strong fuel odour. help?

[iwishmyVNwouldstart]

any help on these would be hugly appreciated. i really dont want to have fork out for a trip to the mechanics at the moment.
1/ theres a strong fuel odour coming from underneath the drivers door, i cant see any leaks around the lines, all the hoses seem in good repiar. there isnt realy a smell from the exhaust or the engine bay. the O2 sensor is pretty new. the exhaust smell is pretty foul too. code 34 was showing up, but i tested the MAP with a multimeter and all the correct values seemed to be coming out city driving fuel economy about the same, freeway fuel economy has gone down the shitter.
2/ loud whirring noise from front L/H wheel, pretty sure its the bearings, but the hub seems secure, the noise starts at speeds over 80ks
3/loud metalic clicking noise from the heads down towards the rear of the engine, not the front, it goes away after the engines been running a while, or if you pump the accelorator quickly.

once again any help on any of these problems would extremly helpful.
cheers

I would be looking underneath my driver's side back wheel arch where your filler pipe to your fuel tank is. You should notice a heap of breather hoses there. I say these are your culprits. Now to do them properly you need to take the fuel tank out. Or to get yourself out of trouble for now, just get an inline joiner (probably need two) and cut the broken sections and join up a good piece of fuel line up. But after time the hose will break again further down the line.
Open your bonnect check every injector where they go into the inlet manifold. Check all fuel hoses as well.
Sometimes a fuel smell can be somewhere different from where you can first smell it.

That sounds like bearing noise, but they might not be bad enough to fell anything different yet. Only way to tell is to unbolt your wheel then unbolt the brake caliber assembly, then turn the wheel hub around. To see if you can hear the bearing then.

That loud clicking noise could be lifter/tappet noise.

Clicking noise - Check oil level/quality

Fuel smell - Like Jim says, check breather hoses (I had strong fuel smell from engine bay little while back. Ends up mechanic replaced high pressure fuel line with smaller outer diameter hose, but used same hose clamp. Didn't tighten completely an p!ssed fuel into the cavities on the inlet manifold, filled them up completely. Still don't know how the thing didn't catch fire.)

Bearing noise - Also suggest check tyres for uneven wear/scalloping.

I think number 3 and your smell is a cracked header and stops making the noise once it's hot and joined back together with heat expansion

#3 fault.....is it manual or auto?if it's auto i'd say your flex plate is cracked,by the noise you have described.
