Plenum pulled
Got a code 61. Found a drive side solenoid was not holding vacuum.
All replaced and done. I think the Super Ram is harder to get off then this ZR-1 Plenum. Are there any MLS gaskets for the plenum?

Re: Plenum pulled
Great to hear when someone does a fix. It means another ZR-1 back on the road. You might want to straighten the angle of actuator such that the plunger arm is straight. Helps with wear and tear

1. Leave Vacuum Canisters as they were installed at factory so you do not but different sort of stress on the bellows after so long a time. 2. Factory installed wrong....lets correct it now. Actually, there is a third school of thought (my own). 3. Install new Vacuum Canisters the correct way. Jerry's Gaskets has ALL the gaskets you need and you will have the gasket in two days (maybe three). I would give everything the Once Over since you are under there including cleaning out the Valley Drain tube and a complete inspection of the Secondary Vacuum System. I would also clean out all the oil and trash. I would remove the starter (not a big job) and pressure wash that area after spraying with Engine Degreaser. Cliff

Re: Plenum pulled
SOLENOID wouldn't hold vacuum?
I thought a solenoid was just a switch? Or is there a valve that's integral with the switch? |

Re: Plenum pulled
Yea actuator... Installed the same way it came out. Also looks like the same way on the other side....
I don't have a problem pulling the plenum off now...
