Hi.
As of now i dont what happened(update comming soon)...but i just dont WTF was happened.
Head and top of the engine was rebuild last year...it ran great. I ran like 5k with no problems and car ran good when you take to consideration that is kinda slow have 216k km and is old.
But it ran.
Yesterday i took it to a trip and when i was near home i started to smell like burned plastic...i thought it is from outside. But when i stopped at the lights the smoke starts pour from under the car(engine)
So i stopped the car and take a look. My hood do not want to open so i try to look everywhere i could. I stall the engine and after like 10-15 min smoke was gone.
I saw nothing burned nothing smell ...nothing. So maybe some plastic melt or something "plasticy" drop on exhaust. I started up the car and it went good...nothing. No smoke no smell and car ran great. 
I was like 20 min from home so i ride.
But after like 10 min i started to smell the plastic again...and of course on the lights there was the smoke again.
Iam not going to push it but i need to stop elsewhere and. Car still runs normally so i ride like 2-3 min to park the car and call the "angels".

BUT then suddenly car make some wierd noise(i was low on gear and it sounded like the car was not happy on low gear and low rpm)...but then again the same noise and car just stalled.
I drifted to side of the road. Car (engine) was smoking.

I manage to finally open the hood.

Now what i found. There was nothing burned. Smoke came 100% from the engine. Car did not wanted to start (cranked 1 times...sounds bad) so i leave it. 
The radiator was cold...(like how?) there was no leakage as far i could se. Oil was at the top and do not look bad(was changes like 800km ago).
The back of the car(more near the exhaust side) was covered with oil/fuel? Something oily. But smoke or any type of smoke was really came out of the engine only...no smoke from exhaust(i looked at mirror constatly)

I know "magic ball" but WTF should have happened? Car was at the mechanics like month ago and he checked all fluids and any "service" things and all was good...and car was good runned normally until this happened.

@GTSBoy I "IF"...why? The gasket was brand new. Any reason for that? I do not race the car or otherwise abuse it. The whole "trip" the car has seen red(7k rpm) like 10 times max. I know that temperature gauge is not 100% accurate but it was at the center whole time(it should work...it goes down when the car is cold) so idk 😕
 

@Duncanidk i do not check at the time(my mechanic will) but i kinda dont think so...or at least not "much" cuz when the car stall on itsefl and i manage to open the hood the radiator was cold as no "hot" water was even there 😕 after like 10-15 min the radiator was starting to get warm/hot.
I have done brake swap from GTT so i checked everytime i ride for spillage underneath the car...and no drop. Even my mechanic looked last time(like 14 day ago) and car was bone dry ...no leakage or anything...

So i think something goes horrible wrong...again 😕 I know it is old car and things can go bad but i really dont know why this was happened.


 

Understood, but unfortunately a key reason for a cold radiator is that there is no coolant in it, it will just be at ambient air temp then....

It is way hard to guess without seeing the car, but coolant can look like smoke and no coolant feels like cold coolant

Most engine rebuilds are not that comprehensive purely for cost and time reasons. Also when it isn’t your engine you really don’t care that much if it’s messed up or not. Hence why everyone says rebuilds “let the Nissan magic out”.

The fact that your radiator is cold suggests you had a major cooling system failure. Within 5-10 minutes of driving it should’ve been too hot to touch with your bare hands. Coolant temp at the top of the radiator is going to be like 80C. Blocked thermostat or similar blockage in the system, water pump failure, etc can all cause these kinds of symptoms.

@DuncanI think so too...but dont why suddenly i start to loose coolant...but i guess that it is how things go bad.
The smoke was only from the engine...no smoke from exhaust. And when i checked the oil it was fine(no milky just regular colored oil)
Yeah i will see this week what went wrong.
 

@GTSBoyYou think it could like "self destroy" after a year? The gasket was done like year ago and i drove the car couple of k km. But i dont know how these things "work" and if it can go bad like right away or just like this...

@joshuaho96I know but do not have a choice. Not many people here gonna work on that car/engine (as far as i know i am the only with this type of engine). Most of them(even that still no many) have GTT and have no time or they want like fortune just for a small things.

Yeah i start to think so too...i know i touch the radiator many times before to check and it was HOT to touch..no it was only little warm on left and in the middle where the cap is...completely cold.
The "block" thing should have been the problem..or the pump but it is/was new...done with the belts and everything around last year.

I will let you know but i think too that something happened with cooling system.
But thanks for the tips guys 🙂 

Usually it happens again as the problem that caused it originally wasn't sorted properly, better off to put an import motor in than repair it.

The gauge won't show it's hot with no coolant because the temp sensor is dry, if you suspect it's losing coolant in the future try the heater on hot as they usually lose water out of the heater core early on so if doesn't blow hot it's losing water.

Happy new update(since last tuesday)
It was ONLY the broken hose from the heater core. Heater core was leaking so we took it out like month ago and just "connect" the hose until the new come out.
Being the 25 year old Japanese rubber...the hose do not like the new position and being "too" close to the exhaust(even with heat shield) and just broke.
So no HG no nothing.
My mechanic even told me(i did not know that) that Skylines have overheat protection when the engine starting to overheat they just cut the fuel...and that is what happened. Next day when the car was cold it started like new.

So at least something was not completely wrong 🙂

    • Did this end up working? Did you take some pictures?
    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
