Hi all, i have recently purchased an 03 zd30 patrol and its great but its hard to take when some mechanics say sell it now b4 it bites you. It only has 128k's and great service history. I dont want to sell it because i already love it. I know all of these topics have been covered b4 but was wondering if the dawes valve, catch can, egt and boost guage plus blocked egr are still the best way to look after these engines or is there some new device? I have only installed a boost guage so far and has never gone above 16psi yet. Where is the best place to buy all this stuff? Or should i just listen to the mechanic and buy a cruiser? Any advice is appreciated.
