Flushing an engine with paint remover - will it work?

[@jasonmarange5973]

I've used transmission fluid my whole life (well since I became a mechanic) it cleans super well and doesn't have any adverse effects on the engine. Run it a while at idle flush it out and it's clean as a whistle. A lot of cleaners have tons of detergents that really hurt viscosity and can be corrosive. Transmission fluid doesn't do that, and it also takes high temps well where as a lot of flushes effect that and the oil stability. Used this method the 20 years I've been doing this with great success. I have heard of the old school guys using thinners and stuff like that tho. But, great video!

[@fishrsa9046]

I've heard some long time mechanic guys recommend diesel, to me it sounds like a horrible idea 😅

[@tomasnokechtesledger1786]

You use Full (pure) (only) ATF in the sump, or a little mixed with engine oil?

[@jasonmarange5973]

@tomasnokechtesledger1786 I'll usually just add about quart to the oil depending on how bad it's sludged up. Always just use as an additive not a replacement of the oil. And you can do it a couple times of needed. Or do it changed the oil then next oil change do it again. It works well I've used this method for years with good results.

It’s not uncommon for engines to fail horribly after a flush because clumps get into the small channels that transport oil. It just seems to take a couple of weeks to notice damage depending on how much the engine runs. I would really like to see a follow up on this car. :)

Here in America near the Southeastern side of the continent we generally use transmission fluid for our engine flushes. With a 1 quart transmission fluid for four or five quarts of engine oil placed inside of a running engine for about 45 minutes then change usually does a pretty good job removing all the sludge and carbon buildup 🤷🤷.

[@johnhenke6475]

In my meshanic days this dealership I worked at took a dodge van in traid. It had ten pounds of oil pressure and all the tappets were clattering. I took out the drain plug and nothing came out. I couldn't figure it. I went to get an opinion from another mechanic. By the time we got back there was a long black drip hanging out of the drain. I shoved a long screwdriver through it and at last filthy oil started running out. When it stopped I replaced the plug and put on a new filter. Then I added a gallon of solvent. Upon starting the engine the pressure went up to 30 PSI and all of the lifers quieted down. I drained it and filled it with transmission fluid, ran it for a while and finally put in regular motor oil. It ran great!

[@otm646]

You don't need to do anything this aggressive. Simply run a synthetic oil for a few oil changes, you be amazed at the sludge and gunk that come out.

[@tenmil1]

The thing about using atf is it can be misleading. It burns and turns dark at a temp lower than combustion temps. If you fill your car up with atf and run it and the fluid you drain is super dark it doesn’t necessarily mean you’ve cleaned anything it only means you’ve heated the oil enough to “burn” it. I’m not saying this doesn’t work, but would it work any better than using a very high quality high detergent motor oil? I dont know.

Love your channel ! Very interesting test you performed. It reminded me when I was young, back in the early 1980's. I worked at a small "hole in the wall" auto repair shop. I was 20 years old. The owner was a WW2 veteran and had some pretty strong chemicals still stored in his garage. He'd bought them cheap as government surplus in the late 40's . For some reason, American engines in the 70's and 80's were full of sludge!!. I know they've improved since then but petroleum products weren't that clean back then. This Oldsmobile was loaded with sludge. SO ONE DAY....my boss hands me a quart of the stinkyest black colored chemical I've ever smelled. It was horrible!! He says, "drain the oil out of that engine, and put 4 quarts of WATER and one quart of the chemical into the engine! I said WATER?? But that will ruin his engine! "NO IT WON'T" my boss told me...so I did it. The boss said "park the car across the street and let it run a 2000 rpm for a half hour! Steam was blasting out of the tail pipe, the entire time, and the horrible smell filled the entire neighborhood!! The Steam kept blasting out of the tail pipe for over a half hour. The boss says, "Okay, bring her in and drain it". The "oil" was coal black , thin as gasoline, and it burned my eyes and nose while it drained. I was choking! I removed the valve covers and { was shocked! The valves, springs, rockers and heads looked brand new!! I said "where did you get that stuff Bill"!! He said "never mind that"! Its been banned by the EPA since the 50's!! hahaha! That was the last time we ever used that chemical. Never knew what it was but boy did it work!!

In the US, most paint stripper contains methylene chloride. Usually a thickener is included in a stripper formula as MeCl2 vapor pressure is fairly high - it evaporates quickly. The thickener allows the chemical to soften the paint before it evaporates. Methylene chloride would dissolve grease very well!

[@Mikej1592]

I thought Methylene chloride or dichloromethane was actually been banned in the US. But this is also likely much different than the Muriatic or hydrochloric acid based paint strippers I am used to using, which is why I was terrified watching this. They were mostly likely using some solvent based paint stripper, and I never even knew such a thing existed. Since I have only ever seen and used muriatic acid based strippers, much more dangerous.

What was in there was like sludge the dealer wouldn't touch it. I used a regular engine flush product on it three times and then did regular oil changes with a quart of transmission fluid for the 5th quart 2 more times, over the next next 2 months. At the end the oil was clean and the motor was running properly. An old mechanic told me the tranny fluid trick. He said it contains a lot more detergents than regular oil and should clean it up.

i would be also concerned about what damage it may have done to the seals, gaskets, sealant, etc?

[@dewaynewhitney5703]

I use about 1qt or 1 lt of diesel fuel before I change the oil and filter. LS engines get really hot and cook it on, and diesel fuel cuts it off really good.

[@squishy312]

Apparently you can clean catalytic converters using 1 gallon of paint thinner to 10 gallons of gasoline. Let the engine burn through all of it at 2,500 RPM or so. Or drive it for about 200 miles. It has to get hot enough to vaporize everything that's clogging it. Paint thinner makes it run extra hot.

[@soaphelps]

Had an old guy use water. Get the engine hot rev it up and pour in the water. Also seen someone else use and swear by using atf. I have used diesel with great effect. It keeps enough lube to not destroy things.

[@soaphelps]

Poured down the intake.

[@K-Effect]

I’ve seen people flush motors out with ATF automatic transmission fluid, and it seem to work good. If the motor is really worn out it will smoke and burn oil really bad afterwards because the carbon build up is gone

[@angusnz7910]

I’ve always flushed every second oil change with diesel fuel. Something my father done and I’ve carried on for the last 40 years myself

[@jamesreichardt4476]

You should do what cleans a DPF filter!

[@aussiebloke4601]

i have a cylinder head reconditioning plant and I use a tank of methylene chloride to clean the parts, it is very fast to remove oil crud and carbon. Surprisingly the main ingredient in paint stripper is methylene chloride.

[@nsmith473]

Several years ago I used synthetic oil in my 2008 GMC Sierra. It disappeared. The level was dropping and it wasn't leaking, and I really couldn't see it coming out the tailpipe. Fearing that it was gelling up and sticking in the motor; I drained the oil and filled the engine with diesel. Let it sit a few hours, then cranked the engine for somewhere around 3 to 5 minutes. (scared to go more) Drained the diesel, changed the filter. Filled with oil, ran 15 mins or so, and again replaced oil and filter. It has ran like a champ since, always using real oil, not synthetic.

[@fredclements6843]

Me an my dad used Diesel unplugged the coil an spun it over for awhile worked really good 👍

[@Random-bm7ho]

You can get the same results by putting diesel in the oil. Only it won't destroy the engine internals and seals.

[@Ravichandran-n6w]

Me too,I did it for my c200 mercedes

[@TechOne7671]

Interesting experiment but what does the main bearings think of it. How does the paint thinner effect the lubricity of the oil ?

[@johngillon6969]

I don't think we are going to hear about it leaking oil out of every rubber seal on the poor engine. that will begin in a week or so.

[@SwapBlogRU]

@@johngillon6969 I'll ask about the fate of this particular one. The guys over at G54 are smart, it it's possible - they usually don't let good engines go to waste and at least try to preserve them for future experiments (as you will see in next Tuesday's episode).

Great info, will you do one with diesel fuel in future? Thank you

[@Goojy-Gooj]

Main crank seals etc will have swollen up, probably fixing any minor seeping...but at a price of a vastly shortened life. Squirrely sellers will add acetone or similar to oil before selling to stop leaks in the short run. Cool experiment tho. Wish they'd have filled it all the way up and let it sit for a night, drain abit and then run/flush it.

[@terrykennedy7422]

I was thinking they were going to fill the sump up with only paint remover. Run the motor and see what happens. I've used diesel to flush old oil before.. It did work.

[@hornetscales8274]

I know a guy who would drain his oil and run 2 quarts of diesel through the engine before draining and refilling with new oil. The engine was noisy for sure during the "cleaning". No idea what good or bad came of it though.

[@pflaffik]

If it was noisy it has sustained damage but impossible to say how much. He should mix diesel with oil for the cleaning, or not clean at all - the residues sits on secondary surfaces, not contact surfaces

[@meyawabdulaziz3863]

cool i think many other solvents would work like diesel , kerosene

[@CompproB237]

The way we cleaned very dirty parts was by putting them in a large metal trash can filled with degreaser and water. We'd heat it up, put the disassembled engine parts in, then let them "cook" for 20 minutes. Pull out the parts, scrub the stubborn gunk, then put it in the degreaser for a little while longer. You'll have nearly acid-cleaned parts in an hour.

[@gramps6334]

Kerosene works great. It's oil based and won't hurt internal parts.

[@damoncrowfeather4655]

As the oil filter becomes clogged, it will activate the bypass valve in the filter. If a person does a flush every other oil change.. They shouldn't really ever develop a sludged up engine. But, manufacturers of modern oil will tell you, if you change your oil regularly, you won't develop sludge, and in fact engine flushing is not necessary. Transmission fluid is a good flushing fluid, as it has lots of detergents. Some ppl use diesel, which is very aggressive to rubber seals and gaskets, and you can trade a sludge issue with the issue of a very leaky engine.

[@dutchymon]

Follow the paint remover with a paint thinner flush to remove the softened up residue and then clean motor oil.

[@larrysorenson4789]

Is there any real, hard data that addresses the effect of gunk coated valve bottoms on performance? Air flow? Rebound time? Etc.

[@DUKE_of_RAMBLE]

I remember around 2003 I was using some Parts Degreaser on... I think it was the throttlebody on the 1991 Firebird (350 TPI) I had. The degreaser came in an all-metal paint can, was a name brand product but don't remember who by. Quite sure it's the same stuff that was used in a Parts Degreaser Bin (the kind that pumps this fluid through a brush). *_Anyways,_* it was certainly a learning experience!! 😳 The stuff doesn't make you gap for breath or make your eyes water, so I was just kneeling on the garage floor with the van open and scrubbing away at the gunk on the part. It had only been like, a minute maybe, and I noticed my hands.... Imagine how your hands looked when you've been in the bathtub way too long as a kid, and multiply that x2. They also starting to tingle a little. So that's when I grabbed some latex gloves and put them on, just to - now hastily - finish with what I was cleaning. About 20 seconds later and the gloves had gotten a krinkle-coating like look to them... Now I started to work even FASTER! lol After another 10 seconds, the gloves just started falling apart on my hands as I worked (big sections fell off). 😟 Oh, and that tingling turned into a burning sensation! By then, even though I hadn't completed cleaning the part, I was finished either way! Put the lid back on and went in and washed the hell out of my hands! Which at that point, since I hadn't washed them before putting the gloves on (just dried them with paper towels; dumb), they're turned more pale a color than I'd thought possible! Thankfully, I suffered no ill effects and my hands were back to normal by that night. But not have *those* details have sure stick with me! The less important stuff may not have, but thinking my skin was about to fall off any moment sure has... 😊 That was some potent-ass solvent, that's for sure, _whatever_ the fuck it was! hah _(this was all brought back from the fact the one guy was cleaning the oil pan without gloves on)_

[@Housecat333]

sounds like you were using some HF or sulfuric acid based cleaner. probably meant to be diluted with water

[@DUKE_of_RAMBLE]

@@Housecat333 I could be wrong, but I think most degreasers are solvents (eg: mineral spirits, petroleum distillates) and bases. From what I've recently come across, for greases a basic solution is better than an acidic solution; caustic instead of corrosive. But now I'm kinda curious, so I'll try to track down what I was using... 😁

[@DUKE_of_RAMBLE]

@@Housecat333 Alright, it's *definitely* _"Berryman's Chem-Dip"_ product, no doubt about it! (their Chem Tool fuel system cleaner is the best for 80s/90s vehicles!!) Whether or not it's the same formula as today's, is up for debate, but that's what this Safety Data Sheet info applies to (I genuinely feel like it'll be less potent now), and here's the relevant details: *HEALTH HAZARDS:* Skin Irritant - Category 2 _[2 = "Moderate" severity]_ Eye Irritant - Category 2A *Component* *Weight* Water 40-55% Heterocyclic Amine Derivatives 15-20% 2-(Butoxyethoxy)ethanol 8-15% 2-Butoxyethanol 8-10% Ethoxylated Alkyl Amine 1-5% And the warning about prolonged skin contact, specifically, as it's exactly what I described! *_SHORT-TERM EXPOSURE_* . . . . . . *Skin Contact* defatting of the skin, drying and cracking of the skin, and aggravation of pre-existing skin conditions The "defatting" is the removal of fats and oils, which is what I was describing by my _"hands looking like the longest bath ever, x2"_ heh For a good visual analog: the giant Japanese water salamanders... lol _(except their skin is loose and floppy to increase surface area, allowing them to breathe underwater w/o gills; there more to it but that's the gist)_ Anyways, my suspicion is it's potentially basic (to solve degree), due to that last chemical mentioning "Alkyl"... but in the end... 🤷‍♂️ heh My motivation for Googling this extended as far as to me providing the info that only I knew, which was knowing what the product looked like... ☺️🥴

[@DUKE_of_RAMBLE]

@Shawn 🏴‍☠️ Stafford No, it melted that, too! Kidding. I honestly don't remember _what_ became of my old 'Bird unfortunately. I'm _pretty sure_ the trans blew one day on my way home from work, but I'm not sure why that would've resulted in me getting rid of it... Which makes me think it was the _motor_ that went? 🤔 Yet, a motor grenading is something that would've stuck with me... So 🤷‍♂️ 😕 Was in great condition though. I had GTA snowflake rims and tail lights on it, to. My 93 is the spiritual successor of it though (same color red). Similarly having just about every damn option package available (as per RPO list), but TA 5-spoke rims this time since there wasn't a GTA for 4th Gens. She hangs out in the garage. 😊 (🤔 or was it the 93's trans and the 91's motor _did_ grenade.... as I *did* put a beefed up trans and with mild 2800rpm stall in my 93... gah I can't remember, we'll go with that as it seems more plausible; 91 might've been included in a package deal giveaway to a buddy of my dad's)

@Shawn 🏴‍☠️ Stafford Both of mine were Formulas, I just made them my Po' Boy TA lol Yea, I've... hurt my 93 in the past 😞 Whipped it around at a T intersection and whacked the curb, snapped the axel... 🥴 _BUT_ it's better now, than before! It had 3.23s and the usual clutch posi... I managed to get a brand new rearend from a '99 with 3.42s, Torsen posi _(factory after 98),_ *and* the slightly bigger rear discs (also '98+) as a bonus upgrade. 🤘 And since 93 was still OBD1, my trans wasn't electronic and I just needed a simple plastic gear (like yours) to make the speedo correct again! (whereas OBD2 would've needed an ECM flash to correct for it) But yea, definitely hold onto yours. Reason I bought my 93 was due to missing my 91!

PCV to exhaust and EGR blocked off. You can’t get deposits if you only have air and fuel going past your valves. Regular oil changes and a little bit of thought means you never have to do this.

They could try this: 1. running the engine to temperature with a fresh filter/oil up to 1 hour 2. drain the oil and replace the filter with a fresh one 3. remove engine from vehicle and mount it to a stand 4. fill engine with paint remover used in this episode 5. remove/loosen spark plugs for 0 compression, at which then 6. turn the engine by hand/drill for 1-2 hours while using a heat source to heat the engine block under normal running temperature with heat guns/blow torches. After the time is up, they could completely dismantle the engine after it cools to see the effect and any potential damage to the pistons/rings, cam shafts, cams, and other critical parts. If paint remover could effectively remove nearly all traces of sludge/oil without doing any damage to the engine and it's parts itself, then it could save people a hell of a lot of money. Even evaluating the fresh filter after the cleaning run for any metal shavings could identify a critical issue as well.
