Hey guys,

as stated my car makes kind of a rattle noise when i rev the car just a bit over idle but the noise goes away probably at 1700rpms.

the engine sounds fine then it kinda goes *dud dud dud dud dud* but really fast, almost sounds like a bearing is gone in the cam cover.

a freind of mine said he was looking at a gtr and the owner said the noise was fine.

the car is a 96 rr33 gt-st.

any thoughts?

cheers

Possibly the cam belt is a little loose? My GTR made a similar noise that i coulda sworn was coming from the engine, Benno @ Racepace fixed it in about 10mins when it was there for other work. :P

Yeah i have felt that, and when i rev it by pulling on the throttle it gets louder then goes away after a certain rpm.

im buying a cooler and boost controler etc and i was gonna boost it to 12psi but i think ill wait till i get the belt changed.

hoping to have it done in a couple of weeks.

ill get him to do the full 100k service.

anyone know how much im looking at?

cheers

Mine cost somewhere around $400-500, but that was because the idiots at my local nissan dealer decided it was a good idea to take off the front bar, drain the cooling system, remove the radiator, change the belt and tensioner arm (i had asked for that), and then replace my radiator fluid with expensive nissan branded stuff. This isn't really helping but i'm just venting frustrations - originally they had quoted me about $200 or so.

Hi i think i have this same problem, Cam belt was changed 2 months ago, last couple weeks i have developed a rattle just above idle but only when cold, the noise is deff coming from the timing belt cover,

have attached recording, is this the same problem? any ideas on how to resolve?

(have searched many skyline forums and this seems to be closest to the problem)

Cheers

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
