Subject basically says it all but in particular I was referring to blocked breathers leading to cam cover gasket leakage. If not, do 2.6 and 3.2's suffer any other problems peculiar to those models?

Happy New Year to all

They can suffer the same problems such as cam cover gaskets. The only additional regular problem that springs to mind is the 0420/0430 codes due to a failing cat, normally rectified by either fitting new cats at an exorbitant cost or moving the front set of lambdas back behind the 2nd cat.

Early ones circa 2001 were prone to valve stem seal failure

2.5's are actually more reliable than DBW 2.6/3.2 i would say, no coil pack issues, cat/o2 or which ever sensor causes trouble on 3.2, no stem seal issues.

To clarify, blocked breathers is not a 'problem' with the engine, given regular oil changes gaskets should last 5 years+.

And its still an issue on all other cars, eg chain drive, but has more serious consequences, like snapped chains!

Cam cover gasket on mine lasted until 115k before it needed changing

they are newer and more up to date is all really. C cover seals fail with age as well so that might make them more unrelisble on older cars.

the drive by wire engines have a more advanced engine management system, meaning they do away with sai and egr. DBW is also accurate enough at low revs to do away with icv. Head gasket is metal so less likely to fail.

ECU is smarter running obdll codes which will tell you which cylinder missfires. 2.5 3.0 wont even notice a missfire never mind tell you which cyliner. Pedal trick is easier.

On the down side, DBW and coil packs per cylinder are more expensive to replace if they fail. MAF seems less reliable than 2.5 and 3.0
