gas for oil

[purg113]

well somehow my fuel pump stayed on lastnight after my wife drove it and now it has gas in the oil can I drain it and flush it with somthing then refill it with oil?
or do i need to tare the engine down and rebuild it.

89 f350 w 460.

as long as it wasnt run for long you can just drain it and refill it, if anything it might have helped clean some gunk out of it if it was started,

yep just change the oil and enjoy.

the good thing was I never started it

Pull the vac. hose off of the fuel pressure regulator and check for fuel in it. Very common for the regulator to fail this way.

In that case.......





You're golden Just change the oil...

Sounds like a good low temp fuel additive: Burn it in your IDI

 

[Matrix37495]

6-7 GALLONS? Was it running out of the intake?

It wouldnt have started anyway, it would be hydrolocked.
Have you pulled any plugs?

 

[purg113]

no plugs pulled yet that is getting done real soon.

 

[purg113]

pulled the plugs now it can air out over night and I will refill w oil and see what happens in the morning

 

[purg113]

Its alive again pulled the spark plugs re filled with oil cranked it at the solenoid for 10 sec rest 5 min repeat 5-6 times let it air out for about 3 hours replaced spark plugs primed the system and she fired on the 2nd 10 sec crank.
what surprised me was it is quieter and idles lower before it idled around 1800 now it is around 900-1000 rpm but is smoking quite a bit but i hope that will clear up after running for a while. now latter today I am going to put a toggle in to kill all power to the electric fuel pump so this does not happen again.

Have you checked the pressure regulator for fuel leaking through it and into the vac hos that connects to the intake manifold?

It is highly unlikely, regardless of if the pump was on overnight, for the injectors to leak (especially that much fuel).

 

[purg113]

no injectors it it carberated.
