took off the the engine cover to get to the vac line to do seafoam and there is oil everywhere under there. wtf is going on. also when i removed the turbo side of the CAP there appears to be on and around this connection as if it is inside the CAP. please someone let me know what is going on here. pictures up in a minute.


this pic is fuzzy but you can tell there is oil on the CAP connection at the turbo

Without pictures I am guessing the PCV has gone bad. Its also possible the gasket under the oil filler cap is leaking.

Take a closer look at the PCV hose with the Blue Dot in your picture. Friend had a constant leak on an 850 at that spot. Looking at the picture, it sure looks like the Oil Filler Cap gasket is leaking.

When I first got my R, I had the same problem you did. First thing I did was change the oil seal and the problem was gone. :)

Possibly 8692217? As its listed as cross reference on the iPd Site. When you zoom in on the picture, thats the part number on the Volvo sticker.

PCV breaking in the position where this one is broken will not cause oil to be under the spark plug cover. A bad oil cap gasket will cause that. You should order plugs too while you get the PVC system done. Your spark plug holes should be filled with oil too. Your #3(middle spark plug) cylinder spark plug hole should be the most filled with oil and then gettign less and less as you get further away from the oil cap.

this is the hose that broke

take a picture of everything before you remove it so you can reference it if you have to later

un plug all the coils and move them out of the way, un do the 10mm bolts that hold the grounds down on the harness. then un do the 10mm holding the coil in, pull it up and it should POP out, once it is out use good old fashioned bounty paper towels and cover the spark plug hole. use compressed air and blow it in there while you have it covered, or else oil WILL get everywhere!! i changed the spark plugs while i was this far into it too.

why does my car run with this hose broken? sorry PCV system kind of a mystery to me
why shouldnt it? the reason for this system is to release Positive Crankcase Ventilation. its just to release pressure from the bottom of the engine to the top of the engine and vice versa. So when it is clogged it creates too much pressure at the top thus blowing out the front and rear cam seals, and on the bottom it blows out the rear main seal. Its a important part of a engine, since it is cracked probably due to age not for mileage. now it just vents out to the atmosphere all the time, which is illeagal...EPA goverment crap LOL

No, you are just venting any crankcase pressure to the atmosphere. Emission regulations require those pressures to be reentered into the engine instead of just being released into the atmosphere. Basically its just as if you are driving with your Oil Cap OFF.

Is it not letting in unmetered air as well, since it ends up going back in the intake past the maf? Or is there a valve or something that would keep that from happening?
