I've been searching around and can not find a solid answer/guide. I found a thread started in March of 2020, but it received no responses despite getting over 600 views.

Does anyone know if the VVT solenoid can be changed without disassembling the engine?
I don't have a CEL light on or any DTC's.
I did, not long ago use BG 109 to remove any sludge buildup in the engine before my last oil change. I would like to remove the VVT solenoid to clean any "particulates" that might have attached to the screen(s) of the unit.
Any help is appreciated. Thanks.

What are the labels on those black things... As in the setup that he's asking about? I don't have my glasses on.
LOL, eh.

Oh, you mean the solenoid valves?

â—Ź Two solenoid valves There are two solenoid valves located in the control housing. They direct oil pressure to both fluted variators according to the signal from the engine control unit. Inlet camshaft timing adjustment valve -1- (N205) is responsible for the inlet camshaft, and exhaust camshaft timing adjustment valve -1- (N318) is responsible for the exhaust camshaft.

Perhaps reading the title of documents or the document itself isn't your strong suit. The whole damned SSP is called "Variable Valve Timing." Write much? Redundancy is generally frowned upon. You aren't going to refer to the solenoid valves as Variable Valve Timing solenoids every time.

But whatever, God @SaVAGeSoot . Or should I say Sheldon Cooper. You are right, I and every other mortal am wrong. We're not worthy!

Not having a VR6 to look at, how much room is at the back of the engine? Can you get to them without removing any covers? There is a cover over the end of the cams but I'm not sure how the solenoids come through it. I can't find a video on utoob showing how to get to them either in the vehicle or out. All of the videos seem to be out of the vehicle with the cover(s) removed.

@C-ya thanks for the positive direction.
After doing more searching it looks like the cam cover would have to come off. Not sure if it's a 1 or 2 piece unit but definitely not something that can be done without being a skinny contortionist with small hands, or without removing the engine on the worse end of the spectrum.
I do have one used solenoid unit that was tested as good and in looking at it I don't see any screens on it. It's possible I'm looking to PM something that isn't necessary.

On the screens, I'm not sure where they are located. They may be in the actual mechanism, not the solenoid valve itself. Some posts I found mentioned removing the screen and changing the oil more often.
