I tear down at least one bad, blown or core engine every week and have been doing so for the last 3 years. Here are a few of my favorites:
Bentley/Rolls 6.75litre V8 • BROKEN BENTLEY / ROLLS ROYCE 6 ¾ L-Se...
2020 Silverado 3.0 Duramax • BAD 2020 Silverado 3.0 Duramax LM2 En...
Toyota Prius Massive Carnage • BLEW UP A PRIUS?! 2010+ Toyota Prius ...
Infiniti 3.0 VR30DDTT No maintenance Ever? • 60K Miles on 1 Oil Change!?! Infiniti...
Today's engine is one that has been often asked for, a Fiat/Dodge/Alfa Multi-air! This is the 1.4L Non-turbo engine from a 2017 Fiat 500 POP with just 125k miles. These engines can suffer from multiple different failure modes but I was NOT expecting to find this. This was the first Multiair teardown on the channel and the first one I've worked on beyond removing the multi air unit itself.
Why am I doing this? My name is Eric and I own/run a full service auto recycling business called Importapart. Part of our model includes dismantling core, blown and bad engines to salvage the good parts from. We do not rebuild or repair engines, merely supply parts to those who do.
I hope you enjoyed this video! I love all of the comments, feedback and even the criticism. Catch you on the next one!

14:05 “whoever’s idea this was, I hope you get gout…twice” This is the first time I’ve ever heard someone curse someone else to get, specifically, gout

As a retired mechanic, I always enjoy watching your engine autopsies.

I couldn't count how many multiair cars we have had towed in to our shop that quit running.... put some oil in em, crank em a bit... boom running and driving again. Best thing I can say for that design, it protects the engine from lack of oil, becuase it won't run without it😅
-
You could've hurt yourself trying to turn this engine over. I really appreciate you putting yourself at risk like that for our entertainment.

75 year old, English codger here, Eric…….. I love watching your strip down videos……. Your humour and editing is superb…….. Thanks for the fun and education……..

For a cheap engine, I was impressed by how, minus the hose, well it looked, and no Funny parts! Not Fiat fan, but still impressed.
-
Oh hell yeah! Thank you for listening! Keep looking for the 1.4T version!
-
Your videos are always on point, keep it going

These are shockingly very reliable engines if you just change the oil every 5-6k miles, do plugs at recommended intervals, and do the timing belt services.

5:10 - In Europe we outsmarted the FCA engineers by cutting that stupid tab. LOL

Next week is a 5HP Briggs and Stratton lawn mower engine. Can't wait!

I had one of these engines for years in a Fiat 500 Pop. Amazingly easy to work on and care for with basic knowledge and tools. Oil changes every 5k, spark plugs every 30k, timing belt every 150k. A full set of plugs cost about $15. Bought the car for cash, drove up to 170k miles, then sold it for more then I bought it for to someone who's kid killed it within a week.

100 horsepower? I learned to drive in a ‘57 Volkswagen. It had an entire 36 horsepower hooked up to a 4 speed stick shift transaxle. My dad had it up to 70 mph on the highway. It finally rusted out.

I loved the line " I hope whoever designed this gets gout ..twice " 😅👍

One of my coworkers worked at Fiat/Alfa for 5 years. He told me some guys there just cut the intake bracket and 2K glue it back together to save time 😂
-
it wouldn't have been an oil related failure because if there is not enough oil in it the multi air system goes first and throws an engine failure before the engine even have a chance of killing itself.

My hypothesis: Owners thought that if you do enough oil changes, you do not need to do any other maintenance like plug replacement, timing belts, coolant (corrosion in the coolant system). As a result cyl. 1 dropped the spark plug core, fragments blew back in the inlet and made their way into cyl. 2 and even 3. The 40.000KM plug interval is for the cheap plugs, not for the platinum/iridium ones. Depending on the state of the rest of the car, I might have put new plugs in and tested how it would run and how much oil consumption it would have. If the piston rings weren't damaged and the valve seats survived it might be good enough to keep it going. 101HP naturally aspirated and port injected would not be too critical for the shape and surface of the combustion chamber so I wouldn't be too worried about engine knock. For the cost of four plugs and maybe 30 minutes of labor it would be something I'd take a gamble on.

Dude seriously, this channel is better than anything on Netflix!

You aren't old enough to remember, but back in the leaded gas days I used to change plugs, points, and plug wires every 20K on my American cars, mostly GMs.
