Intake manifold bolts 4.2

[captain150]

I know this is a common issue and I tried searching for past threads on this. While I had the alternator out for other reasons I checked the intake manifold bolts and they were quite loose. I tightened the ones I could reach and I think I got them all except the one at the very back near the firewall. Any tricks to getting access to this one? Go from above or below? I have various sockets, wobble extensions etc and should be able to reach the bolt, but I can't fit my hand in to get on the bolt nor can I even see the thing.

I figured someone here might have a trick to getting to it.

It's been a minute since I've done them. I think used a combination of either a shallow or deep socket, a short extension, a swivel and a ratchet.

Don't forget the one behind the PCV hose that connects the intake to the block.

Happy Canada Day!
