fuel hydrolock on ej20?
hi all
this morn i went to start my bus(ej20) and got nothing, it wouldn't even turn over.
i took the spark plugs out and fuel came splashing out under preasure so it seems it had hydro locked??
now it is showing no fault codes?
could this be just injector seals? anyone experianced something similiar?

Hmmm, in order to get enough fuel into the cylinder to hydrolock I'd think that the pump would have to be running. Are you sure it is shutting
off?
If you've hydrolocked with fuel and tried to turn the engine, check your oil. Some of that fuel might have been forced past the rings and might have
contaminated the oil.

I stripped down a rs ej20T on sunday , the same problem .The motor snaped the rear conrod and spat the oil pick up off .
they did the same thing remove the spark plug let the fuel out and hit the key .motor ran great untill the second start then bang ! dead
injector failed open ? dont think so
fuel pump stayed on ? mmmm not sure
others I have seen the air flow unit fail and fill the bore with fuel ( and put 3ltrs in the sump )
I have two ej20 n/a jap motors here & a ej25
sounds like your in more shit than the fist settlers .

fuel pump is shutting off, oil level is fine but i will change before i try and start next.
i removed the injectors today and the seals do look ordinary ,i'll get them cleaned and seals replaced tomorrow and see if that works.

Hi
With the height of the Kombi fuel tank, I wonder if you have leaking injector pintel and the fuel is able to syphon from your tank when the car is
standing. If this is a common problem a bandaid fix would be to fit a fuel lock off solenoid, but it would be best to find the cause in the 1st
place.

injector
to check if injectors are leaking you need to leave them connected tto fuel rail once lifting them out of holes, disconnect wires then prime line ,
let sit for a while then touch end of injector should be dry?? but from what you said you would see the fuel comming out ???
the seals in manifold only let air get sucked in , if worn.
not fuel.

smell the oil. if it smells like fuel, drain it and replace it before you start it.
BTW, are you sure it's not the starter motor?

sorry, I was just thinking outside the square. what I thought was a seized motor in my car turned out to be stuffed starter, that's all.
and if the oil has any fuel in it, he needs to change it or he will screw the bearings.

Steve and Ian are on the right track. Stuffed mani seals would only let air in.
Sounds like an injector is sticking and not shutting off properly. Leaving overnight the kombi tank probably would be high enough to siphon out
through the leaky injector. It would also cause fuel to constantly spray from the injector when the key is switched on (fuel pump on).
My mate parked his baja on a hill on fraser island and it let the fuel siphon from the tank, through the dellorto's, through their overflow pipe and
into his engine. We had a nice Fuel hydrolock the next day, and a couple of litres of fuel in the oil. I had to drive off to a civilised part of the
island to find oil, and then came back for an oil change in the middle of a sand island, not the best place for it

wouldn't the top seal on the injector seal aganst air and the lower seal prevent fuel bypassing the injector?
the lower seals on mine were cactus and the fuel injection specialist said that they would have been the cause.
cleaned and resealed injectors are in and it seems to be running fine with no fuel smell when i get up it anymore too.
fingers crossed

you might be right. They are quite different to my injectors.

If the engine gets just barely enough fuel in there to hydrolock it can put tremendous stress on the crank and conrod due to the angles of the
components (lots of leverage near TDC) It's likely that the engine above had this occur and damaged, but didn't break a conrod. Upon startup, the
conrod finally broke.
Now, that is a worst case. If the cylinder was half full of fuel the forces would be far lower and probably wouldn't hurt anything.
