Since I started this journey trying to get the Comet running (fast) I´ve encountered all sorts of strange things but this one does it... Is there any possible way that you would gain anything by completely blocking of the PCV valve with a piece of wood and run without a thermostat...? Just asking since there maybe be somekind of trade secret here that I don´t know about..? I´m thinking maybe there is some other problem someone has tried to "forget" about and done these "modifications".... Thanks! Robert.
You need a PCV valve that will allow the engine to breath. A plugged PCV will push oil through the rings and gaskets. You need a thermostat that will keep the engine running too cold...a cold engine will wear out faster than an warm engine (175*-195* preferably)
