Default Stripped out threads for the banjo bolt on the cam cap for AVCS. How ****ed am I?

So last night I was finishing up my motor. Tightened the cam cap banjo bolt for the AVCS just a tad too much and Bam. Stripped the threads out.

What are my options? Right now I'm leaning toward drilling it out and having a machine shop install helicoil or something similiar.

Or

Making my own AN line and drilling and re tapping the cam cap/AVCS solenoid banjo with an AN fitting so I can run it.

Replacing the cap is pretty much not an option as I am not disassembling everything for a line hone etc

Either drill it out and heli-coil yourself, or let someone else do it.

Don't do only part of it because if something goes wrong, the shop will blame you since you brought it to them already pre-drilled

i'd be a lil worried about drilling it unless you can get the chips sucked out in the process, that and you drill away at the surface the copper washer seals against.

Is there room to tap it deeper and get a longer banjo bolt? Ive done that with an idler pulley before

Sorry wasn't clear. I'm not touching it if I have someone else do it.


Tapping deeper MIGHT be possible but doubt it.

I'm going to take the cam cap off, should be able to get everything out just fine if I tap/helicoil.

I'm going to give my machine shop a call and see what they say.

Helicoil is not a good fix, use timesert.

Take the cap off for the work, don't risk further damage. A good time sert or helicoil will be more than strong enough to hold the proper torque when re installing the banjo bolt.

Engine is out of the car so that's no problem. Thanks guys I will be giving a machine shop a call tomorrow and see if they can handle it for me.

Now to figure out this cam issue I just noticed last minute.
