Dawes valve. Will I need one.

[Malfunction777]

Hello all
I’m just starting out with all these modifications thanks for all the info would love it if you added some photos of work then can put two and two together.
I’m about to rebuild a zd30 that I got a month ago with a hole in no 4 piston had done 396000km so not a bad effort.
I have been trying to download manual for it but need to do more chatting then hopefully I can get one before I start rebuild.
Was wondering if there is a stronger aftermarket pistons available and if so where to get them
Thanks Mal from Alice Springs Also

@Malfunction777, best to start up your own thread and ask specific questions as you go. Help is here mate but we do not know how much you do understand. So many install options but depends on you proposed set up.

Wish I posted a mod build thread at the start, would be a good reference to trace progress of build mods and performance change over time.

Hey Mr Malfunction. I installed both a Dawes valve and Dawes needle valve. In the end I pulled them out and installed a diesel smart 20psi actuator in their place. Much simpler installation. But you can’t adjust anything once it’s installed. That doesn’t worry me yet. Hopefully it won’t. Cheers, Brian.
