Hi Guys,.

Thanks everybody for valuable advices and help on. tomorrow i am going to tow it home,The heater gauge problem was there for few months,but i am pretty sure car didn't over heated and no even single drop of coolant from the radiator also, if that was the case i would have melted my engine,because of long distance traveling, cleaned the radiator also done last time,i saw the water drop before weeks time only, i think on that day the gasket would have blown ,

Thanks
Regards

make sure its not a corroded out timing cover and make sure all the water gallaries in the head are within limit

If your K's meant thousands than a few hundred would mean that you got your moneys worth out of your head gasket. but I suppose you are talking about kilometers.

If you purchase a quality "no-retorque" gasket, then you do not need to do it 100 miles/100 kms after replacement. With cheap gasket you may want to do it anyways.

Either way, Nissan recommends an semi-annual re-torque:

Tech: Head gasket

The most important things are:
* Clean the block face, head face and bolt holes thoroughly. The gasket may fail is this is not followed fastidiously
* Use a torque wrench, tighten in stages, and according to pattern

Most failure are due to not using a torque wrench or following the stages. A lot of owners just guess, and sometimes it works, but sometimes not.

I had agasket go after only a'few hundred K's and it was because the headbolds hadent been retorqued... lesson lernt

If its blown a head gasket before its overheated. The head will be warped, even more so because its alloy. You need to machine it flat and get it crack tested. Water is either getting in through the gasket or a crack in the head.

You also definately need to tourqe the head and check valve clearnces, they might not be noisy but they could be to tight and you will burn a valve.
Then you need to look at why it blew in the fist place, possibly get your radiator cleanned.

you should have torqued it up again so that there is no more expantion at all..

I wonder if your temperature gauge was working correctly? Perhaps the engine overheated.

Hi 1000Coupe

Water drips on to the air cleaner housing with Milky color oil drips also, i did not torque my head gasket after fitting it any more,and even not adjusted valve even because they are not noisy at all

Thanks

do u mean plain water or coolant with anti-corrosion? Also did u re-torque the head after about a month the last time?
