Hi Guy's,

Yesterday I drove my VL Turbo(Rb25/30 combo) back from Golf and got pulled over just before the Boronia Heights exit. The old girl has had a full rebuild and went in today for its first 500km service.

I was there with the car idling for about 5 - 10 minutes. Anyway while I was sitting there after a couple of minutes I felt a pop in the idle and within a couple of minutes it had changed into running like a pig on five cylinders. As I went to take off it was spewing out White smoke and chugging. I've had a blown head gasket before(Hence the rebuild) and seen White Steam coming out when that occurred but this was smoke. Temp gauge, oil gauge show all is good.

I limped it home and was contemplating suicide as all of my money is gone from the rebuild. Anyway had it towed to my mechanics today and when the towie turned up I had to move the car. Started it and it ran without a problem in sight.

The mechanic called and said he couldnt fault it. I turned up and witnessed him test it for a head gasket leak (The gasket is a metal one) but it passed with flying colours. Took it for a good drive up and down the freeway but she never skipped a beat. Everyone is like WTF nothing seems wrong with it.

Anyway last night I drove to the Brownstains video shop and pulled up which is on a slight incline. By the time I had dropped it in the chute and got back in the car there was that pop in the idle again. I started to freak out and started driving out of the carpark and the pop went and she drove home without a problem. Wasnt till I got home and thought about it I realised when I was pulled over the car was on an incline the same as the video shop.

Rang the mechanic and told him about my brain storm and he couldnt really offer anything other than maybe a dribbling injector etc but never heard of the car billowing out white smoke. I also spoke to JHH Performance who couldnt think of anything either.

The car is running a Haltech E6X(Batch firing not sequential injection), Slightly rich stocko tune for the run in, Haltech Ignition Modules, Standard Injectors RB25(Maxxed out), Standard Rb25 Series 1 coils, Standard Fuel system Fuel reg pump etc, Gt35/40.

ANYONE GOT ANY SUGGESTIONS OR SIMILAR PROBLEM. I DID A SEARCH BUT FOUND NOTHING THAT HELPS.

Cheers

I think the "white smoke" has everyone stumped.

White smoke is usually oil and water mixed and evapourated.

Usually foud in blown head gaskets (but the leak down test proved that wrong) or turbos (would be continuous).

.

I would check the colour of the smoke next time it happens and then report back.

>_< cheers :angry:

Yeh once I mention white smoke everyone goes aaaaaaaaaaaaaaaaaaaa nup no idea. Head gasket was what I was thinkin but the test dispelled that and it wasnt like steamy....... I did a search last night on here and some people have mentioned white smoke as unburned fuel which makes me think it might have been something in the fuel rail, injectors etc. It is running pretty rich.

I will see how it goes I was just hoping someone might have had a similar experience.

Cheers

      R33 Fuel Pump & Brakes after alarm swap

      By GTSBoy · Posted

      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.

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option
