How do I keep the pcv valves from freezing on 2003 dodge 1500 with 4.7L eng. This happens @ around -35C. When they freeze it pressures up the crankcase and blows all the eng oil out.
Contact your local dealer. there is a technical service bulletin tsb 25-002-08 that give a list of parts to repair this situation and a description of how to do it

The PCV valve is inserted into a grommet in the left side valve cover with a hose running to the intake manifold. On the right valve cover is another hose running to the ducting from the air box to the valve body - the PCV valve is not on this side.
I'm assuming you got this fixed already but to prevent it from happening again keep fuel more than half tank and with every fill add a fuel additive that prevents freezing
Hi there: Are you ferer at DTC P0410 - Secondary Air Injection System Malfunction
If this is right, this code refers to the emissions system. The AIR pump puts air to the exhaust to lower emissions. It takes in outside air and pumps it through two one-way check valves into each bank of the exhaust.
About 90% of the time that this code is set, the one-way check valves have worn out or failed and allow water (which occurs naturally in the exhaust) back into the pump. In any cold climate, especially in climates with higher humidity, this water may be more excessive. The water partially fills the AIR pump, it can then freeze. When the PCM commands the pump on, if the pump is frozen it cannot turn, thus overloading the circuit and "popping" the fuse.
A code P0410 may mean that one or more of the following has happened: Water may have collected in the AIR pump or the vent solenoid and frozen or corroded the pump Blown AIR pump fuse due to freezing up
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
Check your Fuel Filter, especially if your in a cold climate that has already reached freezing temps. If you have any moisture in your fuel system and the freezing temps have arrived the filter and injectors can freeze up slightly causing this type of problem. If this was happening in warmer temperatures check the fuel system for pin hole leaks that could be allowing the air into the system.
looking at the engine from front it should be in the right valve cover. a hose comes from the pcv valve to throttle body.to replace it, just pull up on valve to release from rubber grommet. have a good day !!
