S15 Tractor Noise

[sovanarath]

Hello everyone

I've experienced this many times, when my car is idling it'd sound like a tractor. Sound occurs quite frequently and some days it'd sound perfectly fine. When i release the clutch to the clutch point and give gas it goes away.
I've done a few research and found out it had something to do with the vtc unit, solenoid?

Could someone please explain to me the problem and whether this problem is serious and if i should take immediate action.
A price range would be awesome too (NZ)

Thank you

More than likely the VCT, common SR20 issue. It was a basic design **** up from nissan, but as far as I'm aware doesn't cause any damage, it can just get irritating. If it really annoys you, then you can fork out for a new solenoid (if you wanna pay a price). Nissan never released a fix because it doesn't do any harm. I have heard of them going at 20k milage and I have heard of others not going to 100k+

Haha thanks so much for the reply.

It does get irritating, especially when people look at your car and they have that expression on their face like 'wtf'. Well no biggie, since it's not a problem i'll just leave it as it is. Also i don't think my car has any problem with the noise whilst traveling. Glad i don't have that problem, if so it'd be a pain in the ass

No worries mate! Yeah, it should go away when you start on the throttle, just an annoying idle.. I get people asking if mine is broke a fair bit, but that's my 2 way diff having a bit of a clunk at low speeds

Get it sorted, as it is only going to get louder and worse. It is possible to remedy it quickly and cheaply.

I had this problem in another sr20det of mine. I replaced the VVT( or CAS depending where you're from), tuned it and changed the chain tensioner and the issue went away

I can't afford anything right now so if it isn't a major issue then it's fine by me.
Unless the repair is cheap then i'd have to take that into consideration as it does get really loud sometimes.

Just disconnect the plug from the solenoid if you wont it to go away, you will lose the VCT in the mid range though
