As the toppic states i have come into a bit of trouble with my r33 gtst series1. Yesterday after a short drive i realised a loud tapping noise coming from the engine i poped the bonnet and it was even louder. It seems to get louder when you apply more throttle but im no mechanic i got a long handled screwdriver out and listened through the end of it and could hear the tapping coming from this part . The pic attached is one i found doing a search. In Red is the part the noise is coming from and the the Yellow indicates the belt attached to it. Whatever it is it is causing the belt to split from the edges so the question is. What part is it? Is it still safe to drive? and how much to fix it your help would be greatly appreciated thanks guys, cheers.

Hi,

It's your air conditioning compressor.. Best to take it to a radiator shop or an a/c shop..

Thanks,

Scott Roberts.

If the noise is there when the air cond is not on it could be the idler bearing ( seized , dry etc...) , thats the pulley whre the red line meets the yellow (bottom part) . With air cond off check to see it the air cond compressor turns ( it shouldn't ), just the pulley should spin . If it turns the clutch could be stuffed, Anyway if you dont care about air cond , just take the belt off, when you fix the problem then you put the belt back on .

is anyone else worried that the ac compressor is bolted to the block, and the noise could be a spun bearing?

i could be wrong (i hope i am), but get that belt off ASAP so you dont do any more damage if it is a bottom end problem.

      Sorry, are coilovers ACTUALLY ILLEGAL in NSW? They aren't in Vic, as long as they retain 70% of stock travel and the car is above 100mm off the ground. Does NSW actually have a law making coilovers actually illegal? RWC/Blue Slip/Engineering people not knowing the actual f**king laws boils my blood. Demand them to point to the documentation that states a coilover is illegal. (it may exist in NSW )

      But seriously, can we ask for the results of the "tip a bottle of metho into a nearly empty tank" experiment?

      Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.

      Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.
