RND engines thinks is CURIL T sealant ? Where do the o -rings go in the variocam units .Dose anyone have an exploded drawing that shows them ? If they come from variocam would it not cause the timing specs to be out of range ? Thank you you guys are the greatest ..!

Here's some great pictures from the link that I posted for you earlier (to save you the work of clicking and scrolling to look at it). It shows the green o-rings in a disassembled variocam in good detail.

Thank you 78f350 So it looks to me like the chain rail has to be completely gone for the hydraulic actuator to come out of its bore ? And release its internals. So I don't think I have this problem.I will check my cam deviation daily to make sure nothing is changing. Thank you all, this forum is an excellent tool.

That part is the only green rubber in the engine, and cam deviations at idle will not reveal it as it has no impact on those values. You need to look at the active cam angles after the VarioCam activates.

JFP, can you check them while driving on the freeway (with a friend) looking at the Durametric?
