I have a 2000 discovery 2 and have a flashing check engine light. From what I've found it's the plug wires. I have already purchased them but once I looked up how to change them it said I have to remove the intake and it's an 8 hr job. Has anyone found an easier way to do this? I was thinking about unbolting the body and lifting it up some to see if it would give me the clearance I need but wanted to ask first to see if anyone has tried it.

 

People with small hands have successfully done the swap without pulling the intake. They take there time and do one wire at a time.

Never heard of anyone unbolting the body and lifting it to change them. Doesn't mean it won't work, if you go that route take pictures.

 

 

C4 is a time saver for getting the body off the frame...and a heck of a lot more interesting...lol.

If you don't have SAI, probably doable with patients and more patients...and you don't mind the sight of your own blood.

Me, l'd just remove the upper intake and enjoy the experience some. Plus, you can look over the injector wiring harness while in there.

Might be a dumb question but will I need to replace the intake gasket? I'm thinking I will but it will take a couple days to get it and I'm hoping I can change these wires tomorrow.

 

Do you have to no, should you yes. Would I? Yes, if I don't it will leak and run like a bag of hammered butt holes

 

Ive done it both ways, mind you my truck has SAI. By far removing the intake is the way to go. Plus, you can check up on other stuff like Brian suggested. IM gasket is cheap.

 

I've done the job keeping the IM in place, and my truck has SAI. It's going to be a PITA. If (when) I were to do it over again, the manifold is coming off.

 

Truth be told, when you consider the age of these things (and quality of parts)...you'd probably be better off replacing the injectors while you're in there...or having yours checked/cleaned. Or, at least, replace the o-rings on them...since they've probably been through a million heat cycles during there lifetime.

I believe the majority of the running issues most folks see with these things are vacuum leaks at the injectors, or bad injectors. If you go the extra mile and replace them now...you will at least know they are good to go for another 100K.
