Wow, I guess having long arms pays off on Aero's. I change my plugs from the front of the vehicle. I only remove the nut holding the oil filler tube brace and swing it to the side to get easy clearance for the passenger side plugs. The drivers side rear does take a little more time, but I just reach back there and git er done. If I remember, I put the socket on the plug then used a rachet with about a 4 inch handle (little short rachet). I did learn to wear long sleeves to avoid scratches from the throttle cable assembly. But, I changed all six in my 94 3.0 in about 30 minutes. I went thru the doghouse for the wires and cap, etc. I simply could not reach the drivers' rear plug thru the doghouse. (arms too long, I guess...lol)

You were actually able to change 2 passenger side plugs from the front? Mine looks like a total mess of stuff on that side of the engine ! I figured the Alternator at least would have to come off which means the serp belt & at that point I'm already going through the wheel well. Maybe I'll have another look at it! The rear plug through the doghouse is a challenge though. Next time (if there is one) I'm looking from underneath.

Yeah I removed the throttle assembly cover to get at the rear driver I didn't wear long sleeves and the tip on the end of the throttle cable assembly poked my arm repeatedly.
It looked like I had tracks up and down my left arm afterward
.
I'm not too large so I just jacked the vehicle up to get a bit of extra clearance in the wheelwell and replaced the 2 passenger with the tire in place.
Plus the vehicle was already on stands and the only other way to get the tire off at that point was to either lower the vehicle partially to hold the tire or bug someone to hold the brake.

Wheel well in place huh? I had a cousin that died when he did exactly the same thing you just described. He then scurried between the top of the wheel and the bottom of the wheel well opening. Guess what happened? Let's just say that the only thing he was doing next was traveling through a bright light and taking a number to pass through St. Petters Gates.
It is never a bother on your part or asking someone else's assistance in helping. The life you might save might be your own. take your time and please be safe.----------Respectfully Boz

The Vulcan lives on.
So the Misfire is now gone (so far so good). 
I fixed up the EGR tube because I cant find a replacement & used item is likely to be in similar shape to my old one (weak at the flare joint). Machined up a copper flanged pipe & pressed it inside the original pipe. Inside diameter hole is a bit smaller, but had to do that to gain enough wall thickness in the copper pipe which fits inside the original EGR tube. From the outside you'd never tell the difference. Van fired up perfectly, although when it warmed up (on the gauge) I noticed a bit of stumbling for a few miles . This has now gone, perhaps an adjustment to the fuel trims or similar learning strategy. Could have been burn off of the antisieze also? Doesn't matter....... she is now "firing on all 6".
Would not recommend Bosch platinums on the 3.0L Vulcan engine if your after maximum plug life, since when the centre electrode wears it becomes reccessed inside the center pocelain insulator & I believe spark efficiency is reduced.. The Motorcraft plugs have a much increased protrusion of center electrode, which seems to help when the electrode wears under normal operation.
When I have a little more time I'll put some shots up of the Bosch plugs & you can see what I mean about the center electrode wear problem.

That doesn't seem right that the center electrode should wear so much, as it is the platinum part. The other platinum plugs (Autolite) that I've removed usually show minimal wear on the platinum part compared to the steel part. Maybe it wears faster because Bosch made the tip too sharp in an attempt to make it more spark-attractive.
Having said that, I should also say that I had some bad experience with the Bosch platinum plugs in my 87 Mustang, which uses the factory E-coil and a distributor. It seemed that the engine ran rougher, and definitely stumbled (back-fired) more. Back to Motorcraft copper core plugs, and everything is fine.
