Title: Maually Activating VVT
Post by Ruds on Feb 9^th, 2018 at 6:38am

I am ready to do my first VVT test on a 2013 Cruze 1.4L Ecotech turbo. What I found by searching is this engine is a non-interference engine. I feel safe doing it on this. I have no codes. Tom on GT said watch for this. Question is I have, is it safe to do this on every engine that has VVT? Any one has any requests on captures. Let me know. I am going for compression, cam, crank, intake. Car is here now,should have car here for weekend. Ruds

The range the VVT will move will not cause an issue even with an interference engine. It was designed to move that far even on an interference engine.

If the timing belt Or chain is not installed properly or has jumped time then you could have a chance but it would of probably done damage already

That was what I was trying to say in GT. If you have any reason to suspect that the engine may be out of time, think twice about doing this test. Depending on how far out it is, adding the VVT movement could potentially kiss a valve.
