Rebuilding 2001 VandenPlas engine heads
#1

I replaced my timing chain and tensioners on a 2002 jaguar xj sport about a year ago and now its time for a new project.
I have the engine heads off and they are in the shop being rebuilt. The pistons look great and the engine is definitely salvageable. I am also going to replace the timing chains and tensioners while I have it apart as well as the motor mounts. The car is immaculate inside and out. Just curious if I should replace anything else major while I have this apart.

If the head bolts are centre popped then yes, if not then they can be reused.
New plugs can't do any harm and should aid initial mapping when the engine is fired up after the rebuild.
Why are you changing the chains and tensioners again if you only did them a year ago?
Has this engine had a problem??
I would also address the ongoing problem with your car's ZF gearbox, they're a hand grenade item but preventative work and fitting of one part along with a fluid change should see the issue gone. Do a search for 'transgo' within this forum for all the info you need to save thousands of dollars on a reman trans![Wink](https://www.jaguarforums.com/forum/images/smilies/wink.gif)
Hope this helps
