Fuel Injector re-install question
I have a 2000 civic EX 1.6L sohc vtec. Just sent out my fuel injectors for ultrasonic cleaning and flow testing. Am wondering what the procedure will be for re-installing them back into the car. Any special tips or tricks to know? Never done this before so I have no idea and don't want to screw them up! Thanks in advance.

If you think a good mechanic is expensive, try hiring a bad one

Lube the rubber seals so they can slide in and not tear.

Okay I had ordered some grease for the o rings so I we be good on that. Thanks.
Some more questions. How do I clean the deposits out of where the fuel injectors go into. I noticed it's kinda dirty where they seat at (not in fuel rail but other part).
Also pulled a spark plug to check out its condition. Is this a normal looking plug? Looks okay to me but just want to make sure. I changed out the o2 sensors today cause the car has tons of miles on it and they were the original sensors. I figured what the hell since I'm getting the injectors cleaned. Thanks for all the info and help!

What's the brand and part number on the plug?
Ya, normal cheap plugs probably came in it.

I did post a picture. They are NGK plugs (iridium) I put them in back in March 2013. Was just checking on the condition so I posted a picture to make sure it was okay and no problems.
The old o2 sensors had white soot looking stuff on them. I have read that's normal and have read that indicates something. Now those were most likely the original ones and the car has had a leaking head gasket at one point but I got it fixed. It did overheat pretty badly too. So I am thinking the white soot might have to do with that...
Anyway. They are replaced now. I think the spark plugs are okay...again just wanted a second opinion.

For whatever reason, I wasn't able to see any picture on my computer at work. Sorry.
The plug looks fine IMO.
The old o2 sensors had white soot looking stuff on them. I have read that's normal and have read that indicates something. The white is just ash, it's normal too.
The sensor sticks into the exhaust, it can be 1000 degrees in there up close to the engine.
Antifreeze can contaminate O2 sensors and hinder performance/accuracy, along with contaminating the catalytic converter. Depends on if it was drinking antifreeze though, and how bad it was. Some live, some die.
