Hehhehe.. mine does that too! It's an electric tensioner on the seatbelts!

When the car is running, pull on the drivers belt... it resists a lot. Turn the car off... CLUNK! Now pull the belt... it's smooth with little resistance.

I pulled the rear quarters off when I removed my seat and ran wiring for my stereo, and the belt rolls have an electric something on it, with Australian branding. So I dare say it's an aftermarket thing that was fitted.

I have a pic at home if you're interested.

Pretty loud, yeah!

I haven't had it for a while now, because my alarm's turbo timer keeps the ignition going after i've taken the belt off and gotten out of the car etc.

But yeah, have you tried pulling on it with the car running and not running? Could you feel the difference?

yeah there is like a tensioner that only works when the car is going.

Umm.. no, I didn't. I found it when I made my new parcel-shelf. This is why a couple of shots are through the rear windscreen. =-]

The second pic shows the location. It's kinda under the parcel tray, but adjacent to the rear seat.

Oh, there's that little box that noone knows what it is for! Sits in the left bracket under the parcel tray in Series2's. The same bracket on the right-hand side is empty. Something to do with fuel, apparently.

But yeah, the seatbelt tensioner! Way cool, eh!? Looks to be an Aussie thing done, possibly during compliance. I don't think there is any way to "fix" the noise, cause it's a mechanical device. You could try unplugging it and having just regular spring-tensioned belts.

There is still a spring in them like normal belts, so this should work, and the teeth that grab the belt if it moves a certain speed should still work too. Best to test this though.

The third pic is of the front passenger belt. I had the rear passenger quarter-trim off to fix some broken clips and to run some RCA cables. It too looks to be wired for something, but it is not noisy, only the rears in my car.

Hope it helps! I love gadgets!

No worries... i've never seen it in anyone else's car, and noone seems to have ever heard of it before, but from what you describe, it's EXACTLY what mine does.

VERY lound clunk, and that seat-belt tension thing is wicked.

yeah my first though was it had sumthing to do with the seatbelt tensioner thingy, but its hard to explain what it is to sum1 who has never heard it. my mate were like "WTF" when they first heard it.lol i didnt know what to tell them, just said it sounds like the seat belt thingy to me. :D

My 33 has these seatbelt tension thingys too... but they are connected to a wire under each front seat... looks like they used to be connected to the seatbelt socket thing. When the ignition is on, i can short the two pins on the blugs under the seat and there is the loud 'clunk' noise that you speak of. I've never really noticed too much of a difference between shorted and unshorted, but i'll have to try it out!

It sounds like yours are perminently shorted, so they always clunk when the ignition is turned off... try looking under the seats for a cord, and see if there is anything causing the two pins to be connected (the one on the passenger side is easiest, as it only has two pins, the drivers one has four.)

Okay, couldn't resist the temptation :rolleyes:

I went out and sat in in my car, turned the ignition on, and shorted/unshoreted the pins on the seatbelt connector... The belt seems to slide pretty much the same, although with the pins sgorted there is a slight ratchet-type noise when you pull it, whereas without the pins shorted it is quiet... I can't feel any more or less resistance either way though.

I think the "clunk" noise means that it's working, because mine will do it with ignition, and also if I press the seatbelt release button. Oh, and there is a definate change in resistance...

I think when the new compliance rules came out, the seatbelts had to be changed, whereas mine has the original jap belts according to the tag.

i have this also. i would've sworn black and blue it was hicas locking itself or something like that... i'll have a listen for the seat belts next time i have someone else near by to turn off the ignition. i'll jump into the back seat and listen... very interesting.

      Looking at the photos, you could easily just drop this pipe and dump into atmosphere  Just 1 or 2 quick hits for data acquisition - if have a heat shield material and/or sheet metal, maybe just use wire/metal cable ties and attach it in a way to deflect heat from melting nearby wires.

      Yes, well, keep in mind that the air is intake air, which equal boost + possible oil. If there is a fine deposition of oil/scunge that then gets hot and carbonises, it could look just like that. Probably shouldn't be leaking. Might just be normal for that product. Hard to know if it is relevant.

      Wrapped up putting the motor back in today. I have a stainless flex turbo drain pipe like you see on cummins and that funny enough PRP started selling. I generally prefer these but sadly they come with a finite amount of times they can be bent before they snap. Took well over a week for a replacement to arrive.  I was able to prime the pump but I will more then likely wait until next friday to take it on its madden voyage. I also installed the nozzles for my direct port WMI setup but plugged the nozzle holders for now. I'll tube it with Swagelok SS tubing and fittings next chance I get. No rush, i'll be breaking it for a week or two anyways.

      I could definitely do some logs without the VCT enabled for sure. I believe we tried it on the dyno and it still spiked but wouldn't hurt to try again and have the logs    I might be able to use some metal cable ties and hold the gate open entirely, I'd need to see about that one.   What do we think about these marks on the cap of the actuator? This is where the two parts push together where the diaphragm spring is. To me they look like air has been sleeping past?? Specifically talking about those black stains above the lower rim/lip. They can be rubbed away as if it's just an exhaust stain.
