Hi Nick

I will do the Job next 2 day’s when I’m in a Marina and will observe the result. After 2 weeks I’m happy to let you know the outcome because I will not move the boat until end of month.

Kind regards

Hi Ruedi,

After reading your email I had a quick look at the workshop manual for my D3 110A. I also had a look around the internet. I just thought that before you go and get an engineer you could do a few things yourself.  The Pressure Control Valve is located in the cap of the oil filter. The idea is that if the filter gets clocked the valve opens and lets the oil circulate freely but without being filtered. 

Trawling the internet, there was a suggestion that clogged oil lines and clogged filter might cause oil in the air filter. Seeing as that is an easy do it yourself, it makes sense to do that job first, not least to rule it out as the problem.. Then if that fails you still need to sail somewhere where there is a decent engineer and you can explain that you have clean oil and filter and cleaned up valve…

Let me know what happens. Great learning process for all of us!

Kind regards

Nick

Hi Nick,

Thank you for your advice. I will certainly do an Oil- and Filter change and clean the top cover.

What is the PCV Valve? Is this a specific part of the Oil-Filter top?

Ruedi, another quick thought. Take off the oil filter top and inspect it closely, maybe it is clogged. Could be you just need to give it a thorough clean, maybe in some solvent. Or blast it with compressed air. Then change oil and filter anyway. If this does not solve the problem you have not lost anything but a bit of oil and a filter…do not forget to torque up the filter top to specified level. I use a torque wrench, it is plastic and does not want to be over tightened but if too loose the oil will flow out and make a mess.

Hi Ruedi, 

I am not a qualified Volvo mechanic either, but  you must be getting some blow back. This could be caused by dirty engine oil clogging the oil lines or filter and/or a leaking Pressure control valve.

I would change the oil and filter and the air filter, and the PCV valve.  I do not think they are expensive. Located on the oil filter cover, opens if the resistance in the filter is too high. It could be stuck open or clogged. 

 

If that does not work you need to have a compression test done by a proper engineer…and get to the bottom of it…

Dear Amelia’s

I’m not a Diesel-Engine Mechanic or Engineer and therefore excuse my unqualified question. I have discovered Oil dropping out of the Air-Filter on my Volvo D3-110 iC and I’m not sure if this is something unusual and I have to worry about it? I changed the Air-Filter about a year ago and maybe this happens after several hours of use.

 

Thanks, and fair winds
