Engine is damaged - not an IMS failure!

I guess we will never know how much money "they" have saved people due to the preventative maintenence option "they" provided!

I don't think the engine would be 'toast' as I believe that the Guardian throws up a red light when metal filings or small pieces stick to it. The Guardian is situation in the oil sump I think. We can look for our own filings (which i do) by cutting open the oil filter and inspecting it during an oil and filter change. Then if the slightest piece was discovered, it would be time for an IMS bearing change. To discover plastic bits could be better than metal as then the plastic covering around the bearing would have broken, allowing much needed oil to lubricate the bearing properly. A sump drop would be in order to clear out the remaining plastic plus a new retro fit bearing to be on the safe side. So you are partially correct in saying that the Guardian does Nothing (only display the red light).. I think thats how it works. The time between oil changes is the most unprotected time when the Guardian could save our bacon. Sometimes I wished I had never posted to this forum. I didn't know anything about the fault on the 996 when I bought the car. Thanks to you blabbermouths haha... After saying that, I have learned so much and saved a ton of cash by doing my own work on the car preventative diy work. I gain lots of info everytime I read the forum so here I will stay. Thanks to you guys. You know who you are. Macster especially to mention just one Gem.

Just came back from the shop - he said he checked the codes when it arrived and they indicated it was firing on only two cylinders when it stopped. They then pulled the end caps for the cams and the cams were in the wrong position relative to each other, basically indicating internal carnage. He felt it wasn't worth the expense of a teardown just to confirm. They have dealt with three others recently. Can't see why he would bull**** me because either way I would get the engine.
Trapperdog: the interior of the engine destroys itself - no need to look at the bearing itself.
996_North - that's what I was thinking - this issue was for low mileage cars ....
Hurdigurdiman - It's a respected shop in town. I'm not pulling your plonker - I'm into a bottle of scotch on a Monday night.

Good lord but some of you are just ignorant monkeys with laptops.
Let's try this real slow for those of you in the peanut gallery... IMS failure happens. It is not a sham invented by mechanics to gouge customers, nor is it a unicorn-like phantom that no one has ever really seen. Not all engine failures are IMS failures. The actual numbers are literally impossible to nail down, but seem to be somewhere between 5 and 10% of cars... Enough so that preventive measures like the IMS Guardian and the LN Engineering bearing upgrade are a sound investment.
And another thing... Throwing out your Internet hoax conspiracy theories while a Rennlist member is looking at a huge bill and the potential loss of a cherished car is just downright thoughtless and cold.
So please just go hang out on TMZ or wherever else the internet collects the lowest common denominators and leave this place to serious discussion and information.
Peace out.

This like a republican / democrat debate. 5 to 10% IS crap. The OP's car is in trouble but I don't believe the xxx is the reason. I would really take the car for 2nd opinion. Let the lemmings jump off the cliff.

I had a a thrust bearing failure, and when I replaced my engine I put in both the IMS Guardian and the upgraded LN Engineering bearing, because the 996 sitting in my mechanics bay next to my 996 had an IMSB failure, and the Porsche in the bay next to that was a Boxster with an IMSB failure with less than 20K on the clock! What a friggin wake-up call that was to see two Porsches laid-up with IMS failures. IMSB failures are obviously happening, maybe not to me but it is happening to other Porsches around me.
Peace of mind is what I have for the $600 i put into it... just peace of mind- not just for the IMSB but if any ferrous metal shaving end up in my sump... I'm going to know about it before I end up buying another engine .

Granted none of us have a statistically significant data set. But some of us laptop monkeys have seen that a very small percentage of the total Porsche engine failures are due to the IMSB. Does the IMSB fail? Of course it does some time. But out of the ~10 water cooled engine failures I've seen, only one was IMSB.
WTF is TMZ anyway?

Sorry to hear about your problems - when my CPO ran out I shipped my car to Flat 6 and had a bunch of stuff done including the IMSR procedure, water pump, clutch, lifters, and some other stuff. I sleep better at night now - I just hit 20K miles on my 04 40th AE.

... We pay attention, and follow up with our friends, colleagues, and students on the cause of their engine failures.

Clearly my post was aimed at those who are stubbornly or stupidly on that river in Egypt, not at you.
