I was told that my jags engine 3.6 may be replaced with 4.0.

Hi
If your car is an '87 it will be a 3.6.

In reply to a message from Robertas24 sent Sun 13 Feb 2005:

Here’s a reprint from the archives of a post I made about 10 days
ago:-

‘‘Look at the engine serial number stamped on a web on the block on
the right side near the front behind where the distributor fits. If
the second character is a ‘D’ it is a 3.6, if an ‘E’ it is a 4.0 -
or it may be a ‘B’ in which case it is a 3.2.’’

But as Phil says, unless someone has swapped engines in the past,
an '87 XJ40 will have a 3.6 (or if SOHC, a 2.9)–
