I am replacing alot of things so I might as well make sure the injectors are workin right(they both have over 138xxx miles). i am going to be using stock injectors. On both of my primaries the plastic cap on the bottom is cracked. I am also needing the rubber seals that seat in the primary injector ports in the block, as both of them are pretty trashed. Also on one of my secondaries, the port looked very dry compared to the rest of them, so I'm thinking it may be bad. Seeing as how it would probably be just as much to flow test and clean them as to buy or rebuild them, I was wondering which would be the best for my money. So, low mileage all new ones? Or send them all off to RC to be rebuilt? thanks.

With that many miles I would buy new if I were you. For the rubber grommets and also the plastic diffusers that sit under the grommets, get them from ray crowe at malloy mazda, 888 533 3400.

Is the engine apart or are you doing this with the motor together? those plastic diffusers have been known to fall apart and ruin engines, so if yours have that many miles on them you definitely want to replace them. It's not fun though, esp the primaries.

There is no such thing as rebuilding an injector. You either clean and test it or get a new one.

Cleaning and testing is MUCH cheaper than buying new ones. $70-$80 for all 4 including shipping. I sent mine here: www.cleaninjectors.com

A good injetor servicing company will give you a before and after report and let you know if the units are reliable or not electrically.

In your case I would purches new ones.

Why do you say that?

I spoke to someone at RC Engineering about this a year ago. I asked what the life of the injector valve assembly is. He said they should be replaced by 150,000 max if they are run at high duty cycle levels.
