kkk wastegate stuck open
kkk wastegate stuck open
I can blow through the hose without any restiance leaving me to this conclusion.
Any ideas on how to get it unstuck?
I've backed the wastegate out 3 turns and the stud feels very loose also.
Haven't found a rebuild kit yet if it's going this direction.
Any help or suggestions are welcome Thank you.
Hi,after boat loads of reading I've found my k26 wastegate to be stuck open I believe.

so why am would my boost be so high during acceleration, up to 20lbs.
Maybe I've been misleading myself, I thought 8-12 lbs boost was the limits when correctly working.
I have spent hours reading here but that by no means gives me knowledge of what I'm doing/trying.
Background,
om617 from 84 wagon put into a Land Rover Defender 110.
All I've added, by recommendation was a manual boost controller.
I've also added a functional snorkel.
Future add on will be a IC and a better IJ pump when one becomes available.
Have adjusted valves too
It runs very well up through the RPM'S but the boost level has my attention.
At 63mph it's at 10-12 at say 68-70 it's around 18-20.
Can't figure out how to post pictures would if I could.
And Thank you for your replys/time with this.
I'd like to learn but need proper directions
Arrrrgggg newbie that I am....for sure.

There is a diaphragm inside which actuates the wastegate valve and should not let air through.
If the wastegate is broken in that way it is always completely closed and you´ve got as much intake pressure as possible.
As mentioned above the wastegate on a OM617A works with pressure, not vacuum.
The stock pressure is specified with 0,7 - 0,8bar = 10,2 - 11,6psi
With a stock pump everything above ~15psi is mostly just hot air you don´t need

If you can easily blow air THROUGH the wastegate it is broken if you ask me.
