Ha... no explanation needed. We have a First Amendment for a reason so exercise it often—especially when working on these engines.
On a side note, I'm surprised that the seal height isn't greater (say, 0.5mm, for example) and uses the angle in the collar as a mechanical wedge. There must be a reason why the injector masts have an angle rather than a shelf. I guess I need to see one of these in person to get a better insight on the design. |

I find myself looking at the top of the opening (base of the injector solenoid) with that nice big wedge shape and wondering if some ambitious engineer couldn't come up with a secondary seal that would fit in there as a backup.

Thanks for this man, i just got my car back for a second DI seal replacement since i got a code even after toyota replaced the engine. I really hope there is a permanent solution for this. Btw when my engine blew i had no popping noise other than a check engine light and the car going into limp mode and misfiring, i never had a popping noise of any kind until it actually failed.

Just now watching the video. Very informative. I expected this to be quite in depth but this is a step or two higher than what I expected.
"according to the manual, you don't want to fuck this step up". I couldn't stop laughing at this for some reason. People should watch this for at least for entertainment value even if they never plan to replace the seals themselves. Edit: Just finished, I never even considered an improper installation from the factory. Obviously this must be an automated process which would lead one to wonder what percentage of direct injectors are built/sealed correctly. Also, as for the bevel, my instinct would tell me that a bevel that is made with small tolerances with respect to the seal, would be beneficial in keeping the seal in place, no? The video contradicts this and I'm sure my thinking is likely to be wrong since I don't know the second thing about DI and I only play an engineer on tv.

Motiv catted test pipe and invidia N1, not really loud. My last issue that happened i only noticed it because i got a code no other symptoms really.
Nope just injector Quote:
Injector #3 this time last time it was #2 that caused the engine to die. Im guessing the seals were worn and since they did not replace them last time they finally failed. I got the code during a WOT for merging on to a highway from 4000-5000 rpms but really no symptoms other than a misfire and air & fuel ratio imbalance code, my new engine is not even broken in how sad.

First of all, thanks for taking the time to do this.
Were you experiencing DI issues and decided to replace the injectors, or was this just something you wanted to do? |
