heya guys,

dunno how to say this im so ****** pissed off right now

basically i just got the car all running, every now and then the car is smoking hardcore ( white, coolant )

i just basically came back from driving the car on the way back to my house
when i pop the hood up, i could hear like a water gets boiled and theres water dripping on the side of the block, right where the headgasket is .....

what i dont understand is everything on my engine has been built according to specs, the engine just been used for like 150km no thrashing what so ever since
the rev limiter sets at 4000rpm

the block has been o-ringed with copper headgasket

please guys i really dont wanna take the head off again ......

if you let the car idle with the rad cap off dose the coolant bubble over? and how much coolant did you lose after the 150km? it could be you just didnt bleed the coolant good.

You may be able to re-torque the copper head gasket. They are normally annealed (heated to 350 - 400 degrees and cooled slowly by turning oven off and leaving the gasket in it) to soften them prior to install to soften them so they can conform. They aren't ideal for street applications, normally for race motors where they are re-torqued regularly.

ive never heard of anyone having success with a copper HG.

check the coolant to see if its mixed with oil. it will be thick and milky

do a compression test, or even better yet a leakdown if you can.

and like someone mentioned, you can try to retorque.

damn I feel for you man, do as suggested above and don't get discouraged, screw it if you have to pull the head again it's just more practice and you'll just be able to do it quicker. if you pull the head I would get an OEM gasket...

make sure it's not your intake gasket. thats one way to get coolant into the cylinders and also leak down the side of the block making it appear to be comming from the HG. I've had many leaks from hoses ect, and It makes its way around the HG area to where I could have swarn it was the HG but it wasn't.

heya guys thank you so much for the info,

heres a lil more informations i forgot to mentioned on my 1st post

the car basically just overheating every now and then, its not all the time
sometimes i can drive it for 30mins without overheating but sometimes out of nowhere the car just burns heaps of coolant and it stops by itself .....

I've just checked the oil, its fine its NOT milky and stuff

I will go for a drive soon and check the radiator water

and the reason i went with copped HG is because i got the block o-ringed and the engine rebuilder suggested that i should go with copper cuz it will sealed better

do you guys think the engine internals still alright ?? after its been overheated a couple of times ???

thanks

does it usually overheat or comsume coolant after you have been boosting?

also, do you have arp head studs? and if so what are they tq'ed at?

i would first figure out exactly where the coolant is leaking from. Maybe try and get some good pics if you can. There lots of things that can leak and drip to make it seem its coming from the HG.

If everything checks out there, i would do a leakdown test. That should isolate the problem and tell you exactly what is going on. If not a leakdown at least a compression test.

and if you do end up having to pull the head, i really would suggest using copper wire for o-rings and an OEM headgasket coated with copper spray.

hey

no i havent been boosting the car at all, the rev limit is set at 4000rpm by my tuner

yes i do have arp headstuds, i have no idea how much they torqued ( engine builder )

I just went for a drive before like 20 mins, it wasnt overheating and theres no oil in the radiator and engine oil is free from coolant

so im confused as expletive now

gritsak

is the coolant still leaking?

if it wasnt for the fact that you saw the coolant leaking then i would say it could be air in the cooling system.

Copper headgasket sucks for cars that are daily driven. The gasket may seal very well at first, but after a couple of heat cycles, it needs to be retorqued.

Also, is your block sleeved? I've seen several cases that a bad sleeve job (sleeve sinking) will cause situation like yours. So if you car overheats like that, you should pull the head and check the straightness of the head as well as the sleeves by a machinist.

yes the block as darton solid sleeves, machined by reputable engine rebuilder in my country and i gave him the specs i got from Darton

I really hope its not the sleeves sunk

he might even have a blown head gasket, when i had my motor built, after 2500 miles i just blew a headgasket out of no where. yes i had arp and torque them down to spec and i used an oem gasket. there was no coolant with oil, and no oil mix with coolant. and it didn't even overheat, it just consumed some coolant. so i changed the gasket out and im at 6k miles and still running strong. but hey, just sharing my experience

Cyber ITR

im expecting the worse already, sunken sleeves .......
