1992 E250 5.8 spark plug change
Hi guys,
I'm new here and need some advice. I took to changing the spark plugs and wires on my 5.8L Windsor V8 in my 1992 E250. Cylinders 3-8 were fairly straightforward. Cylinder 2 was a super tight squeeze but I still managed from inside with the dog house removed. I can't get to cylinder 1 (front most passenger side). I can just reach in to touch the wire but that's about it. There are 2 metal tubes running right beside it which make things even harder. Is there a trick to getting to this one? From below? From above? What's the preferred method? Please don't tell me I have to remove the alternator (spark plug is right below and behind it).
Thanks in advance for any tips!

I think I had to go thru the wheel well to get the front passenger spark plug on my 96. It was not much fun.
Working on the V8 in the van is one of the reasons I decided to swap a 300 inline 6 into my 89 E350 that has a perfectly good running 351W in it.

I could see the allure of a straight 6 in that regard! Fortunately for me I had most of the stuff removed from the front of my engine so it wasn't a big deal, but normally it looks like it would be a real pain. I'm not looking forward to changing them when the van is fully assembled, I can say that much.

Ok......I wouldn't tell you..........
But it makes it a lot easier to get to that #1 plug........
Other wise, couple of 6" extensions, feed under the heater box, behind the alternator, and EGR tubes and you got it.

Hey sorry I forgot to update the thread. I ended up moving the alternator out of the way to get to this last spark plug. I managed to do all of the others from inside the dog house, though that second last one toward the front was very tough as there's very little room.

I've done two tuneups this way (95 and 96 both with the 351) plus replacing the heads on my current 96's 351. It's a cake walk with the alternator out of the way. And with just 4 bolts there to move it, it's really easy. Far easier than swapping in a 300 six.
