coolant issue!!!!

[crossbreed]

I have a 92 tsi and just out of the blue, i have a cooling issue. my upper hose keeps blowing up like a balloon but don't over heat till it pumps my coolant out of the over flow bottle. i changed my thermostat twice since then and that makes no difference. do you think i have the wrong coolant mixure.

[xxxfrankenstein406xxx]

sounds like somethings blocked. what does the sensor read?

[all_rice]

I would be willing to bet its the head gasket pumping pressure into your cooling system.

[all_rice]

the head gasket being blown that is. they make a thing to test your coolant to see if your getting exhuast gas into the cooling system...I would have that done.

the temp reads great until i get the rpms up then it will pump the coolant out as fast as it spools.

so when you gonna come help change the head gasket. it's just a little odd that it could be bad since its only a 4 month old motor.

[crossbreed]

will a weak upper radiator hose cause high coolant pressure

[Integra 26R]

Did you try pressure testing your cap? And yes you have a bad hose if it blows up like that.

he tried pressure testing his cap. i believe he bought a new one too.

[Integra 26R]

Well the cap should have opened at the set psi. Pressure test the system and replace hoses that expand. And check that the fitting and line to the overflow aren't clogged.

Ill come help you change it right after I get done doing mine I got stuck with the laser the other night apparently both rear wheels arent spinning :mad:even tho its an lsd....so that needs to be fix and I guess the fan wasnt kicking on at we were stuck on the lake bottom line it overheated I either blew my head gasket,warped my head,or my bolts stretched and my head lifted...compression is low on all cylinders but when it was running it was smoking and there is no oil in the coolant or vise versa.

Sounds like you fried your rings.

[crossbreed]

great news. i have exhaust smell in my coolant. smells like a blown head gasket.

[all_rice]

I doubt I fried my rings....pretty sure its the headgasket. my laser sat for 7 years I cant imagine the headgasket was too good to begin with. and yeah im pretty sure you blew yours too crossbreed.

[northsydryd]

i have a head that im not gonna use.it needs valves and 1 of the spark plug holes chased with a tap but its straight/flat.6bolt turbo head,let me know if either of you want it...
crossbreed,r you talkin about the same engine you got from nick? that didnt last long at all

yeah he's talkin about that block. But i'm pretty sure it has to do with the head gasket or the head might be warped.

That would mean it would have no compression or be burning coolant.

[northsydryd]

i know it would be a head issue... mabe you didnt get the surface clean enough when you slapped the head on it?if i remember right it had some surface rust on it...or mabe the head was warped to begin with and it just happened to last this long? who knows

[stageberg]

pretty sure he just had a bad gasket the head was milled and everything by the looks of the old gasket it makes me think the gasket failed but i guess we will see!!

[stageberg]

just cuz u have a lsd doesnt mean both rear wheels will spin if u had posi it does lsd just means u have a good chance of both wheels spinning pretty much

[Integra 26R]

Posi is lsd. Its just a fancy marketing word.

[stageberg]

well then if u have a locked or locker rear both wheels will spin

[all_rice]

so I said in the original post it was smoking but I meant to say its not smoking just realized that now I tested my rings with oil and a compression tester they are fine my headgasket not so much water was coming out of the cylinders with the oil. O well shit happens I drive a DSM I wouldnt expect anything less...plus it was pretty much my fault.

[all_rice]

not to steal your post but as far as my rear end not locking. from what I have heard thats a viscus coupler rearend. I just changed the fluid in it that night and I totally spaced out to see if there was an additive I needed and do you think there could be not enough fluid It wasnt completely full defenately enough to not hurt anything but I understand the viscous coupler using the oil to work so I was thinking if I didnt have enough or maybe It just got too hott from spinning in the snow?

viscous work by fluid heating.

[all_rice]

hmmm how do I fix this...and please dont say buy a new rear end lol i looked at the prices not real familiar with awd's just fwd.

[all_rice]

oh and fyi integra it cant burn coolant if its dumping to much coolant in the cylinder to start and loosing compression through the coolant passages....but hey what do I know.

[xxxfrankenstein406xxx]

whats wrong with it? I have a 3 bolt lsd

[all_rice]

only my right two wheels were spinning so I dont see how my viscous couple can be working correctly....my car is a 92 6/4 combo it clearly says its a lsd rear end on the door just. I want at least 3 wheels spinning at all times.

it will only do it to wheels with traction tho.

They do wear out over time. Or somebody swapped it with a non lsd.

I am an auto tech I do know this stuff.

[all_rice]

well you made it seem like you were the only one one the planet that knows how to fix anything....

[all_rice]

not trying to argue with you I know your trying to help I just know its my headgasket i am in no means a newb you just dont hear from me alot on here.

[all_rice]

and like I said I know very little as far as the rear end's in awd I just know how to make a fast fwd's.

[viprez586]

I didn't quite understand that comment either.:rolleyes:

In the event of a blown headgasket/cracked waterjacket. When coolant is entering the combustion chamber - some of it will vaporize, liquid coolant and vaporized coolant will exit the exhaust valve. Some of the combustion chamber pressure will "push" coolant hence your big radiator hose.

It's not like taking water and pouring it on a fire. This is a rapid, controlled, precise mini explosion taking place.

[all_rice]

couldnt tell you...im not an auto tech :rolleyes:

[Integra 26R]

Except for the fact that in a normal working cooling system the cap keeps it under pressure to a preset psi. So regardless of a blown headgasket, the system will build pressure anyways and the hoses should not be expanding. So no a bulging hose is not a sign of a blown headgasket. Its a sign that the hose has deteriorated and needs to be replaced.

As for the auto tech comment, I'm saying I know what I am doing. Its what I went to school for and its what I do for a living. Most of the people on here do it has a hobby. No, I am not the only person on the planet who knows how to fix anything but I have fixed more of other peoples fuck ups on these cars then I know what to do with.

[northsydryd]

even if the head gasket is blown that hose will need to be replaced.when it expanded it broke all the bands and thats why its swelling so easily now

My comment before was directed towards rice.

I neither was implying a blown headgasket would be the prime reason to expand a radiator hose - obviously the hose is weak - I thought that would be assumed. At the same point yes if the hose is that weak and deteriorated the mid-teens(of psi) of cooling system pressure could expand the hose - no doubt. Add cylinder pressure into the equation and I would not doubt a newer hose would too expand - perhaps not as drastically. Your talking about the difference between maybe cooling system pressure ~ 15psi to cylinder pressure which could be anywhere from 60~180psi depending on the exact condition. Unless this hose indeed has the wall thickness of a balloon - 15psi will easily make it look like one.

Me and you both buddy, we work on cars for a living but I don't provide that personal information to assist people with their problems on their cars. I'm on forums to: help people, gain tid-bits of knowledge, expand some insight on little issues I have with my personal cars. I'm not being a smart-ass but sometimes I guess people read into what I say a little too deeply.

[all_rice]

so figured it out...wasnt the rings it was a blown head gasket and a incredibly warped head. The machine shop said it was warped twice what they could mill it....might have got a little hot :rolleyes:

[viprez586]

.008 is the limit for warp.
Mine was warped .010, cam journals were scored. Hey nice paper weight though.

Who'd you take it to?(Extremely late post anyway)
