Hi,

I have this issue with my non skyline, whenever it is warm it blows a bit of white/gray smoke and drips a bit of water (when fully warmed up ) and if u hit the throttle water shoots out 1 metre+ and smoke everywhere. There is no coolant in the oil, no oil around the coolant cap, its not losing any noticable amount of coolant, oil looks clean, idles fine and has what i think is all its power still. What could this issue be ? Cracked head around the exhaust valves ? Its DOHC alloy head which has ~300k kms and does have visible cracks on the back of it but they have been there for 50k kms and it never blew smoke.

*I did rebuild the engine 20,000kms (not the head)

Anyone any ideas or even come by have a look im in ghunghalin area.

If its a cheap runaround throw some bars leak into it. Warm the motor up and then take it for a gentle drive for 30 minutes. Should fix the leak.

I'd say you have a coolant leak into one of your cylinders and it only happens when it warms up. So you basically burn the water and it doesn't make the sump sso also the oil. It will get worse though and will do it eventually so its important to use the bars leak now. Chemiweld is another brand.

You think crack between cylinder hole and coolant gallery or just headgasket? If its headgasket or head i can do it in a few hours no worries but if block would be sad wasted time but i gained lots of knowledge from rebuilding myself. How long the chemiweld will hold ?

Engine is 4AFE series 1

if she still runs a treat maybe its the colder weather. more moisture in the air. all the hydracarbons in your exhaust the CAT turns to water/steam so maybe its just abit more due to ambient temperature cooling the steam down before it exits the exhuast??

also NEVER USE BARS STOP LEAK! its like kitty litter in oil and all it does it block anything and everything it can and turns your cooling system to chocolate milkshake. if you must, use a product called "stop n go" or "seal n go" (cant remember it exactly) which is a small clear bottle with copper looking gliter in it and its actually liquid glass once heated and sets hard and seals cracks in heads and blown gaskets etc "for good" they quote. worked for 18months on my shitter falcon which had blown all the water jackets out the exhaust side of the block and no1 cylinder (head is off now but needed it to runs for a few more months at the time)

If thats the case, than those cracks on the back of the head may have opened up.

Also lol at even turns

:thumbsup:

lol it was even and very tight :P worked alright for first 20,000 kms :P

might try the seal and go and sell it to some unsuspecting person ? or is that mean

was flushing the engine for the chem-i-weld i bought and noticed bubbles of coolant near the 4th cylinder on the exhaust manifold gasket :O that means the head is cracked yes ? did the chem-i-weld the smoke got considerably less after running for 30mins now i will give it a week and maybe do another later

No more smokes now i drove from gunnghalin to tuggerz with no problems (apart from 30degree diff freeplay) but no more smoke. Radiator did look like it was being blocked by the chunks in chemi-weld but seems to have dissolved now. Thanks for the help guys :) now i can not put 1200kms a week on my skyline

hooray! hahaha!!! the mechanic in a bottle works again

yeah fuark im heaps amazed . it completely stopped smoking couldnt even detect the tiniest amount :O think im gonna keep it in there for another week before flushing coolant again, hopefully will last till summer when i will have the energy (and not freeze) to replace the head.

thanks again :) (no homo)

      By oHBoy. · Posted

      I had 3 counts over the last couple of weeks once where i got stranded at a jdm paint yard booking in some work. 2nd time was moving the car into the drive way for the inspection and the 3rd was during the inspection for the co2 leak test. Fix: 1st, car off for a hour and half disconnected battery 10mins 4th try car started 2nd, 5th try started 3rd, countless time starting disconnected battery dude was under the hood listening to the starting sequence fuel pump ect.

      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.

      J50 clock date suddenly reset to January 1

      By suko · Posted

      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.
