Injector Nozzle Replacement; stuck injector bodies/shims

Hi All,

Used Kent's handy manual/kit for the Monark Injector Nozzle swap. Am in the
middle of the job... two of the injector nozzle bodies don't seem to want
to come out (the other 4 came out pretty easily). Ditto for several of the
shims... some blew-out with a little blast of air/solvent... the others
are sitting tight.

Any suggestions? I've tried "liquid wrench" on the nozzle bodies... so far
no luck.

I was surprised that one of the nozzles was way more rusty than the others;
also, if any of you are contemplating/preparing for this job, I'll save
you the puzzlement: sometimes the crush washers/heat shields come out with
the injector body... so you don't have to sit there scratching your head,
wondering why some are longer than others... Doh!

Cheers.

Bill M.

91 350SD smoke and miss

91 350 SD smoke and miss at start

--------------------------------------------------------------------------------

A recently purchased 91 350SD inline 6, 3.4 turbo with 162K.

Car smokes and misses at startup. The car was always warmed up when testing and checking prior to purchase... you know the story. I'm trying to solve the inherited issue with little luck. Otherwise aside from a couple small issues, it's a jewel.

Sometimes it smooths out and runs like silk with no smoke, other times symptoms persist. As it warms up and smokes it makes an occasional sound like a small dog sneezing as it misses, sorry thats the only sound I can relate it to.
