I want to remove the intake and paint it. Does the injectors have to come off or can I paint it with them masked off. I got new vacuum lines and did not order injectors seals.

Taking the injectors off is not a very involved process. It would take you 15-minutes at most to remove them with the rail. You could leave them on, but you risk doing damage to them while carring around the intake.

You can get injector seals at any parts store. do yourself a favor and replace them if you take them out.

I just did this job - several things to consider while you have the intake off.

Vacuum lines - might as well replace them, I bought a silicon hose/metal fittings kit from Lindsey.

Throttle body - might as well reseal it too, I bought a kit from Paragon.

I also cleaned the injector tips with a ultrasonic cleaner and then put new seals on that I bought from Rennbay.

I got the arnnworx TB rebuild kit... good deal there. As far as injector seals and whatnot, Rennbay's kit is great!

dnwong, I have a set of unused injector seals if you want/need them. I'm local to you.

It's *pretty* easy to remove them, you need to bleed the pressure from the front by undoing the 17mm cap. Then you need to remove the clips. If they have been on there a while, you need to pull firmly. The rubber fuses to the intake manifold and makes it hard to remove. I can't imagine how you'd paint your manifold (so it looks nice) with it still attached to the car. Need to properly clean, paint the underside, etc.

Might I recommend that when you remove the injectors sending them to WitchHunter for cleaning/rebuild. That is assuming you can stand a few weeks downtime. Well worth the money IMHO. If interested do a search on WitchHunter (note: no affiliation)

I actually wanted to do the whole job in a day. The real projects is replacing the vacuum lines. Any local places in Northern VA that handles this.

Sharky, what type of ultrasonic cleaner did you use (Like a jewerly untrasonic unit?) What type of cleaning solution?

You can use Curries in Chantilly....for $100 hour. It is very easy to do yourself in an afternoon.

Where can I find instructions on rebuilding the injectors?

I pulled all four at once by pulling the rail with the clips still in place. I was able to use a prybar under the rail (very careful if you try this not to bend the rail). Then WitchHuntered. Lubed the seals with a little atf when reinstalling.

Poke around for grounds or other electrical connections that might be easier to clean with the IM off.

Oh yeah, bleed off the fuel pressure by cranking the car with the fuel pump fuse removed, then pull the rail cap (don't drop the ball bearing). Add have a fire extinguisher handy.

Rebuilding them is pretty easy. You just pry off the plastic end cap and pull off the rubber o-rings. Then put new o-rings on and press the new end cap back on. That's pretty much it.

If you can't find an ultrasonic cleaner, you can back flush them with carb cleaner and compressed air, or just carb cleaner. I attached a hose to the end of the injector, filled it with carb cleaner, presureized it with an air tank, then pulsed on and off the injector until all the carb cleaner had gone through it. After doing that once or twice I flushed them out the other way then rebuilt them. It worked quite well.

Be sure to pulse them on and off as they can over heat and you can burn them out if you just leave them in the open position.

They can clean the injectors at IMA in Merrifield. Cost me about $120. They came out great.
You have a PM back.
