soooo, just did an oil change and have a "not insignificant" amount of filings in the oil... car is on 04 gu3 zd30 (alloy top version).
anyone had anything similar recently? I'm assuming a whole world of hurt is around the corner, so what are my options?
way i figure it:
1) let it blow up and part it out
2) get a crate motor
3) get a second hand from somewhere
4) get a properly recon'd second hand
5) get this stripped and recon'd
6) is there a 6?????
anyone got an idea of costs etc??
cheers
Are the filings steel of allow? Usa a magnet. What does it sound like?. It might (but probably isin't) somthing repairable. How many K? What's the rest of the car like?
Any strange noises ?
You could try changing the oil, and re-checking after another 1000 Klms, just in case ...
the filings are very small, looks to be metal, thinking bearing has gone?? No real noises in the engine, does have a little shudder at times i've noticed recently but it's very slight at best. 255*** on it, rest of car is ok, has some of the usual dints and dings and issues for it's age, but otherwise fairly normal... I just did a run from brisbane up to central queensland and back on a camping trip with 7 on board and towing a 2t camper - bloody thing never missed a beat... only discovered it during an oil change.
i find a magnet and triple check - but almost certain it's metal. The filter was full of it and the oil was all nice and sparkly with filings when we dropped it out...
Magnet test if magnetic=steel=maybe a bearing going. If not magnetic=alloy=oh $*^t.Quote:

nah mate no oil gauge... but been playing with a couple of fridge magnets, not getting any joy so might be alloy after all... the pieces are so small and fine i can't even look at them properly... trying to find a kids magnifying glass lolQuote:

It can be a left over from some oil additive as well.
Either way, caution is the way to go.
Better to filter some of the stuff with a strainer with a cloth.
Clean it with petrol and have a close look with a magnifying glass.
Also feel the stuff between fingers after cleaning.
Yeah, a CSI approach is the way to go. :D
how long since last oil change and oil filter change . what brand of oil and what weight eg; 10w-40 . just wondering if to light or poor quality a oil might have been used .
Personally I would put a few more km's on this oil then drop it and send it away for analysis. It's fairly cheap. You'll get change from $50
Hastings deering should do it, most oil co-ops should be able to do it.
Its like a blood test for your engine and a very good preventitive maintenance tool. The analysis will tell you what the filings are and where they came from
That isn't sounding real good, and the worry is that if something fails it will be instantly catastrophic .... murphys law will have it fail when you are furthest from home to cost you more too....Quote:

Ironically, my GQ always broke down either at home or just down the road, & still managed to drive it home by patching it up.Quote:

The fact is that the OP's gota confirm the stuff he found in oil are indeed metal scrapings. It is confirmed it's not steel so far.
What are the chances it can be an alloy?
This is the only chance I can think of.
The head was machined while ago and put back on without cleaning it properly.
That's the only scenario I can think of for the origin of those metal dust.
But, he's gota confirm it's metal first.
Hasting Deering would do it for around $50?Quote:

Yeah sadly it does not look good at all.
I take it you have serviced the Patrol every 5000K
you can run a bit over or at least change the filter.
With 255K on the clock you might expect something to fail
Yeah, I would go to panic mode if I found metal dust in the oil of my car.
Since you're certain it's metal, I wouldn't wait.
I dunno enough about diesel engine bottom ends to speculate where the alloy metal scrapings would come from.
May be a diesel guru here can post an opinion on that.
Apparently there are bimetal and trimetal bearings in engine cranks.
So, it's a good thing the engine is still running but will be a bad idea to keep running it if the metal scrapings are
from those bimetal bearings.
Better to drain all the oil and change the oil and the filter while examining the metal dust in the old oil.
If it's not a left over from an old head job, then it's not good news.
I would have the old oil and the metal dust analyzed straightaway.
Putting if off can end up costing real big money.
Diesel engine bottom end rebuilding is prohibitively expensive, most of the time you are better off buying a used engine.
yeah serviced regularly etc etc and all up to date... i've had it 6 yrs and haven't done the head etc so can't be remnants of that - especially given the quantity of it.
so then given we seem to agree i'm fairly screwed lol - back to my original question...
who's done the rebuild/replace with 2nd hand/crate/upgrade etc etc??? anything to be aware of? is one option better than another??? any recommendations for any options especially around nthside brisbane?
my mechanic can install a new motor etc obviously, but anyone got any ideas on where best to get a motor from? he's checking his contacts, but he's a close mate so we spoke about posting here etc to see if you mob had better (more cost effective?) options...I don't need to drive the car so apart from moving it from it's present location further into the yard (20feet) I can leave it alone until we have a scenario that works.
cheers for the discussion thus far lads!
Fleabay has these rebuild kits listed.
If you can do the job yourself, it's a big saving.

Also check Bumtree. There're quite a few people sell their stuff there as well.
BTW, it's lot easier to replace the whole engine than rebuilding the old one, labour wise. All you need is an engine crane from super cheap or a hire one.
Advantage of rebuilding is that you have peace of mind for years to come. Considering you're not desperate to have the vehicle running straightaway, I would rebuild, provided you can keep the cost to a minimum. Otherwise, engine replacement is the easy and quick solution.
