turbo failure or dash Guage????
« on: April 01, 2016, 10:37:31 AM »

Ok, ........OK
I decided last weekend to change my oil and filter after I poured sea foam in the crankcase to try eliminate some noisy lifters
While test driving it I noticed my psi Guage not working, also it seemed to be idling a little high.
So after I found a loose vacuum hose near the passenger fire wall, from changing my hard to reach oil filter, I thought it would fix my issue.
Nope!
I also temporarily disconnected another Vac hose from the brake booster and poured sea foam in it while the motor was running.
My question is would I notice allot of smoke if my turbo went out, and did I do more damage to it funneling seafoam through it.
Or should I continue hunting for a loose connection or Vac hose?

Continue hunting for a loose connection. The boost gauge is driven by a pressure sensor on the firewall that has a single electrical connector and a single vacuum line.
