Hello everyone,

I recently purchased a second-hand 2009 Nissan D22 Frontier ST-R (2.5 CR, manufactured in August 2009). I’ve noticed it’s leaking quite heavily from the first injector. From what I’ve read, this issue is likely due to faulty injector seals. I plan to replace the seals, but I was wondering if there’s anything else I should address while I’m at it.


Additionally, I’ve read that for models manufactured after August 2008, the injector seals are integrated into the rocker cover. This means I’ll likely need to replace the rocker cover as well.


If anyone could help by providing a list of other things I should check or replace during this process, I’d really appreciate it.

Cheers!
