Advice On Magnetic Sump Bung Swarf
Hi All,
Did an oil & filter change on the Scooby yesterday & there seemed to be a lot of material on the magnetic sump bung. The car has been stood all winter & it's a bit of a worry to see this. There were no big bits & between my fingers it just went into a fine paste, but is this normal. I change the oil evry 3K & normally only see minimal particles on the bung.
Thanks, Richard.

The oil was trained in to an oil drained with other oils so I don't have it. I don't think it's right either but it can't be shells as they aren't magnetic. Possible cam material, like I said it felt like a fine poste but quite worried now.

Has the engine been rebuilt recently Richard ?
If so, you would expect to get very very small particles from the rings bedding into the bores but I wouldnt expect that amount of swarf from a normal routine oil change.
Unusual to have the hardening on the cams/valvetrain wear and without an increase in top end noise.
Try cutting the old oil filter open to see whats trapped in there.

Not a full rebuild but HG replacement with shells & hone last year & as I hardly use the car , this is the first oil change since. Could this be the cause of the material on the bung?

Hopefully, It'll clear but it really shouldn't have been there in the first place. As suggested, if you've still got the filter (unlikely?) cut open the side to reveal the 'in' side of the filter media and see how much crap has been caught. The filter should protect the bearings from the stuff although it has still gone through the pump on it's way to the filter.
Personally, I would add a can of Wynns, Comma etc flush to the existing oil, run the engine for 20 min or drive gently for a few miles, drain the sump and re-new filter. Fill with a cheapish oil and run with this gently for a few days (to flush any remaining old oil with the Wynns stuff in) then change oil and filter again for some good stuff. Sounds a bit of a pain (on the wallet as well!) but that should clean the internals. Don't be tempted to use a sump full of 'flushing oil' The wynns thing is a better alternative.
I've used the above procedure with no problem. (I'm expecting some will shout 'NO' to the use of it!
)
There was a thread on here not so long ago discussing the virtues of magnetic sump plugs and some were quite adamant that they were a waste of time and generally berated those who fitted them. In your case the thing has stopped some undesirable s**t from going where it shouldn't, so it's been a good thing! On the other hand, like too many gauges and knock sensors etc., it can make you paranoid!

I'll do as suggested to flush any remaining contaminants out. I'll cut open the filter too, but I don't think it was too clogged as my oil pressure has always been good showing 2bar when fully warm on tickover & as much as 6bar when cold.

The thing is the oil that came out looked normal so without the magnetic bung I'd be none the wiser. Oil pressure is normal & no unusual engine noise. I don't want this crap going round my engine so I'll be using cheap oil & filters running it for a couple of miles then changing it again until it's totally clean, I'll then switch back to Fuchs & gen filters.
