Removing Intake Runner

[It's SHO Time]

Well, I think it's time to replace my Plugs, and plug wires, and I was looking at how big of a pain in the butt it will be to change this stuff with the intake on. Is that correct, and if not how do you do it, if so is there a gasket that I will need to replace. Another question i'm going with motorcraft wires, good choice? What plugs would some of you guys recommend? Thanks for all the help guys, I don't know what I would do with out this place.
Thanks,
Justin

the [SEARCH] feature of the forum is an excellent tool. The questions you ask have been discussed many, many times.


Hey :MODS:~

So what's the latest on the FAQ page for the forum??

Removing the intake will take about an hour, that is if you can get the back support brackets loose on the bottom. Then another hour to get it hooked back up, at least. Once you do it a couple times it gets easier. Last time I did it my SHO was down for a couple days because when I put it back on, it did not run right and it took me forever to figure out it was a vaccume leak (after I took it back off to see if there was anything lodged in one of the runners )
Anyway, you would probably be better off taking the intake off, but you could change the plugs and wires without it off. You would have to slip off the end clips to snake them through the intake, but it is doable.
Yes, motorcraft is the best to use. Also, use the OEM platnum motorcraft plugs.
If you do take the intake off, go down to wal-mart and pick up about 8 cans of B12 CHEMTOOL and clean all of the gunk out of there.
Hope this helps!

You can remove the spark plugs without removing the intake manifold. You will need a spark plug socket and about 9" of extensions. The front three plugs are simple. The back three plugs require the removal of the vacuum hose at the passenger side and the secondary vacuum accumulator assembly. This assembly is attached to teh intake with a single 12mm bolt. Jjust remove the bolt and possibly the electrical connector and move the assembly out of the way.

A complication can arise if you find oil or dirt in the plug wells. DO NOT remove the spark plugs until all of the oil and debris has been removed from the wells. If not, you risk getting this junk in the cylinder which will certainly score the cylinder walls and shorten your engine's lifetime. Use the search feature to find out the different methods to remove this material from the plug wells.

If you find oil in the wells, that means that the spark plug well seals are leaking. these seals are part of the valve cover seal set that can only be replaced after the intake and valve covers have been removed. This seal set is cheapest from AutoZone.com as the Fel-Pro VS50378R for $71.99. But that's another story.
