    Default Exhaust Removal System

    Has anyone experienced any problems with the turbos on their apparatus after the installation of an exhaust removal system? The system we have is the Plymovent System.

    We have a system very similar to PlymoVent and have no problems with vehicle performance.

    What are the engines that are having turbo problems? What are the problems? Since the turbos are most likely engine exhaust fed, IT would stand to reason that the station exhaust system could effect them. This is may not be the case however, The exhaust system is closed and no air can be drawn through the turbo by the exhaust system if the engine isnt running. If you are experiencing bearing failure in the turbos it could be due to early engine shut down or gunning the engine and shutting it off. This causes the oil pressure to cease before the turbo stops spinning. This will cause excess bearing wear. The only other types of problems that the turbo could have are float problems due to the turbine being unbalanced from the constant pressure from the station exhaust system. Also due to back pressure. But it is highly unlikely.

    We have a Plymovent system - no problems at all with engine turbos - there are 5 apparatus on the system (all turbocharged). A few problems with the Plymovent though - mostly pressure switches going bad and failing to start the blower.

    I am not aquainted with the exhaust system you are speaking about. My first reaction is if an exhaust blower is on and hooked to the rig the air flow is probably turning the turbocharger. Lubrication oil is not present as the engine is not running. This would result in premature bearing failure. Two cents worth of speculation.

    Regarding the Plymovent systems... I am a career firefighter with the City of Erie, PA as well as a vollie with Kearsarge FD (just outside of the City). We have had no problems with turbochargers on any apparatus in any of the six career station or the one vollie station. There are four other vollie stations outside of the City with the Plymovent system and no turbocharger problems have been reported from them as well. Personnel from Detroit and Cummins diesel have told us to idle the motors for approximately 4 to 5 minutes after backing into the station (obviously we attach the yellow & black hose while entering the apparatus bay). This will allow the engine oil to drop back into the oil pan and not remain in the upper section of the motor.
    This has worked for all of us in the Erie area. I hope this is a help to all of our other brothers out there. Keep yourselves safe. It better to talk to you than talk about you.
