title says it all

i got 3 quarts of fuel in teh oil/sump, and cannot figure out how it got there or what to correct.

Crawdad

Stuck float flooding gas past the rings?

Did it run like crap before it dumped $4 of gas in your oil?

idanity

no.
it ran( now runs) normal.

it does however do the "warmup thing" backwards.

meaning, it will rev lower on startup and rev higher after a few moments of running.

wish it was opposite.
but
did that do any permanant damage, or
what are my options.
thanks for teh fast reply

Drain the oil and replace, but be sure to find out exactly how it is getting into the oil sump. There should be no permanent damage to the engine at this point.

What do your plugs look like? I would imagine they are fouled!

Crawdad

Yeah, definitely check those plugs.

OP, how long has it been since you changed your oil? I'm having a hard time wrapping my head around the fact that you had nearly a gallon of gas in the pan, yet it was running fine. We're all missing something here, I think.

abecedarian

correct me if I'm wrong, but isn't the fuel pump driven off the camshaft? maybe the diaphragm in the fuel pump is bad....?
that's the only way I can see so much fuel entering the engine without affecting combustion.

abecedarian

not to mention it would drip straight down through the timing chain cover into the oil pan.

surf4runner

pretty much just flushed it out.

i had no issues when this happened to me w/an improperly connected electric fuel pump-manual power switch, not a 'keyed on'

idanity

thanks everyone.

to answer
1. just did the oil change/ filter etc. not its so clean, i cannot find out where the level is
2. plugs were blackish, but i brash bushed em back to good condition (no cracks, or damage, procelain is white too, little carbon scarring, not much)
3.i heard the fuel gurgling down into the carb the night before, or morning of finding the fault...

it somehow kept the flow going.

but what about the smoke.
no coolant loss. no sweet smell, and it happened 6 months ago (blue smoke) for about 3 minutes, and fixed itself...

main issue is of course the carb.
thanks for the replies

idanity

and do we have electric chokes ??

abecedarian

the choke should be electrically heated.
there should be an electric fuel shut-off valve in the carb.
electric or mechanical fuel pump?

idanity

mechanical pump...
i could take a few pix...

abecedarian

well the fuel bowl in the carb doesn't hold 3 quarts of fuel so it's impossible that all that fuel came from the carb while setting overnight. Even then it's hard to believe it leaked that much into the intake since your last oil change particularly since you're saying it runs fine, save for the slow when cold- normal when hot issue.

check the fuel pump

idanity

i heard it "gurgling" after the keys were removed..
it may have been doing' ever so slightly, but overnight was enough..

i drove it fine, parked it, then it wouldnt start. (after 45 seconds of cranking, it did, and i could move it 3 times, but not more then 20 feet.

now/ after the oil/+ filter change, its all okay, but this happened once, i gotta find out why/ how to resolve it so it doesnt happen out in the desert

Crawdad

God, I wasn't even thinking about it being a mechanical pump. YES, CHECK THE PUMP. There is a rubber diaphragm in them that pumps the fuel from the tank. When they go bad, that diaphragm will rupture and leak directly into the crankcase. I would almost 100% guarantee that's where your problem lies.

idanity

its a manual fuel pump, would the carb still have an elec. shut off valve..?

thank you all for the replies

iselloil

The diaphram in the fuel pumps bad.

CyMoN

yes on the carb there is a fuel cut solenoid.

drew303

yea theres a solenoid that cuts fuel off when the engines off on the carb

but i bet its your pump to, leaking into the front cover.

And so people stop asking, 22rs never had electric fuel pumps.
