If your able to make it your self it will cost 1/4 of that cost. :)

~$40-50 for welding the 2 bungs in for the bov and breather then a little for the pipe (~$20) + 2 bits of silicon.

If the pipe is in 4" stainless then for a 90degree bend its around $40.

when i did mine i didn't have the catch can and i had the bov hooked up, would've been so much easier for me to make if i'd had the catch can on and the bov d/c like i do now. haha, heinsight's a wonderful thing!

Hey Ash,

Once all tuned up does yours fart and carry on with the bov blocked off?

At the moment untuned mine randomly when coming off the throttle to change gears pops and farts; drivability is fine; very little afm reversion and no stalls. I'm thinking off hooking mine up just to get rid of the popping and farting incase a mr police man is sitting behind at the time. :S

Cubes, I got my turbo 2 afm pipe on with my stocker blocked for the moment with no atmo BOV and it has a catch can installed.

I get backfiring, etc, but its a combination of my 02 sensor dead (reads like 0.02v at idle and randomly goes to 0.30 and then back to 0v while driving) and I have all those mods on stock ecu.

Kind of off topic but while on the topic of catch cans. :thumbsup:

I'm running twin catch cans temporarily to see how much it breathes. If its all good I'll be plumbing it back in. :) lol Reason for twin catch cans is its not as obvious.

So far its all super clean; not a single drop or smear of oil in the can or in the pipe its self. The single 1.5mm restrictor is definitely working well. :(

Pics...

Drivers side u can see how I've T'd in to the cam cover to PCV valve. Its just for looks; the PCV is blocked off.

Passenger side u can only just see the coke bottle with the hose going in to it. Both coke bottles have a modified top so they can breathe and filled with s/steel scourer. Hopefully I can't plumb it all back up as I really don't like catch cans due to being a big hit on the defect list.

If your O2 sensor is reading lean constantly unplug it.

Its telling the ecu the mixture is lean so the ecu dumps in more fuel. Your better off with it disconnected. From memory with it disconnected cruise afr's are around the 13:1 mark which isn't so bad.

Apart from the usual sponge and spray over at car lovers/BP no. :)

It looks clean as I just put it back together; I had the head off to be sorted as well as head oil restrictors and new turbo bolted on.

Give it a month and it will look normal again. :thumbsup:

Speaking of O2 sensors, I filled up last week and got a solid 350km out of her, I think mine could be on its way out....lol I could've sworn i replaced it about 2 years ago. How often have people been changing thier 02 sensors??

nah mine's fine apart from stalling after a while of driving and it defintiely runs richer but once tuned she'll be all sweet, i'd probably run the bov in your instance, u dont need any more response, hehe!

      Blue/grey smoke after idle

      By pacman_1219 · Posted

      Even with the piston at TDC there was room for it to drop, but I don't think it can drop fully into the cylinder, the problem you have is that you need something pushing against the valve to hold it up so you have enough room to put the new stem seal on and the spring etc.  I used compressed air only because putting rope in the cylinder seemed a bit risky to me, I know people have done it countless times before like this. Overall it's a pain in the ass job. Honestly you'd probably be better off taking the head off because the risk of dropping something in the engine and the finicky-ness of it all is very stressful. If you are going to attempt it though i 10000% recommend a 36050 valve spring/keeper tool. I had both the traditional lever type and after doing 1 cylinder it was absolute pain to get those valve keepers in place, even with 2 people. That 36050 is amazing, you do have to push hard to get them in place but it works perfectly almost every time. Back to my actual issue I think my engine is just tired and old and the rings have gone bad. The comp numbers (cold, no oil) were: Cyl 1 -129psi Cyl 2 - 133psi Cyl 3 - 138psi Cyl 4 - 137psi Cyl 5 - 157psi Cyl 6 - 142psi   Cylinder 5 and 6 having the most carbon on them.

      R33 Fuel Pump & Brakes after alarm swap

      Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?

      R33 Fuel Pump & Brakes after alarm swap

      Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.

      After market rear camber arm adjustment

      By GTSBoy · Posted

      Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.
