Today i coming home from work and i noticed big plooms of blue smoke billowing out of the exhaust when i accelerated. The temperature guage was also right at the top. I pulled over checked the oil, it looked a little low so i filled it up and waited until until the engine cooled down. I drove a little further and noticed the temp guage still up high and smoke still billowing from the exhaust. I drove it to a petrol station and opened the hood. There was steam coming from the reserve tank for the radiator. I poured water in the reserve and then opened the radiator cap with a cloth over it, it hit the bonnet with the pressure, there seemed to be water in it. I filled it up and noticed there weren't any leaks. I drove some more and still the blue smoke and temp guage high, i stopped again and then i noticed a hissing sound coming from the engine.

Was wonder if anyone has any ideas about what might be happening?

Best regards, Rob

has to be either leak in hose or you got a blockage if it doesnt appear to be leaking ...had simular problem with my old car (prelude) ended up beeing bulk build up in the radiator and started over heating ..i left the car for a day filled up with coolent and drove less than 2km's and BANG there goes me engine haha my engine pretty much set fire but it made a hissing sound from the coolent dripping out the overflow on to the hot metal of the car >> hope that helps

thanks for you reply. i think it is something far more scary though as i left it for a couple of days and thenrefilled the radiator and noticed that the water was disappearing but i couldn't see any leaks until i noticed a small leak around the exaust manifold and that got me thinking that the water is going into the engine. Sure enough i tryed to start it and it won't even turn over not. I opened the oil cap and there is definitely water in the engine.

So where do i go from here? Is the engine completely stuffed? If not what caused it and how do i fix it up?

sounds like a headgasket went on you .... so was that the cause of the over heating or a result? hard to tell.

eitherway head needs to come off, you might as well clean the readiator and replace the thermostat while you there.

thanks for you reply, my dad said the same thing - so i went and checked the head gasket and the screws to the head were kind of loose. The gasket seemed fine but there was a lot of gunky oil/water mix. Don't know what it could be know.

Regards, Rob

any screws you can get to without removing the cam covers and using a 10mm allen key fitting next to the cams after getting the motor to TDC - hasnt got anythign to do with the head gasket.

sounds like you just tightened the cam covers down.

Thanks for your reply.

How do i get to the head gasket?

Regards, Rob

Lots of work, you need to take the cam covers off, the timing belt and most of the front [CAS, cam wheels, belt, etc], the inlet and the exhaust manifolds...........if you don't know, then take it to a mechanic. Attcahed is a jpeg screen shot of the manual, that should give you some idea for a R33. GL

Any water you can see in there will not prevent the motor from turning over. That's not to say that you don't have a cylinder or two full of water as well. Did the engine turn at all?? Did it turn and then make a clunk noise??

If you are asking questions like this and checking your head-gasket with a screwdriver then I seriously suggest you put down the tools and step away from the motor vehicle before you do any further damage and cost yourself a whole lot more than its already going to cost.

Tow it to a workshop and get a quote. Its not a job for beginners.

As for opening the radiator cap when you have just overheated your car???

There is a reason why they have a two stage release. The first click is to release the pressure so the cap does not fly off and have the coolant instantly boil and spurt out of the radiator causing serious burns to anybody who is nearby and unlucky enough to be splashed.

Thanks for your replies. I still want to have a go at changing the gasket as i see it as a good way to learn about how to do it. I have another car to drive in the meantime. So i wondering if there are any tutorials on this or other sites that anyone knows of and whether there are any special tools i need. All the best, Rob

Hello, just an update on what happening with my car. Stripped down the engine. Cleaned up all the gunk inside, head flat but a broken gasket, cleaned around surface and put back with new gasket. Cleaned injectors. I am wondering how to torque the nuts that hold the inlet manifold onto the head? Is there a special way to do this? Regards, Rob

u have an R31 with an RB30 right?? i used to have one of them and they are the easiest engines on the planet to work on, go to supercheap and get a workshop manual. pay $30 and it will have the head sequence and torque settings etc. get a good torque wrench about $50 and do the job properly. chances are u have warped the head but u might be lucky.

get some "HYLOMAR" at supercheap (comes in a blue and silver can) and spray it on the gasket before u put it back on. its good stuff and will help seal if there is a slight warp in the head.

also if u havnt already drain the oil and filter and replace the whole lot. it might have water in it as well.

mate, if u really dont know how to do rb25det head gasket, dont do it. it make worse. but if u really wonna do it ur self. i can guide u. coz i did my 3rd rb head gasket replace last week. any way where u locate..?

I poured water in the reserve and then opened the radiator cap with a cloth over it, it hit the bonnet with the pressure, there seemed to be water in it.

WTF were you thinking opening a hot radiator?! :P

why would u open a hot radiator like omfg not the smartest thing 2 do and confusing the rocker covers with the head again omfg.

im sorry if im sounding harsh but seriously u dont sound 2 good with cars and ur replasing the head gasket :P i can see it now ur going 2 try 2 start the engine and :nuke::):O:)

    • This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.
    • The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.
    • Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!
    • Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
