Now what????

LatinPorsche911 · 08-11-2019, 06:25 PM

After going through these experiences....

I am losing my patience with this engine!!!!

Is this possible?

So prior to today... before draining the oil... the car did start (no starter or battery issue), it was only smoking quite a bit. But it was running, did not want to accelerate... I guess its possible that a few injectors may be dirty (2 of the 6 were changed 2 years ago)

I was asked if the oil smelled of gasoline, it did... so I changed the oil today, replaced oil filter. I allowed the oil to drain out since Friday afternoon. The engine was warm so I thought the oil would flow out quicker and with the gasoline, even more so. I figured it would be quite empty...

So put in 5 quarts and then another 4 and it over flowed a bit,... so I think I over flowed with oil.
I hoped that maybe once I turned in the engine it would move around and go to a good level.
So started the engine... and the big NOW WHAT???

It struggled to stay running for at least 10 or 5 seconds.
The starter works fine, battery has juice, but doesn't want to run
If I press the gas pedal doesn't do much. Turn it off.....wait 30 seconds and turn key again and starts right up and dies...

If it was the injectors.... then why was it working and running (although with the smoke) prior to me taking old oil out and putting new one.

What the heck is going on? I don't think having way to much oil would cause this or can it??? For those that are busy and reading the previous 2 threads would be much time wasted...
This is what has been changed in the car:
Starter, fuel pump, fuel filter, FPR, Oxygen sensor, speed sensor, reference sensor, fuel relay, Cylinder head temp sensor... I think that's it

Any thoughts, advice,... anything would be appreciated.
Thanks

If you have fuel in the oil, it is coming from the fuel system, which means it is squirting more fuel into the cylinders than you can burn. Probably being flooded at start up, and more fuel pour in while the car is not running.

Do you have spark? Is your fuel clean, or at least not real old? Are the injectors clogged? What is your fuel pressures? Are you troubleshooting the no run condition? I did not read the prior threads.

Edit: I read the first original thread. Scarceller has you pointed in the right direction. I would advise you pay attention to what he is telling you. One thing at a time, and start with the basics.

Not to be a smart ass, but did you drain oil from both the tank and sump??

Did you drain the oil from both the tank and the sump?
2 locations to get it all out.

This is like watching a train wreck... I feel bad for the poor car.

Wondering this too. Even after changing oil 15 times over the years, a few years back I was distracted and totally forgot to drain the oil tank....it happens

LatinPorsche911 · 08-12-2019, 10:10 AM

Man... I totally forgot about the sump holding area. My bad. Just several issues that need to be juggled at the moment that take priority like taking care of dad and dissertation. So yes, poor car but in the end, it's just a car and if I had dynamite I'd wouldn't mind seeing it blow up. Hahahha

But still having contaminated oil with new oil would not explain why it dosen't want to start or run. It's not as if it's been sitting without running for a long time like before. It was running on Friday, smoking but running.
What could have happened now?
Thanks guys for your help

Being that over filled with oil likely, you probably sucked a bunch of oil into the breather system and intake. You likely oil fouled your plugs causing a running and starting issue.

If you have not drained any oil out yet, I would start the whole oil change process all over again.

Drain engine and oil tank, then add back in 9 qts, and start from there. You can add back in the next 1-2 qts once it gets running.
I once drove a regular sump car that had too much oil, thing would hardly run...

And, check the plugs, etc to make sure they are dry.

Just to be clear, when the oil is overfilled, the engine, at start up, will force the oil out of the oil tank in the right rear fender, up through the overflow/breather pipe, and directly into the air intake. This pipe is there to channel oil fumes into the air intake for combustion, not for direct oil transfer. The oil in the air intake filled with oil then is pulled into the combustion chambers on the piston downstroke, The entire interior of the engine's combustion chambers is then coated with oil, particularly the spark plugs and the valves. Excess oil then is pushed out the exhaust. It is the rare engine that will keep running under these conditions. When you get it started again, after draining the oil completely, do so at night in a mosquito infested area because the oil soaked exhaust will produce a thick fog of blue smoke as it gets hot which, I am assured, is toxic to all life as we know it.

And do not drive it until you get the oil level right because you can do serious damage as well as have your car catch fire

LatinPorsche911 · 08-12-2019, 12:30 PM

Ok... thanks so much you guys for the thorough explanations. Definitely explains the difference. You guys have given me a bit of peace of mind. Will do those things today.
Thanks again

PS. Since the oil that is inside is more new than old.... can I reuse it like in a truck or Subaru little by little or is it ruined completely?
Thanks

The only oil that goes into my engine comes directly out of a new plastic bottle of oil

Others may be more casual about it

Would you eat a piece of pizza that fell on the sidewalk?

Don’t forget to check your airbox for oil....assuming you have an SC....I’m not familiar with other years

Targalid · 08-12-2019, 01:31 PM

You can drain the oil into a clean container and, if you are worried, pour it through a cloth to remove large particulates. Considering the cost of engine work, the purchase of more oil may be the best plan. Walmart has Mobil Delvac 15-40 with extra ZDDP for $11/gallon.

LatinPorsche911 · 08-12-2019, 01:55 PM

Sorry.. guess I was not clear. I did not mean to reuse the oil on the Porsche but on another car.... the fact being that there are about 9 quarts of new oil and whatever amount of old oil that was in the sump.
Be a shame to throw that away.
Can that contaminated oil be used up in a truck or ???
