For any engine with an oil pump, the components inside it are designed and engineered to operate at a certain range of oil pressures.
For example, an automobile engine might be designed to operate at # 30 to # 70 pounds of pressure.
If you subjected the bearings to double the pressure, you could achieve bearing failure, as you could with not enough pressure.
The oil pressure relief valve will "open" when the upper limit of pressure is reached and allow the extra pressure and oil to go straight back to the crankcase.
There is a relieve valve inside the part that holds your oil filter. It sounds like it may be stuck open which causes too much oil pressure to be relieved on the filter causing it to blow. So this art needs to be taken off and inspected.
The pressure relief valve is built into the oil pump. What you must do is have the area around the leak cleaned of all oil and dirt, then get under the car and try to see when the oil leaks where it seems to come from, I think the sending unit is around there for the oil pressure, it may be the problem, but do the cleaning 1st.
Filter is behind fuel tank , requires quick connect tools on inlet. they can be perchased in part stores. the other two lines just require a couple kus words but just depress the blue & green tabs too remove lines. releave fuel pressure at engine compartment test valve on fuel rail to injectors first. it will still make a mess.
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.
replace the pcv valve in the truck.located on the valve cover,it gives the crankcase positive crankcase ventilation. sound like yours is stopped up.when you replace the oil filter,use a thin film of oil around the oil filter gasket before you install it. you'll find that it helps to seal the oil filter perfect.thank you for choosing fixya.com
This issue is caused by crankcase pressure issue.
Normally filtered air enters the engine, runs through the crank case and then is pulled into the intake through the PCV valve. Durning hard acceleration, the PCV valve closes (to prevent explosion of fumes in crank case and blowing valve covers and pan off) and the PCV system reverses, with fumes coming back through the filtered intake.
Usually there is minimal oil that gets back into the air cleaner.
So, when somthing goes wrong, like excessive blow by, for example, the crankcase pressure overcomes the PCV valve and intake of fumes capability, and oily starts showing up in the air filter.
Investigate the crankcase pressure and PCV system.
