Ihave just purchased a jato 2.5 and i am reading a lot about engine rebuilds. i was just wondering how often the engine needs rebuilding and what needs replacing.
Another thing i was wandering about was if it is normal for my car to roll forward freely when it is not running but it has resistance when you try to roll it backwards. Also if any one has any tips or tricks for me regarding the jato please feel free to share them with me. Thanks.
you need to rebuild the engine when it needs it. as simple as that. in the engine manual (it dosent say it in as much detail in the jato manual) it says to replace the connecting rod every 3 gallons, or replace it with the piston/sleeve, which ever comes first. it says on page 40 of the jato manual about when the piston/sleeve should be replaced.
and yes it is normal for your car to roll forward easy, but harder to roll backwards. the reason is theres a one way bearing in the transmission needed for the second gear to work without stripping teeth when it tries to change to 2nd.
Your break in will determine how long your engine lasts. If you followed all the rules, you should get 8+ gallons before a rebuild.
