Small knocking sound Gu patrol auto

[craigv]

Help needed, have a 3l Gu patrol auto and have a small knocking sound coming from the engine bay area,It only happens taking off and not under load standing still in gear, it doesnt happen while the car is rolling along or over rough roads just taking of while the motor is under load, The engine is new I was thinking some other component like fuel pump.Has anyone else had a similar problem.Thanks

So does it sound like its coming from the engine itself or something in the bay ? Does it go once the engine warms up?

Who replaced the engine, could the engine mount bolts be still loose or something silly like that ?

exhaust bolt maybe loose though that was more a load rattle on take off only I experienced, dive under it when its cold & use your boot to nudge the gearbox, exhaust & motor, see if you can replacate the noise, engine mount bolt is a likely starter though

No it sounds like something in or under the bay but only happens taking off, it doesnt happen if its in gear and brakes on and put load on the motor or when im rolling along. The noise is there taking off on flat or rough roads quite bazzar

A Nissan dealer replaced the engine, ive shaken everything thinking it was the engine or gearbox mount but doesnt happen. Im just getting worried thinking it could be the fuel pump or something?
