OH NO!! Metal shavings in oil filter :(|

If the oil had just been changed, I would have asked to have the pan dropped. Either way, I was aware of the IMS bearing issues and decided to include that as part of the PPI.

It added very little money to the cost of a PPI and gave me some additional
confidence and peace of mind. Many of us (including me) cut open the filter after each oil change, so why wouldn't you include that in your PPI?

Just doing the filter doesn't take too long, but dropping the pan would add cost if you do it every time you are looking to buy car. And you still won't really know if the IMS bearing is due to implode three months down the road or your open deck bores or heads have the early beginnings of cracks.

I personally don't think the really scary stuff shows up in an inspection. My car has had pretty much spotless oil filters (which I inspect / cut open when I change the oil roughly every 6-7k) for the last 40k odd miles. This guarantees me nothing. The IMS might fail the next time I crank her over.

I agree Pothole, no guarantees, but it will certainly tell you if things are seriously amiss at the time of a purchase (and lets face it, haz's car was still running fine when they discovered all of the particles in the filter). So too would a small amount of metallic particles (lets say, anything more than about three very small ones), or to a lesser degree, the presence of plastic particles. One won't always be able to catch a problem before it happens, but your chances of finding a pre-existing one (or with short oil-change intervals, one that is just starting to develop) increase dramatically with an inspection of the filter.

SS Performance (specialises in rebuilding Porsche engines) quoted me $4100 for the IMS replacement. They did however recommend a full teardown with different upgrades for $11500....

Being that you're in Europe, wouldn't it be cheaper to buy a used engine from one of the many British shops doing these rebuilds? From what I understand its the best deal going on your side of the ocean.

Could be, but it`s twice the money than the IMS upgrade.

careful, it could be too late for you to be doing the IMS upgrade. I would reach out to a shop that only does m96 rebuilds like Flat6 Innovations before you make a decision. Those fragments could already be in places where they shouldn't be and can't be taken out without a tear down. It would really suck if you spent $4K only to be right back a zero after a short time on the road. I'd rather just buy a used engine from the British shops, which some on this forum say can be bought for $5K or less. I'm sure they can do the IMS swap, if it doesn't already come installed, for less than the $4K you're being quoted in Norway. Or maybe just ship the whole car to the UK.

@Perfectlap,

I agree with your logic on the floating bits….and I can sympathize with @Haz, that is my problem too. I caught it early but cannot trust the bits will not come back to bite! However, the UK engines from that link (cannot find now) were in POUNDS not dollars.

$5k for a 3.2L rebuilt and warranted engine would make my day!

I suspect if you rejected any Box with a few bits of metal and plastic in the filter you'd be a long time looking for something to buy, you'd overlook some good prospects and the car you eventually bought would be no more less likely to spit its IMS bearing. That's my view.

I think from everything I've read, the window between significant debris in the filter but the car seeming to run fine and full blown IMS failure is very small indeed.

[southernstar]

Probably so Pothole, but many people have replaced their IMS bearings and found scoring, even though they had not yet failed. I suspect that at that point some additional metal was showing up in the oil filter. In my most recent oil change (last week), I had two very small metallic particles on the magnetic drain plug and none in the filter.
I will probably put on another 3000 km before I put it away for the winter and then I will change the oil/filter again in the spring before it goes back on the road. Hardly fullproof, but I still believe it is a worthwhile exercize.

You don't drop the pan every time. But neither does every Porsche go 2+ years without an oil change. One of the principal causes for IMS failure is simple oil starvation and or contamination. Once the inspector/mechanic got wind that po was neglecting a vital part of engine preservation/care he should have not hesitated in offering to drop the pan to gauge if there was damage. Any non-mechanic on this forum would tell you 27 months is a red flag, especially if this is a single row car.

I'm curious to know the total number of oil changes this engine actually had. Probably fewer than my trips to the dentist.
