Clutch noise. Video added
Turbo Mini Forums

I have just started my new turbo engine for the first time. Everything is new and untested. Ive got it idling at 1800rpm to break in the cam, but i am concerned there is a lot of noise coming from the clutch area. Its got an RTS clutch, straight cut drops. There is a constant clattering noise which totally vanishes if i dip the clutch. The revs dont drop when i do this so theres a good thing at least. It aint the same noise you can get if you have your idle speed set too low and the drops rattle, this is louder and its there all the time
Another problem which could be connected is noise from the starter motor. Its a new Brise starter and when the engine catches the starter does not seem to disengage correctly

Help please

Sounds like there's nowt wrong.

SC drops make a right rattle at idle unless you dip the clutch; it's normal.

Ive not let the revs drop below 1500rpm yet, the noise is constant, not really the random rattling you get from drops?

Does it go away when you your clutch in?

Can you get a video clip uploaded?

Goes quiet if I press the clutchpedal.

If you press the clutch the drops will stop spinning
They really do make a racket

A video or sound clip is best though just incase there is a problem

As the gents say above its a classic, especially. If the oil is hot and its hot weather like now.

Turn the idle up, 2500 to knock the cam in!

I recall Simon (madmk1's) car sounded terrible when he tried one of those A&R Precision aluminium flywheels.

Are you running one of those by any chance?

If something is worth doing, it's worth doing half of.

The flywheel is steel from MED. The noise is better described as the noise you get from an alternator with knackered bearings. I'm hoping it is the clutch release bearing.

I think that's what Si's sounded like.

Have a look in his build thread.

Put a video up, however I think your panicking for nothing, sounds like typical rattly drops, mine were horrifically loud to the point they hurt your ears.

....and on the flip side my MED floating drops are silent at idle....no rhyme or reason to these things sometime

Hope this video works. After i rev the bitch i dip the clutch a couple of times and the noise disappears with the clutch down

sounds very tinny...a bitmore like a clutch component than the drops...you usually get a very solid sounding clacking from them......hard to tell just from a video though.....

Anybody else think something is wrong after listening to the video? Its my first experience of straight cut drops, some more thoughts on this would be a great help

Guys now ive put the video up any chance a few more of you could listen and tell whether the noise is normal or not. Ive got to pull the engine back out if the noise is wrong. Cheers

Drops, sound just like mine did.

Almost. Only thing stopping me driving it is lack of mot and worried that the noise is something serious

Doesn't sound serious to me mate.
