASAP. Just my $.02 worth advice.

POST 19Original post

You are comparing the holes of a virgin and the one that has been jammed and used.
