over heating !!!

[DancerEP82]

last night i when to a cruise in mk and everything was fine until i started giving it some ! we were cruising down the by pass no issuse at all water temp and oil temp was fine then i ragged from 4th to 5th hit 140mph then i slowed down and continued criusing i then noiticed my oil and water temp was getting hotter ! i just thought its becuase i ragged it for a while ? but anyway i carried on at 60mph but it was still rising but very slow but when i got off the by pass and was doing 30mph it was getting hotter until my water temp hit 100 and oil hit 95 so i stopped to let it cool down i opened the bonnet and noticed my exspansion tank was full and rad was half empty !

the thing is i bought a alloy triple core civic rad and slimline fan with fan shroud not long ago because i thought my old rad was nackered ! any ideas wot could be wrong ?

if your lucky it will be the thermostat. if your unlucky then it will be the headgasket. the fact it blew a load of coolant out and that you were thrashing the living crap out of it sounds to me like it is more that likely headgasket.

i done a compresion test the other week and they were the same reading across all 4 ! and regarding the thermostate everythings fine untill im ragging it ! but the other problem is if i criuse and all week it doenst use any water at all but until i give it some it does.....

For the sake of £13 you may as well change the thermostat. If that doesn't cure the problem then you're probably looking at a either a leaking headgasket or a cracked cylinder head.

cracked cylinder head.

I'd put my money on the head, sounds all too typical

surely the head is less likely to go than the gasket?

sounds like it is a headgasket or cracked head related problem, only happens under high load situations so wouldnt show up on a compression test. get a leakdown test done, that would be more conclusive.

as texx suggested, replace the thermostat 1st as it could be as simple as that. the longer you leave it the higher the chances of the headgasket going. after that see how she goes!

Its more lightly to be "drive like a cock syndrom".
Basically starlets have a built in fail safe, so as to prevent them from being driven by idiots at 140mph for long periods of time on public roads.
Best bet to cure it is grow the hell up and stop driving idiotic speeds that put yourself and the innocent public at risk.

I dont believe i stated it was? I just said id put my money on it being the head from previous experiences.

These are the symptoms you would receive for both the h/g failing AND the head being cracked.

the way you worded it made it sound like it was more likely to be the head cracked. i was just questioning it as i would have thought the gasket would be the weakest point rather than the head itself.

Same happened to me last year, turned out to be head gasket, head will probably need skimming too.

I was pointing out that the head cracking is a common issue causing the expansion tank to fill up and car to overheat. One thats also very easily checked. If i was meaning "more than likely" thats how i would normally have worded it

i had a simular prob whit my head it kept on blowing my intake camshaft blanking plug the 1 on left behind timing cover only new it woz cracked when i got it pressure tested

 

[wildchild]

i guess uve blown the head gasket. same thing happened on mine. temp suddenly started goin up. i started the car the next morning with the radiator cap off and noticed air bubbles comin up when at idle and more when revving. thats one way to find out if the gasket is blown.
if you continue to run with this condition, you can warp or crack the cylinder head unless it aint so already

btw check the reason first as to why the gasket went for a six. then start rectifying from there. mine had a slight leak for some time but was not much as to be a big issue. but now it is!

I'll forget you said anything !!!

Right Iv left the car for a few days and today I started her up to move it and she was miss fireing and smoking ! To me it looked like blue and White smoke so I guess its head gasket or a cracked head as mentioned but when I moved it back there was no miss firing and hardly any smoke ! So my guess is when I parked her up the other night the water system was pressurised as normal and water has forced it's way into the combustion chamber ?

Iv been thinking of going for the athena head gasket but not sure on what size ! I'm running a ct9 at 1bar with all supporting mods but in the future I'll be going TD04 maybe at 1.1 or 1.2 bar ?

Thanks guys for all your comments rep added ;-)

Bump

 

[Caineoo]

Athena 1.4mm i think is best imo. Not sure about anyone elses. How long have you run it at 1bar?

For about 5 or 6 months buddy ! The thing is would it better to keep the same compression ratios coz I'm still running a ct9 but in the future I want to go td04 I just don't want it being to laggy but if a 1.4mm would be better on the engine running the same boost I will compromise that little bit more lag.

 

[hekker]

there wont be much difrence between the stock and athena stock is 1.2mm athena is 1.4 hardly no difrence in feeling for ur ct9

Ok that's good coz I don't really like a lot of lag that's why when I go td04 I'll be getting a hybrid one but will a 1.4mm athena gasket be better for the engine running the same boost ? As a 1.2mm !
