Hi,
what nozzles come in the 1.6 NA hydro head, when I opened up my injectors, they had mercedes 240 nozzles in it, while I have come to know that the 1.6 hyd head motor is supposed to use SD265 nozzles.
any help on that - and as bosch are getting very rare now, what other replacements are good.
Hallo,
I would advise DNO SD 297 or 273.
These are pre-injection nozzles, buildt in early AAZ and 1y engines. They are phantastic so-called "whispering nozzles".

I came across this ancient looking guy with a small diesel shop who installed a set of ND denso nozzles in the golf's injectors he cross referenced to the bosch items. Did a half hour job on my pump . DAMN this thing runs like burnt cat now. :twisted:
Ive only got slight hazy smoke till 3/4 throttle and dark grey smoke at WOT
The guy said they are for some yanmar engine - but the 1.6 NA requirements are fulfilled by it.
Im also noticing less diesel rattle at idle but the speed seems to "hang" when decelerating, even when coming to a stop it will "release" to idle after a second. He says to forget it, because the nozzles flow more than stock.
With the smoke you have and the "hanging idle" it sounds like you could use a little turn (loosen) on the screw wit the 13mm lock nut, I had the same issue with a hanging idle lately. You probably only need an 1/8th turn, it is a very sensitive screw, this will reduce smoke at WOT and make the car a little slower though.
Turn this screw in 1/4 turn and see what happens
You need to loosen the 13mm lock nut
it helped the hanging idle but I lost power, I took the car to the pump repair technician - he readjusted the pump lever and power screw - it doesnt hang now - now it just releases its rpm from like 1000 to 850 (just guessing) after a second when I come to a stop.
The nozzle part number is 093400-3310
I think they are equivalent to the SD297 nozzles and they are extremely quiet - any nozzle gurus??
btw the nozzle make is denso
