I RUINED IT! Tearing Down A "BAD" 2.0L Chevy Cruze Diesel The Wrong Way

I used to build these cars in Lordstown and I was there when they launched the Turbo diesel. Just a little nugget, the diesel cars came down the line with a red manifest taped to the hood indicating diesel, regular models had a white sheet. Diesel car all received heavier trim pieces, thicker hood pads, thicker firewall padding, thicker padding under the carpet, behind all the trim pieces. and under the rear seat. They also received more body sealer inside the spare tire well from the body shop. I'm pretty sure they also had a thicker head liner. All to help with the extra noise from the diesel.

I think Eric was feeling a lot of remorse for using that impact gun on the valve train. Its okay Eric! Its okay!😀👍

That 5 point fastener means someone is mad they're not designing stuff for Apple.

This engine had a bad waterpump. The waterpump on it was brand new the waterpumps on these engines have a habit of seizing up than the belt will rub against the cover until it snaps. Thas why the rockers were broken. I think they did a timing kit on it to fix it but it didn’t work. This is a common problem of this type of engine what actually is a fiat/alfa romeo engine that gm had the rights to manufacture.

The engine is very normal here in Europe. It is actually designed and build by FIAT. It has a very known problem that kills it. The O-ring between the sump and the oil pump becomes hard and leaky. It sucks in air together with the oil and when the oil light comes on, it's already too late. The bearings on the crank are finished. A known problem in Europe and used engines are sought after and expensive.

To undo the loctited fastener, apply reasonable torque on the edge of stripping and hold the torque. Hold. Hold. Sometimes it can take up to a minute. And all of the sudden it gives. That’s because polymers in the thread locker are pliable. They will resist sharp forces like vibration or impact wrench, but will give at the steady force.

This is a Fiat 2.0 Multjet engine for sure. very good engine indeed. They design the rockers to do that instead bent valves.

Oil pump screws - "manual impact driver" Works great.

I admit I cringed when the impact was spinning the camshaft, but I think it is so cool that you said perhaps it wasn't the best idea, and then admitted it freely as a mistake at the end. It takes courage to admit mistakes in a huge forum like this, and I admire that. But, based on some of the other comments about the water pump seizing (though it didn't seem like it was seized, though the engraving of the timing cover by the timing belt is a sign of that happening) and causing the valve timing to get messed up, the busted rockers (which are apparently a purposefully designed weak-link to prevent bent valves), may not have been your fault. You may have broken a few more rockers in the process, but then, maybe not. I hope you can get some positive ROI on this engine from the good parts. Great video as is usual. Your witty and humorous commentary as well as great information content always assures that when a new video comes out, I'm on it right away. Thank you for doing what you do!

My Vauxhall Insignia have this engine, I really love it, mine done 200k and it's still run amazing with no problems, just regular mentenance, them big issues is oil pickup gasket, they are shit, in time it lose oil pressure and kill it, easy to fix with a aftermarket think, except that it's amazing engine ❤❤❤ Good job Erik, I enjoy your teardowns every week 👍👍

Fun fact, the glow plugs on these engines use a M9x1.0mm thread pitch. Something I learned when I went to try to compression test one. The necessary adapter is something that doesn’t come in most diesel compression test kits.

15:08 Senior Design Engineer at a major OEM here. That fastener decision was likely not engineering, it was Production and/or Procurement. Designers aren't in the business of perpetuating retardation of that type.

I love my 2014 LUZ Cruze. Just reached 100k miles, I can get over 600 miles on a tank of fuel (easy 45 mpg highway) and my best 50 mile average is 59.9 mpg (flat road, no wind, no drafting). I've made it from Detroit to NYC on a single tank of fuel twice, and Detroit to Asheville on one tank more times than I can count. And the added list price was mostly due to the trim package, the gas engine with the same trim was only about $1,500 cheaper. I plan to keep mine until I die.

Yes! Midweek teardown! Always a treat

If I was your insurance provider id make a deal: Go ahead use the torch anywhere you like but don't ever touch that chop saw (with no guard) again!

About that unique fastener. You can't delete emissions stuff if you don't have the tools to take it off. I'm thinking it was on purpose. Who knows.

Ray tore down an engine earlier and now you grace us with a teardown. Its a good day today.

I have this engine in my Alfa Romeo in the UK. I love it - Fiat are known in the business for making good engines. 140hp, 350ish NM of torque, I genuinely drive it like I stole it and still get about 43mpg (nearly 50 american mpg I think?) I have seen around 70mpg at around 70mph on the motorway when driven efficiently (uk mpg so ~78 american mpg) Also low emissions (so tax is very very low at £35 per year, I used to pay £35 per month for a GT86!) The worst part of the car is the gearbox which actually is a GM part. 🇺🇸 😂Cant take much more torque than standard and they all have a bit of a crunch sometimes if you rush 4th-5th.

"there's nothing wrong with this engine" As it vomits rusty water You sir are a professional used car salesman

hey eric, just a quick heads up, there's plenty of euro diesel engines where the cams are hollow and the lobes pressed on and to avoid certain issues they make it so if out of time or similar event will break all the cam lifters in half instead of bending any valve since they are just straight up and down (vw, peugeot, renault, fiat, benz, even hyundai and kia diesel's are like that), so yes, the needle bearings are indeed your aftermath in the pan 😂 a few examples would be peugeot's 1.6 dv6, fiat's 2.0 multijet (of which this engine is born from) and renault's 1.9L FQM diesel all have a "cam on valve cover" in a similar fashion to the "cam tower" you find in other engines (like that toyota 2.5L and the GM 3L LM2) EDIT: in my opinion? this engine is freaking mint, she just needs a service and its basically a 100% builders engine! my guess is that it might had ingested water or hell maybe a flood car...
