Sparkling oil, time for IMS Replacement ?

bazhart said:
All good advice but one question unanswered (unless I missed it?) what colour were the shinny non-metallic particles. If they were bronze, copper (not magnetic) or glittery it can also mean crankshaft bearing wear. If the mileage is over 80K I would monitor the particle release again soon (yes cut open the filter) and make sure they are just silver.

Now guys - please don't start having a go because this would be bad news - it's not my fault and the question has been asked and this is a real possibility and frankly - if they are from a crank bearing it will be cheaper to try and fix it before the crank is damaged than afterwards.

I really hope this is not the cause and that by checking the colour you can be reassured about it.

Good luck,


Baz

At the time they were gold. But they didn't settle on the oil drainer so I couldn't see properly.
Today at work, had another look at the filter and the magnet e I found that they are silver but really really tiny, like sand
Been silver and magnetic, I would say they are from IMS
I have already booked to replace the IMS bearing and I'll still keep the eye on it

What bearing you going for ? Original or aftermarket ?

Aftermarket. It is at least what all independent specialists recommended me

What you guys think?

Think if I were replacing id also consider aftermarket.
Wouldn't consider the LN solution from what I've heard of late.

I've heard about a cylindrical type bearing from eps that looks interesting.
What have you been recommended?
 
I can't comment on what solution is best but I chose the roller bearing type.

So far it's survived 1100 miles :floor:

I'll let you know in a few years if it was good or not.

To be honest depending on the car I'd be less worried about the ims exploding than I would be about the crank bearing destroying itself!!!

I tend to agree, if an IMSB goes your engine will require a full rebuild and need quite a few differing parts, if your crank bearings go you will still need to do a full rebuild but it's getting hold of a used crankshaft that could actually stop the rebuild going ahead at all and a new crankshaft is over £3k just for that single part, it is worth looking after that crankshaft and is worth doing a preemptive rebuild just to keep the CS in good order.
 
As I'd said depends upon the car. Mine is an early 3.4, dual row ims and seemingly far less likely for bore score etc etc. That said I do believe that any 'high power naturally aspirated' engine will lunch something internally at some point. The weakness tends to be the crank from statistics and as stated they are seem like they are made of unobtainium these days!
I think there is a market for preemptive rebuilds. If, at a reasonable cost, you refresh the engine and save things like the crank it's got to be worth it. I come from motorbikes where rebuilds are a yearly occurrence!!

I agree with you, with crankshaft the IMSB should be the least of my problems.

What years are more prone for bore scoring?
I thought the early 3.4 and the late 3.6 were more prone for that
 
I think the early ones did the d chunking although those that were seem to have if you get my drift. The 3.6 been a bigger bore seems more prone to scoring. I've done the low temp stat thing, bigger sump etc. There's only so much you can do to prevent problems and only so much worrying you can do!?! If it goes kablamo it happens!!
