Typically they don't seize up often, but I've seen my share that were run through the beadblast cabinet and not cleaned thoroughly before being put into use. Then the beadblast material seizes the valve up.Thanks for the help I'll do it tonight. Is it common for the gate in the turbo to freeze?
Schematic no, but I have a couple pictures of various swingvalves as examples on how the actuator works in the swingvalve. These are different style swingvalves but how the puck actuates is the same.So I actually have two dodge 600 that I'm ultimately swapping engines on. I tested the waste gate on both. One I can move the actuator rod to move the waste gate shaft but applied 8psi to the actuator with no movement. I beleive I can hear the compressed air escaping like the diaphragm is leaking.
The other 600 I tried to move the rod by hand and air. Could get the mechanism to move at all. It appears the wastegate shadt is frozen. Is there an easy way to free it up? I've put on blaster on it hoping that will loosen it up.
Do you have a schematic of the turbo which show how the wastegate is configured within the turbo?
