Re: rockergear/cam tick?
Yer, im afraid it wont go away. When Lifters tick for a while before the oil pressure builds up, this means that oil has drained out of the lifter over a period of time. When they never build up oil pressure it means that they leak to much to build up the oil pressure and push the valve down = rough and vibrating motor. It could just be one lifter, it is just hard to spot. Start it with the rocker cover off at idle and try to track down which one/s it is. Have rags where you dont want oil to go. Then replace it. They are pretty expensive pieces. That, or your camshaft sprocket, chain, chain guides could be about to shit itself and this would be very very nasty. Take the rocker cover off:)
