Re: Turbo I waste gate check
first verify the wastegate actuator (WGA) rod is still attached to the wastegate ..
often the clip holding the rod on corrodes away, then the rod pops off
(more common on Mitsu turbos)
now you need a compressed air source and a 'blow gun' ..
trace the vac line back from the WGA to the electric solenoid on pass side shock tower;
disconnect there, and *gently* use your blow gun to apply compressed air to the line to the WGA.
the WGA should cycle with only 6-8 psi ..
(too much psi applied here could rupture the WGA diaphragm so be gentle)
verify that it is actually cycling the wastegate and that's not seized up.
