Gas In The Oil - Not Sure What To Do

[FredTT]

Hey Guys,

Well, my car has had this odd habit of almost dieing at idle for the past week or so. Well today it finally did it. It cranked, started, hung around 1000 RPM for a couple second then slowly died off. It wouldn't start again after thought. Thought it was a gas issue (maybe it was empty) so I bought two gallons and put it in and still nothing. It would kind of crank, sputer for a second, and die out. I thought it was the plugs (been running rich for a while now) but before I checked the plugs I pulled the dipstick and sure enough, I smelt gas on it. So, there is gas in my oil. What do you think are the likely problems? Injector stuck open, broken piston, etc.

I really doubt its the piston because A) it wouldn't of started for those few seconds and B) it should be making a LOT of noise. Of course, I could be wrong. Maybe a bad injector. How should I go about checking this? What else could it be?

At first it sounded like a vacume problem, but I take it you're not getting a check engine light. Are you running the stock injectors? Have you done any work on it?

[FredTT]

No Check Engine Light...Upps, forgot my sig wasn't there....

Maybe you tripped the inertia switch in the trunk.

[FredTT]

Nope, tried that already

Yeah, I guess you've tweaked on it. :lmao1:

Hi, my wife has a 73 super beetle and we,ve had a problem with gas in
the oil! we've had the carberator changed twice and it seems to
solve the problem for awhile. Well it has started to happen again,
can some out there tell me what is going on, how can this be
happening? any help would great. I feel we are just wasting money on
something that,s not curing the problem. Thanks

you don't drive far & fully warm up the car. In my 74 I would notice
the oil level creeping over the full mark after several weeks of
around town driving and would drop by 1/4 to 1/2 quart after long
highway trips. At first I suspected oil consumption problems but
this never happened after the initial usage if I was on an extended
road trip. If you have an excessive problem and your choke is
properly adjusted I'd suspect the fuel pump. They can leak
internally and gas leaks right down the pushrod into the engine.

Fuel pumps will dump fuel into oil. Cheap fix unless you want a
german pump. New carbs are usually jetted lean.....Craig

[MichaelsLilGray]

Hope something in their helps you...


Also.. David told me soemthing the other day i didnt think about till i posted this...

If you havnt tuned your car to adapt to the 39# Injectors... your car would run rich.. if it runs rich it has a tendency.. (like on motorcycles) to run into your oil. Which would cause the gas in the oil... So eh. As far as it not starting.. maybe the ecu needs reset. Unplug it for a while and try to start it again. If it starts your ECU as pushed for those 19# injectors.. you would need to tune it XCal style =P

[my86gt]

well since he is not Carb that will not help out, but you might have a stuck injector might ahve to take it somewhere and have the injectors cleaned.

[MichaelsLilGray]

Hey Hugo.. At least i tried punk =P

[BlKvNm]

ttt for fred

[FredTT]

I'm going to call AAA tomorrow and have it towed to my mechanic. I think it might be a fuel injector issue because when I arm the car, the Fuel Pressure doesn't remain stable, it jumps up to 80PSI and slowly drops off. Normally it just stays at around 80PSI until the car starts (then runs about 28PSI at idle).

I hope it's the injector and not something like the Piston. I def don't have the cash for a new shortblock.

[my86gt]

its an injector if its dropping on you then

[Bulldog Stang]

^^^ What he said ... Sounds like injector or even fuel pump ???

[mustangman68302]

hay man i dont know if this will help any but i had a ford ranger that used to get gas in the oil all the time, well it turned out to be a diapram in one of the fuel lines on top of the engine that would go bad and some how dump the gas back to the oil, but i dont know if they put thoes on the mustang or not but its worth looking to find out.

[speedfreak87]

Sounds like a leaky or stuck injector.

[FredTT]

Well, as it turns out, my plugs were all pretty screwed up. The were covered in soot from running rich. The problem was coming from cylinder two, the plug was completely destroyed, and was loose!!! Swapped them out with new HT0s and things seem to have returned to normal.

plugs can cause so many problems...people just dont realize all of the different effects bad plugs can have.

Glad you're gtg now.

what are HT0 ?

What caused running rich? Is the tune off?

[FredTT]

Autolite HT0 is a spark plug. $10 each. They run a heat range cooler then normal plugs. Well, I got that all fixed, but it seems that all that cranking took a toll on the battery. And when the alternator tried to charge it, it failed. So now my alternator is only putting out about 20 amps and the batteries aren't charging. :-(

And changing the alternator is a PITA, I have to pretty much remove everything.

~Fred

[Trimdog]

I would still do a compression ck.

[Trimdog]

I would still do a compression ck, the only way gas
can get in the oil is though the rings.
if you had a wet cylinder it could bypass the rings.
With a s/charger, you might not notes the low compression.
Dumping to much fuel in, just maybe identified another prob you
would not other wise find.

~Fred

You still have a running rich prob and those colder plugs will make it worse. You do need the cooler plugs to go with your blower but you are going to have to solve the rich problem. If it has been tuned properly you may have a dirty maf if you are running a standard tune that came with your blower you need to have it tweeked to get rid of the prob especily if your injectors are diff than what the blower instructions call for. there is no way to calibrate for diff injectors other than a tune or a tweeker. I would have a pro do it on a dyno because if you lean it out too much it can go into detonation and destroy your motor.

[FredTT]

I know, I've just been swamped so much that I haven;'t been able to take it out to Lethal to tune it. Not sure of any SCT tuners close to me (78212-downtown area). My job keeps me CONSTANTLY one the move this season, gonna be even worse next year.
