Great work Johann and a pleasure to watch as always.. Regarding the new blue injector caps, they do indeed work fine even though they will sit higher than the injector tip unlike the original green caps that sits flush. When I rebuilt my injectors I had the same concerns and wondered if they taller blue caps would interfere with the spray pattern, but since the originals broke when removing them, I had no choice but to install the blue caps before taking the injectors to a shop for ultrasonic clean and flow testing. And they worked 100% fine with the blue caps with no interference to spray pattern at all. In fact there was only 1% difference between the four injectors, so as good as new basically.
I did, but this was a case of picking my battles. 968 injectors are NLA and I did not want to risk sending them to a company by mail and it getting lost. No one offers a while you wait service, so the risk is in my opinion not worth the reward. I have now drained the tank and replaced all filters and will do a first fill with synthetic fuel which should help clean the injectors in situ.
Brilliant job you are doing much respect
Thank you Gregg!
Engine is looking awesome, can’t wait to see it start 👍
You and me both! And then I can move on to the suspension 😎
As always, well done.
Thanks again!
Beautiful work!
Thank you very much!
Please keep it going, Johann, on the 968. I have some items to do on my 944S that you are currently covering.
Thank you John, happy to help!

Thanks for the tip Alex, I was thinking exactly that; that they would ruin the spray pattern. Good to know that they don't!
Jon, this is great stuff! Did you consider sending the injectors out to get fully cleaned and flow tested?
