Hi would any one have any suggestions why a squealing noise comes from the front of my engine like a loose belt but with no belts connected it happens once the engine has warmed sometimes it goes away and other times its worse than others

I'd be cautious of a sintered bronze (or similar) bearing not getting enough lubrication, or with insufficient clearance (as it warms up). Perhaps a cam journal bearing? They can make a horrible squeal as they die
I don't know your engine though. I hope it's something much more benign, but if it's a fresh motor then a bearing clearance issue should be checked and (hopefully) discounted

Its not an air leak we have checked all that its coming from behind the front cover down low to the left hand side below the alternator , the engine was rebuilt several years back but only about 7000kms ago and been ok up until now , sometimes after its had a bit of a thrashing for want of a kinder word it stops might have to pull the front cover off for a look

Isn't the dizzy on the front of these motors. Check that for wear. Best way to find a noise is ti get a steel rod and put that on different areas of the motor and put your ear on the other end. Move it around until you find where the noise is coming from.

My old car did this, loose exhaust manifold bolts, it was letting exhaust gasses out and the gasket would squeel
