Hetes a couple of pics from the inspection point of my  04 350gt , all seems good in there ? Maybe im wrong but the guide doesnt seem to be broken or slipped down? Im guessing the small knock on idle is either a lifter or fuel damper, im going to run some thicker oil, if it stops the noise obvioisly its the lifter?

Can i get opinions on the tensioner it seems fine to me

Sorry, no idea about the tensioner.  I am dreading the day I need to do a tensioner or water pump on either of my VQs.

I have had the a noisy fuel damper and it was a constant knocking sound that changes with engine RPM, not just at startup, so if that is what you have, it might be the damper, hold onto the fuel hose on the right side of the engine while it is idling, if you can feel it pulsing in time with the knock, this is probably where the problem is.

Tensioner looks alright and its about half way out from my experience. 

Small knock at idle is not tensioner none of 3 and more likely it is the main chain that makes that noise which becomes louder around 2200 RPM 

I have changed all internals myself, all 3 chains, main tensioner, pump, VDCs etc

 

There is no need to use thicker engine oil stick with OEM Nissan 5w-35 Fully Synthetic

All those well known issues with main chains noises and VDCs are caused of exesive use of mineral engine oils back in Japan

      Old Son, did you re-use the Holden ABS in the new shell or try a different module?

      Another little story of weird shit happening

      By GTSBoy · Posted

      Yeah, nah. I had the actuator rod off it today. The arm will not move at all. Neither out, nor in. Yeah, you'd think so, but I've been thinking about that. Even when the actuator rod fell all the way off at the beginning of this saga, it would build more boost and faster in lower gears than it would in higher gears, and you'd think that that was the opposite of what should happen. But I strongly suspect that there is a thing with the gearing getting the revs to rise faster, that there must be some transient effect with the gas flow rate rising quickly, that you don't get with the more steady state case of the higher gears. Keep in mind - the gate is not shut in either of my weirdnesses. So things are not "normal". We normally think about a turbo spooling up (below the wastegate target) with the gate shut. I have all sorts of mental models running now where the gate is a little bit open, and having it stuck open allowing gas out while it should be going through the turbine has all sorts of weird effects (in these mental models). I'm thinking in the higher gears, the ex mani pressure builds to the point where enough gases spill out the wastegate to just prevent the pressure rising much more at all, or just creeping up, all the whole the revs are increasing and getting closer to the point where a gear shift becomes necessary.

      Is it possibly wastegate actuator itself is sticking, or even the rod to flapper? Otherwise I reckon things are getting a bit rusty/worn   Also odd it won't boost in 3rd to 5th, but will in 1st, I'd expect the other way around with it slightly open as there's more time on your way to redline for it to spin up

      Does anyone know ow what these two plugs are for and if they should be unplugged? Just put the dash back together and can't remember if these were plugged in before or unplugged! (Blue and white plugs) 🤦🏽‍♂️

      Looking for a part number for this part here

      By dbm7 · Posted

      Did some FASTing ...got the impression that the actual part# was a moot point ; seems all of these hardlines for coolant are discontinued/NLA... like, I take it you're after the hardline that bolts onto to the manifold...that's NLA according to amayama & nengun .... ...just to clear up some confusion, they typically mounted the AAC valve to the intake manifold somewhere near a coolant passage, so the body of the valve heats up & holds it open when engine's up to temp - no coolant flows through the valve, it's a mechanical, thermal connection.
