pulling fuel injector issues...

I'm replacing my injectors and ran into a few issues with 3 of them--this is a 91 g30 van, if that makes a difference: it seems as though the passenger side ones have the head bolts butted almost against the injectors. SO my 30mm socket won't fit down between the head bolt and 2 of the 4 injectors to get enough purchase to twist them. Has anyone actually had to pull some head bolts to get these out, or is there a thinner-walled socket out there?

I'm having some clearance issue on the farthest forward driver side injector with the firewall. I can fit the socket, but can quite fit my breaker bar or ratchet onto it in place--might try to find a 30 mm wrench to get that one..

Anyway, I just figured I'd ask if anyone has had any experiences like this in case there are some "dirty little secrets" that could help make my life a little easier.
Cheers!
Stephen

I used a 1 3/16" impact socket which almost the same. I had to grind down the mouth of it a little bit all the way around to make it clear enough, worked fine after that

My Snap-On S-6128 GM injector socket is thinner then any of my regular 30 mm or 1 3/16" sockets. If fits when they sometimes will not.

I did my injectors and holy mother of god, some front ones were a royal PITA. I bought the Snap On socket and took out all the injectors without removing head bolts. You will have to use a combination of thin ratchet's and wrench's as the above socket takes a wrench.

I've done this in a van. It is hard. The front passenger side you can get if you reach into the engine bay left side with your left hand below the alternator. The drivers side you can reach from the bottom front of the vehicle. OTC 5060 helps a lot.

I read that you should take out the alt, makes it easier but I didn't, too stubborn.

Thanks everyone! new question

got the back (front of the van) drivers' one with a big 30mm wrench. I'll grind down the socket I have to make it work. Now I have another quick question on Injectors:

The Bosch ones that are currently in there aren't the same # as the ones recommended by Rock Auto & a few of the other sites out there. The current ones are Bosch 0430211058. I found a killer deal on some new Bosch ones that list as compatible (Bosch 0432217092 (NA51X)), but it's only 5 injectors available. Will these work with a 91 6.2 van? Is there a problem using 5 of these and 3 new ones that are the same model as the ones in there now?

THANKS!!!
Stephen

I wouldn't mix and match unless you have them checked.
