Question about the VCT Oil Control Solenoid.
I have a leak coming from the VCT Oil Control Solenoid. Since there is no check engine light or other issues, it was recommended to try and replace the gasket for that area first, before replacing the whole part.
My questions:
Can I spray brake cleaner on that whole area, even on the harness/plug, to clean it up. If not what should I use instead?
Do I need to drain the engine oil (or a bit of the oil) I know oil will leak out, I just don't know how much.
From the instructions I've found so far, it's just 1 10mm bolt holding it in. After removing that I should just be able to twist it out. Is there anything else I should know. (I've only ever done oil changes and one time I my rear brakes)
Any other tips/advice is welcome!
Thank you
