2001 S80 engine oil leak or blowing oil out

Bruce Nussman · Post by **Bruce Nussman** » 02 May 2016, 07:01

Have had oil leak. Volvo dealer advised cam seal leaking $1200, or may be caused by air box $850. Drove 65 miles and leaked or blew out 3 quarts of oil. Is there a way to flush out air box? if so how and where is it located?

Thanks

are you saying there is oil in the inlet filter box? Is the car down on power? T6??

Mine does the same thing. Oil dipstick gave a low reading, poured 2 quarts of oil, drove about 60 miles and now the car won't start. Took it to a mechanic and there's apparently a wiring fault. Oil has definitely sprayed onto something. Let me know what you find so I can do the same

Had camshaft oil seal replaced $340. Volvo dealer wanted $1200. Now have engine light code Poo11.

I have a 2000 S 80 2.9 i inherited a few months ago. IT WAS in bad need of a lot of different repairs. I have taken the challenge to do all needed repairs myself being a machanical engineer and master tech. close to 40 years, but at the time i knew nothing about Volvo had never worked on Volvo had neven driven one.
This past weekend i replaced water pump,timing belt , serpentine belt ,all tensioners rollers
I was rather comprehensive about doing the job after reading so many stories from others talking about the difficulty of the job. I had no problem at all doing the work myself and actually i think Volvo has been one of the easiest cars to repair.
But i have one more job to takeon with the S 80 2.9 non turbo, that being the PCV system. I haven't been able to get much information about how this system works but sounds like it's not a good PCV system. I need to find out more about the system because right now i don't know where or how it is plumbed or what parts or where it is located.
I may do a little re engineering to the current PCV system.
I have already done that with the air intake system, running much better now that it can breath fresh cool air.
Is there specs.and diagram for the PCV complete system i can study before I tear into it this weekend.?
Sorry about the long rambling story ,i do need information on the PCV , it seems to be a problem, but I think if you keep your oil changed, engine tuned and take it out for a drive on the highway once in awhile, PCV shouldn't be a problem to the point of blowing seals and oil. I was wondering how you're spark plugs look and what does you're compression check show.and how much if any motor oil is getting into the throttle body? Must be a common denominator. Find that and repair or you're problem will only return later on.
You can check out the engine with a simple vacuum /low pressure gauge that you may be able to connect at the dipstick tube, pull out the dipstick first small piece of hose or rubber grommet connect gauge and if you are reading pressure you have a plugged up PVC system if you have vacuum there's no PCV problem.
Thanks in advance
Randy

you can get complete PCV service kits from FCP or IPD
requires removing intake manifold
pretty easy job

you can also put a nitrile glove on the oil fill port to look for vacuum or pressure
