Gentrix 2 1 Cars Posted May 20, 2006 yesterday I took a closer look at my bigendbearings and the Oilpump, because the oilpressure was too low. this is what I found, mainly in the Oilpumppickup. (the pump got a new piston and Spring - will see how that works) http://www.french-classics.de/Upload/album...oilsumpcrap.jpg I have absolutly no clue, where this spring-thing is coming from - any suggestions? Where have been a few more of this Metalflakes, but these are the biggest. I guess they are from the bigend bearings - eventhough the bearings didn´t look too bad - they are worn, no question, but not down to the copperlayer. Something I´m worried about is that one of the Rods seems to sit more tight in the piston, than the others. I had to push the rod&piston upwards, to get the Rod beneath the crank, so I could refit the upper bearing. And to move the one Rod to the side was heavier, than on the others. Could it be, that the upper smallendbearing on this Piston is out? thanks andi Share this post Link to post Share on other sites

Emmy Seize 8 Posted May 20, 2006 They look like remains of valve stem seals to me. Yes, I agree on the spring-thing. I doubt that the metal flakes come from the big-end bearings, though. Any headwork done to the engine ? The fact that you found remains of a valve stem seal near the oil pickup suggests that there was either a lack of cleanliness at the time of the engine build or that the problem really originates from the cylinderhead- area. I find it hard to imagine how the little spring can find its way into the sump without anything being wrong. Share this post Link to post Share on other sites
Gentry_Ba 1 Posted May 20, 2006 Hi Andi! I think it's a spring from on of the valve-seals, too... I didn't know, that you a registered here, too? Puuh, sorry for my bad english.... Cheers, Matthias Share this post Link to post Share on other sites
Veero 1 Posted May 20, 2006 How can it be a valve stem seal spring? The spring is intact (as in a complete ring) so surely it would have to have escaped from within the confines of the valve spring, and tappet to get into the oil system? It definately looks like a seal spring of somekind but what seal is fitted to the engine that doesnt have a shaft or rod through it taht would allow it to come out intact if you see what Im saying... Still not good tho Veero Share this post Link to post Share on other sites

jack biscuit 0 Posted May 20, 2006 (edited) hmmm.. not nice! Perhaps the spring was pulled off whilst removing the valve stem seal, roughly.. stuck to the side of the oil gallery for a bit then flushed to the sump later.. raises the odd question or two. Not a lot of washing eh? Edited May 20, 2006 by jack biscuit Share this post Link to post Share on other sites
Gentrix 2 1 Cars Posted May 21, 2006 Hi Andi! I didn't know, that you a registered here, too? Hi Matthias, the web is a small place - and only a click away. And the 205 drivers community seems to grow every day. There was a thread, the day before, from a guy from the netherlands(I think) who visited someone in UK and he met almost 3 Drivers from this Board on his way, coincidentally. see you on *Advert* Andi Share this post Link to post Share on other sites

Not a lot of washing eh? @ Jack I guess you are right here. Sound like a possible procedure, that it happends during a valve-stem seal change. Washing: I will take some pictures of the bearings, next time. The stem-seals seem to be in shape, because the motor has no sign of blue smoke from the exhaust, and oil consumption is very low. But the metalflakes make me worry. 1. I had no headwork done - at least nothing I know about - exept a assumed headskim after a Headgasket failure, that the former owner mentioned. But this stuff looks like Alloy and isn´t magnetic while it is only little thicker than alloy-foil. Could this material come frome the tappets? I really am tempted to rip the head off an bin the low compression DFZ head at the same time But that is a lot more, than I was willing to do to this engine, as I want to reassemble my Mi over the next year. thanks to all so far andi Share this post Link to post Share on other sites
rescue dude 0 Posted May 22, 2006 The metal flakes are the wrong colour to be bearing material. I agree with the others that the spring has been left in the engine when it was re-built. As an engine builder myself i'm shocked by this!!!!!! I'd be tempted to give it a good clean put it back together Flush the oil system and see what happens. I'll keep an eye on this thread cos i really would like to know the result of this one. Share this post Link to post Share on other sites
