Hi all, was changing my oil pressure sensor and broke the nipple on this fine can of emptiness last night, has 2 vac lines going to it... located under the intake runner/plenum thingy lol.

 

Thanks

Looks like your charcoal canister (part of the emission control system).

I thought that was the black canister located near the intake duct at the front near the radiator? 

Is there anyway to bypass this canister if so? or if its low pressure would super gluing the nipple back on work?

That is the vacuum tank reservoir for the dual plane manifold it stores vacuum and switches the length of the intake manifold from short to long for added power and no you cannot fix them, you need a new one. Try Partsouq they are usually awesome.

It is just a dumb canister though, isn't it?  In which case, anything of similar volume with a hose barb on it can do the job.  An EFI fuel filter, for example (with one of the hose barbs sealed off by your dodgy means of choice).  Or you could make one up out of a short bit of ~2" ally tube and some ally sheet if you're a fab nut.

Not quite as easy as that, the white part has a non return section in it to hold max vacuum attained. But what would I know I only sectioned one to find out what it did. Didn't you notice the other barb by his left forefinger. Talk about dodgy.

The variable intake actuator is activated via solenoid using stored high (idle or closed throttle) vacuum. The solenoid is activated on and off by ECU it is closed by the solenoid venting the actuator to throttle chamber (low vac at high revs) and closing it. At higher revs there would simply not be enough vac to operate the actuator.

Very early Chev's and Fords used them to run the windscreen wipers, they were common after market additions for old Holdens with low manifold vac (for advancing distributor) they are still made by Summit Racing but the original Nissan part is cheaper and available from Japan through Amayama.

      Duncan's V37.......race car?

      That is way more science than even I would use. I just eyeball it, not even accounting for the non-verticality of the tape measure when held on the lip and the centre at the same time. +/- 2mm is good enough for the girls I go out with.

      So, before putting them in I need to understand the stock ride height. This is how I measured it: First, check the diameter of the wheel's centre cap, it was 52mm. Then put a piece of masking tape approximately across the centre and measure 27mm (half) from at least 3 sides to get a reasonable idea of the centre of the wheel cap. Mark that with a horizontal line as one measuring point. Then, directly above the wheel on the guard, put another piece of masking tape in approximately the centre. Use a string line to find out the point on the guard above the centre of the wheel cap and mark that. Then it is simple, just a tape measure to check the distance from centre of the wheel to the centre of the guard. Final results where  LF: 381mm RF: 379mm LR: 401mm RR: 400mm Pretty even considering they are 120,000klm old factory springs, lets call that 380 front and 400 rear.

      So....knowing that I have a problem with power steering temps on track and another Wakefield day booked in next Friday, I've done the obvious thing They are very reasonably priced at $1650, considering they are a big monotube shock, double height adjustable (don't have to change pre-load to change ride height), one way adjustable damping and standard sized and customisable springs if you want something other than what comes with them. They come with 9kg/mm front and 4.5kg/mm front and I went with that as a starting point because I'll add adjustable sway bars too https://justjap.com/products/bc-racing-coilover-kit-ds-ds-infiniti-q50-v37-14-current#description Unfortunately they didn't come with rear strut tops so I've re-used the factory ones which was a bit of a pain. Also, the adjuster for the rear shock will be an absolute nightmare to get at, and while there are extensions in the kit I can't see any way you can actually attach or use them

      One Headlight isn't working - Driver Side Fuse Keeps blowing

      By Duncan · Posted

      I also had 2 bulbs blow at once, years ago in the stagea. made for a fun drive home. The issue was the voltage regulator had failed in the alternator and it was giving 15+ volts. Really, I was lucky all that was fried were the headlight bulbs. So, I'd suggest you check the voltage across your battery terminals with the car running and warmed up. Yes, you will need a multimeter to do so, sorry.

      Good work to think to check that, and thanks for coming back to post up the outcome.
