kerosene in oil

[madvette74]

I heard once that you could add some kerosene into your oil and run the engine for a few minutes, this would clean any sludge ect... I have some antifreeze in my oil, and I thought (or hoping) this would get all of it out, the problem has been solved about the anit freeze.. any ideas???

I have heard the same thing but do not do it. That will break down lubrication on all your engine componets like the main bearings and what not. It doesnt take much to score them either, and then voila you have to rebuild it.

Anti freeze is heavier than oil and should go to the bottom of your pan.
Just change your oil and filter, run it for a minute or two but not up to operating temp.
Then change them again.
That should get it out.

does the same apply to water??

 

[Ken]

I haven't done that (or even heard of that) since I was a fifteen year-old working my first gas station job. :L

It will definitely clean the sludge out of old engines, and make a lot of smoke while doing it, but ... :nono

What do you mean by "some" anti-freeze in your oil? How did it get there in the first place? Are you sure the source of the problem been fixed before you proceed any further?

Sure,oil floats on water.

Antifreeze in oil is a very bad deal, it plays hell with the bearings. Hopefully you haven't run the engine much in that condition. I would not put kero in the oil, you need all the best lubrication qualities you can get at this stage.

I once wrote a reply to a question of how to get antifreeze out the engine oiling system. I had to do this on a Chevy 2.8 V6 installed in an '83 S-10 Blazer. You might find it in the archives.
However, I did not "run" the engine with kerosene in it. I filled the crankcase with kero and pumped it through the engine by driving the oil pump with a 1/2" drill motor. I flushed the engine this way three times, each flush lasting about 5 minutes. I changed the oil filter and used fresh kerosene each flush.
I quit flushing when I observed no foaming or other signs of water/ anti-freeze in the flushed kero. I followed this up with two flushes using 10 weight oil and finally a flush using 10W-30. Refilled the engine with 10w-30, ran (first time I actually started the engine) it for 10 minutes and changed the oil and filter. Refilled and did the same after 500 miles, then went back to my normal oil change interval.
Seems like a lot of work and it was, but much less than removing the engine and less expensive. Have driven the vehicle another 50K miles since the flushing with no problems. Still holds 40 psig oil pressure at cruise. Has 270,000 miles and has never been rebuilt.

I replaced the intake gasket on my lumina, the lifters and everything else was mess, cleaned off what I could then put a quart of trans fluid & 3quarts of oil in it, let it run for awile dumped it then filled it with oil & ran it for a week changed it again and everything is good so far.

MMM..
where can I buy the kerosene??

 

[madvette74]

what does the ATF do? that helps remove water. curiuos to know how many guys change there oil in the spring? I usually just crank the engine over a few times, once a month, I dont let it run.. and I change the oil just before I drive it, my oil has never seen more than 1000 miles of usage.. does water build up in the pan over the cold winter (new england)

Just about all auto parts stores and auto depts in stores sell a special solvent for "washing" the engine that you add to oil, run, and then drain. It comes in an old style metal quart oil can the last time I saw it.

This is not a recomendation to use it, I wouldn't put it in my 'vette.

Rislone (sp) the stuff in the yellow bottle is supposed to remove gum and deposits. I had a tapping lifter in a non corvette 350ci. Added this to the crankcase, it freed it right up. No problems 72,000 miles later.

Back in the 50's & 60's at our service station we used kleensen (?) , a cleaning solvent mixed with bulk oil to flush out engines quite often. Used it in my 327/350 vette engine a few times without any problems. Sure would clean out the sludge, etc. Don't know if I would do it now.

 

[madvette74]

well, i am past the point of starting motor, I removed the radiater and timing covers then valve covers,, i noticed the water (milk shake) on valve covers, although it was not a lot, but it's there.. I am going to drain my oil, add some oil and filter and prime it with drill, then change oil and filter again, I would of never new this was water in the motor, but I am installing a new cam..

My understading is the atf has detergent & lubricant to help clean out the water, I just hope you've found & fixed the problem that caused it to leak.
It was my first experiance so i'm no expert but it seems to have worked in on wifes lumina 7,000km since gasket problem but i think i better get rid of it soon, water pump went last week & i'm thinking anything with bearings may not have liked the antifreeze.

Ive heard of mixing a little Kero with the oil, running it for 15 minutes, draining and filling with oil. The guy that I heard it fron said it used to be a nightmare too beacuse it would unclog one area in the engine and clog another.

 

[vett boy]

Believe it or not try mobil 1 . Change the oil after 3000 miles. It will look like it came out of a diesel.

I've used ATF a number of times to free up sticky lifters in big blocks, put in a quart drive it a few hundred miles and get it out within a couple of days. ATF will cause seals to swell if you leave it in to long (that's bad). I never heard that it will remove water though.

It sounds like you repaired the problem at the source, you might also go to a jiffy lube and have the engine power flushed. I've been a bit leary of that in old motors, who knows what might break loose and clog somthing up.

Good luck

in the old days if you bought a old car you had to ask what oil they and not change type because if you put detergent in a motor that had been running nondetergent all that crab would brake lose & mess everthing up & plug the rest up
