Default AVCS Driver side Banjo bolt install/Screen Removal

So I just got my engine back from the machine shop and the builder left off the lines that run to the AVCS modules on the top side of the engine. He mentioned he did so because he wasn't sure whether or not I wanted to remove the filter screens from the banjo bolts. By doing so he left me in a bit of a predicament because now I can't get the bottom bolt reinstalled on the driver side to re-attach the lines (he put the cam gears in and set the timing). My guess is the only correct way to re-install the line and banjo bolt would be to remove the cam gears and just redo the timing? Also should I just remove the screens from the banjo bolts going to the AVCS to avoid future problems as the one screen is installed on that lower bolt that sits behind the timing cover and is generally inaccessible for cleaning if it were to ever clog? I've researched it and there seems to be mixed feelings about those screens but the consensus seems to be eventually they become an issue.

Thanks for any suggestions!

Regular oil changes help extend the life, but I was talked into removing them by my first tuner and I did find it to be a bit of a peace of mind.

Yea I'm thinking of just pulling em... I was trying to figure if there is a way to re-attach that driver side line without pulling the cam gear again. It would save a lot of time if I didn't have to remove and re-install the driver side cam gears and re-do the timing belt.

I would pull it. My tuner doesn't run them and suggests no one else do it either.

As long as you change your oil fairly frequently, and run OEM or better oil filters, you'll be fine.

Any ideas on getting the line behind the cam gear re-installed without pulling the cam gears on that side? I saw some people will hack up the cover but I really don't want to do that. Also would there be any issues with metal shavings and break-in with that filter removed?

It happened to me quite recently. I simply forgotten to install oil line before installing cam gears and doing timing. If I remember correctly I had to remove only intake gear to get access to banjo bolt.

After first two oil changes on brand new engine, banjo filter was super clean. But I removed it anyway.

Yea I was thinking I can probably get to it if I just remove the intake cam gear. I'm also probably just gonna remove the screens as I guess worst case is you might get some metal shavings in one of the AVCS solenoids and have to replace it but that's still cheaper than replacing an entire head or a busted turbo. Also is there a trick to re-torqueing that cam gear after you put it back on? I know to re-time the engine you need the special cam gear locking bracket but not sure how you torque it back down and keep it from moving... guess I can YouTubes it!

Most people would pull the timing off and install the banjo that way, I happened to have this issue once before and I was able to put pressure on the rear timing cover and slide everything into place without touching any of the timing components again. The only stressful moment was trying to ensure the threads didn't get crossed up sense you have zero space to work with. But I made it happen on my car and would do it again if in the same position.

Good luck.

Run the filters until engine is broken in. Then remove them. That's what I do.
