Variable valve timimg actuator issues

[Porsche Enthusiast]

I will let you know what I find when my durameter shows up. We changed out the tensioner to no luck. It runs better that it did before, but still CEL flashing and the codes below off my POS Elm unit. Total waste of time and money on our end both parts wise and diagnostic tool wise.

Getting to the 2nd bank tensioner was difficult, but relatively simple compared to replacing the actuator, which apparently need a motor drop. I miss my VW bus, I could drop the engine in 20 minutes flat...


Chris, I was steered towards Durametric by JFP in PA below, which will apparantly give you more abilty to test out the actual var timing solenoid that actuates the tensioner. The reader for a laptop and software was around $300 with shipping. From what I have seen spend the money on a good diagnostic tool.

We are betting the actuator is dead, but why pull an engine if you aren't sure.

[JFP in PA]

Your tensioners are "passive" (activated by oil pressure), while the VarioCam system solenoids can be activated by the Durametric system, allowing you to see the cams actually advance and retard in real time, as well as measure their deviation values. When you get your system, look at the "drive modes" which will list all of the function available for you to activate and test.

JFP you rock for the guidance. May I call on in future if needed? I will do through the forum of course. Thanks.

Can I ask what happened here? This is the noise my car makes. I had assumed tensioners, but you say you replaced yours to no effect?
