*sighs* oh God, I gotta do this very soon, not looking forward to it.

What's everyone's advice for the injector seals? It's like 40.00 for all 4, but do I need to do them? If so, do I need to get the tool to put them on?

I bought the seals and tool from ECS and wound up returning them after not noticing any fuel leaks for a day and half.

Check out my DIY pictures. Used a DIY walnut shell blaster pieced together from Harbor Freight and Home Depot. If anybody local needs to borrow an injector tool, walnut blaster tool, hit me up!

After doing my carbon cleaning, i put the injector seals on without the tool.

But after the cleaning i've developed a random misfire, its only happened 3 times now in the past 7 months. But still. Could be fuel injector related, i have no idea.

For the peace of mind i recommend you do it the right way.

I had 3 injectors that came out with the manifold. I tried to replace the seals without the tool and had at least 1 fuel leak if not 2. I am guessing I would've had better luck not trying to replace the seals.

So I had to do the whole process all over again the next weekend. If you are going to replace the seals, I recommend getting the tool. My brother will need the cleaning done on his CC coming up and I told him he can borrow the tool for $40, so I will make some of my money back.

Also, I did not use media, and didn't get nearly as clean as the images above. I did get large chunks out and the stems are very clean, but the backside of the valves still has probably a 1/16" or so thick layer of crusted stuff on it. Even with that, it was a noticeable, I think, improvement.
