Hi All,

I have a strange noise that's developed over the past coupla weeks and I dunno what it is.

It's like a whirring noise (sounds like a belt or a bearing) and it's coming from the front of the engine. I tried locating the source, but it's kinda a bit hard cos it's originating from the front where all the belts are. My best guess is it's coming from behind the timing belt cover. :P

The whirring noise only happens when I rev the engine. It does it while I'm stationary and in neutral. It gets louder the harder I rev the engine.

The timing belt has been replaced recently (about 3500km ago) and the idler and tensioner bearing has been replaced also (about 2500km ago).

I don't know what it could be but I'm fairly concerned, since the source of the noise seems to be from behind the timing belt cover. Luckily I don't drive my car too often these days (too busy) so it only gets driven 2 or 3 times a week. I'll be getting checked out ASAP, but the earliest I can do it is this Saturday coming up.

I thought I'd throw something here to see if anyone may know what's up...

Cheers

i have the same problem right now. Only after about 3000 rpm when driving, i dont notice it as much...

it comes from inside the cam cover, but it is hard to pinpoint! I took the cam cover off and still wasn't sure...

anyhow, it turns out it is the timing belt on WAAAAYYYY too tight!

Seeing as yours is new, you shouldn't worry too much, but get it done ASAP!!!

Take it to the mechanic that put it on and tell them to loosen it.

Mine has been on for 40,000 km, and nissan recomend that if it is a used belt, that you toss it once it has been overtightened.... So I told mine I wanted it replaced, I supplied him with a photocopy of the pages in the service manual that exp-lain how to change the belt (just to make him feel like a dick), and I demanded the old belt also be returned to me.... :P

Reduce the options. Start by droping off one fan belt at a time and listen for your noise. Power steer, drop off the belt. Alternator or water pump, drop the belt. Air con or belt tensioner, drop the air con belt.

Still got a noise, it's in the cam belt area so you can take the next step.

Of course don't run the bloody thing for hours without belts!!!

Regards.

one thing i have found when the belt is fitted you sometimes get a bit of coolant on them if the water pump got replace and this causes a strange noise when it dries out and the residue is left on the belt. it only takes the smallest amout and the noise takes a while to start. what you can do is take out one of the top cam belt cover bolts and spray a SMALL amount of sylicone lube in there and that will stop it if thats your problem

I am relieved to report that the problem is a faulty fan clutch. It turns out the whirring noise is the fan over-spinning, since the clutch won't fully disengage. :)

Luckily the fan is still in good condition, despite having noticeable fractures on the body of the fan. The blades themselves are fine, tho.

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah 路 Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      R32 gtr transmission strength, billet plate

      By cosline 路 Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz 路 Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
