hey im having a weird noise which sounds like a chook chook chook noise when i accelerate from a slow speed, the harder i accelerate the lounder the noise, i have removed the aircon and tge power steering belt and the noise is still there so i know its not them and i have felt the alternator and water pump pulleys and they seem ok, the alternator spins but makes a slight noise and i assume tgats normal cos its turning a generatir in it and the water pump spins ok as well but i carnt soin it as fast as the car can so i carnt be certain its not one of them making the noise, now the only way i can be certain is to remove that last belt and drive it for a minute to test it but im worried about driving it without circulating water running through the engine, does anyone know if it will ne safe for a quick drive to see if tge noise is gone

A very short drive from first start in the morning would be OK like around the block no further, if the noise is still there when the belts are removed then that could indicate a cam belt idler or tensioner bearing failure.

thankyou so much for your help, yeah it will just be to the end of my street and back, i live in ballarat so the car is very cold right now and so am i hahaha

and yeah im hopeing it goes away after i remove this last belt cos i did think about the cam belt or tensioner and i know i do need to get this done soon anyways cos the car has done just over 100,000kms so timing belt is due for a new one

Well if there is a noise and you are due then its all gotta come apart anyway so if you book it in to get done you should find itll be problem solved ;)

the car is an automatic unfortinatly lol but it only does it when im taking off or going slow and then accelerate hard, if i really accelerate hard where the turbo kicks it its very very loud, but on the highway sitting on the speed limit there is no noise and its nice and quiet

Could be so many things mate! Really hard to do E mechanics on this one... Can you record the sound to help?

Could be in your auto itself, in the driveline? Could be your plastic fan hitting the shroud if an engine mount is gone or just so many things! Could even be a blown turbo gasket or something silly! Without hearing it its just a guessing game unfortunately!

the belts are all off right now cos i was going to take it for a 60second drive to check it out, if it was on i could record the sound and post it here. if i did drive if with no belts and the temperature doesnt get over half would that be safe, what im asking is it obly the temperature i have to worry about if i dod drive it quickly

you hit on something there actually mate, the turbo gasket is bad but i didnt think it would give a noise like this if it was a manifold to turbo gasket

You would be suprised what sort of sounds they can make when they are leaking under load!

ok your right i will put the belts back on and go get a gasket now if i can find one and i will record it on my way to get one, thankyou for your help and i will post the noise soon and let you know if the new gasket fixed it

Good luck with it mate!

You don't want it moving off the bottom of gauge, let along getting any where near half, your turbo is water cooled so you don't want to go on boost at all.

Better safe than sorry so you may as well NOT drive it, if it was your idler or tensioner bearing it will make the noise on start up and when idling, it will make a screeching sound that has a clear rotation sound, if its a turbo gasket it won't have that rotating type sound.

I would drive out a little with out the belt. It won't instantly overheat, the coolant will still thermo siphon through the engine/radiator.

Anyway doesn't sound like it is the belt anyway. Good luck sussing it.

Just a note that your gauge probably wont move at all seen as the belt drives the water pump. Most of the hot coolant will stay within the engine and you will only get a small amount of heat circulating through convection

You basically wont know the car is hot till you see steam or something breaks

    • 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. 
    • 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.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • 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
    • 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.
