It first showed up after a long trip few weeks back. Cleaned it up and kept an eye on it. Appeared to be that VCT module. Took it to mechanic who repalced 3 gaskets but it still leaks. He thinks through the bolts. But its going for a third attempt next week. Is there a trick to it!

The front cover yes. The bolts bottom out slightly so if not sealed up 110% right it won't seal and will still leak. We use to cut around 2-3 threads off each of the bolts holding the front cover on.
Have also seen them leaking out of the banjo washers and on the oil feed to the VCT - simple case of replacing the washers, and on the other side the bronze fitting putting thread tape around or other thread sealant.
The front covers can be a bitch to seal up. You have to get it 110% clean first, and use a decent sealant. Clear silicone generally isn't up to it. We usually use either Loctice Grey Maxx or (I think it is 3M) Black RTV Sealant, we have found them to work best, and leave for a good hour or so to set.

Also worth doing front Crank seal while the cover is off.

Oh, Ok cool.From what ive read they are a pain in the butt.He repalced the rocker cover gasket since it was off and two others. Ford ones. It was an hour job so not a biggy but when he told me I needed the Switch thing on the end of it (at $500) I didnt think that sounded right so I put tin foil around it for 3 days and it was as dry as a bone when I took it off but the the leak appeared to be still coming from the bolts. The top right one and maybe the bottom one. Hard to tell as oil runs down a. But I checked it after every short trip to catch the leak.On a longer trip it gets on th belts and sprays it on that switch so thats why he thought it may be that.Geez even I could figure out what was going on.

GUn, cleanit all up and spray it with 300 coats of 2K clear.That should seal it up nicely.LOL

Yup, we use to shorten the bolts slightly as the bottomed out inside the head/block and didn't pull tight.
