Hey judge or anyone who may know,



I sent my injectors to get cleaned and thought about replacing some stuff.



What is your opinion on replacing the air bleed diffusers and the rubber grommets that accompany them? I put new ones in when i replaced my engine 80k and 3 1/2 years ago.



I have new ones to go in but kinda don't want to get that involved with tearing it down that far.



Any help is appreciated.



Thanks...Scott

 

anytime you have the injectors out for service its a very good idea to replace the gromits as far as the defuzers unless there broken i wouldnt worry too much about them.

thats my 1/2 cent.

 

that was my thinking, but was curious on how brittle they may have become.

 

Well i just took out my rear secondary diffuser (air bleed), and for an engine with 80k and 3 1/2 yrs use the o rings were like new. The diffuser was not brittle at all. Still very strong.
