Thread: Provent 200 outcome after 150,000km

Thanks, interesting. Have seen similar results in the marine and stationary engine applications, I have been disconnecting the crank case breathers and fitting various types of catch or diversion systems to prevent the issue you describe with varying levels of effectiveness as some of these engines require something about 6x the size of the provent system if not more. Some of these engines ended up with a setup the size of a 40L container to baffle and condense the oil vapour out effectively. Effects of blowby ingestion are a lot more visible on a marine or stationary engine where you can see exactly what is happening when the engine is running - mostly in the intake filter turning black...

I'm also about to do this to my ranger ute, having decided to retain it rather than replace as it's about $10,000 cheaper to run in fuel burn cost only per 100,000Km than the equivalent vehicle with a 6-speed automatic transmission. That will be getting the DPF sorted, the EGR blanked (have investigated this closely and it is the recommended option for the ranger engine partially due to the fact that the cooling system is routed through the EGR valve, deleting the EGR setup allows you to blank the EGR cooling system off as this is a known weak point that will cook the engine if it fails). Also the vane oil pump replaced with a gear pump. As well, the injectors pulled and tested and any issues sorted (injectors replaced if needed) as we just pulled the pressure sensor off the common rail and found it to have been fouled by the factory thread sealant with crumbly debris jammed in the end of the sensor! Not ideal, not sure where else the failing sealant might have traveled too... I had a camera up the manifold through the EGR, and have not seen much in the way of buildup of any sort - evidence of more hot running than short trips.
