My FD3S overheated last night in traffic, it went to 120 and before i could turn it off, it went pop and made and loud whistling noise, steam shot out from under the inlet area at the back of the engine bay
Obviously i turned it off immediatly and towed it home.
I dont really know what im posting this for because i know its not going to give me a miracle cure and say everythings ok but is there a hose down in that area that could pop off?
Chances of engine damage? :2Confused
Hi Dele
Lets not condemn it just yet.
There are some small coolant hoses under the inlet manifold. Had one of these fail myself.
Find the broken hose, replace it, top up the coolant , and lets see if it starts.
pipes to the water heated manifold mate.... might have had a jubilee clip missing or something & just hapend to blow off when in traffic!!
Jono
120oC is where seal damage is possible, you might get away with it if you\'re really lucky but usually over 120oC and its damage time.
Get everything checked over and see if you got lucky mate :2eek
As said, there is a pipe leading from the block to the rear of the inlet manifold, near the secondary butterflys... the pop and whistling noise could have been the pipe splitting / blowing off I guess?!
Mine split a few weeks back.. a few hours to replace, altho my temps only got to 102 after i\'d switched the car off and it has stood without pumping water.
Good luck.
I spoke to the previous owner, he said he replaced that pipe and he doubts its that, but surely if it reached 120 then it wouldnt care if it was a new or old pipe it would blow regardless?
How would i know if i have seal damage?
Thanks!
The dreaded champaign test mate!!!
Just do a search & it will all be explaind!!
Jono
I\'ll take a look at it at the weekend,
I had to move it last night round the garage, i left it running for 5 minutes and nothing untoward occured, temp was fine, idle was fine, oil pressure was fine.
Hoping its just a hose and i havent broken the water seal!
I\'ll let you know
was there alot of smoke?
Sorry to see your having problems,
Wilst it could be almost any pipe on the water system that has burst or poped off first have a look at the pipe from the engine to the plastic AST tank in front of the engine as these are push on hoses, or you could even have a split AST tank which is common on older cars.
Hope this helps
I had an FD that rode around for a year after a pipe came off before the water seals eventualy expired, so all is not lost yet.

Just read the above,
You really need to drive the car to get the water flowing and everthing up to full temperature as I have found before that with the 3 small hoses on top of the engine, one to the throttle body, one under the throttle butter-flys
and one to the left of the altonator these may not leak on tickover.
The pop and woosh actualy may have been the pressure cap letting go.
Lastly, does your buzzer work ??????, if not you really need to mend this before you go any further so you know your not running an engine thats low on water.
You really really need this because if you still have the stock water gauge these are about as good as nothing and only warn you of anything untoward when it\'s far too late.
The thing is, under pressure, the system doesn\'t boil until 129 degree\'s. Great news on the face of it. However, as soon as something \'pops\' off or split open, it\'s no longer under pressure and will boil at 100 degrees. So, it\'s not looking good at 120 degrees. However, you may still be lucky, but i wouldn\'t expect it to be ok.
Mine did a similar thing, due to a split hose, but I switched off as soon as I saw it hit 102 degrees. Been fine since. And, obviously, that was above the 100 degree boiling point threshold and I was ok. So, you never know!
But if you run coolant then the boiling point is higher than 100°C, depends on the mix but 50/50 water / coolant should be about 110 - 115 at the least.
So you may be lucky!!!
wat psi pressure cap ar you running?
Ok,
Finally decided to go look at it today after letting it sulk in the garage for the last 3 weeks, started it up and left it running, then noticed when you blip the throttle theres a nasty gargling noise comming out of the air filter, checked all my fluid levels and they are fine, it hasnt leaked anything either.
There was also a slight leaking of exhaust gas in the engine bay, gasket?
Bad luck ...yeh, 120 seems to be the pop off point. I know mine did, just had to take out one more car ar Brands :driving
My question is tho why did the temps get to 120 ? Sure things will pop off at 120 but why did it get there.
J.
No idea, my guess is that fan didnt come on?
I tried to move it just now, and guess what.
It doesnt start.
Thinking im going to sell up and go back to Skylines lol
Fan trouble ......... yeh, quite possibly ....... It does happen. When I first had mine one of the fans packed up and mine started to overheat in traffic.
Good luck, ......... not starting is not good ..... if that is not stating the obvious :Hammer ..... When I blew my pipes off on track going over 120 degress it got me home but when I tried to start it a few days later it wouldn\'t start and the water seals had gone.
J.
I checked the fans just now, they both come on fine, i took it for a drive down the road and the temp rose up too quickly for my liking, again i turned it off before it hit the red
When i stopped it i could hear it hissing and see it steaming once again, i opened the bonnet and it appeared to be comming from a small black box/cover just infront of the inlet, in the middle of the engine, ive got some pics ill post them later.
So all the money i got for christmas is going to be spent on fixing my car, seems a terrible waste lol
sounds like its coming from the hose behind the water pump housing..
how far up the gauge did it climb?
Before i turned it off?
Just below the red
oh no :(
sounds to me like it might already have had it.... :(
sounds like u got about 120 degC which aint great for a rotary.....
if it had already had it surely it should be ****ing out dirty amounts of smoke?
(which it isnt, even slightly smoking)
im just speaking from experience on one of my engines that did that ..... failed within 500 miles.... :(
Anyways, lets not condemn it yet.... get those hose changed and see if it makes an difference....it definitely sounds like the hose that goes from the back of the WP housing to the rats nest...its a sort of L shaped hoses if my memory serves me right...and youll need to remove probably the alternator, water filler neck, water pump and possibly the airpmp to get to the water pump housing...i think you then got to undo all the nuts holding the WP housing to the engine and then pull it forward to access the hose...even then i ant remember if you need to remove the plenum for access or not!
Also what psi pressure cap are you running?
Dele.
If its the hose i\'m thinking it may be, its the one from the back of the stat housing, it may be split! i replaced mine, i think you only need to take off the Alternator, have a look in \'search\' for \'Thermoswitch mod\' by Bob picture no 10, you can just see the outlet from stat housing on the very left, from the red arrow, it\'s only a short hose, the other end is under the Alt, best use a Mazda hose. best not to run it till it.s sorted, good luck, Bob
Hey guys,
Thanks for the replies, i havent really run it at all since this has happened, only to move it from the garage to the drive and then to clear the over fuelling, not been thrashed or anything.
Im not mechanically minded but luckily my mate is so ill get him over and we\'ll investigate, im pretty certain its a hose that blew because the "pop" did sound like something blowing, nothing metalic.
Will let you guys know :Thumbsup!
Overheating is such an issue with rotaries I\'m surprised that many people still do not upgrade their guages to give themselves an early warning. The problem is very well documented and the choice of guages is plentiful. I\'m a great lover of original ( or as near a dammit ) classic cars but one of the first jobs after purchase was to fit quality guages. All my SAGA guages have alarms set to go off prior to any serious issues developing. I\'ve set the water guage alarm to 95C as it should not get that high during normal running, winter or summer. You cannot fail to miss the alarm when it goes off :2eek
This ain\'t gone to help your current situation but I hope its a near miss and your motor has survived unharmed. Good luck and HNY !!:cheers

Ok, i took a look at where the steam was comming from (circled in the first picture) then had a look inside
I found one pipe that looks like its disconnected completly, which i didnt think was right because of the obvious, and because there was one identical next to it that was attached.
Then afew centimeters next to it was another pipe that has split where it connects a metal pipe, the line is to show where the pipe leads
Sorry for the poor quality, its my camera phone, hope it helps

Ok, I cant see the split pipe, but it could be a water feed for the Turbo, these do break.
The other blank pipe you show is normal, its only used on an auto.
