I have previously installed a LN Engineering spin on oil filter housing.

When the IMS was done (by the dealer prior to my purchase) they replaced the RMS.

I found this - but it's used for guns apparently...

Yes 5900, although I have also used permatex "right stuff".

Not too hard to push that spring off if he was using the "drill the seal flange to allow self tapping to grab the seal and pull it." pretty common way to pull a seal with out scratching the delicate sealed surfaces.
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.

Changing my oil in my 2004 996 C2 yesterday I found a small piece of stiff wire in a zig zag shape in my oil catch.
I drained the hot oil from the pan first - all seemed normal as the oil hit the oil sponge in my oil catch pan. I shifted to removing the filter. I have previously installed a LN Engineering spin on oil filter housing. When unscrewing the filter the housing unscrewed as well. (Pretty common).
When draining the used oil from the oil catch into my old oil drum I found the wire on the oil sponge. I believe it came out with the oil filter and housing, but am not positive. Current ideas include part of the original oil pop up, a retainer from the windage tray, engine internals, maybe a clip from a connector that I knocked loose, you name it and no help from search.
Any ideas? Any one know what this is? Thanks in advance.
Thank you BOTH! I think dent removal wire would be sort of amazing and a bit unlikely - to the comment on retainer from the original oil filter housing, that was my response from my bit of research too - and so it is my hope.
I'm crossing my fingers that it is from the oil filter and agree that it probably isn't the dent removal wire!
Would love to see it in an actual oil filter as I've never come across such in all the filters and cartridges I got apart over the years.
Thanks. I can measure it but it's about 1.5" long .375-.5" "wide" peak to peak. Agreed, I haven't seen it in an oil filter but was thinking it might have been part of the original housing? I didn't actually see it fall out of the oil filter hole or the oil drain hole. It was just there. If it did come from the oil pan, and not the oil filter housing, I thought it could be part of a retainer for the plastic windage tray. Not sure, but AI had suggested it could be a retainer for a flap on the tray - of some sort. I haven't seen the windage tray for our cars so am unsure of how that sort of wavy wire would be used.
Thanks, you mean, drop the pan? The wire is not flexible at all, but does have some scratches on it. Wouldn't a bit of stiff wire like that, if it got sucked up into the oil pump cause the oil pump to make terrible noises and or die?
In my opinion if it did come out of the engine it was a straight wire and was bent by something in the engine. Oil pump, scavenger pump. timing gear, chain.
Yes if one piece came out maybe there is more. I've often said the first thing any new owner of an M96 engine should do is see what's in the sump. Can tell you some things.
Interesting! To me, it looks like some sort of spring clip that made its way into the engine and got banged up. Any work done during the last oil change? Connectors removed, etc.
The clearance is too little between the gears of any of the oil pumps to shape a straight wire into this. The gears would seize and the hex drive or the nose on the scavenging pump gear would shear off.
The mesh on the oil pump pick-up is comparable to a tea sieve, so much thinner wire gauge.
The rubber baffles are hinged using plastic rivets to the plastic box, if OEM, so not that either.
I know you JUST filled it with oil...
But I would drop the sump to look inside.
It is not difficult.
(save your new oil, filter it through a blue paper shop towel,and reuse it)

Installed an IPD GT# throttle body and Fabspeed Air intake, and Fister modified mufflers. That's it. The piece does look a little like a piece from a connector, but it would be a pretty big connector...
To your comment, it is a little banged up, the picture actually shows the clean side, whereas the other side does have a few scratches and a flat spot. I would have thought though that oil pump or other gears would chew it up pretty badly to get it into that shape from a straight wire. I thought it could be part of the Oil pressure relief spring - maybe it broke and then the spring got "squished" into the wavy shape but it's pretty uniform and only has any marks on one side.
Yes, but interestingly, in that thread there was this post:
The IMSB does not have any springs like that. Pretty sure that is from the "old" style RMS. If it was changed the "mechanic" might never notice that spring if it slid into the engine on the crank end when he was pulling the old one. Not too hard to push that spring off if he was using the "drill the seal flange to allow self tapping to grab the seal and pull it." pretty common way to pull a seal with out scratching the delicate sealed surfaces.
When the IMS was done (by the dealer prior to my purchase) they replaced the RMS. I'm wondering if my piece of wire is possibly from that RMS change. And, to that post, maybe there's more in the sump. What's the preferred gasket material for the sump, Locktite 5900?
Screen is removable from snorkel. I would just clean it and only replace if it's torn or otherwise damaged.
The oil pressure relief valve sits at the bottom of the filter housing. I see no way how a flat(ish), short coil spring from that valve could turn into that zigzag shape or end up in the sump for that matter. Replacement requires the whole housing be replaced.
Should you have meant the oil pressure control valve, then again I see no connection between the spring inside the control valve and the wire in the sump. Irrespective of that, replacing the spring yields a couple of psi oil pressure as the original one will probably have settled a little by now.
No need to replace the piston itself. The 997 chamfered 'upgrade' does nothing other than prevent squealing noise, as pointed out by Porschetech3 in his 'cheap M96 upgrades' thread.
That wire is not from the replaced RMS. The thickness of the wire is orders of magnitude bigger than that of the RMS spring wire.
Loctite 5900 or 5910 is suitable but so is any other Alkoxy-cure silicone rtv (again courtesy of PT3).
Yes 5900, although I have also used permatex "right stuff". A 1-2 mm bead is all that's needed. I put the bead down and then smear it flat to make sure there is good coverage.
Seems I have to replace the entire pickup tube and screen. Hoping to avoid that. But any opinions on the "while I'm in there" Oil Pressure Relief Valve using the 997 part?
yes. I see that and I did mean should I replace the potentially worn spring for the extra couple of PSI oil pressure. Thanks for that.
Here�s more pictures. The wire is less banged up than I thought. Just some scratches on one side and no real flat spot. You can see the waviness is not perfect. And the wire does have a slight curve overall. Not much, but you can see it in the last picture. Thin, a little flexible but not bendable by (my) hand.
I can assure you with 100% certainty that that did not come from the Factory inside an M96 engine ....
My guess is that someone threw that in your oil pan to play a trick on you ... ( a dirty trick ...lol )
And the only thing I can think of "outside the engine on a car" would be seat upholstery support springs that resemble that ..
Best post of the day! And if I found out it was a trick, not sure if I'd hug them for the relief or wring their neck for the stress.
So, do I drop the pan anyway, because it's a good idea or do I wait until the next oil change?
Yes, drop the pan anyways !! .. It's only 13 screws that are easy to get to.......Buy a new 10qt oil drain container for $10 and re-use the new oil !!
It's always good to look into the soul of the M96 engine !!!
