Tick Tick Tick from engine/ Coolant in Oil
Just picked up a 1999 XJ with 115,000 miles on. This morning I noticed a tick, tick, tick coming from the valve cover area (definately not bottom end). It seems to come and go at all at idle and througout acceleration. Speed of tick increases with engine RPM. It's not a leaking manifold. I picked up a can of rislone to run through it. I'm wondering if it's safe to give it a couple hundred miles to work it's way through or if I should take it in to be looked at right away. I don't know any of the history of this engine.
EDIT- coolant in oil, see below...
