rich71 Posted September 5, 2016 Share Posted September 5, 2016 I hope somebody could help identify these 2 metal fragments i have found in my sump, the engine is a 1.6K wet sump....I have looked at an engine manual for the k series but can't find anything of similar size/shape. The engine runs just fine with no unusual noises, smoke etc so I am hoping that it is from an external source at some time in it's life. They look like it is one piece that was once joined as 2 of the faces match, the long edges are all smooth so i don't think it was ever wider than 5-6mm.https://www.dropbox.com/s/89doe50iegrj4jt/IMG_0502.JPG?dl=0https://www.dropbox.com/s/mjgt30chcwqfqv0/IMG_0504.JPG?dl=0https://www.dropbox.com/s/21o4u97h2ayickf/IMG_0503.JPG?dl=0Thank you to anyone who can help Link to comment Share on other sites More sharing options...
Mort Posted September 5, 2016 Share Posted September 5, 2016 Can't help with the identification, or why they would be in your sump, but they don't look like they've come into contact with anything - which has to be positive - and if something that large had been you'd certainly know about it.

john milner Posted September 5, 2016 Share Posted September 5, 2016 I've never had to work on them so not sure of the size so only familiar with the rough shape but could it be a bearing? It would probably make a racket if it was so hopefully only an outside chance.http://www.seriouslylotus.com/drivetrain/rover-k-series-drivetrain/k-series-standard-type-crankshaft-bearingshttp://www.myfreelander.co.uk/Engine/18k.htm Link to comment Share on other sites More sharing options...
rich71 Posted September 5, 2016 Author Share Posted September 5, 2016 John, that's what i initially thought but they are not wide enough, they are only 6mm and the edges don't look like they have come from something wider. I would also have thought noise would be noticeable but it runs with a nice tone and revs up just fine...i am somewhat concerned but am beginning to think and hopefully it's/they are from something else, although i don't understand how they would have got there unless dropped in from above.

Area Representative Nick Bassett Posted September 5, 2016 Area Representative Share Posted September 5, 2016 Given it is a K series, might be worth contacting Dave 'DVA' Andrews to get his thoughts...? Link to comment Share on other sites More sharing options...

Member Jonathan Kay Posted September 5, 2016 Member Share Posted September 5, 2016 Are they attracted to a magnet?Jonathan Link to comment Share on other sites More sharing options...
rich71 Posted September 5, 2016 Author Share Posted September 5, 2016 Yes they are, although they are not themselves magnets which i thought they might be at one stage.They do look quite old even the ragged ends which means to me as though it's not a recent thing, apart from noise if it were the bearings how would i know?

Mark Durrant Posted September 5, 2016 Share Posted September 5, 2016 If these were the bearings you would have zero oil pressure and probably a rod sticking out of the side of the block. I have dismantled a few K series engines and cannot recall seeing anything resembling the debris. What is the history of the engine, do you know if it has ever been rebuilt?

John Vine Posted September 5, 2016 Share Posted September 5, 2016 How intriguing -- not to say alarming!It's difficult to imagine that they originated from some engine component. Could it be they're part of something ferrous accidentally dropped into the sump while it was off during a rebuild or bottom-end work?. Could the chips along the edges have been caused by contact with a rotating crank as they jiggled about?JV Link to comment Share on other sites More sharing options...
Mark Durrant Posted September 5, 2016 Share Posted September 5, 2016 I doubt they will have got anywhere near the crank on a K wet sump due to the baffle plate and foam. Link to comment Share on other sites More sharing options...
rich71 Posted September 5, 2016 Author Share Posted September 5, 2016 I have had the car a year, to my knowledge and looking through receipts i can't find any evidence of a previous rebuild, but over 20 years who knows. The sump foam was changed in 2014 as was written on the sump so i would have thought it would have been after then or the debris would have been found.

rich71 Posted September 5, 2016 Author Share Posted September 5, 2016 Also if they had come from above, let's say bearing then the baffle and foam would have stopped it above, mind you perhaps it did and by removing these to change the foam that's when it dropped into the sump....it may have been there since a previous rebuild and maybe hidden somewhere, is that possible or am i trying to appease myself?

john milner Posted September 5, 2016 Share Posted September 5, 2016 Ignoring what the fragments look like in order to eliminate the engine, if the foam is in place what lumps of metal are there in the area? The only ones I can think of are the pick-up and the baffle plate.If they are not part of the car could it be the remnants of something used as a third hand to hold things in place while the foam was changed?Failing that I reckon the last person to have the sump off put the metal in there as they were doing two jobs at the time and forgot to remove them when the sump was refitted.

Bio Posted September 5, 2016 Share Posted September 5, 2016 Could these be parts of the oil pick up pipe securing strap? Link to comment Share on other sites More sharing options...
rich71 Posted September 5, 2016 Author Share Posted September 5, 2016 The oil pickup looked all in one piece and certainly bolts back up again Link to comment Share on other sites More sharing options...
revilla Posted September 5, 2016 Share Posted September 5, 2016 I have also rebuilt 3 Ks recently and I'm fairly sure they don't look like anything I took out of, or put into, any of mine. Foreign objects of some kind I reckon. How they got to be in there is the mystery! Link to comment Share on other sites More sharing options...

rich71 Posted September 6, 2016 Author Share Posted September 6, 2016 I had a quick relook at the dipstick and it is somewhat thinner and flexible whereas the parts are not, they are 1.5mm thick or thereabouts....nearly had a solution there i thought Link to comment Share on other sites More sharing options...
revilla Posted September 6, 2016 Share Posted September 6, 2016 A friend sent me this picture of a strangely leaking spring clamp on a coolant hose. The clamp looks to similar kind of metal, similar size, similar curvature. So broken legs of a clamp that was stubborn to remove? Link to comment Share on other sites More sharing options...
Alan Bowler Posted September 6, 2016 Share Posted September 6, 2016 Very strange. Is the sump in good condition, or has it been welded after a few knocks? Could be remains of a previous failed attempt at patching a leak from the inside? Link to comment Share on other sites More sharing options...
rich71 Posted September 6, 2016 Author Share Posted September 6, 2016 it could be...does anyone know dimensions of the bearings to compare, like the ones on the left out of curiosityhttps://www.google.co.uk/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&uact=8&ved=0ahUKEwjKz_yLpPrOAhUBKcAKHdheAGAQjRwIBw&url=http%3A%2F%2Fqedmotorsport.co.uk%2Fqed-shop%2Fview-all-products-in-shop%3Fkeyword1%3Dk%2520series%2520spigot%2520bearing%2520caterham&psig=AFQjCNGij9Tm9SsAnzMcqMrDnvZ0_m2d4w&ust=1473235470480523The other thing i thought of while looking through the overhaul manual to help identify is the flywheel locking tool referenced in the document below (18G 1674), i can't find any actual images of one onlinehttp://www.vgkracing.com/k%20engine%20EU3.pdf Link to comment Share on other sites More sharing options...
SM25T Posted September 6, 2016 Share Posted September 6, 2016 It is possible to find gravel in the sump when you remove it. It gets lodged on a little shelf on the outside at the rear ..... As you remove the sump it falls inside .... causing great concern. Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted September 6, 2016 Member Share Posted September 6, 2016 Was there a "friend" around between removing the sump and spotting the bits?Jonathan Link to comment Share on other sites More sharing options...
