You have a bad VarioCam unit.

JFPinPA I could not upload the last two pics on was at 4000 rpm and 2600 and the numbers moved a about ten thousands of and inch they were still both -2.xx .Are you saying its bad because I found green rubber or the because of deviation numbers ? I am not questioning your skill .I have my old motor that has both vario cam units that I could steal .I know that there is a lot of green rubber in these Motors .All the Intake seals are green .The people who put my motor in had be buy two sets . if I pull a valve cover off will I see anything to tell me they are bad .I see the pic of the valve that is bad and the whole cycling assembly had to come all the way out .I am very confused as RND says there is no problems .Thank you for your help sir.

Are you saying that you are not seeing the actual cam angle change with RPM, or that the cam deviation values are not changing with RPM? You should see a massive change in the intake cam position with increasing RPM, but not necessarily any change in deviation.

I apologize for not knowing how to use the software .I think I see what I was doing wrong .I have to have the cam angle and deviation checked. This is what I got tonight.

At what RPM was that taken?

[gabedrummin]

About 4200 rpm.

Then your VarioCam is still working. You cannot just pull of the cam covers, that requires holding fixtures to prevent fracturing the camshafts.

At this juncture, I would suggest taking the car to a pro and have them drop the sump cover and see how much green rubber materials they find.

Thank you JFPinPA I will keep an eye on it now that I have learned what I should be doing .I have read that the deactivation should be within plus or minus 6 degrees .Is that correct ? And at what RPM ? Still not really sure what spec Im looking for as far as whats good and whats bad.Thank you so much to all the Forum members and especially JFPinPA Thank you sir.

Cam deviation is a measure of how far off the cam position is from the ideal position. The actual cam angle should move from near zero to around 24 degrees if the VarioCam goes active with increasing RPM. Cam deviation limits are +/- 6 degrees.

And please stop calling me "sir"........

Sorry Mr.JFPinPA its all part of Management training from my last job.Well brain washing .To treat everyone with respect . I was supposed to make my guys fell like I was there co-worker and not the boss. We made crankshafts for the oil industry started out as a 4000 pound billet of 4140.Now I'm back at Goodman as a tool and die maker. Been a die maker for 34 years now.Thanks buddy.

Hmmmm so the 3K rpm and above driving threshold has no vario cam wear benefits? (for 2000 3.2 S engines )
