OIL ISSUE MY SON IS BUYING A 1994 JAG XJ6. CAN ANYONE TELL ME THE TYPE OF OIL AND CAPACITY? THAN YOU. My 1994 XJ6 4.0 releases white/gray smoke from the exhaust pipe when starting the car in the morning, but only for a few seconds. depending on the length of time the car is parked(drive to work - drive home)its possible the car will smoke again. Owner changed the valve seals and problem started again 3 months later. Any clues on how to fix this problem?

The problem is worn valve stem guides. You can replace the seals but as you learned will last about 3 months before doing it again. The only way to fix it permanantly is to **** out (resize) the valve guides, which means rebuilding the heads.
What happens is as the engine sits at rest, the residual oil film runs down the valve stem into the cylinders (or manifold on closed valves). When you start up this little oil is burned off, resulting in the smoking.
This problem will get progressivly worse because when something is worn, with continued use, wears faster. Estimate a year +, depending on usage, till you are smoking continuously due to so much guide wear that oil is finding its way in faster. changing the seals will last shorter time also as time progresses.

The jag 6 cylinder does emit white smoke on start up generally, its condensation being burnt. However, if it is excessive, you should check to see if you are losing coolant. Then its a whole new ball, game. Black smoke indicates excess fuel being burnt or lack of it , ishould say and blue smoke indicates oil burning.
Hope this helps

I have a 94 4.0L and I use 10W-40 in the winter and 20W-50 in the summer. It keeps the pressure up and it doesn't smoke when I start it because of the valve seals. It takes 8 quarts everytime including the filter. 2 gallon jugs. I change it about every 4,000 miles.
