2010 Supercharged Platinum Sequoia

My husband and I bought a 2nd gen supercharged platinum sequoia 3 months ago. 200k miles.
Full carfax of regular dealership maintenance.
Now, I understand anything can happen buying used cars, but it was running great until last week when I took it to a Valvoline to get the oil changed.
Usually I’d go to the dealership or a shop, but we’d recently been burned at our local Toyota, so husband told me just to run it through.
2 days later it starts leaking/spraying oil. Stopped driving it, towed it to a shop, and we are being told engine is blown.
1st question - Are we idiots not knowing, do superchargers need special oil changes?
2nd - Is it worth replacing the engine? Am I crazy for thinking about it?

 

Nothing special even though it's supercharged, you should be able to treat it the same as a stock vehicle and it'll be fine.

Replacing the engine is kind of your call, but won't be cheap and good chance the cost of the engine and labor is more than the truck is worth.


Can you give details of what you mean by spraying/leaking oil? The engine could be blown from running the higher power from the supercharger, and while not unheard of, would be rare even for supercharged trucks. But that's the first explanation that jumps to mind if it visually was spraying oil out? But snother option is the place you went to left the drain plug or filter loose, and the truck leaked oil out and that's what blew the engine, in which case it's firmly their fault but not sure how you'd prove it.

 

No special oil.

My guess is they cracked the oil filter housing causing the engine to run dry. If so, the engine is probably toast. Used engines arent that bad, I would personally just put a good used one in. I mean you already have the supercharger, might as well.

For me it would always better to go a couple of days on old oil than go to a quicky lube shop, that's an expensive lesson.

 

Sounds like it’s the piston rings…

We are just very surprised since it’s supposed to be such a reliable engine.

Anyone know why it would do that? Would it be from really hard use?
The carfax maintenance was very regular and at the dealership.

The shop we have it at told my husband they were pretty shocked when they figured out what the problem was.

 

Where was it leaking spraying oil?
What was the compression for the cylinders?
Which cylinders are effected?
How long was it ran with low/no oil?
There were a few engines that had piston ring failure/ dropped valve etc.
Some detailed info is needed.
I would definitely install another used engine with the supercharger installed. Specific parts will need to be saved from the engine

 

Oil was coming out of the dipstick tube. We’re assuming pressure popped up through there.
Don’t know about cylinders, waiting to hear back from shop on that.
It was not run without oil.

Should we get a second opinion?
Anyone know of a good Toyota specific shop in the Portland, OR area?

 

Just hate seeing posts like this! Hope is gets resolved without to much issue. I would wait to hear what a Toyota certified mechanic has to say. But,,,,,,,,, suspicious minds would be looking at the oil change place! This is why I always take it to a dealer I trust.

 

I would get a second opinion.
Did they even change the oil and filter right?
Did the shop overfill the oil! This would cause major pressure and blow oil out the dipstick.

I'd recheck oil level and drain off if too high, pull all the plugs. Look at the CCV/PCV hoses for oil and intake side of throttle body. Do a quick compression test.
PCV valve stuck?
If I still lived down by Portland I
I would of helped to look it over. Too many places with bad help around.

 

Oil coming out the dipstick and jumping to the engine being totalled or the piston rings failing is insane. I would get a second opinion and do everything @Mdl said.

 

Collapsed oil filter? Wrong type?

I would call Integrity Auto on 122nd or PDX Automotive on Halsey. There is a good shop up here in Vancouver but that might be too far.

 

I’m definitely willing to go to Vancouver.
We have a list of 4-5 shops to call tomorrow in Portland.
Ben’s Japanese Auto, Integrity, PDX Auto, Gary’s Auto, and I think one more.

Definitely hopeful. Especially since my husband said the car had zero symptoms of anything wrong until the engine light turned on in our driveway, my husband turned off the car and opened the hood to find oil leaking.
No white smoke, no rough idling, no power issues, no acceleration problem, no noises, etc.

Thanks SO much all!

 

You should be documenting this. As it clearly seems the oil change shop overfill the oil or messed up on oil filter install. Ensure the shop you bring it to documents the parts in and condition of filter and housing.
Did you at least check the oil level?

Update for anyone interested… engine was indeed toast. We went to Ben’s Auto and had them replace with a used engine.

We are coming to the conclusion that we possibly blundered.. tell me if I’m wrong.
We were not informed that the Supercharger necessitates the use of high octane (91 or higher) fuel.
So we used 87 from the time we bought it.
Reading now, it sounds like that could have ruined the engine.
Can anyone attest to this?

 

Yes. You need to run the engine with high octane to reduce engine knock. If the engine was not run in a high psi usually no knock or issues. You would of heard and known of major pinging and knock issues if you were under high psi boost from the supercharger.

 

Factory they take regular but with the supercharger they require premium fuel.
