OK boys and girls looking for some input. This is my first time using a smoke machine. So bear with me, I am not looking to just change parts. Here we go.
1. Pulled the service port core and connected the smoke machine to it.
2. Ran it until I saw smoke leaking.
3. Found smoke coming from two spots in the left frame rail (a false source of leaks).
4. Pulled vapor canister down and plugged the vent tube. I assume it is supposed to be open?
5. Ran the test again smoke leaking from intake snorkel. Removed intake at Throttle Body and plugged the throttle body.
Leaks / Smoke found:
* Vacuum line: Dry rot (repaired with EGR Pressure Feedback Hose)
* Throttle body leaking from shaft seals/openings.
* Small leak at right front of Intake Manifold.
* EGR Valve
Throttle Body:
I assume there are not replacement seals for a simple repair.
Intake Manifold:
I assume the gaskets need replace, unless there's a crack or the bolts lost torque.
EGR Valve:
I assume it needs to be replace, I am guessing it is stuck and should not be leaking at all.
Any input is appreciated in advance.
Thanks.
