as for hearing a water fall im not sure ima have to check and get back to that..i do hear somewhat of what can be called water splashing when it idles/sit still

I get that white smoke as well only when starting in the mornings and the rest of the day it is fine...I need to top up the resivour a bit every few weeks...I do not see coolant leaking anywhere though and I do get the burning coolant smell too.

Sorry, I couldn't resist!!

so you think this will need to be replaced?..i have no other signs of HG issues

IHateHacks · 05-03-2007, 05:59 PM

The 7M can and will run 10's of thousands of miles, some times even 100,000 miles, with a leaking head gasket with no other signs other than mysteriously disappearing coolant. No white smoke, no milkshake oil. While driving those thousands of miles with the gasket leaking, it is destroying the coolant passages in the head, corroding them and pitting them. Then, after enough has eroded away, it will start to overheat.

If you are losing coolant, but it is not dripping on the ground or dripping in the passenger compartment (heater core), you have 1 of 3 problems. Blown head gasket, cracked head or cracked cylinder/block, period. A proper running engine uses no coolant, not even after 100,000 miles, not even a drop.

well that news sucks...but let me ask you this recently i changed my rad after this I had to top up the resivour twice....do you think changing the rad had anything to do with this?...as far as the HG goes I am not sure if it was ever changed. I got this car in February.

supramacist · 05-03-2007, 11:02 PM

You're answering your own questions ebang. If you do not know and can not find out if the hg has ever been changed and you smell burning coolant....,

It hasn't been and your'e going too have to.

The damage isn't happening in your radiator, unless you are consistently overheating or dumping rad hoses.

The HG hasn't blown yet, and you have signs of fatigue. It's better to change before it goes. Or you can do like I did and say F_*k it. When it goes I'll fix it and everything I want in one fail swoop. Over 5k later I am rebuilding my car.

Right now you could probably do it smart without cutting corners for around 2k.
Butcha gotta do it before captain ahab spots her. Cause she's gonna blow. And you may want to think about carrying a can of starting fluid for when it does. That might get you home.

the last owner said he replace it with a metal headgasket (hes a machanic) but i dont believe it. so im going to ask my friends dad if he can do it for me. he has his own shop and yes i nkow i can try and do it myself buh i have no place at all to do it at. hopefully he hooks me up hes hooked me up before. and he does do really good job he rebuilt a 88turbo supra and it ran perfect

Hello credit card bill...Bye Bye life...

i think ima go with stock headgasket and new bolts..if im not modding it n e more can i just get new factory bolts and new factory HG

SAVING for a 1jzgte or a new Toyota Tundra Crewmax(i wish)

88Tsupra · 05-04-2007, 11:08 PM

well today i made a left turn at like 5mph and the light stayed on..im getting a little scared here about the HG going on me..Thanx ihatehack. ima just get the 90arp bolts and the stock gasket. because im thinking of either selling it or gettin a new motor now. I know im gunna miss the supra if i do but i gotta wait till i get a job that can afford the supra

well i have some ishino headgasket that sells for 64bux it says its OEM replacement and some felpro HG for $99
Are those good prices for headgasket and brand..i See that Hack use felpro but i dont need n ething crazy just a simply replacement thank you again guys need this help badly

IHateHacks · 05-05-2007, 02:02 AM

Yep, I used a felpro one. It was a decent quality too. It's held up to a couple hundred miles of complete torture so far

I paid $200 for a complete Felpro engine gasket set including the head gasket, even came with turbo gaskets. I just didn't use the EGR cooler gasket because it was made out of a non-metal gasket and the OEM one is metal, I bought one from the dealer it was like $20.

Light is staying on now huh? You are losing coolant quick. I'm telling ya, go buy a block test kit they are $50 and will give you solid proof if you need to start tearing the motor apart.

I overheated my car 3 times, coolant temps around 230F, when the head gasket finally gave way. I got lucky, no internal damage or warpage was done so these motors are pretty stout, but I suggest catching it before it starts to overheat. No need to take chances.

I have a brand new top line graphite hg I didn't use. It came with the kit.

Make me an offer and cover the shipping. Pics if you want.
