Title: TD Pop Pressure Variants?
Post by: ObscuredByClouds on December 14, 2008, 11:43:03 am
I took apart my nozzles to put new smog ones in, and there was 130bar stamped in it. N/A nozzles? I have another TD engine and that had 130bar as well, makes me think there are some factory equipped 130bar TD's.

What do you think?

That's just what the housing says. Gotta pop test'em.
I wonder, can ya run the motor on three cyl and take the remaining injector line to look at the injector spray pattern?

you can turn the lines all upside down, crank it over and look at the spray on all four.

OR if you have the belt off anyways - turn the pump with a ratchet. (make sure you don't turn it the wrong way (ie. to undo the bolt/nut)
An impact gun would work well.

ya do the upside down method and have someone crank for you, but just stay a good distance away from the injector.

That's not going to tell you the opening pressure though

I tried that when I did my compression test the other day, doesn't work. The upper rad hose is directly in the way of #2 injector. Actually the injector line hits the underside of the rad hose so you'd have to loosen rad mounts, kink the hose sharply to the side and when you stop holding the rad hose it would pop back and wipe out the injector line :roll: I guess if you had a different hose configuration it might work. :)

If you guys had your engines turned the right way, you wouldn't have these problems. ;)

No such interference in a longitudinal Fox application.
