Well people, today has sucked beyond believe. I'm on the side of a freeway off ramp where my Subaru 2.2 stopped running. Shifted out of gear and it cut off. Looked in the back and it was smoking a lot. Opened the trunk/hood and lots of steam and no coolant in the overflow.
Found out I blew a hose and was running it dry. My sensors are not working at the moment. The engine will crank, but not catch. How much damage have I done?

you say it's able to crank so that is a good thing, considering that it could easily not crank.
What happened to your sensors? why were you running without them?
Water under the bridge or out the blown hose...
Do an oil sample analysis and see how much metal content it shows.
Considering your hoses were old enough to blow how many miles on the engine?
Change out the old burnt oil with fresh and do a compression check and cross your finger while saving for getting it rebuilt if you compression is low.
Really though, any answer to how much damage you did is a guess, an educated guess if the guesser has long time experience, but a guess none the less.
Good luck. |

Depends on how long you were running it dry.
Better than a compression test would be a warm oil pressure test at various rpms.
The suby 2.2 is an amazingly tough little engine though. ...

Well that sucks. Let it cool down, put some water in it, and see if it will start. Good luck.

Yeah it would be a much better test! It's probably the one I was thinking of!  Doesn't sound like he has any readings from anything. |

Agree, don't give up on the engine. They are tougher than people realize. The stopping was probably due to the sudden heat buildup when your engine revs dropped and either:
Something electric (wire, sensor) suddenly melted and shorted.
The fuel line flow slowed and it is vapor locked (rare on efi but extreme cases)
The valves were close to sticking and the extra BTUs caused them to sieze in the valve bushings enough the compression dropped and combustion too.
Learn on the Blackstone Labs website how to get an accurate oil sample while you are changing the oil (mandatory). Then refill water and oil. Do some checks on electricals that may have melted. Pull the spark plugs and look at/replace. If its like the WBX, can you pull the valve covers and verify the valve stems all line up correctly? Then try to fire it up.
Anyone know if this is an interference engine? Seems to me the 2.5 is, but the venerable bulletproof 2.2 is not.

| I'm curious why the gauges weren't working. Did they fail on the trip and continuing driving was your only option? Were they not working before setting out but the trip was an absolute emergency? If the answer is no to both of those questions, then you really asked for the pain. |

| Worst case you will have to dobhead gaskets or a rebuild... Both are reasonable in price and parts are easy to come by, so it goes. |

Tough little engines. But from what I have heard, they don't like to be overheated. You might get lucky!
I had a clamp blow off the radiator hose. Instantly my light was blinking at the loss of coolant. Engine got shut down immediately then on to the shoulder of the freeway. I was lucky and caught it quickly.
Now I have an additional set of gauges so I can watch the water temps, engine oil temps.
Hopefully you dodged a bullet.

Fingers crossed for you.
My 98 Legacy 2.5 had a slow leak in the radiator. It went from normal (on the temp gauge) to critical (pegged) in a couple miles on the way home from work Like you, rad was dry and lots of steam. I let it cool down, was able to refill with water and get it home. A new radiator and it's been trouble free since.
Hopefully you caught it in time.

For those wondering, no I don't have the temp gauge working at the moment. Yes I know that's not good.
Well I replaced the house that broke and thought it broke because something hit it. Large deep scrapes and then the hole, but then I found out it was a little more complicated than that. After replacing the hose and draining all liquids, I thought I was good to go.. Took it on a test drive and one of the front radiator hoses blew. Coolant all over the van.
I gave up and its been towed to a local shop for the painful discovery process of the failure and the bill.

Hang in there, it could be worse. You could be posting on the Yugo forums  |

whow, that is a really bad place for a hose that is so critical. Id make a shield to protect it.
Maybe get a differently bent hose, maybe it can be angled up as soon as it exits the engine rather than have that long horizontal run near the engine mounting bar????
as far as the radiator hose up front, well I guess it was just time, and that tells me that maybe all the hoses are old and might need replacement before failure.
I did all of my hoses, although non had failed, 30 years is long enough for a hose if you want dependability. I even replaced my radiator, not cause it failed, just cause I didn't want it to fail later.

Burley motorsports sells a stainless steel pipe that would replace that rubber hose that has been bombproof on my vans. IMHO a rubber hose there is just a problem waiting to happen.
Good luck. |

I have a feeling the water pump died and the system is over heating and over pressurizing. Just my uneducated guess. The whole system is only four years old. All the hoses and radiator where replaced then.
I don't know, just hope I didn't kill the 2.2. If I did, it's time to find a Yugo forum and a new fake name like Speedy Yugo Mc fastie.

Blowing a second hose quickly would indicate the system is certainly being over pressurized. You may have two problems. One the cooling system pressure cap may not be releasing pressure as designed. Second, the cooling system is getting over pressurized because cylinder pressure is getting forced into the cooling system.
Since the temp gauge was inop, the engine could have been running hot for quite a long time. You don't mention how long you ran it without a gauge. Either way bummer. |
