Wow. Thanks for all the quick replies. I have heard good things about this forum from the "run you car on vegoil" crowd over at infopop forums, and you guys have not disappointed!

Tom J - what do you mean by lapping? Also since I have your attention - I've come across quite a bit of info from you and others on injectors on this forum - what is the best solution (currently just using a water/simple green solution) to use for cleaning the injectors ultrasonically? and what do you do with the injectors to make sure ALL the water is gone from the tiny holes? I fear putting them on the pop tester and damaging the pintle holes because of some stubborn micro droplets of water.

In the past I have used carb dip (not in the ultrasonic) to clean them, but I swear, that stuff is responsible for the injector leak in my Peugeot 505TD and I'd rather avoid it if possible.

btw, some day I hope to get a mercedes or three, and have been keeping my eyes open for a 190D turbo 5spd.

thansk again for your help.
