100% DI Failure with Nurburgring rentals

[whataboutbob]

I've got 32k+ on the car with 100ish miles of daily commuting and 2-3 2day AutoX events per month. I just SC'd my car. It seems to run great at this point. I'd like to check my injectors for signs of issues, but what am I looking for?

NM, a bit of searching seems to have found more info.

Since I have gotten the car back I haven't had any issues but I am still wondering if I am getting the full story.

Has anyone else had this issue?

A bad plug is a bad plug, switching cylinders couldn't have done a thing. Take your car up a hard pull over 5k rpm in 3rd gear and report back.

So you are accusing the OPer of hearsay, classy. How about utilizing the forums as a means to help correct the issue before it leaves a lot more dissatisfied customers instead of pointing fingers and hiding in denial? Something constructive maybe ?

You prove it. You are the one claiming its a problem, not me. You own a car, pull yours.

I'm accusing you of quoting other people's post as fact. You even quoted that they are dropping the 86 from their fleet based on reading another persons post. Yet the cars are still offered for rent. I am not questioning the OPs talk with the employee.. But that doesn't make it fact does it? You don't really know the facts.. Yet you are determined to spread the word.
I'm sure Toyota/Subaru will address the issue. They have a bit more experience at this than you I suspect. In the meantime.. I will continue to enjoy my car and get it fixed if it breaks.

Don't bother me with the truth, my mind's made up!

You are a perfect candidate to help the community. Study the manual, you need an o-ring tool which isn't expensive but hard to obtain right now with all the issues. Also parts are reported unobtainable for several months back-ordered since the issue is so widespread. So plan ahead.

Thanks

This is what you don't want (on the right):

When I pulled the injectors/fuel rail/etc off for the Innovate SC install, none of my injectors looked like the one on the right. They all looked like the one on the left.

I doubt you pulled the direct injectors to install your supercharger.

My bad. Yeah those were the port injectors.

I don't think that's the right answer. Do you really want a replacement engine, or a car with a poor rep and resale value?

There are basically three scenarios with brand new engine design catastrophic failures:

1. The OEM takes care of the issue and fixes the root cause that arise whether it be <5% or 50%

2. The OEM covers the <5% under warranty waits a few MY's for a redesign, after warranty with the initial design the issue festers and presents itself in more and more cases as miles pile on. Word gets out and resale plummets

3. The enthusiasts of the community put their collective heads together and come up with a fix that the OEM can't due to economic, corp. politics, or regulatory reasons

4. The engine was well or over engineered to the point that it gets a reputation for being "bullet" proof which helps resale and in general success of the platform.


Threads here are littered with reports of blown engines first and second hand, and lets face it this forum is but a small percentage owners. This problem is not traceable to a certain build date or bad batch. It has been acknowledged by on small division of Toyota for months yet nothing has been done. Dealers can't get parts due to so many cases. At this point Toyota is choosing #2, we need start working on #3.

@regal we think good information will come from those who inspect their direct injectors even if they're not experiencing engine problems. There may be many people on the road to premature failures who do not yet realize it.

It never hurts to check, right? Everyone can learn from it.

From memory, I thought there was a thread here describing a running change in the DI system to address this last year, but couldn't find it. Anyone else remember this?

@DriftEm hey buddy i was at the sdrc last week just checking out the track and bump into Charlie and said that your car sounds like it was miss firing.. could you be have this DI issues ? hows your car running? i know you drive like you stole it

[denkigrve]

@BlaineWasHere is already at over 30k with a ton of autox abuse. He just popped an axle recently. No DI issues though.
