2000 LS V8 Timing tension bad? VIDEO! Please view.

Joegr, I may be wrong, but answer me this - The tensioner I bought came with a Jag part # on it, but it was advertised as being for either the 4.0 Jag or 3.9 LS. How could the engines use the same tensioner if the valve trains were really all that different? And if you follow that link I posted above to the Jaguar service manual, you will see that the "special tools" are the exact same ones called for for the LS. The Jag cams have the flat area on them to time them, just like the LS. Seems like way too many similarities for the engines to be all that different.

Wikipedia speaks:

The Jaguar AJ-V8 is a compact DOHC V8 piston engine used in many Jaguar vehicles. It was the fourth new engine type in the history of the company. In 1997 it replaced both designs previously available on Jaguar cars: the straight-6 Jaguar AJ6 engine (or rather its AJ16 variant), and the Jaguar V12 engine. It remained the only engine type available on Jaguar until 1999 with the launch of the S-Type, when the Jaguar AJ-V6 engine was added to the list. The AJ-V8 is available in displacements ranging from 3.2 L to 5.0 L, and a supercharged version is also produced. Ford Motor Company used this small V8 in other products as well, including the Lincoln LS the 2002-2005 Ford Thunderbird as well as in several Land Rovers.
The AJ-V8 was designed to use Nikasil-coated cylinders rather than the more-common iron cylinder liners. However, like the BMW M60, high-sulphur fuel reacted with the Nikasil liners and caused engine failures. Jaguar replaced affected engines, and has used conventional cast-iron linings ever since.
The engine uses a two-state Variable Valve Timing system to switch the intake cam timing by 30°. Newer engines use a more sophisticated system which can vary intake timing incrementally up to 48°. The Lincoln version was made in the United States.

I stand by my statements. The LS engine is derived from the Jag engine, but it is not actually the jag engine. Your statement above is part of the proof of that. The LS does not have timing control of the intake cam/valves. It only has control of the exhaust valves. However, the LS's system is not a two state one, but is instead a continuously variable one.
Do some searching. Even on this forum, the fact that the LS engine is not exactly the Jag engine has been covered several times. This is all true for the gen II V8. I don't know how much the gen I V8s had in common, but I do know that there were differences between the Lincoln and Jag versions. AFAIK, the transmissions are the same. I think that at the time (when Jaguar was owned by Ford), Jaguar insisted on some clear differences between the Lincoln and the Jag to keep their brand up.
