Fuel lines under the bonnet maybe?

Coolant will go missing its just that when it cools it can suck some water back from expansion tank to replace it and eventually that will go dry. So keep checking it and the expansion tank level.

 

There are two short approx 3" hoses that go from just under the top water connection to each cylinder head. Mine had a leak there but you'd never find it with the engine just ticking over. You need to drive it quite hard then switch off and look with a small mirror and a torch. When the heat soak of the hot stopped engine hits the water jacket it will try to pressurise and any leak will show itself then. Keep squeezing the top hose just after its switched off to feel the pressure.

 

Mine now has a leak on a rear hose that wizzes on the hot turbo about 3 minutes after switching off good and hot. Makes like a steam engine! Now trying to find that one. You dont get long to search as the pressure soon goes and you cant see anything at the back of the engine.

 

As to the fuel smell, well that smell means fuel is spilling out. My bet is the hose down to the injector rail directly under the FPR on the rear right side of the cover with the Nissan badge on it between the last two intake pipes. You have to take that cover off to get at the hose connectors. Better still buy a couple of metres of high pressure 8mm fuel hose and replace every fuel hose you can find under there. The leak happens when stone cold, especially frosty weather when the hose is hard and inflexible - after 10+ years. The fuel pisses down into the vee of the engine then down the back of the bell housing and onto the ground right under the car. Take a look under the next time you smell it! Hope you dont smoke:)

 

Did mine a couple of years ago and no more smells.

Do you get a hiss sound when you open the fuel cap? If not means you ahve a leak some where.

 

I had a leak at the top of the tank neck. It didnt pour out but it did cause it to smell of petrol a lot.

yes the cap hisses when you take it off

 

cheers willie wiill investigate fuel hoses and water pipes

 

thanks for the info
