Diesel As a flushing agent

Thanks to Dell and his jack under the pipewrench trick - I got the drainplug out. In addition to the gallon+ of ancient motor oil, MMO, ATF, white vinegar and PB Blaster there was about 1/2 inch of sludge in the bottom of the pan. I used my finger to pull as much as I could out with the oil but I'm no basketball player....there are places out of reach.

When I first got the thing un-siezed it pumped a "quantity" of the thinner part of this stuff into the oil filter cannister and god-knows where else.
I've got a supply of cheap oil to do at least two complete clean-oil flushes before I put a new filter and "real" oil back in it to run.

So amidst all this - I think about putting a gallon of diesel in the pan to soak a day or so - so it combines with the sludge and takes it out of my tractor when I drain it.
Then I think about getting two-gallons - and using the second one to refil a second time and maybe turn the engine over via towing enough to flush the entire oil system w/diesel.

I also thought of flushing the back-end of the tractor too....

This is all just thoughts while I wait for my next batch of parts(electrical) to come in so I might be able to actually start it.
At which point does this line of thinking become a bad-idea? Also - is using a shop cloth in the cannister for the first flush run instead of a new filter a bad idea?

I don't know for the life of me why anyone would want to circulate all that sludge sitting in the bottom of the oil pan through the engine and wait for the filter to trap it when you have the opportunity to clean that sludge out of the bottom of the pan NOW. Diesel will work just fine, kerosene will work slightly better. Hell, hot soapy water will do the trick.

Yes, HOBO, your comment just jogged my old memory. My Dad had a Lincoln SA200 and he loaned it to a fellow, who 'generously' changed the oil in it while he had it. Well, shortly all the bearings went west to see their ancestors. My Dad always said the he had forever used non-detergent oil in that machine and that this fellow put in high detergent Amalie and broke loose all that sludge, that had been previously perfectly happy just lieing there , and set it free to clog up the works. If he was correct, then maybe it lends some credibility to "let sleeping dog lie", or "if it ain't broke, don't fix it".

A quart or so of diesel would clean a lot of that sludge out, BUT remember those old Fram ads, Pay me now or pay me later, Get yourself a six pack of filters,Cheap insurance against pushing that junk through your engine. Start her warm up a bit, CHANGE the filter. REPEAT often. The sludge will loosen with running and will drain easier with a warm engine. Ever think about E85 as solvent, cheaper than diesel and really cut muck.

Learned another thing, never worked on any "N"s didn't know the filter was end of the line, should have made for clean oil, with all then babbit chips in the filter.

We ran diesel thru my son's 351C motor that had a LOT of sludge in it. This was on the reccommendation of our mechanic. It got some of the sludge out but not all. Also loosened up a lot of crap that was now sloshing around the motor. Finally when my son got into auto shop they took the motor out and overhauled it. Still had a LOT of sludge in it. The only real solution for sludge is to tear the motor apart and clean it. You'll never get all the sludge out regardless what products you run thru the motor.

It might be better to use solvent in your rinsing program, probly costs about the same, and has better cleaning properties-ie; it breaks down oil based sludge and gunk AND if you filter it (DON"T use the wifes stockings{do not ask}, a coffee filter works) you can re-use the stuff.

Bruce (VA) said: (quoted from post at 22:04:07 04/14/08) It acts as a thinning agent. Kerosene is also used in Arctic climates to thin the motor oil; otherwise, the engine would never turn over because of the thick oil. Once the engine warms up, the kerosene burns off. But, the engine still has oil in it even when it started up.

I see no problem here.

Well, I read the posts about diesel, but..... ...
Cat labels right one the side of their $100,000 tractors says dilute the motor oil with diesel in arctic climates, so it can't be too bad. Now, they didn't say straight diesel was OK. Some mix might offer some extra cleansing.

As Bruce said. if you just want to dump a couple gallons of diesel into the pan thru the fil to slosh around by rocking the tractor.. then let set, and then drain.. that's fine.. but for sure don't pump the diesel thru the engine.

the sacrificial clean oil flush will probably be a good idea. After the diesel, change the oil.. run it till ewarm.. then change it again. run this next oil for 10hrs or a day of 'play'.. then change to real oil and the filter too. can use cheap 3.99$ fram c3 for these.

I've done this on real gunky engine.. like my jd B that had a 50/50 mix of water and oil when i got it!

Yep, it's a very bad idea. Diesel fuel, like kerosene, has no lubricating value at all. It's like running the engine w/o no oil in it.
