I already did a search...
I have a 91 na. I had a coolant leak coming from somewhere (not the upper/lower/heater hoses, or the water pump). When I sat with the car idling my idle would bounce from 1 rpm to around 900. I probably just needed a tune up though, but my car would overheat up to the H. When driving it would go back down. One day It started smoking under the hood. The thermestat housing cracked open spraying coolant everywhere on the intake hose and throttle body. I drove the car for a couple hours to get home. It was overheated past the H. I had smoke coming out the exhaust and even the shifter inside the car. I made it home with no wierd noises. I can still start the car and it sounds strong. Only problem is it idles at around 2500-3000 and overheats. I replaced the thermestat and housing. When I poured water in through the radiator it would pour out in like 5 spots under the car. A few days later I poured water into the radiator, waterpump, and the upper radiator hose without the thermestat and housing being on and nothing leaked out. Now there is just a huge oil spill running from the engine to the back of the car. Can anyone explain what the hell could have happened? I know this was long, but it's better to be descriptive so you guys don't have to ask me questions like what kind of car do I have. Thanks

Well, first off... Overheating it past the "H" has probably done your waterseals in. In fact, I would be suprised if it didnt. That would explain your overheating.

Here is a test:

Fill up the whole cooling system (engine cold). Pull your EGI fuse (underhood). Crank the car. If coolant comes rocketing out of the coolant neck, or your coolant smells like gas, you have nuked the motor.

NEVER drive an FC when the temps are at the "H"

I guess my water seals are out then... Could I also have killed my oil seals and thats why there is so much oil under my car? There is a lot of blue smoke that comes out during warm up. My car still holds water and runs great though. I understand blown waterseals mean rebuild but what exactly does it do to the car. I havent taken it out for long yet.

 

You need to figure out where the hell the oils coming from. You could've burnt up the oil seals, and that'd dump a massload of oil into your exhaust, but anyway. Find your leaks, repair them, and try again.

 

Just wondering but couldnt you have called a tow truck to bring tow it home instead of driving it for a few hours while overheating? I think by taking this precaution you could have saved the engine... maybe.

 

I could of but I didnt care anymore. I wanted a new engine anyway, but now im not ready financially yet so im kinda screwed. Since I blew the water seals will my car always overheat or will it still hold a safe temp. What happens.

 

you should probably stick to public transportation if that's all the care you put in your vehicles. decent cars aren't cheap and neither is replacing engines cuz "I didn't care". If you knew you wern't ready to rebuild or replace the engine, why would you do such a thing?

 

Kevin at rotary ressurection could probably get a motor out to you for about a grand, probably a few hundred more since your core isnt worth dick all anymore.

 

You did WHAT?????

No offense man, but if that is the kind of care you give your car no wonder you have problems.

Anyhow, do the test as mentioned above and if in the unlikely event you don't get a geyser, have itTOWED to a shop and have them do a pressure test on the coolant system to find the leaks. The blue smoke means you probably fried the oil seals too....

 

Is this your first car? Anyone who can see coloant spewing out somewhere would have called a tow truck but not drive for a couple hours. Frick, even my mom knows not to do THAT!
A small problem ended up with a blown motor. That's so sad. It would have cost you a used thermostat housing that's maybe $5.00 and ended up to at least $1000. I highly doubt most parts are usable for a rebuild since the housings are warped to hell from over-over-overheating. The reason you're getting multiple leaks everythere is because you warped the housings. You posting on this forum and telling us you drove for a couple hours with no coolant deserve to be treated as such. You're not getting sympathy from me. That is just total stupidity.

 

If Kevin reads this, he's not going to sell him a motor.

 

Thats what I was kind of thinking! But money is money.. Never know, this guy might turn out to be a great customer


Honestly, you are worse than my friends mom who thought she could leave her oil in for 50 000km. It was white sludge when the motor went.

 

I'm not asking for any "sympathy", and we all know it was stupid thing to do, but at the time i was ready for a new engine and now im not. **** happens. I started this thread for help. Thanks to J-Rat and SonicRat for the help. That's what these threads are for. Not pointlessly talking ****. If you want to talk **** then at least answer a question. Dont waste my time and everyone elses who might need to know this info too by saying stupid **** like "you are worse than my friends mom."

Can someone helpful please tell me why the motor is shot when the waterseals are blown. There are no leaks as i pour water in. Will my engine hold a drivable temp. Thanks

 

There is about a .0001% chance you didnt warp the housings and irons. And no it wont hold a drivable temperature. Youll probably have coolant leaking into the combustion chamber. Go have the cooling system pressure tested. Not to mention you said your car wont hold oil.

 

thanks
