I maybe wrong but I dont think anyone local can test pd injectors, used to be a place down south but their name escapes me now, monaghan direction iirc
google PD injector lash setting
I did but i still dont understand it lol.
Im not sure what it is or whether it is really necessary. So many different opinions.
Some are saying i need new seals, others are saying just stick them in and hope for the best!! Im just trying to keep costs down for things that arent necessary lol
If you fit a set of 2nd hand injectors, spend the money and get the new seal kits, buy them from Bosch or even on eBay but make sure they are using the Bosch part number.
Ideally you want them tested to ensure they are operating to their max potential (this also means setting the screws on the rocker arm) but it all comes down to how much you want to spend on them.
Well then at a minimum, new seals and bolts, fire them in and see how they go.
I do this for a living, so I always advise the best way to go about it.... unfortunately some people don't have a budget to do thing the right way.
I'll assume you're bolting on the 130 turbo etc? You'll easily run 160/170 for sensible money....go 200+ and you're into silly money for the gains.
