New injectors or reconditioning?

[In-transit]

I have slim type injectors. Bit smokey under load, is it worth sending them to be reconditioned or cheaper to buy cheap new from eBay at £35 each?
Opinions?
Many thanks Arran

I didn't think you could recondition them, but it wouldn't be the first time I'm talking bollox, and where on Ebay have you seen them for £35? are they made from chinesium?
You could contact Stanadyne and ask for the details of your local supplier, they were about £70 each new and £10 P+P 18 months ago.

I was told by Ford at the time that you couldn’t recon them but a local diesel shop in Retford striped them down and put new nozzles in them I removed them outside his shop and watched him redo them must have done something right as it transformed the van.

How did he put a new nozzle on a stanadyne injector? They are an integral part of the injector body (i.e. not a seperate part)

Older injectors can have their opening pressure increased to normal, but many gallons of fuel flowing through the nozzles have increased their size.
If there is no money, but there is an opportunity to adjust the pressure for a small price-why not?
I adjusted the opening pressure of the injectors without a pressure gauge.
You can drive, but I bought new injectors.

He stripped them down in front of me and change some parts in them so it can be done I watch him do it so definitely possible Matt

"some parts" - so probably not the nozzle then?

The needle and springs etc are all removable, but they don't really wear. In reality it was probably a strip down, clean, reassemble and re-calibrate?

I think he-recondition them himself on old style injectors they used to lap the needles in with a very fine compound I think he did the same with the Stanadyne ones of mine . back in the early 90s when the first transit at work needed a new set we tryed Ford cf Parkinson and John Longdons in Lincoln who used to recon all our pumps and injectors all said no new only so a new set was fitted.
But in 97 my mk3 190 was a bit smoky and down on power and when the local travellers came down the street trying to beg scrap and asking if I wanted to sell my van I said no thanks I said it’s a good van only thing wrong with it was I may have to put a new set of injectors in it as you can’t recon them they said this guy at Retford can we use him all the time so I gave him a try as I said I removed them he put them on his test rig and the spray pattern was off and not atomising correctly and when held under pressure they where weeping from the tip after reassembling them and back on the rig they had no weeping and perfect spray pattern .you have only have to watch tv programs like wheeler dealers who re con components that manufacturers say new only .

[MinorMatt]

Oh yes, I am aware there are plenty of places that sort out things which are "new only"... but in the case of these the body really is....

Sounds like you got a clean up, reassemble and recalibrate. If the nozzle has had it then its throw away, it sounds like that wasn't what was wrong with yours

Maybe but but if I’d taken notice that it was impossible to do anything with them I’d have shelled out for new when it wasn’t needed I did another 30000 miles in the van and when I scraped it the engine went Ito a recovery truck and did a lot more miles.

Nozzles are part of the lnjector body OP go to a diesel shop for Standyne injectors, ebay is a minefield and you may well end up with more smoke than you started with. Have you done a service including the tappets on it and cleaned the inlet manifold
