Re: Nissan patrol 3.0l TD vs 4.2
dazza,
i have a 3.0td. They both have similar power levels but drive very differently. If your doing a lot of towing get the 4.2, its got a great reputation for reliability and will do it easier. 4.2s are hard to find
As for the 3.0td, theres issues on their engine reliability early on ( 2001/2002 with a lot of motors blowing), 2003 onwards Nissan did a fix. On some general 4wd forums, scaremongers reckon its still a timebomb waiting to go off etc but on the specific nissan patrol forum you will get a lot of info/surveys etc....which shows the true picture, ie problem fixed ( considering how many 3.0tds running around now in Navaras/Patrols).
Also mind you there a plenty of 2001/2002 models still running around with high klms now, but like i said your best not to look at those.
Ive driven both, if you do mostly blacktop, some beach and off road then the 3.0td is fine, if your doing a lot of towing id go the 4.2. Both are great trucks. The 3.0td has a bad rep from its early problems and i suppose the jurys out for a few years until some trucks get into the 300/400 klms but can you wait that long?
cheers
mike
