Car steaming at start
 

Hi guys I have an issue some time ago which i'm dealing with and i'm sick of it...

I changed my engine for a rebuild one, i've bought it to Tim Benneth, i know most of you should know him..

After the engine was changed and the car started for the first time, all normal, some minor issues but the engine looks to be normal.

When we shut it down and start it again it comes a lot of white steam came out of the muffler.

So i got the car for a guy who knows about this engines, he said he tested the compression and it was ok, then he made a test umplugging the oil injectors and start the car the another day to see if the steam comes again, and it didn't so he says the problem isn't the engine, he said the problem is one of two, or the oil injectors or the mop...

So what do you think, help is really appreciate it, thanks in advance...

Have you noticed the water level in the expansion tank receding ?
Wait till the engine is warm, carefully remove the expansion tank cap and pressure test the cooling system.
Oil doesnt make steam, water does.

there's 4 oil injectors and they rarely fail in a manner that cause oil to leak into the chambers while sitting.

thick white smoke is usually coolant getting into the engine after the metals contract. oil burning will have a light blue tint to the smoke.

I know is oil what is burning because i'm spending a lot of money in oil, as suddenly the oil red light comes on, and then the car heats a lot when it has a lack of oil...

I don't notice anything blue in the smoke it triggers, is white, and the coolant tank is filled, CRO8TIA i'll make that test, but what do you think ?

But hey, what about the test the mechanic did, removing the injectors and wait the car cool down and then start it to see if the steam appeared and it didn't ..

I think you have bigger problems if this statement is true

Edit:
To clarify, if you have a lack of oil, the bearings overheat and sieze the engine really quickly. If low oil is causing your COOLANT to overheat, then you have something seriously wrong somewhere.

Yes, i know, but taking in consideration the tests in compression, and removing the oil injectors, can we say is not the engine what is wrong ? can it be the mop ?

The oil system is part of the cooling of the engine, and coolant tempts tend to mirror oil temps. If you get low oil to the point that oil is no longer supporting the heat management, that means that there isn't any oil flow through the engine (either there is no oil there at all, or there is oil in the engine and it's blocked up there) OR there isn't any oil flow through the oil coolers. This would be a really big problem that would be terminal for the engine.

I'm hoping that there is a language barrier that I'm just not understanding you well.

compression results will usually not reflect an internal coolant leak, unless the leak is extreme or has gone on long enough to cause internal damage to the sealing components inside the engine.

your mechanic needs to do more thorough testing than just disconnecting the oil metering nozzles.

The thing is, I'm so frustrated, I mean I bought this engine as I had troubles with my last engine because it has some compression issues and it was triggering to the radiator and car heats a lot.

So some mechanic recommended to buy another engine, I made a question to this forum and some of you guys told me to buy a new one, which was ok..

The thing is, I have this weird issue that points it could be the engine which is broken, and I don't have any more money to buy another engine...

So, i'll keep dealing with this and i let you know how it goes..

Your cause and effect seems very disjointed and not really connected. A compression failure in the engine won't cause a coolant overheating condition. However, a coolant overheating condition CAN cause an engine to fail. Did you overheat the car before? If you replaced the engine but not the reason for the cooling system failure, then you are just going to lose this engine too.

I mean we're talking about different scenarios here:

1) the old engine has an issue with compression, it has like an open seal, putting some hot air into the radiator or in the cooling system and that's why the engine was overheating the car

but this is not a matter now as i bought the new engine, so talking about this is lame as that engine is not on my car anymore

2) new engine case: first engine was burning oil, i know because when i start the car, a white steam (a lot of it) comes out from the muffler and then the after some miles (not much) oil light turned on and i have to put a quarter of oil every two or three days

i get the car to the mechanic and made some tests: a compression test, which passed ok, then the oil injectors removing tests to see if the cause os burning the oil comes from the engine which is not, because when he disconnected the injectors it was no steam...

so he thought there is two possibilities there, or oil injectors or the mop

after he gave me the car, a couple of days ago, it results the car begun to over heating a lot (before this, car overheats more than regular but not as much to complain, mechanic said we had to take care of that after fix the oil problem) and i found that i put coolant on the tank and after some minutes of driving and car over heated i checked coolant tank and it was empty, so i took it to the mechanic to see what is going on now with this new problem, when i checked oil it seemed ok like if there is no burning or the burning is less...

1st problem) That sounds very much like a cooling system failure that blew a coolant seal in the engine, which was then pushing combustion gasses into the cooling system. This wouldn't be causing the car to overheat however, the overheating is already underway from other sources, it's just another result from overheating.

2nd problem) A lot of white steam coming from the exhaust suggests coolant burn off, which suggests that you still haven't fixed the cooling system failure that caused the first engine's failure, and it has now killed this engine too. Overheating the engine can easily warp the housings, which will also result in oil control ring failure a significant oil burn. Oil burn won't be white smoke though, it will be a blue/gray smoke.

Remember after i put the new engine, i didn't have a coolant problem, it was certainly an oil burn problem as the oil was getting less and less, with no coolant diminution, the coolant thing was 2 days ago...

Ok. Just trying to work through the language barrier here, I don't have the car in front of me to go off of anything but what I understand you to tell us.

And i really appreciate that dude, thank you... i'm just affraid this engine is not working, i hope it is something else my mechanic could fix...

Sick of this problem !!!!
 

Hi guys, i'm so freaking sick of my problem...

First I bought a rebuild engine from Tim Benneth, after the engine was changed, the first test looked ok, then we shut off the car and start again and then this white steam came out...

Car had a temperature problem, it was fixed, i had to bought a new radiator, temperature is fine now..

But i still have the steam problem coming out from the tailpipe, I've seen videos in YouTube related to steam issues with rx8 but my problem is not the same, all videos i have seen are cars steaming constantly, mine only steams like 30 secs or 1 minute after i turn on the car, if i turn off and turn again it steam again, is like every time i turn off and on steam comes...

Compression tests went fine, temperature is fine...I'm so sick of this, i just want to sell this car but nobody will buy a car like this, I'm desperate, I've invested so much money with no results....

If the motor was overheated, there is a good chance a coolant seal let go. Pressure test the coolant system first and see what you find.

Then i should have a lack of coolant right ?

I have just checked the coolant level and is fine, i checked oil level looks fine, what i think is too liquid but no sure about it, tomorrow i'll change oil such as the filter, and let the guys tell me if the oil is weird...

one interesting thing is that every time i put new oil (mineral 10w30) steaming is less...

Are you having to add coolant?

No, coolant level is fine, it's not getting less...

I think you should put up a video of what you're experiencing. This could just be a result of condensation accumulating in your exhaust after cooling down. Do you live in a humid environment? Are you sure it's steam a opposed to smoke? Do you add premix or Seafoam? Do you always use the same gas station? There are only so many fluids that can come from your exhaust.

This morning i took a video but it didn't steam too much, i got my car to oil change, and changed spark plugs and see how back cylinder spark plugs see...

Damn! Those are fouled as hell. Replace them as well as the coils and wires.
