Can This Audi Engine Be SAVED? Coolant Mixing into Oil

Oil mixing with coolant is normally a head gasket. This Audi engine wasn't a bad head gasket, but still had oil and coolant mixing issues. This video we flush the engine oil in an attempt to save the engine. The best repair for coolant in the oil is a full engine teardown to check/replace bearings. This car is NOT WORTH THAT!

"Better call Paul" - pretty catchy. He should use that as a slogan. :) And - btw. - I'd have done exactly as you did, C. I would perhaps, just out of curiosity, send the last flush sample to be analyzed too see how much coolant remained - if any.

[@kennethd7048]

Ok Charles, here's one for ya. 2006 Honda Ridgeline. The oil cooler/ radiator cracked and antifreeze into the oil. Replaced radiator..So, the system was drained and we added water and a dawn dish washing liquid, did that eight times cooling system .. obviously and a few oil changes with sea foam and refilled with factory authorized VW coolant (kidding) and sent it..i understand that this is Audi VW show but guess what.. the pistons go up and down, the wheels go round and round... you're a good teacher by the way. I wonder if there is a way known to man to re-engineer the pcv system on that engine?

[@JoeyGLI]

That ending where you cut the see right before was beautiful 🤣

[@PapaJMemphis]

Charles, you just broke my world! I've done probably 15-20 oil changes with LiquiMoly and I never realized there was an oil change sticker ON THE BOTTLE. I'm so mad at myself for never noticing this. How could you do this to me?

[@Fastboi69420]

Huh I never noticed either. But I do 5k intervals on my ‘19R so it’s hard to keep track… unfortunately my alternator last month failed 1000 miles out of warranty, and it gave my its first epc & cel last week… suspecting injectors 🤦‍♂️ I also went eqt stage 1 right after my warranty ended so no chance of getting either of those covered anymore…

[@CallMeDezy]

You could have easily keep the flush for an hour or so and rev it up to around 3000rpm for 20-30 seconds every once in a while, I usually do that when changing the engine oil and it may clean the engine better than just 10 minutes of idling. There are also "long life" engine flushes available where you can drive a car reasonably for 30-50 kilometres before replacing the oil, that would've been great for this particular engine imo.

[@TooBlessedToStress88]

Liquimoly states to idle and not rev or drive. You don’t want the crude being knocked off to circulate at a elevated rpm to score the internal as the crap coming off is abrasive. Keep wrenching my friend.

[@CallMeDezy]

@@TooBlessedToStress88 yeah Archoil states NOT to drive your car, yet their technician says you can drive no worries for around 50km, it's just a fail safe for the company

[@TTAutowerks94]

Awesome video yet again from the one and only Humble mechanic 👌 Reminds me or how I like to treat the inside of my engine and customer's when servicing, I'll always change oil first before using a flush (if the engine oil is too old or feels physically garbage) Then it's the safest way to thoroughly flush the engine without much risk of further damage.. Liqui MOLY for the win 💪 I use their flush, conditioner and fuel treatments, I also use LUCAS oil treatments and BG products 👌 Love the attention to detail in all your videos thankyou for the content Much 💜 from the UK

[@elev8j10]

Milkshake is not what you want to see in an audi. I picked up a B6 A4 1.8t 5 speed with some good performance goodies that had a blown timing belt for super cheap. Made the mistake of getting a "tested" head on ebay. When got it I knew I should have taken it to the machine shop to test it all myself instead of just believing this place but I didn't. Ran great but after it got warmed up oil and coolant mixed very quickly. I thought maybe it was possibly my doing so I did it all over again triple checking everything with a better brand head gasket. Same thing. When it got warmed up... boom immediate mixture. Finally took it in to the machine shop and of course cyclinder 3 on the head had a crack and when it got warm it was expanding and mixing. I was pretty upset to say the least. It's a good thing I was constantly checking oil and I caught everything quick. With a proper rebuilt head and a few flushes it was good to go. But you just know even running 30 sec with coolant in it has some consequences. I'd say it just depends how long he was driving it after that coolant light hit. Awesome how a failed pvc can lead to total engine failure. Way to be Audi.

[@adriannp.]

1.9 tdi PD. This engine got me mad years ago (and still), the fker mixed drop by drop the oil in the coolant system passing throught the head gasket, the coolant was fine but after some months the coolant looks really bad. What a pain in the ass, amazing engine, amazing troubles...

Of course it was the right course of action what you did. No need for opening up an engine if that process fixes it and it was the pcv that caused all of this..

[@francisdiy1]

An alternative I learned from growing up on the farm fill the engine all the way up with diesel instead of oil and leave the cap open overnight and Then drain it What I mean by all the way up is literally all the way up to the cap and do not start the engine like that

[@Nipplator99999999999]

I will say short answer is yes you can save it...but long answer is if a gasket or a designed point of failure like a freeze plug it is not very terrible, but it is not always the go-to failure and then you have to ask yourself... "I believe I have the willpower to do this, but does my bank account?" Is it worth it again?

Every brand has their unique Engineering difficulty... -Mopar has weak output shaft housings and suicidal clutch discs. -GM is so aesthetically conscious that you can't get to anything to fix it and even if you can it will require 6 different sizes of sockets -Jeep has terrible transfer case joints and weak electrical systems -Ford require a special tool in order to scratch yourself and last for a long time but when it starts to break, it is not going to stop for a while. And so on... German engineers are a whole new level of special people and will find a way to get a 10 min $20 job to take 4 days and cost a grand.

Since then no oil usage, just the cooler went bad in 2020. Now the car has 190,000km & it is running perfect. Would you sell the car or keep it for another 200,000km?

[@propm]

Well, I did not have this specific issue, but I got a low oil pressure on my Audi A4 2.0 TFSI four days after I bought it, that was a bummer, and I was so close to my house and decided to drive the last few hundred meters, lucky only the turbo died, and judging by the amount of oil in the intercooler it was already in bad shape so I guess it's not a big deal. but yeah, the oil pickup was full of gunk causing the low oil pressure. It was a pain in the as to take off the oil pan, I had never struggled so hard taking an oil pan off a car before. It's up and running now and I been driving it for a few months, but it had 273K Kilometers on it and I did not pull the whole engine apart, I just put a new turbo on and tried it. But it uses a lot of oil, both before and after the turbo change. I don't know if flushing can help with that.

[@rotorblade9508]

the manufacturer could add a sensor to the oil pan that can tell if there is water in oil. Basically water conducts electricity so if you measure reduce resistance between two electrodes at cold start it means water in the oil pan. the thing is by the time risk of a failed head gasket starts to increase the car is already too old and manufacturer would like you to buy a new car.
