I have searched this problem up and down. Basically, some say you don't have to remove the AC accumulator behind the PCM. They say it is tight, but can be done. Well, 2 hours later I have made no progress removing that cover. I have pushed all wiring harnesses out of the way as best as I can, but the one thing keeping me from lifting the cover off is accumulator outlet line. Is it possible that some engine bays are slightly varied and won't allow this based on that line being 2 degrees further over? What are my options? How bad is it to drain/bleed AC and remove that line? Obviously half the components are already off and I would have to tow the truck to a shop. I would like to avoid this as this is already a pain in the butt job and my time is running out. Hopefully I have not already scratched something under the valve cover trying to get it off. Somebody give me some good news.

 

Unbolt the accumulator, gives you a tad more room, also make sure to remove your VCT solenoid otherwise you will snap off e connector, stuff the whole with rags an just keep working. It'll come out.
