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)

    • Yeah, so widen your search to any Nissan speedo first, then go wider if needed. I will say though, that there is a better than even chance that what I said first will likely come into play. They quite possibly won't come apart without damage. I tried to disassemble a stepper gauge that I wanted to repair. There was no way that needle was coming off the spindle, and I could not see how the spindle would come out of the mechanism behind. Assembled once, never to be disassembled, was my conclusion. Could be the same on the R34 cluster. Failing that - take the cluster to a workshop that specialises in automotive instrument work. There's usually at least one in every Australian city. They'll either be able to do it for you for small cost, or tell you it can't be done. It might be that "it can't be done" unless you follow some arcane procedure, including trickiness to glue it back together or something, that only experienced techs know.
    • Well, given that I, an engineer, almost never bring out the torque wrench to tighten up chassis bolts, despite fully knowing the theory, and instead rely on feel, which I happen to know is exactly how the majority of mechanics do things, should tell you the level of actual peril that exists from not achieving exactly 88 Nm of torque. How about if I just say then that 88Nm is at the lower end of the correct wheel nut torque range? Everyone knows how to tighten a wheel nut, right? And almost no-one ever brings out the torque wrench for that task
    • Don't be ridiculous. "2-3 ugga duggas or one Oof. You have to use Oof on tie rods because you can't get an ugga dugga on there." Is not helping the guy at all.
    • I have done a lot of research before posting here and on gtruk forum. couldn't find anything. I have my gauges all part except the needle itself. the needle has a extremely small hole in the center, but the shaft going to the needle is extremely small and appears to have nothing to index it either. doesn't seem strong enough to simple pry or pull without damaging something. Already tried the old spoon trick on a extra triple meter I have from a gtt, but no luck. the center cap comes off easily but the hole in the meter face plate aren't big enough to get over the needle itself. figured this would be my best place to find someone who might have actually removed theirs. wonder if there is some type of small pin press tool to push the pin in while pulling the needle base off.
    • Ok...its taking me long enough to finally do this.  Feck financial security...heart disease will get me soon enough anyway So welcome to the garage..."Clem" Belsil80 has been running a 370Z in Super TT series. So after entering with him in last years Winton 300 i figured I  need my own car. Seems SAU Vic race cars need to be yellow....{tick} Reckon with enough motor i will be able to make up for the lack of talent and stay ahead of the 370Z... but the LS powered S13 and E36s are a ways up the road Aim is to have a car that doesnt stop or turn but has a bit of shed built motor with jam...maybe some cream  First step is getting this ex drift car log booked I am keeping faithful silver car. As the road-club car gets upgrades the race car wil get the sloppy seconds
