GM 2.0T vacuum pump carnage plus some heavy varnish

[wwillson]

This engine was sitting on the floor at my friend's shop. The CEL (check engine light) was on for a long time before they noticed some strange noises and rough running. The vacuum pump had failed, which triggered the CEL, but they ignored it for a few weeks. Bad mistake. The vacuum pump finally grenaded, which ruined the cam, caused the cam to slip timing, and ruined the motor. My friend does quite a few of these GM vacuum pumps, as they are a bad design and tend to fail. The owner ordered a new engine from GM, which was way expensive. The job with the new motor and labor is $9k. The owner also neglected doing oil changes and you can see lots of varnish and some sludge. The last picture is a shot down the intake running looking at the build-up on the intake valves, this is a direct injection engine. This much build-up in 70,000 miles.

In the next bay over was a Honda Odyssey, which was sludged badly and was using oil, lots of oil. Another victim of the owner neglecting to do oil changes.

Where is that puke emoji.

I was about to comment that I don’t see how they could have ignored it too long, CEL or not, that would affect the brakes. Looking at the pics made me come to my senses and realize that the owner didn’t have a problem with ignoring things.

These people should have their driver‘s license revoked.

They’ll still drive anyway. Public transit is a joke in the US, and that’s all I’ll say.

I’ve even harped to my enemies that even taking your car to Jiffy Lube is still vastly better than doing nothing.

And now, I can see why Toyota wants the vacuum pump replaced every 60K on the 2GR-FKS 3.5L GDI V6 and possibly the new A25A-FKS/M20A-FKS in the new CorCamRAV and the V35A-FTS in the new Tundra/Sequoia/Lexus LS500 and LX600.

Classic BITOG porn, we love it.

You spend your hard earned cash on an expensive car, then you proceed to kill it. All you had to do was drive trhough Jiffy Lube or bring it over to me for a lousy oil change service. Sheesh.

Really? Their money to waste. Doing their part to keep the economy going.

In the Bay Area, I would have told them to get a bus pass for AC Transit/Muni/VTA or UberOne/Lyft Ride Pass or a gift card to Mike’s Bikes and tell them you should never own a car again.

It is a crime against the vehicle gods.

Mikes Bikes is too expensive. Buy a Tesla instead.

Very true. Teslas still have fluids(brake fluid, Dexron-VI ATF, G-48 coolant and washer fluid). But, they don’t need frequent servicing.

Manufacturers did everything to get away from vacuum pumps on diesels.....It's like they forgot how unreliable they are?

IMO, Toyota more than likely went to a vacuum pump for the brake system - they could’ve used a electrohydraulic booster instead.

Firestone, Pep Boys, Big O and dealership service departments need a raison d’être to stay in business.

That's too bad to see a decent motor shut down for good over simple maintenance neglect.

 

[ElectroMechanoMan]

The average person has absolutely no clue as to why a knowledgeable person does maintenance the way they do. I see it just the way the tech school grads we picked up work in my shop. They have to be taught everything up to and including how to correctly use the tools they are issued. This isn’t because of lack of intelligence. They weren’t exposed to maintenance work as they grew up as all of us country kids were. I was a 3000 mi oil change guy because my dad taught me how to do it, along with points, plugs, and an occasional tire change. You also knew WHY you do the work.

I have done a few of those vac pumps as well. They are also on the 1.5T motors. Terrible design. I just replaced a 1.5T motor with a new reman from Autozone (NuTech motor) with a 4yr warranty. It was 3299 my shop price vs a used 90k mile LKQ motor for 3100.
