engine flush with diesel

[@frankwaddle3991]

Had a customer take his Lexus to the dealer and they did a engine flush and on his way home spun a bearing on the way home.when you flush a engine all that junk goes through the oil pump and the bearings.not a good idea.

[@partsshooter]

@frankwaddle3991 I'm gonna respond to this because I don't think you or others understand how the lubrication system operates. If there's preexisting damage, it's irreparable. Sludge is superficial, and there are safety mechanisms in place. Such as a strainer, pump to pulverize and filter to filtrate. The oil filter does a great job doing it's job. These cases you guys bring up are case by case situations and are circumstantial on individual bases and should be treated as such, but yall stories are interesting either for or against this procedure. I provide evidence in my case with the lack thereof on your and others behalf. I can back up my claim while yall can't. I'm simply not gonna allow you to instill fear with this process due to it meeting the necessary criteria for this. To add, I don't put the dealer on a pedestal because they're human that make mistakes just like me, thing is they have more heads than my 1. Stick around for the update, despite my proof not being persuasive, this case doesn't live up to your claim and others of failing. When done properly you can achieve best case on a bad situation. This is a TREATMENT not a SOLUTION

Running an engine on diesel fuel, transmission fluid and sludge for more than 30 seconds seems like medical mal-practice to me... Not sure why you didn't at least add 2 or 3 quarts of oil... but even that would be extreeme. At a bare minimum the valve covers and bottom oil pan needed to be removed and the attack on the sludge begun with some type of solvent based fluid like Marvel Mystery Oil or some other mild solvent cleaner and a soft scrub brush. Once the top was cleaned then start on the bottom end, put it back together and fill it fill it with cheap oil and a motor flush and run it for a few minutes... drain and refill with oil and call it good. The risk of damaging an engine by wrecking the oil seals or damaging the oil pump with diesel fuel may or may not exist... so that's why we are watching you do it to see if you get away with it!

[@justme-n-gracie]

I agree that this does work... I have done it and this was shown to me by my dad.... as you said every case is different. I did have one engine fail afterwards.... Ithe first sludge removal loosened and removed a lot of the sludge but not long after sludge clogged up the screen on the pickup tube and the engine spun a rod bearing. Now I wouldn't do this just once.... I would repeat the sludge removal until the drained fluid is much clearer then clean cheap oil for a couple hours than another oil change. I would strongly recommend that people watching this video have this process done by a reputable mechanic. My dad also warned me not to rev the engine while the cleaning solution is in the engine... he said THAT results in spun or damaged bearings. Maybe less likely with modern engines designed for low viscosity oils... We were doing this on engines made prior to 1980. The engine you are working on here... I would bet that cheap oil was used by whoever changed it.... no detergent action. I only use high quality synthetic oil now.

[@stilllearning1160]

Fellow mechanic of 40 + years experience (an Aussie). I have come accross many cases, and yes, some as bad. There is only one way to say it, 'owner abuse'! Policy to proceed in such extreme cases: - ' All care, but absolutely NO responsibility'. What might I do? Step 1 evaluate. Is the oil light on? - because that's a problem. Engine is either too low on oil or the sludge has blocked the oil pick up screen. Some screens are quite small. If no oul pressure snd oil level is enough do that it should have oul pressure then talk ro owner: sump needs to come off and evaluate further. Some oil lights trigger, not in response to low pressure (a real oroblem) but to oil level being down by say , 1 litre out of 6 litres or more of total capacity. ( Not so alarming). If the latter then: Step 2: add a good flushing cleaner with 1/3 - 1/2 litre of diesel fuel. Idle for an hour, say, then, Step 3: drain engine oil remove and drain oil filter. If filter is quite bad, discard it,. If filter not quite so bad, refit oil filter &, Step 4: refill engine with another dose of strong and proven engine flush and fill engine oil to normal volume but with a cheap multigrade oil from any auto parts store. (It will only be in the engine for a few hours and is really just a carrier for the cleaner and the sludge). You Can add another dose of diesel fuel, say 250 ml, as part of the total volume. Step 5: park car away from garage / shop and let it idle for 2 - 3 hrs. Can be at a fast idle, say, 1500 rpm etc if you can do it. Step 6: redrain oil & change oil filter again with new one this time. Step 7: refill with correct / optimum engine oil to correct level. When doing this procedure for clients whose engine has become just a hit too dirty this works a treat. Often when finished it can be hard to see the oil level on the dipstick. Have had some cars where doing this helped but would not shift the carbon built up at the top of the engine (rocker gear, rocket cover and oi breather etc., which runs cooler). Think BMW with extended (factory servicing).

I've never seen this done personally but my brother talked about this when I ws a teenager in the 1960's. It isn't an attempt to fix anything. It is an attempt remove the sludge in order to allow the engine to last as long as possible.There were a number of approaches. The approach as I remember was to use regular oil with the diesel and flush 3 to 4 times replacing the filter each time. In some cases the engine would be filled completely with diesel and allowed to soak a day or two without running the motor then drained off prior to filling and running ther engine a few times. One needs to remember that modern filter systems do not filter all the oil that is circulating. Once the oil pressure reaches a certain point the spring in the filter is compressed and the oil will bypass the filtration membrane...this makes it important to lower the idle rpms as much as possible which in the old days was fairly easy to do but not so much with electronically controlled modern systems.

When I got a really really bad one, like that one, I would just use engine oil, and change it at about 500 miles, then one more time at 500 miles, and then I would encourage a couple more early oil changes... before going to once every 3,000 miles. I wouldn't flush an engine that bad; I'd keep changing the oil early until it was reasonably clean before I would use an engine flush.

[@Tiberius_I]

Smart man! There is one and only one engine flush that is actually safe for the engine, and that's engine oil with nothing added. But now we have an actual oil that even does that for you (Valvoline R & P).

[@Montgomerygolfgator]

#2 Diesel has lubricator in it (diesel fuel injectors need lubrication) so it might be a bit better. Do check for Biodiesel content if you do it these days. Biodiesel runs in diesel engines just fine, but liquid chicken probably won't help flush your engine 🤭.

You could have driven it around all day with the fuel in the crankcase, then let it drain for an hour. Refill it with fresh oil, drive it for a few days, drain it again. If it shows clean, it should be good for regular month oil changes.

You only need to add 500ml of diesel to normal engine oil and run it for 30 miles or so, then fresh filter and normal oil. Do another flush after 500 miles with 500ml 9f disel again and it should be good. Dropping the sump and cleaning it out will help alot as well.

When it is that bad...2-3x flushes might be needed... Best way is to replace 1 quart of oil w/ diesel, fill up 15w50 diesel oil (to be thicker because diesel will thin it) new cheap filter, run for 15 minutes, drain, repeat until the oil comes out almost clean and not jet black....then fill with manufacturers recommended and a good filter and all is well...if it got heavy buildup like that...2-3x might be needed...straight diesel is too thin and can cause massive wear on the bearings, even at idle

[@T_Burd_75]

I do not recommend flushing an engine with kerosene/diesel. When I was 14, I bought a 1976 Ford Elite that had a 351M engine that seemed to run perfectly. When my dad and I changed the oil, the oil had clumps in it. He got the idea to flush it out with some diesel. So, we put the diesel in it and ran it for a little bit, then drained it and filled it with fresh oil and filter. Shortly after, a rod started knocking and the oil light stayed on at idle. We pulled the engine in my brother's father-in-law's garage and tore the engine down. The bearings were all wiped. Since I was only 14 and knew nothing about rebuilding engines and my dad didn't know much more than I did, we ended up scrapping the car.

I have a 2017 pathfinder bought used with 47k miles in 2021. I used mobile one 0w-30 in it recommended by the manual. Oil was always vomming out extra dirty and smelling burnt. Also would have bad valve noise on startup and after driving down a 1/4mule driveway. I ran liquimoly 5w40 for two 3000mile oil changes and then swiched to shell rotella T6 5w40 @7000miles. Top end noise has greatly improved and oil is much clearer and does not smell at changes. Also the manual says you need to wait 10 or more minutes after running the engine for the dip stick to be accurate. Guess the oil needs to drain back into tthe pan.

[@arkangel847]

Should refill with diesel engine oil , has detergent in it ?

[@Combat_Pyro]

You could still put a can of Seafoam into the oil with each change as well. That will help clean a lot out due to the length of time of contact and the use at driving speed would give more splash contact.

[@Elrafau]

Rather than do an engine flush with some fancy expensive oil additive 'potion', I'd just drain off the oil, put some cheap oil in, change the filter, run it like you stole it for 500 miles or so, then swap out the oil for the better stuff. Oil has cleaning detergents built in, it naturally flushes the engine and helps to reduce carbon and sludge build up. Better still just do more regular oil and filter changes, I change mine every 5k miles, even though the service interval is closer to 20k miles⚠😲😳

Chemist here, diesel is a good choice for doing what was done, maybe a little less so the bearings don't get a hard time/ add some ATF. However, you need to pull the sump and clean the sludge out of the sump as it will block the pickup and starve the engine of oil. You might get not away with 3000ml before it happens.....

Used to clean my engine with a liter of diesel. Before oilchange I would top the oil up with the diesel let it circulate, leave it over night than warm up the engine with driving around the block with not so high rpm and then change the oil and filter.

I've been doing my own oil changes since 1974. With a few exceptions (4000-mile intervals with a '68 and three month intervals with an '86), I've stuck to the 5000 mile rule of thumb. The way I see it, if the oil has turned black, you've waited too long. My '88 Jeep Cherokee lasted 35 years.

@Anthonytheredneck ATF haven't been as aggressive as diesel in those extremely sludge engines I've had in the past. ATF is just safer when mixed, which allows us to drive on.
