Sourcing injector nozzles for 1.6 NA diesel
« on: January 12, 2025, 05:22:42 am »
I have a small stash of old injectors. I found four of them which have good looking nozzles. They have to be at least ten years old. All I can find for new nozzles are from India and I don't trust them one bit. Metallurgy and precision are key here. Yea they have a Bosch stamp on them but Bosch isn't Bosch as I knew it.

Anyhow I thought I was being slick using old components and as I'm going through those four injectors, three of the nozzles are already marked India. Then there's one with just a number and no name or country of origin at all. Again, these injectors are at least 10 years old. The no name one had a tiny blemish on the needle and was jammed pretty hard. It was also somehow stained with carbon where at least the Bosch of India ones would clean up.

Is this it? If we want the good stuff is it raiding junkyards or get real lucky and cleaning out old parts hoards? I'm sorry but I do not trust India to be making HSS precision components especially if it fractures my engine is going to ingest it.

We went Mexico, then China, Now India. We went orders of magnitude cheaper on production but prices are going up. If I'm forced to buy crap, why isn't it pennies on the dollar?

I just want to keep my stuff running. Where do I find REAL stuff?

The india stuff is not bad. Every once in a while youll get a bad nozzle right out of the box but generally they will hold up. Not like the original german/french stuff or brazilian but they will work fine. IDI is overall quite forgiving; if the nozzle isnt worn to the point where it leaks, pisses or has a bad (wide,uneven) pattern it should.work fine.

I may have one spare set of mixed 273/293 nozzles but if you ever need 308 (aaz) i have a few sets set aside.

Junkyards are actually a pretty good source. Typically bad nozzles are not the reason these cars get parked and since NA and turbo nozzles are identical you can usually find some good ones. Shops arent best source since they will replace worn units but more times than not they will have good cores or NOS stuff sitting around. 1.6 is fading, the stuff usually comes cheap.

There's a junkyard about half an hour from me. Original owner had hundreds or air cooled examples and probably 20 TD and NA diesels. Someone came in and bought the place, liquidated what he could and crushed the rest. He wouldn't sell parts. Wanted to make room for more modern stuff. Everything there was sitting for at least 20 years and rotted to heck but a *** ton of good parts. The guy wouldn't even let me go in to Death Row and whip stuff off quick as possible without holding up the crusher and pay scrap on what I could get before it got crushed. I get it, he wants to run a business and no nonsense but so many good parts got scrapped.

I've seen batches of core injectors on E-bay going pretty cheap. Not sure what I ought to pay for cores but may be worth it just for shims and possibly nozzles.

If you and plenty of other people have been running these India nozzles I guess I'll give it a shot. I'm not so scared of them malfunctioning but more of if something is wrong with the metallurgy or heat treating or something, they shatter and my engine ingests pieces of HSS.

1.6 is pretty much a throwaway item to a lot of people. They can't wait to get it out of the way so they can start on a VR6 swap, hack a bunch of wiring up, realize it's more than they can handle and try to sell a basket case. Of course they don't want anything to do with that lowly 1.6 but after they get it out they seem to think it's made of gold.

I love them. "Performance" is not in it's vocabulary. It gets you there in it's own time. It sounds like a farm tractor. It'll keep up well enough on the interstate. Cheap to run, easy to repair and maintain and rugged little things. They're faithful. I wish I had a better understanding of the injection pump, they scare me, but I guess the common guy doesn't really do much with those anyhow unless you happen to have some real Uptown equipment for bench testing them.

I think a lot of them got parked/scrapped simply because they were old and fairly Spartan and they were getting long in the tooth. I still kick myself for some of the ones I sent to the junkyard when I was a stupid kid. If I had stupid amounts of money I'd buy up those 1.6 diesels that people are tearing out, transmissions, parts cars, dealer tools, whatever I could lay hands on.

If you want some cores, I have extras.
I'd sell them cheaper than ebay.
 With the india ones, if you want 4, you should buy more than 4 because one will drip near the breaking point, or spray to the side.
I don't think they will explode and enter your engine, they are still made of very strong steel.

Right now I have four that ought to work alright. Spray patterns are not ideal but leakdown, break, and chatter are all good.

I saw a batch of 44 cores on E-bay for $374. I don't know about all that. I want all the old NA diesel stuff I can get my hands on but I don't have that kind of money. That'd be $8.50 a piece which seems alright. If I had it I'd go for it. Likely to be good parts in that lot.

I'd sell a few for $5 a piece.
 Won't be any good ones though, just cores.
