There is a gasket (oring) you need to get from the dealer. Have them print out a diagram of the oil cooler so you can see how it comes apart. Buy the gasket, remove the oil filter, remove the nut that holds the housing together(it will be at the base of the stud that oil filter screws onto, 27mm deep well), clean out the old brittle cracked o-ring and replace it, reverse disassembly, and smile because you were done in less than an hour.

You can get a replacement part that the oil filter screws into...usually its a series of bolts on the side of the engine and it comes off...and a gasket is between needs to be replaced when you do...its a tight fit but fixable

Volvo v50 t5 oil leak

Most likely it is the breather tube and/or the oil trap box (integrated into the oil filter housing). if the box is plugged or the diaphragm is torn the box will send oil to the top of the engine via the hose.

do you also have a high pitched whistling noise?

Volvo has extended the warranty for the oil trap box (filter housing) to 120k miles and/or 10 years.

Oil leak from oil filter housing

  1. First check and make sure the filter is not lose.
  2. You might want to pull the oil filter and check to see if the gasket has spit or if more than one was accidentally put on during the last oil change,
  3. Should that check out there then, with the oil filter off, take and try to rotate the housing itself a bit. Just see if there is some movement. If there is then there is a nut that you can tighten up. It the nut will be on the same bolt shaft that the oil filter screws onto. Sometimes when taking off a really stuck filter the housing can come loose.
  4. There are also two hoses attached to the oil filter housing. Make sure they have not ruptured or that the clap has not failed.

A ton of pressure goes through the oil filter housing. You don't want to drive the vehicle until this is fixed because all your oil can leak out rather quick and seize your engine. Regards, Tony

Oil cap and dipstick covered in creamy sludge, is this breather prob as not losing any water

Yes, it could be that a plugged up Positive Crankcase Ventilation (PCV) valve or engine crankcase breather (with filter) is the cause allowing moisture to condense in the crankcase. However, if the valve and breather are okay, a cylinder compression test should be done to verify that the cylinder head gasket is not leaking. Regardless, the engine oil should be drained and the engine flushed with clean oil and an appropriate crankcase flush additive. Entrained water in the oil (the creamy sludge) will damage engine bearings quickly.

I have changed pcv valve twice and still getting oil in breather

The PCV valve does not control the oil situation, it just keeps the pans and valve covers from blowing off during a backfire. Excessive Oil in the breather is a result of excessive crankcase pressures, usually due to a worn engine, specifically rings.
SOME oil is normal, especially if you are loaded heavily and hard on the throttle.
There is a tester that measures crankcase pressures, but usually some other manifestation shows, like excessive oil consumption.

the PCV system draws crankcase fumes into the intake at idle and lower throttle situations. air going into the crankcase is filtered by the small PCV filter, where the oil shows up....

At highter throttle and lower intake manifold pressures, the system reverses, the PCV valve closes, and the fumes exit the crankcase VIA the breather filter. All of this is normal.

It costs tons less to periodically clean or replace the PCV filter.

How do i repair oil filter housing leak?

The oil is most likely leaking from the oil cooler seal. The oil cooler is the square aluminum piece that the oil filter screws onto. To replace the seal, remove the filter, remove both coolant hoses that attach to the cooler, remove the nut that secures the cooler to the block and slide the cooler off the tube. Replace the rubber o-ring seal which is available at the VW dealer. It's inexpensive. Replace everything in reverse order. Good luck!

I was wandering if you might now why my air filter keeps gettin oil soaked

One of the first concerns is the health of the engine. Do we have a tired old engine allowing the blow-by gases to pressurize the crankcase? If so, the pressure would force the oil up the PCV breather hose and contaminate the PCV breather filter and air filter.

The Positive Crankcase Ventilation (PCV) System is one of the oldest and most neglected emission control systems. The valve is a calibrated vacuum leak controlled by a plunger and spring. Contaminates or changes in spring tension can directly affect the flow of the valve, which could result in oil accumulating in the air cleaner or an imbalance in the fuel mixture. Remember: For each gallon of fuel consumed by an internal combustion engine, one gallon of water vapor is created through condensation. Much of this condensation is formed in the crankcase. The PCV system is designed to control this condensation and remove gases which accumulate from the combustion process and collect in the crankcase, in addition to protecting the environment.

Conditions other than a defective or restricted PCV valve can lead to an accumulation of oil in
the air cleaner, sludge deposits, poor performance, or excessive oil consumption.
Check the following:
• The PCV and fresh air hoses are clear and free of obstruction
• The proper valve is selected for the application
• The valve is functioning properly
• The valve fits tightly in its rubber grommet
• Any O-rings or hoses are tightly secured to their mounting

There is a puddle of oil behind the throttle plate in my 97 land rover discovery.why? there is a breather hose that goes from the valve cover to the mantafold plenum is there supposed to be a pcv valve or...

My 96 Discovery has a plastic baffles inside the valve cover port that connects to the hose. If it got brittle and cracked, then oil could leak by. Its cheap and easy to replace, along with the hose. There is a second hose on the other side to replace as well. Land Rover was proud to pass emissions standards without using exhaust gas recirculation (EGR). The whole system is sealed, so all the air entering the engine is being metered by the Mass Air Flow (MAF) sensor, unless your breather hoses crack and leak. Unfortunately, oil in your location might also indicate other engine trouble, such as worn piston rings (causing pressure in the crankcase). I would try replacing the plastic baffle piece first.
