Injector Seals

[arbess]

Ok this is leading on from my old thread Click here to read.

What I would like to discuss is injector seals. There are three seals on a injector:

1: on the top [on the top tip in the fuel rail, o-ring];

2: another on the top tip, sits inbetween the injector and fuel rail, and;

3. on the bottom that sits around the bottom tip and engine block.

What I would like to find out, has anyone ever had anyone of these 3 fail on them, as in break or wear out? If so what did it do to you engine operation?

For me I have a worn out number 3 seal on one of the injectors and i believe the residue build up on the o-ring is a fuel-aix mixture. My car is suffering from what seems to be hesitation. From my old thread I have gone through the regular checks:

not fuel pump;

not ignitor pack;

not coil wire loom;

not coils;

not spark plugs;

not earthing cables;

not afm's;

not wheel rolling diameter.

If anyone would like to leave a comment to futher progress this issue, that would be great, it would help me and possibly others in the SAU community.

Thanks
