got one for you all, thought id solved it a long time ago but when we had my gearbox out noticed i hadn't

 

i've got something leaking down the back of my engine, its more on the passenger side, and its getting onto the earth cable on the gearbox, (N/S top bolt)

 

its not obvious what it is, what is back there that could do this? i've only seen smoke once the engines turned off about 10-20 seconds later??

 

what i've done...

 

i've got Z1 silicon heater hose so there not leaking,

rocker covers are a couple of weeks old,

the turbo oil and water feeds were replaced a couple of months ago whilst the engine was out.

i have bypassed the plenum water pipes.

PCV pipes all new.

 

anyone got any suggestions what to check now?

 

slowly making progress with this car now lol.

Might narrow it down a bit of you say what substance youve found to have leaked lol, oil, water?

cant really tell, looks like water, but smells like oil,

So its oily water :biggrin:

 

I would double check the turbo feeds, although they were replaced, might need a nip up, as they are under great pressure, even a seep is enough.

 

 

bit high up for turbo feed?

Right, when you say rocker covers are a few weeks old! did you replace the rubber gasket on the inlet rocker and renewed sealant on the ex cover?

Looks like you have an oil leak out the back of the vvt solenoid or around it.

yeah new Nissan gasket on inlet and oil resistant silicon sealant on exhaust side, all 4 covers,

 

could it be leaking from under the vvt solenoids? is it easy to remove and is it just sealant round it?

Before you start removing the cover again, run your finger under the back of the solenoid and see if you can feel the oil.
