Hey Guys,

Chasing some help here if possible for those more knowledgeable than me. I puled of the CAS unit on my 25/30 motor to fit the front cover back on. I marked on the head and the CAS to make sure i mounted it back in the same position.

I decided to turn it over and heard something break so shut it down. Pulled it all apart and it seems the "Half Moon" nub on the end of the cam where the CAS sits broke off.

My question is, is it possible to line the half moon on the CAS with where it sits on the cam and line the markings on the outside of the CAS & head and it all be fine? As far as im aware its the teeth on the CAS that keep it in place and rotating and the half moons are just there to assist sitting it in there.

Once back together i turned it over and it idled fine. Took it for a drive and all seems exactly the same, nothing seems to have changed.

Whats everyones thoughts on this? In my cam f**ked or should it be ok.

Any assistance would be great.

Pretty common issue. It can be done but must be spot on. As you said the teeth engage the CAS and the halfmoon just locates it so it will still work without the half moon.

My suggestion is to get some loctite (or similarly good) superglue and stick the half moon back into position then install the CAS. The superglue should hold it well enough to get the CAS on. Start the car and check base timing to make sure its right

      Will I Need A Retune After Cahanging My Catalytic Converter ?

      By silviaz · Posted

      Does it make a difference in your turbo having a shorter life if you have a cat converter as it causes that back pressure versus less/no back pressure with a decat? (Not sure if this is accurate) Also slightly different question if you went from a oem cat to a decat or vice versa will it require a tune? I heard if you change the dump pipe onwards it requires a tune?

      Need AC Compressor for R32

      By GTSBoy · Posted

      No. Have only gotten as far as contemplating the task of having to put in the required fairly heavy wiring and fusing to run it (along with the big alternator), and preferring not to. But otherwise, it would be nice to have a little extra freedom as to exactly where the compressor is located and free up some space around the exhaust side of the engine.

      A little PU bush story

      By GTSBoy · Posted

      Following from this in a related by not closely-related sense... Because I was buying a bunch of other GKTech stuff, I got some rear subframe collars. The history that leads up to this is: 25+ years ago the car arrived into the country with stock subframe bushes. At some point shortly thereafter I added Whiteline pineapple rings, set up neutral, and it improved the rear end behaviour. Well, it is my vague memory that I was happier with it with them in. Less axle tramp on launches, generally better, etc etc. ~2012 it got a new non-HICAS subframe with new stock bushes. No pineapple rings. I reckon that ever since then I've been dissatisfied with the axle tramp. Recently I've been f**king around a lot with all aspects of the suspension. One contemplation has been to relocate the rear lower control arm front mount points (and do the other things needed to make that work) to improve longitudinal rear grip by getting rid of some of the stupid anti-squat that Nissan ladled into the R32. But.... before doing that I thought I'd put some collars in. And.... The collars are good. The rear sounds a little bit different, but there has been no significant increase in NVH coming up into the body. In terms of rear behaviour - expansion joints on long sweeping elevated freeway ramps that would sometimes cause the rear to jiggle around a bit, no longer seem to do so. It appears that jamming chunks of metal into the gaps in the rubber so they can't move much is a really good thing. And the launch behaviour and general forward traction situation seems to be greatly improved too. It's impossible to be really sure, because the tyres are completely shagged - they are freakishly willing to let go right now. But as an A-B test with the same tyres it certainly seems to grip up a lot better. Highly recommended to anyone who still has stock bushes.

      Need AC Compressor for R32

      By PLYNX · Posted

      Bit off topic maybe but has anyone had a crack at one of those aftermarket electric compressors ? Bit of a search came up with one put out by Speedy Air Spares. Looks interesting and looks as if you'd have to run a big arse alternator. Found this out after the fact as my air con compressor packed it in and soon after my alternator ! !

      Need AC Compressor for R32

      Yes. Needs new ports. Usually just achieved by screwing an adapter onto them. Be aware that any AC compressor that hasn't been used in a long time will very likely have dried out seals and will not hold gas. Oh, and obviously you will require a new receiver-dryer also.
