DIY: diesel injector pop test?

[golfcuntry]

Anyone have experience doing this? I need to service the injectors in my 85 jetta 1.6td, does anyone have a pop testing tool? Or know where I can Have it done for cheap? Trying to save a few $$ on putting refurbed injectors in the car by just buying the nozzles and some shims. Car has 212k on the clock, rings, bearings, all gaskets have been done recently, pump and injectors I don't think have ever been serviced.

I'd just pull them and send them in for work. I had my injectors from my Bus refurbished by Russ @ http://www.cruzinperformance.com/

He has the proper tools etc, and for about $100 and I had them sent and back within the week.
