Gen 3 oil pressure

That was caused because of the TB replacement, did a KAM relearn and got fixed.

Do you got the same ticking sound when let off the gas?

No. I never did get the tick.

Four days ago, I changed my oil to 5W50 because I’m about to install an ESS supercharger, and shortly after that, I noticed the cam chain rattle along with the BBQ tick. I’ve read about the oil control solenoid and tried to unplug it. So, when it’s unplugged, there’s no rattle or BBQ tick, and the engine works a lot better. And when you plug it back in, you get a rattle and a BBQ tick. I still haven’t checked the cam chain tensioner.


I’ll be glad to hear any opinions about this.

Does anyone know the location where to unplug this solenoid? I would like to troubleshoot and see if this solves my ticking issue. As I have the same sound coming from my motor. It is about to be boosted and I would like to make sure everything is okay with the motor before proceeding.

I have suspected this for a long time. The "Tick" sounds like a lifter or lash adjuster, that is not pumping up fully, maybe one that is at the end of an oil galley. I assume this electronic pressure control is to squeeze as much "mpg's" as possible by reducing parasitic losses. No need to drive the oil pump that hard if under minimal load like at idle...exactly when you hear the tick.
