Direct injector seals?
https://youtube.com/shorts/uk093vMmA...Z47zsr6crJdqoT
Would this be the direct injector seals? I just had them cleaned (CSG) so I’m inclined to think I messed one up in reinstallation. But, mine sounds like rocks hitting the firewall and examples of the direct injector seal noise sound much louder. Sent from my iPhone using Tapatalk

I would think that bad DI seals would have a more rhythmical and less a mechanical sound. What does it sound like under the hood?

It’s hard to get it to make the sound without a load, so I’ve yet to hear it from under the hood. I do think it’s getting worse, so I guess maybe I’ll be able to hear it while revving without a load soon. Sent from my iPhone using Tapatalk

Yeah, sounds like DI seal.

Gracias. I think it’s gotten worse so I’m going to try to confirm this week with my stethoscope thing. Any advice before I start the job? I put the injectors in, but they were redone by CSG, so I didn’t have to mess with seals last time. Also, I’m pretty sure I screwed something up, because I just put the redone injectors in around mid-June and I’m already having this issue. Sent from my iPhone using Tapatalk

If freezer is good, would dry ice be better? Do you think it could make the seals too brittle?

Nope. I read about that, but they went in pretty easy at room temperature. I’ll do the freezer trick next time. Sent from my iPhone using Tapatalk

It's an extremely delicate operation normally performed with a special tool.

This is where I get confused. Is there a special tool for inserting the assembled injector into the cylinder head? Or are you talking about the SST for installing the seals to the injectors? I had the injectors cleaned and new seals and o-rings installed. I did not install the seal to the injectors. In fact I had all eight cleaned because I ran E85 in the car for about 70k miles. Can you recommend a good video on the process? Without the visual I keep getting confused about what part of the process is being discussed. Sent from my iPhone using Tapatalk

The tool aids installation onto the injector. I see how I wasn't clear about describing that.
