Ok I have been hearing a rattle from my engine and was wondering if you guys can help diagnose the prob? From reading others post in the forum I have come to the conclusion that is either lifters or an exhaust leak, maybe from the videos included you guys can help me diagnose better. Listen carefully and you can hear the rattle, 1)

2)

All suggestions are welcome and thanks for the help.

woah ..thats a very noisy engine. I'm no expert so i won't make any guessess... However my 34 GTT had/has a bit of lifter noise (mostly fixed up by oil change to thicker oil 10W40 recently) but it sounded like this one

I'm not sure why but your engine seems very noisy (almost like a V8 or a rexxy) and nothing like the lifter tapping noise as in the vid above

HMMMMMMM yea after watching that vid my engine does seem a whole lot louder than the engine in that vid. I am open to all suggestions so please let me hear them. Did the coilpack test all the coilpacks change the note of the engine so that means they are good or at least working and I am running all six cylinders. So please people help me out.

it sounds like your engine is idling normally, but its pretty damn loud. My first impression is exhaust leakage.

What is it like to drive?

My lifters are noisy when i start the car in very cold weather; sounds quite similar to the clip Denis posted. After a couple of minutes of idling the noise disappears

Well It still makes great power, haven't had it dynoed but it still feels responsive and it pulls nicely. Only prob I am having is when boosting at wot the car kinda surges and it doesn't get the 9psi quickly enough for me and if I run third or fourth gear out it overboost get like 13 psi towards the end of the rpm say like about by 6000 rpm or so, but I figure thats because the ebc is not configured correctly. The noise doesn't go away and upon inspecting my car I noticed that two of the bolts off the exhaust manifold are missing so far, at least from what I can see the first and last bolt.

I'd say so since they're part of the head ... try thicker oil first, that has fixed noisy lifters for a lot of people myself included (well fixed it 90%) I use Hi-Tec 10W40 (but any brand of the same viscosity should do the trick)

      Blue slip

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
