hi guys, im in a shit now so i write here because i could use this forum always , when i had any problems.
this problem is a dont know for sure problem. So i dont accept from you guys to tell me what is this, but if you have some thing to say , please do so....

anyway i was about to do the oilpan remove and tighten those loosy screws.
But before that i was on the higway and i was going on a veryvery uphill around 180km/h(over100miles) the gas pedal was on the floor and i was kind of killing it, i guess:(  mr M42 didnt like it. it did like a miss fire on one cillinder and then i felt the engine was weak, so i turned of the engine. i stoped. no oil leak no oil guage light on, no hot cooling system.... all looked good, so i turnt the key and it did start up, but it was like a flat battery problem because when the starter rolled the engine it went hard but affter a few roll it started up, my battery is new so its totaly ok, so it was feel like the engine is stucked a bit you know like when way to hot and then  its just stucks.
affter the start up i heard a noise like a crush crush chrus,(very sad, bad soud)  
affter this i had about 40km to get home.
i started to get home like that, and affter a few miles all the noise went away, but the power was less then before.

befor this day a i had a problem like this , just a bit more moderated.
i was going crazzy and the tick tick nois got loud, then it went away. i just sad this because it might related to the today problem.

so i got home from the highway and remowed my oilpan.
all the screw was tight but i found stuff in the oilpan, i made some pictures so it will be easyer to think about it.

3 things i found in the oil pan.
1- a piece, one side of it is like a black hard plastic(kind of) the other side of it is some kind of metal
2- some kind of plastic peaces
3- metal dust, or minced metal

i cleand up in the pan and around as much as i could, and the car is start up good as it before but it has a bit more engine sound, nothing like what's makes you think bad because those loud bad kicking noises went away, but what i mean is tha engine is louder then it was before this problem.
here are the pictures

sorry for my english.......
please write if you know where is this piece came from and every idea i welcome VERY MUCH
THANKS THANKS THANKS

...looks like chain tensioner rails.  I will send you a link.

item 6 and 14 for starters

[shutter]

I thought it sounded like the timing case as well, but I'm too newb to pick out the parts exactly.  Sheepdog is the master of a torn up case, for better or worse.

[oskard]

Looks to me like a part of your timingchaintensioner, but I could be wrong.

[billb]

You need to tear down the front of the engine NOW (DO NOT RUN THE ENGINE AGAIN).  You will need new timing chain, sprockets, tensioners, idler pulley, seals, and perhaps a timing case.  The first noises you heard were probably the tensioner rail going bad.  Anything after that is bad news.  Might as well do the water pump and thermostat as well, since you'll be right there.  It cost me $350 in parts to do it all 2 years ago.

[romkasponka]

you are lucky pepe m42

[D. Clay]

How does that stuff make it to the oil pan? There doesn't seem to be a big enough hole anywhere.

[pepe m42]

thanks for your ideas, my guess was the chain rail as well, but why would it break??
!!!BMW changed it 1year ago (was expensive) i took it to the bmw because i was in other country far from my garage and had no tools.......
now im in other country again, but i have tools now, so i fortunately can deal with things....

realoem is good stuff im using it too, thanks for the link it was a straight point!

so is it possible that my chain jumped without having problem with valves knock on top of the pistons?

and do you guys think that lots of minced metal is from the timing stuffs?

thanks for the hint to change the thermostat and watter pump, but i just did about a mount ago.

if the rail is broken, then its possible that this why i dont have the same respond when i step on the gass?

anyway thanks for everything! This forum is good and helpful !!! all of you !!!


please write anything you think!
thanks!

[romkasponka]

it could be from old tensioner.

But better check evrything.

look im a do it yourself person but i never opened up the engine so i havent done much job inside the engine.
i changed watter/fuel pump, C.arm bushes, rear weel bearing change, break replace, oil change, the battery behind the guages change, had watter inside problems....... so i usually do what's next, you know.... i guess now is the timing chain rail and who knows what else is the next:D
 
 
anyway thanks, because i didnt know how it could fall down to the pan, but now i do.

...and thanks for the responds!!!

[denious]

wow from all these threads about timing chains and things going bad I'm afraid of even starting my car now!!

[bmwman91]

Be afraid, be very afraid!

BAM!




Yeah, timing case rebuild time.  I am not sure if it would have slipped a tooth though...when I had my timing off by 1 tooth I had pistons hitting valves and it sounded like the diesel from hell!  Good luck!

A word of advice:

Check your cam timing and raalign if necessary then do a compression test to make sure you have no signs of bent valves. If you have bent valves, it might be more cost effective to buy a used motor to put in instead.

i found other piece like the one i found in the pan, but this one was stucked so it couldn't fall down to the pan.


Can you tell me how to align the the cam timing, sorry im not an expert but an explanation or a good link will be ok i think.
thanks for that, and i will do the compression test, good idea thanks.

still dont know why did it happened, bmw changed all the stuff chain tensioner sprockets rails everything....

yes one more, when i put the chain rail, befor tightening it, what is the proper adjusting of the space between the chain and the rail. i hope it make sence for you guys. i was reading the e30 rpair manual on the net and it say adjust space between the chain and rail and then tighten the rail...

thanks!!!
