engine damage finally repaired

[AshleyPark]

You might have screw loose, in the head maybe?

[Craven]

? Front engine pulley loose, do you have the fan belt fitted ie are there any ancillaries rotating.

[checkrail]

I have been advised that the QED front covers often have clearance problems with the chain rotating..
Another stripdown!

Buy or borrow a cheap borescope and investigate down the cover where the chain may be hitting before pulling it all apart again

A Mechanics Stethoscope can also be handy for locating a source of noise. They're just a few quid on Ebay.

While I agree a stethoscope would be handy you have only to turn the crank a fraction to get the noise, the chain must be touching somewhere around the bottom of the casing. It's a very echoey sound.

A bit of a long shot but can the dipstick tube (and/or dipstick) foul the chain if the tube has been pressed in too far?

[rgh0]

Yes if the dip stick is bent or the tube at the wrong angle it can hit the chain, been there done that have and have grove on the dipstick to prove it.

In my case the dip stick was bent by the hole in the windage tray being a little to small

Try twisting the dip stick 180 degrees or removing it to see if the noise goes away

Good call Rohan. There is of course the possibility that something has been unwittingly dropped down the front of the engine during assembly John? I wish I was nearer....

At last the noise has been sorted, it was a chipped tooth on the crankshaft sproket.
Just don't mention woodruf keys, replacing or the cost!

When I posted my last reply saying the problem was sorted and the clatter was gone I had yet to replace the sump, so that I could make sure everything was ok as I turned the crank.
I refitted the sump, added some oil and lowered the car level, rotated the crank and the clatter is back.
So what on earth is going on?

Once again please help Thanks John

1300 sump??? ...Big end cap catching.....which side is the oil drain plug on? Right side on a 1500 and Left side on a 1300 as I recall.

[checkrail]

Thanks for the reply, the plug is on the RH side, looks like the sump will have to come off again but why would it now be catchng?

John
For clarity the engine is in the car and you only removed the sump ?
Turning the engine in this condition there was no noise.?
This points to the sump as stated by 26/36.
You can now look for marks left by contact or even mark up moving items with tip-ex and try fitting sump temporarily and investigate from there. Is the drain plug on the right looking from the front?
Was the noise continuesly for full rotation or short periods. Or even blocked at some point.
