thanks for the feed back ..
Gulp.. what is it? .. Now I am more paranoid !
its too thin for any sort of lock wire (apologies for the photo, will try and get some better ones tonight)
Looking at the oil pan I used, this strand and another, where the only 2 that came through. The rest (smaller bits) where on the sump plug..
On a happier thought the contents of the drain pan doesn’t have a sparkle So I guess there are no chrome flakes left over in it (like tinsel flakes)
Well this is one for the book?. But I don’t like the thought of that material flowing around the engine.
More news as it comes in……
