Hi all,
Ive had a Mann Hummel provent 200 on my 2007 yd25 d40 for around 7-8 years.
It has as always worked as it should, i was draining out around 50ml of oil every month or two.
Then one day around a month ago, the rig started blowing lots of blue smoke out the exhaust that smelled like oil.
I checked the catch can right away and saw it was pretty full, i probly should have drained it a bit earlier.
I thought bugger it, its time to replace the filter anyway, so i bought a new filter and replaced it, along with the oil lines into and out of the catch can, which were pretty mucky.
I also gave the can itself a clean.
So when the new filter arrived, it came with a little leaflet and instructions that explained that due to new emissions laws, the pressure relief valve must now vent internally, instead of releasing through the cap to atmosphere,
The filter itself now has a valve built into the bottom of it, and the original relief valve that was built into the lid of the catch can must be removed and a blanking cap installed.
I did this and thought sweet all done no worries. I also checked some vids from reputable installers on youtube to make sure I was doing everything right.
But ever since this was done, i get some (not a lot but some) blue smoke on idle when the engine is warmed up, and now i get mainly water out of the catch can instead of oil.
Ive checked all the lines, the hose clamps, the filter installation, the catch can cap, everything i can think of, but i still get some blue smoke and mainly water out of the catch can every week or so when i check.
Ive tried taking the filter out of the catch can entirely, and that does stop the blue smoke.
But i dont want to remove the catch can so need to figure this one out.
Any help much appreciated
