fuel injector inserts

[millertyme]

The final results are in.....
The car starts immediately everytime for the past 2 days (3 cranks max).
I find myself holding the key too long now (a bad habbit I have to get
past).
Tomorrow I do the timing belt and both seals (cam and crank)
Hope it goes as well as the injectors.
Thanks again to all who had input.
Brian

Well,
The job is finished.  All but one lower seals came out with a hooked
piece of wire.  The other one, of course it was #5, came out in pieces.
I removed many pieces, then decided to use a 1/2" tap.  Threaded it in
by hand, until I felt the insert turn, and it came out with a gentle
tug.  Not much left to it, but at least it was out.  All new inserts,
seals, and 4 new injectors (one was replaced last fall). As it sits now,
the car fires up in the first crank after sitting for an hour.  The real
test will be tomorrow am and see if it still spits, sputters, and puffs
blue smoke when it first fires up (after 10 + seconds of cranking). I
will be keeping my fingers crossed, but I do believe that was the
trouble since after the injectors were sitting on the top of the engine
for about an hour while I removed and reinstalled the inserts, all of
the old injectors were wet with gas. I will post the results Thanks for
the input from everyone. Brian

Good idea for the tool... but how about using M8 hardware. I think M8
nuts and bolts require 13mm tools exactly. M8 stuff should be just as
easy to find in any hardware store, esp. in Canada. good luck.

Kurt,
I have all the new items coming in tomorrow am.  Hope to get them all
replaced after work.  How deep does the allen wrench go into the
injector holder? I don't have one that size so I will be using a 5/16
bolt (1/2" head) with a nut welded at the appropriate depth for turning
out the insert. And for the seals, I picked up a bottle of silicon based
o-ring lubricant.  Wont deteriate the rubber, and it goes in slick as
.... Best stuff ive found yet. Thanks again Brian

Replace all the o-rings and all the inserts. The insert should be the
red plastic ones. They clip onto the brass holders so they should come
out together. They are most likely to break putting the injector back
in. Total parts should be around $20 with bosch viton holder o-rings.
You should do this job with the engine warm if at all possible since it
makes a huge difference to the hardness of the large injector o-rings
(even new ones). Sears has a 1/2" allen that works good for taking out
the inserts. Clean the brass injector holders with emory paper while
they are out. Lubricate the injector holder o-rings with plenty of gas
before attempting to put them back in. Do not attempt in the cold or you
will waste the holder o-rings and inserts (BTDT).
