Hi
Thought I would ask a car related question.
I just picked up a vz for $1500 as a non runner, 164K on the clock. It
was said to have an electronic fault ( can bus dead). Had it towed to a
spakey I deal with and the thing checked out OK. It turns out the cam
chains are the problem. Looks like I may be doing this one myself. I
have a book coming and will hold off ordering the cam kit until I have
striped it.
The motor is the LEO, There are cam tools listed in some of the kits
to line up the cams. Are the tools needed or is it just a case of lining
up the marks as with almost every other engine that I have worked on
(normally heavy diesel). Also do the 3.6 Alloytec's bend valves if it
has had a big failure or are they a clearance engine.

The procedure outlined in post number 7 of this thread will help you:

They're known for timing chain failures, and bending valves as a result.
If yours has a timing chain issue, you can bank on both the heads
needing to be removed and repaired.
By the time you factor in the cost of both a timing chain kit, head work
and the time to do it all, it may be cheaper and easier to source a good
used engine.

Here's a tip, if you still can't get it running, disconnect the ABS

connector. A certain fault mode of the ABS module has been known to kill
the CAN-bus but not show up as a fault.

You might do better to source an engine produced from 2008 onwards if it
comes to that.

Got the front off tonight and it looks bad. I have never seen so much
sludge in a modern engine. Looks like it has been running cheap oil and
not been changed for the last 100K or so. It has had a back yard chain
replacement including guides. They just scraped some of the muck off the
covers, Threw the new chains in DRY and changed the oil.No gaskets
replaced and I dont think the engine has ever started after the repair.
Only good news is it has compression on all cylinders so most likely no
bent valves.
Looks like a long or short engine may be the go. I will drop the heads
off on the weekend just for the hell of it.
By the way if any one has an engine in the Adelaide area let me know

Low mileage, and it's even in your part of the country.

As for running it, It is that sludged up I would not be game to try
without striping and cleaning the sump and oil gallery's. Cheaper to
just replace it.
It was tying to fire before I striped it, Had fuel and must of had
spark, I did not check anything after I heard the front rattling
