Aston Martin Valvetrain

Last year we changed a piston in the AM engine but its still not in the car. Lazy! There is hope, last week we set valvetiming and valvelash. Complicated and not very service friendly, there is no adjuster at the cam gear, it must be set with an excentric gear resting between intake and exhaust cam. So you have to set everything at once, intake timing, exhaust timing, overlap and not to forget chain tension. Maybe the Aston engineers wanted to take care of the assemblyworkers so that they earn enough money from workovertime to feed their families.
