1966 404 Coupé Injection Restoration

3 minute(s) of a 255 minute read

Today I got my 18 cleaned and tested injectors back from Nottingham Diesel Services Ltd.

The 6 NOS:
2 x DL0 20D - release at 37 bar, good jet, no drips
3 x DL0 20D - release at 35 bar, good jet, no drips
1 x DL0 20B - release at 33 bar, good jet, no drips

The 4 originals from my car's engine:
1 x DL0 20B - release at 29 bar, good jet, no drips
3 x DL0 20B - release at 27 bar, good jet, no drips

Random spare injectors:
3 x DL0 20B - release at 30-32 bar, good jet, small drip but OK
3 x DL0 20B - release at 22-25 bar, jet OK, but drips under residual pressure that could make cold and warm starting a problem.
2 - DL0 20B - defective

I'm going to use 4 x NOS injectors.

As you may recall, before Christmas I put the rear window in but there were a couple of issues: the lower stainless steel trim piece was perfectly straight and the class is slightly curved, so it was constantly trying to pop the clips out.  And so it did, once the glass was in.

After pulling the trim off I realized that the problem was also that the replica clips were about 2mm shorter than the originals and so didn't penetrate far enough inside the seal's rubber slot to engage with the small channel at the end where the hooked bit goes.  So each of the 30 clips had to be adjusted carefully by hand to match the depth of the 16 remaining originals, which were cadmium plated a couple of years ago.  In doing this - they're made of spring steel - 5 of the 30 snapped but 25 survived. 

I then mounted them to the SS trim along with the 16 originals and so far it's holding well enough.  Actually the rubber seal relies upon the window aperture to keep it tight.  So during installation I'm going to have to ensure the helpers push hard on each clip as I pull the rubber seal through to the inside of the car to make sure the seal clamps the clip in the right position (fully inserted).

Today, with the able help of my two daughters I remounted the rear window of the 404 Coupé with no problem at all, and the modified clips are working perfectly.

Took 5 minutes to install and this time I started from the bottom of the seal and finished at the top.  I used a smaller gauge nylon cord to do the lip service (!) this time and it worked beautifully.

YES!!
