as i said, jack the car up, top it up with water and run the car, look under the motor and try and work out where its coming from.. eg front, back, left right.

You say its coming from the back of the motor, so it means more then likely its a hose around the back, there are several that run around there, turbo line, heater hoses and so forth... the fact its doing it just after its running means its a small split in the hose and the pressure in the system is causing it to leak.

once you have found which hose it is its a matter of getting a replacement hose and replacing it... all the hoses at the back are a prick to get to but not impossible,

I should have some time tomorrow so i'll see if i can get down there

its coming from the back left of the engine, the dripping is coming from just above the starter motor. i dont have a decent jack so i cant jack i up enough to get underneath the car and have a look. its def coming from above the starter motor but.

I had a problem similiar for a good couple of years.

When I pulled the old rb20det out I replaced all the hoses with new nissan stuff. Cost me a fortune. :S

New motor went in and the little hose that connects to the turbo water feed that runs around the back of the head and the little hose that connects to the thermostat housing; both leaked over night when the motor was cold. During the day when the car was warm etc it never leaked.

I spoke to my old man about it who's had a little experience in the truck and bus industry.

He said they had the same problem that resulted from the manufacturer changing the rubber makeup.

He said hose clamps are available that are sort of spring tensioned so when the hose gets cold it prevents leaks OR the other fix is to dap a tinny little bit of silicon on the metal and then slide the hose on and clamp it.

So silicon it was and not a leak since. FYI I did try multiple hose clamps, new hose clamps etc. ;)

lol good luck Darren :D wernt you selling your car anyways ... sudi arabi wont need a heater

Yeh i know! Not sure about the selling of her yet, see what happends after summer! Besides i'll have a new corolla around christmas time :) Thanks Dan!!

Who wants to take my dash out and fix my heater??? LOL Just jokes, but it does need fixing by next winter i think!!

I just ordered this:

Will get Boostwerx to do the job..... poor souls. apparently with autos you can do it via the glove box (degas/regas a/c).

Currently my unit is disconnected and bypassed. All the fluid from the core found its way thru my carpets :laugh:

ive done a heater core on a r33 my sons what a mongrol of a job altho now i know where all the bolts are prob would not be too bad 2nd time around . i was told 300zx heater cores are the same as r33 ones. we paid 180 i think from the local nadrad dealer for the core.

My leak got a shat load worse on friday night, so im like nah F this ill take it to a workshop (friends of the family). after being in the shop for all day saturday and 200 bucks later i get my car back minus the leak. i did next to no driving sat night, sunday morning i was driving back from the shops and i can smell coolant burning, i drove really slow back home watching my temp gauge carefully, as i pull in it hits the "H". pop the bonnet to find another split hose :laugh: the top radiator hose.... another 10 bucks later i got a new hose on there.

no leaks so far but now im to scared to drive the car :S incase of another.... something or rather shitting itself under the hood. my question is, was this a coincidence? or do i have a more serious problem that needs attention?

any advice or thoughts would be awesome :D

    • I am getting the same issue. Did you resolve it? I just got it after installing my new super coppermix and literally the same issue, new fork, new 18mm carrier, release bearing that came with the kit and replicated the exact same sound. 
    • If you like - I have the STL files so I can email em. There's a couple of gotchas (i.e the holes are not threaded so you might need/will need) to utilize some M3 melt-in threads for some of the points. However if you want to be super accurate, and are willing to remove your calipers and your SHOCKS it's a really good tool. You also might need to scale the part that measures the tyre width a bit wider. It defaults to a 7.5in tyre and I mean who is running that. Luckily with the magic of CAD this is very easy to rescale.
    • jeebus. glad you weren't under it while performing the stunt. Also thanks for the link to the wheel measurer, exactly what I needed
    • In the older stuff there were very significant differences 2wd to 4wd, for example Stagea had strut front end for 2wd and double wishbone for 4wd so it was not minor to swap. From poking around the 2wd v37, it *looks* like it might be more possible; some of the parts specifically have "2wd" stamped on them which suggests the platforms are more similar. You'd still want to start with a 4wd half cut to swap stuff from though. I'd suggest if you don't have a tune on the ECU you don't really need one on the trans either. Throttle mapping is in the ECU side (and you can always use a Roar Pedal if you want the throttle to actually respond to your foot), and really if you are happy with the stock power you probably accept the stock trans behaviour too....its all made to be "sporty" not racey.
    • So, updates. I have not washed the car since it came back from Tassie. I've driven it around a bit but not got around to actually sorting it out. I DID raise it because I cracked the rear bar leaving a hotel which was very distressing. Interestingly, the car drives more compliant now that it's raised a fair bit (5mm front, 15mm rear). Also noticed that my FR height was 10mm lower than FL. So that's now sorted out, too. I also bought this and had it printed: https://www.etsy.com/au/listing/1576422240/wheel-and-tire-fitment-tool-universal?ref=shop_home_feat_1&dd=1&logging_key=08f604d9fa4cc383550ba985e6ac85cd5cac7fbb%3A1576422240 Now, if I was smart I would have taken my brake calipers off to actually use this correctly but it was evident enough to me that in the region where the caliper was... there was nothing to hit suspension/guard/arm wise. So I'm going with "it'll be fine" after using the tool to hopefully very precisely measure the wheel clearance. Also while doing this, I had the very VERY bad idea of jacking one of the wheels/suspension arms up while the rest of the car was on jack stands. I did this to see how the arm would travel. This all was well and good until the car slid off the stands and went through a fence. So don't do that. Incredibly nobody was hurt and there was only minor damage to the rear bumper as the car didn't have far to slide, and had 3-4 wheels on it. The only damage turned out to be the fence itself which was easy to fix, and a little bit of damage to the fibreglass rear bumper trim. I had already planned to try a touch up paint kit to fix the time I drove into my garage door to see if it'd help in the interim before I get it fixed properly. I used the Dr Colorchip kit after looking online and seeing everyone talking about it. Yes it's made for chips and not huge broken missing pieces and I'll be 500% recommending it for stone chips after using it for stupid things like me. This took about ... 10 minutes and looking at the half assed photo the 30 second job I did on the bumper corner was almost perfect just by using the tiny little brush and painting it in. The sealact stuff to remove over-painting is really useful, so if/when I do it again I'll likely slather the touch up paint well over it and then clean it up with the cleaning solution. The wheels should arrive in a couple of weeks. I am still kinda confident after doing a stupid amount of measuring (and borrowing a set of 18x10.5+15) that they will not fit because I overlooked something, somehow and flew too close to the sun. ALSO R34 GTR guard liners do not fit on a GTT. I bought the undertray brake duct guides and had the wonderful problem of them not fitting my intake, my oil cooler and the liners themselves were even worse. Attempting to fit them won't work in general - You would have to cut them up as another poster mentioned as the bodywork is different on the GTT. At least I can try to resell them. So instead of cutting those up, I cut up my old already-cut-up GTT liners and extended them by using some PP plastic and drilling some 8mm holes for some nissan clips for the 'extra' bit. Because I was happy to cut them I was able to mount them pretty damn forward so I now have some semblance of guard liners, and the brake vents seal the bumper from the bottom. It sort-of-looks like this, to give some idea - If you look at the GTR and then the GTT this is when I realised that I needed to seriously measure as the inside of the rim area is entirely, entirely, entirely different and could not take any internet measurements for granted.
