has anybody ever tried this??? (a good one)

[solowookie]

ok guys...

has any of you ever drained you oil, and replaced it with diesel #2, then let it idle for 10 minutes, next let it cool down, and then idle it again for 10 minutes...

then when you drain it you let it drain for a long time, and make sure you replace the filter too.

the diesel #2 has oil additives, and will have enough oil to lubricate, but it will not disipate the head effectively. will supposedly clean out any sludge, and also remove any oil glazing also. if there is glazing that is keeping the rings unseated then it will also solve that problem... (they also use kerosine instead of diesel #2)

anybody ever tried this??? (I'm going to do it on Insane Ewok when I get it running here in the next couple of weeks)

Watch out for leaks. You might end up dislodging gunk that has built up on your seals. Mains would be my concern.

That is what happens when you replace dino oil for synthetic on older engines.

it can also cause lifter problems due to cutting the carbon loose inside the engine, chunks of carbon can get stuck in the lifter passages and block the oil flow. I've also heard of adding ATF along with regular oil to clean out an engine as the ATF has higher detergent levels than regular oil.

I've heard of the ATF thing too... I don't think it would do near as good of a job as diesel though. if the seals were a problem I could change em though so shouldn't be too big of a deal.

all the old timers over at stovebolt.com swear by this method...

I've heard of the ATF in the oil (like 2 qts ATF 3 qts 5/30) too, same program as Jeff stated but add another flush with normal oil. It's suposed to "clean" out the sludge. I don't know if it works or not. You do have to keep in-mind where that sludged is going to go, the pan than the pick-up screen. That might plug the pick-up the screen, if the sludge is thick enuff. Bottum-line, if the engine is in good shape to start with, don't do it. But if the engine allready has problems, why not, whats it going to hurt? Maybe it will help free-up some sludge/stuck rings or what ever, but the damage has been done, and from there, it's a one-way street.

I have used ATF in very-small amounts in the intake, on engines that I plan on not running for awhile, idealy it should keep the rings "fresh-ish". Again, I'm not sure if it works, I haven't pull a engine apart after the fact. But it's worth a shot when I know the engines is in need of a rebuild any-way.

The only luck I have had.
I had a old 302 Ford that had a mean-rod knock, I changed the oil after several warm-up/slight drive cycles and the rod-knock was alot better. It would still knock, but once the oil pressure came around, it seamed to be O.K. Eventualy, the thing streached the timeing chain out so far it missed the crank-gear, so I sold it.

Edited, The byer knew what he was in-for, I explained everthng. So don't give me any-looks.

The diesel fuel sounds like those motor flush products that you can buy. I tried one but it didn't work. No extra sludge in the pan or anything. Maybe the motor was fairly clean.

The ATF works very well. ATF has been my favorite for cleaning engine and fuel systems. But like you said it can only clean so much... the ultimate would be to do the ATF treatment and then drop the oil pan and clean it and the oil pump pickup.

Dave brings up a good point about leaks... I also guess I plum don't trust it... at least not straight deisel... maybe a 50/50 mix.
