Hi,

I have been having an issue with my 2005 Volvo S80 2.5T 5 Cylinder FWD. I had the engine replaced due to a catastrophic failure due to oil loss at 100,000 miles. The new engine had 103,000 miles, and after a year of driving it is at 113,000 miles. The new engine set-up has been losing oil excessively without leaving oil in my parking spot. There are three separate issues I outline below, and I am asking for your advice on how to go about correcting these problems.

If the images are not working below, they are also available here:

There appears to be an excess of oil in the intercooler system (pictured below, (1) collected in the lower elbow of a hose, and (2) coating the inside of a hose.





In addition to the intercooler problem, the PCV system appears to be faulty as well. I had smoke coming out of the dipstick tube, and oil cap. After attaching a glove to both, they were not sucked in, but flapped about at idle, and after revving the engine to 2000 rpm. To access the PCV system, I have removed the intake manifold as pictured below.



Also, there is a build up of sludge and oil next to the passenger side wheel well, as pictured below. I don't know too much about cars so I don't know what to think of this.




There is oil spatter and sludge all around this region, and I pulled off this rubber part that I also took a picture of below, because I was not sure what I was looking at.








I was not aware I was burning/losing oil until 3,000 miles after my last oil change. I filled the engine with an additional 4 quarts of oil, overfilling it by a quart, and drove 300 miles home for Winter break. Since then, the car has been burning oil to an extent that it is smoking and coming into the car through the lower vents. I'm not really sure what I'm dealing with, and I wanted to do my own maintenance on the car. Right now I have it up on stands with all the oil drained.

What do you all think of this situation? Do you know what could be going on with my car? Any advice or links to more information would be appreciated thanks, I will follow up on how the repair goes.

 

First off we can't see the pictures so I can't help me you with the pictures. But the faulty pcv would cause the excessive oil in the intercooler. The sludge in the wheel well sounds like a CV boot once again without looking at pictures.

 

Hi, Sorry about that, I actually can't figure out how to properly get the images to display, but I did include a link to an album of the images in my post.

Alright the pcv needs to be system needs to be cleaned and that includes cleaning the holes in the block thoroughly. If those aren't cleaned right the system will become clogged sonnet than normal. And if there isn't a physical cut or tear in the CV boot it is normal to see grease coming out the edge of the boot .

 

wow those are some crazy leaks. these are very common problems with volvos unfortunately. Thats good that you are doing the right thing on cleaning the pcv. i have a same 2.5T engine but a 2006.
Just wondering how/when do you do your maintenance like oil changes and other fluids.
it seems you are very comfortable working around the engine why dont you do a step by step procedure (like a video) on cleaning the pcv. It will be helpful for other owners.

I have just reached 100,000 mile and i have found this minor leak: been there for some time .

 

I have the exact same problem on the same car a 2005 s80 2.5t I changed the pcv but it still has white smoke out of the oil cap and dipstick and sometimes will start squealing at an idle. If anyone finds out how to clean the block ports please let me know. Thank you
