Hi guys, i have a 95 R33 GTST manual, and after driving the car for a while i can smell an oily type smell that leaks into the cabin. its not engine oil smell, its more like gearbox or power steering fluid smell. now im not sure what the gearbox oil would smell like when it heats up, has any1 ever smelt gearbox oil when its hot??? the reason i think its the gearbox oil is bcoz after driving for a while i think the smell is coming up from the gearbox. and i dont seem to be leaking oil anywhere on the ground. its a really strong smell that wafts through every now and then. any help on what it could be will be much appreciated. i know its a bit hard to explain smells.

I have this same(?) strange smell .. and it's gear box oil smell in my case

started happening when I had the gearbox oil replaced .. am yet to find the source of this annoying smell, there are no indications at all of a leak from the box

but I suspect it wouldn't be the rubber boot you suggest as there would be no need for this to be disturbed for a simply oil change, I had never had the smell prior to the oil change

I guess the first step would be to try another brand of oil

hmmm, funny this ... my car just started leaking coolant into the cabin (near the dash on the passenger side).  Has anyone had this problem before ??

this is not uncommon in imports, it is the heater core leaking, you need to replace the heater core, or else bypass it. it would be mostly due to the insides of your cooling system being corroded (like most imports)

Mine started about 3 weeks ago

Short term fix is to disconnect the heater hoses in the engine bay where they fix to the heater unit under the dash and fit a short length of 20mm pipe to join the 2 heater hose ends together

A/c will still work but no heater, this way you can still drive the car

I have removed the glove box and it appears you should be able to remove the heater section and replace

If you cannot get thru the glove box area to remove the heater unit, then the dash will need to come out

approx1-2 job to remove dash.

If you do have coolant leaking inside, you will need to lift the carpet up on the passenger side to get the under lay to dry out

Hope this helps.

cool guys, well i had a look today and i cant see any leaks on the passenger side carpet, the smell wasnt that strong today but when u drive for longer i tend to smell it more. will have a look under the engine bay for loose clamps 2moro. the power steering fluid seem to be staying topped up so thats a good sign. maybe the heater core is just leaking every know and then on mine not fully gone yet., also will pull apart the gear boot and have a closer look into tha seal thing. all depends on the time i have to look. thanx pred will do a search and have a read anyway.

haha my car has that smell. Same thing as wizard oz. it only started happening after i had my gearbox fluid changed. Only thing i could think of if the rubber boot thing got broken while doing the change is if they pulled the gear stick out to fill the oil up through there.... if they are really dodgy and you can do that in skylines. I used to do it with my old escort haha...

      Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.

      R33 Fuel Pump & Brakes after alarm swap

      By GTSBoy · Posted

      Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.

      @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html

      These going to fit over the big brakes? I'd be reeeeeeeeaaaall hesitant to believe so.

      The leather work properly stunned me. Again, I am thankful that the leather was in such good condition. I'm not sure what the indent is at the top of the passenger seat. Like somebody was sitting in it with a golf ball between their shoulders. The wheels are more grey than silver now and missing a lot of gloss.  Here's one with nice silver wheels.
