Default Oil leak frustration

I've got what I thought was a leaky valve cover on my passenger side. Oil was dripping from the back of the timing cover near the intake cam. I can't see true source of the oil because it's obscured by the way the timing cover moulds around the intake cam area. Anyhow I purchased the OEM valve cover gasket, pulled the cover, used a copper brush and plastic scrapers to remove all the old sealant and put on the new cover using Permetex Black. Unfortunately the leak is still occurring in the same area. Any thoughts on what is happening?

Did you replace spark plug seals and the half moon seals? You only need to add sealant in specific areas....plenty of info here to see where. If you did those gaskets already you may have pinched one when re reinstalling them or the half moon wasn't seated correctly. Best bet is to clean everything really well and see where it is coming from. Passenger side can be valvecover, turbo oil feed\return leak, PCV is bad so it blows oil out under high RPM, etc. They also have UV leak detectors you can use with a UV light.

An oil leak from the back of the timing cover could also be a leaking cam seal. You can get the outside piece of the timing belt cover off with a bit of work and check if there is a drip trail coming from the bottom of the cams.
