Hi Guys, I'm interested in tips on removing the injector from the Fuel Rail (yes?/no?) , keeping in mind they have probably been in there for over 20 years, I tried removing one already and you can see the result in the picture ( Don't worry its from my spare car) so looking for advice like "cover with peanuts and chocolate sauce and it comes out a treat.." you know what I mean. Oh by the way, the Plenum is in the way...

This should help http://www.300zx.co.uk/forums/showthread.php?169704-Change-an-injector-dremel-method

Thanks Gary, seen that one, the main reason the injector in the pic is trashed was because i had limited, narrow access due to the plenum and it was a pig to release due to it being jammed in. What I was thinking was something like pouring v hot water over it to soften up the o ring's and ever so slightly increase the ally hole dia, all in all to make it easy to remove the injector. Would hot water there be an issue?

 

Cheers

Hot water wouldnt touch the O rings as they are sealing the injector in place lol, however, i remember Jeff did a write up a while back, using narrow mole grips around the housing of the top of the injector rather than the pintle in the centre. I wiggled mine a little, turn left then right a bit and it popped out.

Remember the injectors have been in there a bloody long time, so you need to crack the seal of the rubber to free it up, a light tap or wiggle, also try holding the part of the injector where the plug goes on, chance of less damage.

 

Having the engine warmed up will help

Are you sure is the injector and not the connector?

Hi, changed an injector back in December 2014.

Had to Dremmel out the plenum!

I completely destroyed the injector I removed!

U need as said a pair of narrow nosed mole grips to brake the seat of the screws first.

Then tackle the injector it will come out!

Never thought about making a thread about it !
