Hi,

I just finished body works on my leone, ill upload the pics soon.

I have an Ej20g running in it.

My friend interchanged the fuel pipe by mistake, the engine would not start I corrected the piping, the engine started. (I’m using a Bosch fuel pump)

I went for a test drive when I got back the car started missing and went off.
When I tried starting it, the engine would not rotate, I removed the intercooler and fuel was coming out, the exhaust pipe had alot of fuel coming out too.

I checked the timing it was ok, I removed the plugs the 4th cylinder had fuel inside I rotated the motor it was fine, a lot of fuel came out.

What is the reason for this? Is there any damage that can be done if the pipes are interchanged?

Why would this happen?

Thanks,

Regards,

Amk.

I wonder if any damage was done. Or just gave fuel another path to flow? The vacuum line to the fuel pressure regulator on the fuel rail , does it feed to the inlet manifold near the inlet of cylinder with the fuel in it? Is it running OK now that you have swapped lines back to correct pipes and removed fuel, dried off sparked plug?

Well it turned out to be the seals for the injector were broken so I replaced them. Now I have another problem the intercooler got filled with engine oil, why would this happen?

If you have excessive crank case pressure oil is forced past the seal in the turbo filling the intercooler

Mabye just be that the motor has been on its side or inverted for some reason or turbo has seen better days.

New turbos eg TD05 16g can be had in aust for around $400 landed from the US

If it had been inverted or on its side and filled the combustion chambers with oil it would either hydraulic or pump it out the exhaust valves and smoke. but yeah a stuffed turbo will do it also, i was just saying maybe check for blow by before condemning the turbo.

well if the combustion chamber was full of fuel then it would have to go somewhere hence filling up the crankcase and giving it excessive pressure.

What does that even mean?

blah, blah, blah, BANG, blah, blah, blah...

but seriously it means that major damage can be done inside the engine if too much fuel is injected

How is that relevant to oil in the intercooler?

I have no idea what it has to do with the "oil in the intercooler" ?? as you can see from the above quotes, I was (and from your replys) was referring to the excess fuel in the engine.

BTW.. Oil in the intercooler/intake system comes from blow by. When oil gets too hot it vapourizes and is sucked in by the intake manifold vacuum via the breather pipes.

Hope this helps?

or you can have to much crankcase pressure as a result of cracked rings etc causing the oil to push past the seal in the turbo filling the intercooler very quickly with oil
