I drive her daily and push her hard at times. Valve stem seals leak, so its always topped off with fresh oil. Cooling system is consistent and coolant/tranny/diff fluids are replaced every 2 years. Nothing looks like it on the road or in LA. Yet somehow the more miles she racks up, the more reliable she proves to be. What a life!

That speedo does not appear to be from a Series 1.2, or 3 XJ6/12.
It looks more like an XJ 40.
If it is an XJ40 or similar you will have an AJ6 engine and they have an incredible survivability.
I know of one in my local area that has passed 500,000 ks (about 300,000 miles) and is still going strong.

Perhaps you are in the wrong part of the forum?

Cheers

 

Ahh dang it! Can a mod move my thread over to the XJS forums? Sorry about that!
