I recently removed my rocker covers for a clean and coat of high temp. paint, I've put it back all fine from what I can see but here is the problem..

While the turbo is spooling I can clearly hear the turbo sucking in air (Good ol' pod filter) but I can hear a strange and unique sound similar to an air leak or soft buzzing eg. zzzzzz

It's completely diffrent sound compared to the turbo spooling.

I've checked the cooler pipes and all necessary hoses for any leaks but couldn't find anything. I noticed at high revs I'm laking power, especially in second gear.

All I can think of is there some kind of air leak?

If anyone can help it would be much appriciated, i just want to see if I can fix this problem before I take it to the only mechanic I trust which is a good hour away.

Many Thanks

try the turbo to exhaust manifolds nuts for tightness - could be the exhaust-turbo gasket buzzin (sounds like a dying rabbit) inbetween the joint. Pretty common especailly if it happens as turbo builds boost (more pressure in manifold!)

Thank you for your help but...

Where are these located exactly?

Cam covers, you took them off to paint them. Skylines don't have rockers, so no "rocker covers", they have "cam covers".

There is one pipe between the cam covers.

There is one pipe that goes to the inlet after the AFM and before the turbos.

There is a third pipe the goes to the inlet plenum. The PCV valve is on the side of the RHS (drivers) cam cover, the hose goes from it to another fitting on the inlet plenum.

Check those 3 hoses and their clamps:cheers:

    • I dunno about that as a blanket statement. Pitwork is Nissan's "Nissan genuine" thing, and for stuff like timing belts, I have found them to be excellent. Of course, for things like oil filters, you always use proper trusted brands anyway, not whatever the OEM has taken to using.
    • Ahhhh... If you were putting 12V to the led in there, that's likely made it very unhappy. Chances are how you put power, was 12V across an LED that's meant to only have about 20mA through it at peak, and a forward voltage of about 1.8 to 2.4 volts. That circuit is likely only a 3V3 circuit, and will have a resistor in series with the led too. That's my guesstimate on that light, without having touched one.
    • Another vote for installing them and see how you go.  I mean, you already own them, why would you not fit them? 
    • I have had too many of those over the years, my cars have a toolkit or at minimum a cheapy multi tool thing because its too easy to be snookered by some stupid plastic clip that stops you checking the battery terminal isn't loose.
    • Basically, if there is a part# on the nissan catalogue, it is a genuine part. There is a thing called "new old stock" which is stuff made years ago but never sold (or landfilled), but it is super hit and miss what you can buy. Other than some expensive Nismo stuff there is nothing new being made that suits these cars. The only time to be a little careful is (mostly in the US I think, but maybe Japan too), Nissan started rebranding some cheap crap maintenance parts like oil filters as "Pitworks"; stay away from them, if you are buying cheap just buy whatever the local car parts shop carries The three part numbers have an explanation on Amayama: 0V005 is auto, base style 0V015 is manual 0V505 is auto, hectic momo branded ones, maximum F&F points there!
