    Hei, I've got an escort that was running just fine except that it was weaker that it should be, but when driveing the other day it started making a hissing noice (if I describe it correctly, sound like escaping air) and the engine started stalling at idle rpm. I could still drive it, but the powerloss is now even greater and it doesnt run on idle. After parking it in the garage to start debuging I noticed smoke in the engine room. The sound is louder than then engine and it gets louder with higher rpms.
    Any idea what could be wrong anyone?
    Thanks.

    Check the air inlet hose, paying close attention to the ribbed section. That hose is known to crack there. If that hose isn't leaking, start checking all the vacuum hoses for leaks.
    Another valuable tool to use is the red search button on the top of every page.
    Good Luck

    Have you ever replaced the timing belt?...........It could have jumped time my zx2 lost power and would make a growling sound in the higer rpm's and teeth were gone off the timing belt and it jump a few deg.

    Try checking to see if the catalytic converter is plugged up.

    Thanks for the replies. I was thinking the inlet air too, but the leaking smoke made me think maybe there was somthing very somewhere else. I dont have much experience with those electronic injection engines so I'm not shure what can cause a powerloss. I'll start with inspecting the inlet then.

    I figured I check the headgasket, but I was unable to remove the head due to some stubborn bolts. The trox keys just snapped in two leaving half the key jammed inside the bolt, so now I'm stuck. I guess I have to look for a new engine if I'm not sucsessfull with drilling the things out.

    The car I have is a european '95 Escort CLX 16V AAL 1.6i model V. Does any of you know what engines would fit without much modification?
    Thanks

    Re: Power loss, then sime hissing noise.

    Sounds to me like you have a major vacuum leak. Have you checked the PCV system to see

    if the oil leak is coming from it?

    Hope you have checked akk the simple things before tearing the head off. I haven't seen too many head gaskets that have caused an external oil leak, nor a loud 'hissing' sound like that of escaping air as you describe.

    Good luck and let us know what you find.

    Drive safe,

    Never said anything about an oil leak. There is no oil leak, just smoke.

    I must have misunderstood what you meant when you said you saw smoke in the engine room. I took it to mean that when you had the hood open, looking under the hood, or 'in the engine room' you saw smoke. That would normally come from an oil leak and the oil burning on the exhaust manifold, or from excessive blow-by, and the smoke coming out through a hole in the PCV hose, which could be where a vacuum leak might be.

    If by the 'engine room' you meant the garage, and the smoke was coming out the tail pipe, then it could be valve seals or rings. What color was the smoke? Black is fuel, blue is oil, white is coolant.

    What did you mean when you said 'engine room'? The garage? The engine compartment? I hope that if you meant in the garage, you had the door open, and the exhaust pointed out the door.

    I am sorry about misunderstanding what you said.

    Good luck and let us know what you find.

    If you are hearing a loud 'hissing' noise, then I would be looking for a vacuum leak. If it gets louder than the engine, I would be looking at all the gaskets that seal the intake. Maybe start by checking that all the bolts are tight.
    Some people I know have used ether (starting fluid) to find vacuum leaks. I prefer to use WD-40. With the engine running, slowly spray the WD-40 at all the places where the intake bolts together. When the idle changes, you have found your leaking gasket.
    The smoke you seen was probably coming off the motor bacause it was getting hot due to the fuel mixture being too lean. The temp. gauge might show normal, but the exhaust will be hotter running lean.

    Hello, I've had similar problems with my car. I don't have the Euro Escort (regular EGT) but this sounds a bit similar to what I'm going through.

    I've heard that the BP motors are really sensitive to vacuum so I figured that might explain why I've been really low on power. The car was fine before and during the last race that I had in November. I only drove it once between then and the new year and since the new year I've barely been able to get onto the highway and once there it will barely hold 65. Anyway, I'd like to figure this out because my next race is next week and I'd rather get to a blown head gasket sooner rather than later if it comes to that.

    From your description above, it sounds like you have a blocked cat, or maybe a collapsed exhaust pipe. Why not disconnect the cat (at the front of the cat) and drive the car to see if it has more power. A vacuum leak shouldn't keep it from getting to highway speeds. Sounds more like a blocked exhaust or cat. That will also make a hissing sound.

    Good luck in the race,

    I have a buddy with a egt, about 2 weeks ago me and him replaced his intake mainafold, after we got it all together and started the car a loud hissing noise accured and a bit of smoke from under the hood. After checking eveything we could think of it ended up being one of his fuel injector seals went and was the cause of the sound and smoke, just replaced the injector with a new seal and problem solved, don't know if this info will help or not but it worth checking.

    Thanks. That might be the problem. I haven't worked on my engine in a while now, but I'm starting with it again now. I think I might just swap out the whole head with the intake manifoil and injectors and everything, should be an easy fix, I hope.

    What I've found out so far is that one of the intake valves leaks alitle. I though that it might be part of the problems. What realy concerns me now is that I found small peices of metal shavings in the sylinder. It doesn't look like it has damaged the sylinder walls, but I would realy like to know where it comes from.

    I've got the head off the engine now btw in case that wasn't clear (as I had problems with that earlier).

    didn't you say you had to drill out the broken torx key? If so that may be the source of the shavings.
