rounded lug nut, and engine noise.

timing belt has teeth so a) it doesn't slip unless its fucked and b) at that point your car stops working full stop.
Much more likely to be a loose fan belt or alternator belt. but then again i doubt its a belt cos it would do it when you fired it up and stop after a bit.

Take it to an exhaust place and ask them if they think its an exhaust leak

thanks for the replies fellas.

he is a bit of a dick! he has destroyed pretty much every car he has own.

-Eg Si wrote off, driving by himself on L's! ...dick
-his sisters Eg banged up ever panel! ..again dick
..i saved the ae86...which he pervious owned....
he bought it with moderate rust for 3400, i bought it stripped down off
him in poorish state for 600.

so besides that he is ok. haha

as for the sound from the motor, it isn't any belts as i have checked and tightened them.
the noise is a high pitched whistle....and it is coming from the motor.
and i am not sure...but think it is been amplified through the oil breather.
the noise only starts about 5mins after start up, when driving and the engine is warmest.

hope that desciption helps.

and as for the nuts i will have a go at them this weekend.
