SLUDGED To Death: Tearing Down My SEIZED Audi 3.0T Engine

The engine out of my 2011 Audi A6 has been lurking in the shop for awhile now. I decided is was time to tear it down and figure out what caused it to seize up in the car. I expected it was a headgasket issue as the exhaust was full of coolant when we pulled it apart. As I tore the engine down it seemed like there was no issue with the headgasket. All I found was sludge, and it only got worse as we went, the oil looked like jello in the oil passages. The sludge was so bad it caused the engine to seize.

This is why regular oil changes are so necessary. Audi's long life service intervals seem to be a joke. Interesting teardown. Good job.

@michaelbenoit248 2 года назад

Mercedes has a 20k oil change interval. Then 15k for the Mercedes Diesel 3.0 TDI vans that should be 5k max because of severe use & having a DPF.

@SteveBassen 2 года назад

Long OCI's ruin everything, 5k should be a standard, especially for modern engines with specialized cylinder coatings, lots of chain tensioners, etc.

@@michaelbenoit248 My 2018 E Class diesel just went through it's 30,000 kilometer (20,000 miles) service - Third oil change. Engine computer tells me next oil change is due in 25,000 kilometers. Dealership service advisor told me to ignore that - change every 8,000 kilometers (5K miles). DPF regen system changeout in my model will run near $8,000 to fix if it goes faulty.

@DarinNederhoff Год назад

LOL, honestly this isn't a bad engine to work on compared to many others. You can pull the supercharger off the car in under an hour. When we bought ours a friend and I went ahead and replaced the PCV, water pump, thermostat and supercharger oil along with a couple of the plastic coolant pipes under the charger. Honestly no big deal. I suspect it's scary for those that never ventured outside of the pushrod engine realm. The only job I cringe about on this engine would be a timing chain replacement but they are not super common when you keep up on oil changes (no 10k intervals).

@quattro4944 26 дней назад

Agree with you most of the stuff from the top is not that hard to do even SC come off in less then 20min if you know which hoses and vacum on the back undo , and you don’t need for sure to pull engine out to do pretty much anything except timing chains that you mention , similiar to you I’ve done pcv,water pump , thermostat, pulleys ,and other stuff , also like you mention do oul cgange intervals shorter thean 10k and you will be fine , the most common issue is upper chain tensioners that rattle on the start but i got mine 4yrs now and not get worst at all , as long as you chang oil should be fine .

@emmanuellopez5037 17 дней назад

I just ordered the supercharger intercooler replacement kit for my Q7 because last time I took the sc off to do the pvc, thermostat, water pump, intake runner valves ect. I noticed what looked like coolent build up on the runners on cylinder 2 and 3 and clean spots on my sc intercooler so before I get major malfunction I'm going to change them. I definitely love working on this engine but I wish I had access to a lift so I could drop the engine and do the guides and chain replacement.

@yamaman6882 2 года назад

The gearhead in me enjoyed watching this engine tear down. I agree Audi has one of the worst engine designs to work on. Maybe the factory designed the engine to be so complicated so any major engine work would be so labor cost prohibitive that it be easier and maybe cheaper to just buy a new engine.

@jamesmedina2062 2 года назад

Audi is same as VW and Porsche and Lamborghini so within VAG there is lots of talent. Every engine is different and even the markets dictate different designs. You should always know what engine you are getting and what it costs to maintain it.

@drewsshoplife 2 года назад

The intercoolers fail on these engines quite often which wound cause coolant in the exhaust. The pcv housing cracks too which will cause coolant in the oil. These are amazing engines but do require major preventative maintenance.

@pablotejadasantos7553 2 года назад

@Zx11pilot 2 года назад

I did the thermostat, water pump, serpentine belts, pulleys, and the supercharger service on my 2013 S5 and it really wasn't bad at all. No issues doing any of it with the engine in the car. Once you put the car in to service position there is plenty of room to work. Takes a bit of patience though :)

If I had to take guesses, not a surprise it was a some failure in some collant line inside the supercharger. Entering collant into the combustion chambers through the intake, and then gradually mixing with the oil. Ending up seizing the engine.

@thadb9684 Год назад

Owned an a6 with this engine, while it Is a hassle to do any work you can still do it with the engine in the car. The pcv value is the black thing right at the bottom of that valley, had to replace that and it took someone who had never worked on cars before about 18 man hours 😅 also decided to do a few more things like get the injectors cleaned and flow matched while I was in there.

@thadb9684 Год назад

Also don’t really like how you’re portraying it, if you take time and realize all the connectors that you are breaking ‘because they got so hot’ have buttons to release them. And imo, for a 3 liter it can make enough power to make up for its losses, but seriously if a 16 year old can do the maintenance it can’t be that hard.

@WatchJRGo Год назад

I'm am the absolute king of connectors, literally everyone I work with lets me pull the harness because I never break connectors. If they break they're trash, I released every single one. The plastics aren't designed to hold up to that heat, if I was fixing it I'd get out my tools and re-pin every connector with factory housings.
