*Issue resolved* Who wants to play, guess that clanking sound! (Video inside)

[Tanktheory]

edit; video doesn't seem to appear for me, here is the link http://www.youtube.com/watch?v=61lMfnO3EmA

So this is where I'm at. I'm stumped. Sounds like rod knock to me, but I'm hoping someone here can shed some light. I'm hoping it's just xyz which is just a quick fix..

Thanks guys

Update! 10/20

So I finally had time to work on the car, not one of you would have guessed the cause of the clunking..



Crank pulley. 1 bolt was completely sheared off, the others maybe had another 10 miles in them before they wore completely off too.

So there we have it. Problem solved!

First get a spark plug wrench and make sure your spark plugs are nice and toit!

Then remove your valve cover and check for things like broken rockers or mis-adjusted valves or some foreign object floatin around.

you need to adjust the valves. or broken rocker.

also i think your oil drip tube is missing....

ya you need to fix that asap.

You may have a needle shard in the lower part of the machine (by the bobbin case or feed dogs), or lint or a piece of thread down there, or the machine may be dry and in need of lubrication, or you may have knocked the machine out of time.

If you work through the steps of what I call a "10 minute tuneup" -- be sure to take the needleplate off and the bobbin case out and vacuum the machine to get all the needle shards and lint and yuck out. Make a special point of cleaning around the feed dogs, too. Also look carefully at the sewing hook to make sure it's not all nicked up. Reassemble carefully and rethread, using a new size 12/80 needle so you can check the timing against the timing diagrams at: http://sewusa.com/Sewing_Machine_Repair/… -- I doubt it's a major issue with the timing, as the machine is still stitching ok.

While that sound could be a rod, there is no way to tell from the video. Adjust the valves and if that doesn't help, use an automotive stethoscope to find out if the noise is from the top or bottom of the engine.

Have you recently changed the timing belt or water pump? I forgot to properly torque a tensioner bolt and had a weird noise. The $8 automotive stethoscopes are wonderful tools.

[Cabriolet]

srsly read what i posted. missing that drip tube is very bad.

[5Toes]

You mean the oil spray bar?

[dougie30]

this is what my car sounded like before i skipped timing and my engine blew up... id fix this asap

[Tanktheory]

I checked for a needle in the lower part.

Thanks everyone for the replies. I am missing the oil spray tube, just noticed that thanks to your posts. thr PO did a head gasket and timing belt so its possible he forgot to attach the piece. Anyone had a part number on that? Can't get the oem site on my phone.

Checked the rockers nothing broken, going to check valve clearances next. Hopefully its not gonna jasplode :(

My mind is exploding inside...

Best to find a junked car/engine.

AND make sure you check those spark plugs!!!

[Tanktheory]

Checked the spark plugs, they are nice and tight. I'm gonna buy a stethoscope tomorrow as well. I wasnt able to check the valve clearances because the engine was hot, I'll check those tomorrow as well.

My last E30, the clearances were way out of whack and it made more of a ticking noise than a clunking noise.

Thanks for the diagram Paper, I guess I'm gonna have to find someone reliable on here to source that part for me.

[5Toes]

anything new?

Youve clearly never driven an m20 car. They sound like sewing machines. I learned to love the way mine sounds when the valves are properly adjusted.
