Turbo acting up.

[Chevysrule454]

98 chev 6.5l. noticed my turbo was kiking in and out on my last tow . Got so bad it stopped all together. Checked
ump
lastic vacume lines
:Wastegate cintroll valve
:Wadtegate itself.
All work fine. So im assuming its either a broken wire before control valve or my ecm is done. Can simeone tell me the advantage of a mechanical wastegate and how it would work with my stock setup. Also what ALL id have to do to install one?

First off your gonna need a boost gauge. Second you should do a google search for 6.5 mechanical waste gate or go over to diesel place .com. That site is dedicated to gm diesels

Did a little testing today and everything works properly when the engine is cold. Then slowly as it heats up the turbo works less and less then finally it stops altogether with no vacume goung to the wastegate actuator. Even after the actuator solenoid was replaced with a new one. Even more confused now. Still cant get on diesel site.
ANYONE?

Well if the solenoid has been replaced and all vacuum line are good, my only guess is that the vacuum is
Shot. A google search will show home made mechanical wastegate with a spring. Very easy to make

Tried it today when the engine was cold and everything worked as it should. The hotter the engine got the later and later the turbo would spin causin more and more black smoke/ no power until the engine was up to temp and the turbo stopped all together. When the motor was cold the orange plastic tube from the pump was reading 25" of vac at idle and 18" from the actuator at idle cold. When i got back home after the turbo not working at all there was 0" vac from the black tube at the actuater and again 25" from the orange /pump hot. ideas/ thoughts?

Just looked around a little over at Diesel Place, they have a "Contact" page where you can send them a message to reset your password. Here's the link.
