Went out for a drive today (not a hard drive) and when i pulled up in a car park there was smoke coming from the front of the car I looked around and could not see where the hell it was coming from The engine felt pritty hot and the exhaust shield was so hot that when i spit on it it sizzles away pritty quick. It was raining and seemed that the rain has splashed on the front of the engine and was evaporating cause it to smoke The water temp inside the car is perfect (half way).
Any ideas as am a bit confused

also when i turn the engine off, at the back of the engine near bulkhead it seems to give off a little fart!! (best way i can discribe it)

Nope sounds ok m8 nothing unusual

Your manifold and the turbo exhaust housing can hit 900C on a spirited drive, that's why the heat shield is there in the first place, it's to protect your aluminium bonnet from the turbo.

Handy temper colour chart thingy so you know how stupidly hot your engine bay is (clicky)

I've had mine between light red and orange before

Even on a slow drive the exhaust gas is around 900-1000C and the manifold will be a good couple of hundred C, enough to boil water falling on it from the bonnet vents. Unless you can see a leak or the coolant temp gauge is reading high it's nothing to worry about. Just remember to let things cool off before turning the engine off if you can see an orange glow through the intercooler

The fart noise I have no idea about, it could be a pressure release from one of the pressurised systems in the car (brakes, steering, intake, ac turning off or something else) and may be entirely benign. Other than that vague explanation I have no idea though

know what you mean by the heat. Have found a pipe that has come off the plenum (right side as you look at it. Could this have caused it to run lean thus the reason for engine heat?
The car was making some deep popping noises before i put this back on.

I need to buy a good internal combustion engine design and theory book. If something popped off that definitely caused it to run lean then theres a good chance the popping noise was det, and that isn't good for the pistons or the block (or so I've heard). Other than that I wouldn't want to diagnose anything because I'm in unfamiliar territory with the throttle end of the engine, my knowledge is limited to the basics I'm afraid (ie what pistons are, not anything to do with valve shaping for enhanced laminar flow and all that stuff).

Someone else here can hopefully let you know what the damage might be
