This must be one of the most frequently posted questions :biggrin:
It sounds like you are describing the failure/weakening of the timing belt hydraulic tensioner (or pusher).
The Isuzu V6 uses a belt (not a chain).
The following link has much info - just be sure that you note that there are some differences between setting the cam timing marks on the SOHC and DOHC motors - otherwise everything else is pretty much the same http://forum.planetisuzoo.com/viewtopic.php?t=16972
Here's my SOHC how-to: http://forum.australia4wd.com/index.php?showtopic=7463
Download also available at http://www.datazap.net/sites/Australia4WD/Forum%20Articles/Isuzu_V6_Timing_Belt_and_Water_Pump_rev2.pdf
Also search the Isuzu forum site(s) for tensioner or pusher.
All the best :wink:

Thanks alot man, I guess I will be changing it myself even the parts look costly

No worries mate - you're welcome.
Just another thought - I re-read your first post and noticed that you said the ticking noise goes away. The 3.2 V6 is prone to hydraulic valve lifter noise - somewhat like the sound of a diesel motor. Can be minimized by regular quality oil changes. Timing-belt tensioner noise reduces as the revs increase.
Back to the timing-belt: the recommended replacement schedule is around 100,000 miles, so if yours hasn't been done yet it is due anyway.
Replace the belt, idler pulley, tensioner pulley, hydraulic pusher, and water-pump - all of which are in the belt drive-train.

I have 107,000 mile so I am going to change everything and the oil it looks pretty dirty. I don't think it has been changed in a while so I will change that and see what happens. A mechanic told me that if you break a timing belt you will bend the valves. Have you heard anything about that happening? It may be a week before I can get to it.

The 3.2V6 is a non-interference engine (the pistons will not clash with the valves regardless of cam/crank timing). You need not worry about valve damage if the belt breaks.
It could possibly damage the plastic covers if it did break.
