Dan you are lucky Trevor has an extra engine. I hope it performs as well as your original. Trevor this is not meant as an insult. I found when I got my new engine that while it was good it was not quite as good as the older one. Of course that's the least of Dans worries!

Waylander - I'll have to defer to Trevor to respond to that question , but if I understood him , and our other friend who is a very knowledgeable mechanic ( who came by to help yesterday ) correctly, I believe that's what they also suspected happened ..

The oil pick up tube seemed to be solid, although who knows if it does not have a small crack somewhere and causing oil starvation .


RAP, - the other engine can't be any worse , now can it...? LOL I do want to use my cams since that entire thing looks out of the box new ..not even the slightest wear on the teeth, the pads ( well the top pad ) does not even have a trace on it, and the color is again as if it was just replaced yesterday , yada yada..


Vlieg---- I think the filter issue deserves it's own thread , I was horrified when I saw how mangled and partially disintegrated that insert was . I actually thought it was those metal pieces ( from the filter ) which were sucked into the engine and caused the catastrophic damage, but Falsh said that"s not at all possible. Oh, and there is no way anyone can install that incorrectly, it's just a simple drop into the case thing.. As you mentioned it was not just one isolated occurrence , so it's pretty evident that the inserts are poorly made , only the exterior case seems to be bullet proof ..


Well , crappy and costly news but whatchagonnado ?! Sheesh, and I thought these engines were supposedly bullet-proof. So much for that theory ..

You are very lucky to have Trevor to help you out. What a stand up guy. This is what makes the 968 community so damn good!

I would suspect that oil filter insert caused some oil starvation issues, should be signs of it when you dig in. Wasn't there a revised canton that came out, or was that just the housing?

 

Also when you say mangled, like crushed? Maybe a failure in the housing that caused an over pressurization crushing the filter? The only thing I can think of that would cause an insert to deform like you describe if it went in non deformed, other then the materials totally breaking down.

if you can get the idea.

 

I do, but I don't want to see pictures of the damage.

 

sounds really catastrophic

Same  thoughts here  i do not think the metall parts of the filter would wash into the engine , the rest of the filter material however might , but restricted flow because of the mangeld  filter is a possibility .

what filter is this?

 

and what's wrong with the genuine one with a need to change it to a different design?

Nothing wrong with the Original filter ,exept it wil leak all over the engine  when you change it for a new one ,

[flash]

the canton filters a lot better than the stock unit (about twice as well)

 

it is important that you put the cartridge on the lid, and then insert it into the can, and that you do not over-tighten it, but other than that, it's a no brainer, and a superior filter.

Thanks checked out the website


With the reports of mangled and flattened inserts, are they getting restrictive at 8 microns and getting sucked flat?


I agree changing the filter normally is a real messy job


Just wondering that's all

Dan, I just ordered some Blackstone kits so that we can send your engine oil off for analysis.  Depending on the metal they find, we could understand if the failure was only a ring or also involved the bearings / oil starvation.  I don't think there was an oiling failure here - also, I believe you would've seen a low oil pressure alert on the dash.  I suspect that the engine had a bad ring for a while given your high oil consumption and it finally broke.  I also want to send oil from the backup engine for analysis so that we can have more data / confidence that it's in good condition.

That's awesome !  I cant thank you enough for everything , past help, and pending help , LOL..

 

And yeah- what Jay said !!!

Could the oil pressure relief valve be stuck closed? The pressure could have gotten too high for the oil filter insert, mangeled it and in it's turn caused a blockage. Oil starvation would be the next thing in line...

I will sell you mine half the price with i think 6inserts and shipping from the Netherlands

I will not let i near my 968 ever again .

BTW, this is a photo of the segment of the ring found at the bottom of the oil pan ..   it's slightly over a cm , 12mm to be exact.. ( just so the photo does not fool anyone about how large it may appear )   - and you can see the slight curve .   So if I understood how things work, the ring breaking causes the piston to seize / fuse inside the cylinder and therefore there is no way the engine can be cranked,  right ?

Also weird that for several minutes ( five, maybe ten minutes ) after I started to hear the rattle ..which I now assume was the piston with a broken ring ? .. the car was still capable of being driven , albeit losing power very quickly.  I suppose it takes a while for the pistons to seize...

wish I would have taken a photo of the old filter insert also in its' " mangled " form, before we took it apart to see check everything inside its outer shell ..but basically the bottom ring was broken off, and the top edges which were attached to that ring were were disintegrated ; about 2 mm 's worth.  that part also looked smashed in .  the rest of the insert , about 90% of it was appeared ok..just ok...

How strange, Canton filters have always had such a great reputation among racers. I have been running one on my 968 for a while with no issues what so ever.

 

That looks like part of a 3 piece oil ring, which usually gets spit out when the cylinder taper gets very high and blow-by forces it out at high RPM. I still want to know why the motor is seized; that piece of ring is only part of the picture.

I take it your not convinced by the claims then, personally I will put up with the mess by removing the tray underneath and washing it down with brake cleaner afterwards.
