The check engine light on our family people mover (2015 Toyota Sienna, just over 200K) came on last week.
Took it into the shop to diagnose and it was giving multiple cylinder misfire codes. They changed out the spark plugs and ignition coils, but the issue remained.
Now the bad news... they did a compression test and one cylinder doesn't build pressure at all. They did a leakdown test and they said it sounds like valve(s) doesn't close properly and the pressure leaks back in the valve intake.
How the heck could this happen suddenly? WTF
From there, they said they could proceed to remove the valve cover to check the header/rings to further diagnose, but suggested at that point, you'd be looking at either re-building or replacing the engine.  . They quoted me around $12K all-in for a used engine.
I towed it to my house and I'm currently considering options.
Looking at getting a 2nd opinion on the repair.
If anyone knows a good Toyota engine shop, let me know.
What type of low-ball offer would a dealership give me on the van "as-is"? $1000?  |
If I may ask how often would you perform oil and filter changes on the engine? A lot of the more modern cars, including Toyota's are going with these insanely long oil change intervals which just are not good. There is a whole host of problems from going 10-15k km's between oil changes.
For future reference regardless of what car you have, always advisable to increase the fluid change intervals for things like transmission, coolant, engine oil etc.
Fingers crossed it's not the worst case scenario but if it is and you decide to move on, don't sell it to a dealership. You could get way more money selling it for parts if you wanted to do a little basic work. There is a huge parts shortage now and a lot of people with a similar Toyota are having trouble getting parts for minor accidents. Selling basic things like seats, wheels/tires/doors/transmission could net you thousands.
Good luck! A great youtube channel for Toyota owners from a Master Tech who is incredible and knowledgeable is

He straight up talks about the disaster that is happening with these longer oil change intervals and other corporate made up maintenance garbage. The suits and executives are overriding the engineers and regular working class people are paying the price.
