I've been in denial for the last month about my Geo Metro having a blown head gasket. One day it got really hot on the freeway (100+ outside, a/c full blast). I pulled over well before it maxed out & let it cool down. It had puked out coolant from the over flow so I added some water & limped home. Since then, every time I drive it on the freeway, it will puke all it's coolant out the overflow. I did a compression test, all 3 are fine. Spark plugs look fine. Flushed radiator, flows fine, fins fine. No white exhaust smoke, no chugging, just bubbles in the coolant. I have even flushed the cooling system & changed the coolant twice. With new coolant it's much more stable, but as soon as the thermostat opens, the coolant bubbles in the radiator & finally boils over. All I can think of is that there's a pinhole in the head gasket which is pushing compressed air from a cylinder into a coolant passage.

On the bright side, while I'll be wrenching away on it in the garage, I will be jamming to internet tunes on my new garage computer. I just need to build a wifi antenna....

 

Only time Iv ever rolled in a Geo....... I was hammered drunk.

 

^^^ hammered on Coke? Buahhahahaha!!!

Yeah, the Geo is only for work commuting (~60mi/day). At 50mpg, and gas at $2.50+ I don't want to lose it.

 

Is that kid doing the Guido pout thing with his mouth?

Skib you have weird friends.









...and you're a bro!!!

 

Have you tried replacing the radiator cap? Our jimmy would constantly just boil over the coolant whenever we drove it on a hot day... but it wouldn't over heat. We replaced the coolant cap and walla! I guess it wasn't holding the pressure which helps raise the boiling temperature.

 

Yeah, forgot to mention that. That was the first thing I suspected. Replaced w/ a 15lb heavy duty cap & it still does it.

 

Low oil maybe? That seems to be a common culprit for overheating with these miracles of engineering. Why not see what the pros think . . .

RX-7 oil cooler and Fiero radiator!

 

I had a metro race me in my Z the other day lol I was going 90 in a 35, it could even try to keep up, and they started the race! I think they where drunk XD

 

lol, time for that b20 vtec swap!

 

That is retarded. Plain and simple. I would have called the cops on you if I saw you doing that crap near my neighborhood.

 

Hey its a 2 mile perfectly straight shot on a brand new flat road so *shrugs* Its not like I do that everyday

And I'll agree now looking back at it, that was VERY stupid. lol

 

its not like its difficult to work on, quit yer bitchin and pull that motor.

just out of curisoity could you weigh the motor? i always wondered how much a 3 cyl weighed in one of those, i dont think its light, i hear they have cylinder walls like the great wall of china

 

relax he was only doing 90, its not like thats fast.

 

Ya I could have gone faster but I was already beating down that metro pretty badly. So why go faster then you have to huh? lol

 

Why even race a Metro?

 

yeah dude!! yesterday i saw a seven year old an i arm wrestled him but after i won i just beat the **** out of him for fun!!

 

I didnt even start it.

dummkopf

 

ever been stuck with a really obnoxious 8yr old? but you think you cant hit him cuz hes 8.
just lay that little **** out with a right hook.

its the same level of satisfaction as beating a metro in a race


but its all cool, your not a ***** for beating up kids, he started it

 

 

lol, the caption of that picture should be: "you wanna suck my dick man?"


and enough thread hijacking, nismo just change the HG, god knows you probably dont even have to torque the head down.

 

The super crappy thing is the head bolts are "stretch bolts" and must be replaced after the first use. I actually planned on reusing them anyway, but after reading the procedure on teamswift.net, it's just better to do it right. I ordered a complete gasket & head bolt kit online for $34 (just the freaking headgasket at Napa is $29) and it should be here by the weekend.

3cyl FTW!

 

It'd only be easier if it was a OHV engine....

 

could you fit some ARP hardware on that motor?

 

and boost it
