New Lexus LS will have a twin turbo 3.5 litre V6

I am very aware Toyota made a truck with a turbo, my fiend had one. People always thought he put a "turbo" sticker on the tailgate. Don't remember them people too popular and of course they stoped producing them. When they mass produce a good thing you will always be able to get one and aftermarket parts far into the future.

 

They sure did.

They were the most unreliable engine you could get in a toyota truck as well. And I'm including the 3vze in this opinion.

 

Come on now, the 3vze wasn't bad, if you didn't mind changing the head gaskets every other oil change...lol

 

I never once had a problem with my 3vze, other than the low power. 22rte was known for cracking heads.

The head gasket issue was huge once they went to the non-asbestos HG's. The early trucks were fine.

But honestly i see alot of 200k+ mile 3vze's on the road. How much of that do you see from other manufacturers.

 

Hmm I've ran turbo's far past 100,000 miles on many Diesel trucks. I get your point but really a modern gas engine like the 2GR isn't rated for any longer then that. My father in law has a Venza with a diagnosed rough idle which is why he's trading it off on a Bolt.

You won't get an argument from me on the oil part though. All of the Ecoboost vehicles I've owned or oversaw I've used Pennzoil synthetic on and I've never had an issue with the turbos before 150K. The youngest truck I've paid for a turbo on was almost a decade oil with 500K on it. It's not a lot of fun when a Turbo goes on a Navistar engine.

I have seen valve timing system issues after 120K plenty of times though from different manufacturers. Usually when people again use crummy oil. It plugs up the mechanisms that allow for the valve timing changes and that leads to some of the weirdest noises you will ever hear out of an engine.

 

My experience with a 3VZE in a 2-door 4-runner was laughable. It was my best friends truck, and he had to replace the head gaskets 3 times on it. Also blew the lower end on it twice before swapping in a 22R. Before you say it was lack of knowledge/experience, he is a mechanic, and even sent the heads out each time for machining. It's possible he just got a bad one, but that engine sounded mean when it screamed on the trails in the mud pits

 

How many trucks get pulled off the road because of engine issues? Almost none. It's usually a recurring front end or driveline problem that kills them. Heck, up here its way more likely that a frame will rust out then it is that an engine will fail. Still plenty of those truck engines pulled out of, well just about any model, sitting on stands hooked to a water pump running natural gas to power an irrigation pivot. The farmer favorite seems to be the old Ford 302 or GM 350. A few have used Toyota engines with mixed results.

I can't think of a modern truck engine that was a walking disaster. Maybe the Atlas series from GM but even those engines were a lot better after the first year.

 

ummmm no.

 

4.6 / 5.4 Ford Mod motors.

They loved to shoot sparkplugs out.

Agreed on the rusted frames.

350's/302's are solid.

 

You may want to try elaborating.

One of the nicest features about the Fords is their low end torque. There's an FTL shootout somewhere between a 5.3 L GM and a 2.7 L Ecoboost Ford somewhere out there that shows this nicely. The 5.3 L is rated for more torque and HP but doesn't make 80% of it until 3500 rpm. The Ford does so far lower and it shows in towing and driving tests.

To be clear, boosted engines are not a god send. They do have more parts and more maintenance from a strictly engineering point of view. However in the world of CAFE and mpg dictation by the government, turbos are a good option to keep torque up and meet regulatory requirements.

 

Yeah the fist 5.4's were brutal for that lol. It wasn't every truck like people made it out to be but definitely enough to piss you off. Luckily the 5.0 L corrected basically all of those issues including the VVT ones.

 

Here's the test I'm talking about. FTL did the real life which matched these results as well. This is all on a dyno obviously:

It's a good comparison of what well sized turbo engines can do over their NA counterparts. GM also can't seem to get that high end down to the wheels for whatever reason.

 

That also was not a catastrophic engine failure though, a pain in the ass to have happen yes! The correction was heli-coils and a different style plug.

 

How many mechanics do you trust enough to do a heli-coil on a sparkplug hole deep inside a head?

 

Ford actually paid to have the lead tech at the local dealer do this to a few trucks at the last place I worked. From my understanding Ford designed a kit just to fix this and issued them to every dealer. We also knew the owner well and he ended up offering to take those trucks in on the newer 5.4 L, they changed the design in the mid 2000's, and the problem disappeared.

It happened twice out of a fleet of about 20 or so Ford trucks we owned at that point. It wasn't happening on every truck. It didn't happen right away either, it took years. It was just common enough to be well known as an issue.

 

It happened to my cousin's Lightning a few times when he owned it for a year. He traded it in on a ranger before the winter, LOL.

 

LOL. Yeah we didn't own Fords when this was first an issue. I was talking around 2004 when this happened to us. I think the new engine top end came out around 2006 and that's when it went away.

The funny part is that the first time it happened the summer student driver of the truck didn't have any clue what happened. He drove the truck back to our shop and was concerned about the check engine lol. It wasn't until our in house mechanic took a look that we sent him over to Ford, again on his own power. The second time was way funnier though. My dad was driving the shop truck and it put a spark plug almost clear through the hood. The metal was torn but the plug didn't have the gas I guess to get all the way though. Still scared the shit out of him lol.

Lots of those late 90's early 2000's engines had weird issues like that. I blew two cylinders out of a 327 2001 GM truck lol. It still ran because the block was intact . Lots of Ram guys have similar stories about the 5.9 L blowing itself to bits, obviously you don't drive away from that.

 

Oh hai guys I heard Toyota is offering up a diesel next month. A guy I know who has a brother who has a cousin whose sister works for a neighbor of a Toyota employee said so.
