Hi – I am wondering if you mean the turbocharger pressure control valve, sometimes called a "pop-off" valve, may have failed, over-pressuring the engine? this could cause serious damage to many parts of the engine. The PCV (positive crankcase ventilation system) valve should not be able to effect the turbo charger or engine in this fashion. Since your vehicle is still under warranty, I hope the dealer is fixing this issue for you. If not, I would escalate through Buick Customer Service.

If the valve doesn`t open and close on schedule, or if any part of the system clogs, the result can be a rough idle, sluggish acceleration or increased oil consumption. Rough idling is commonly caused by bad spark plugs, so problems with the PCV valve are often misdiagnosed.
The PCV valve can get stuck open or clogged with sludge and should be inspected regularly and replaced when required. If the PCV valve is failing it can cause your Holden Commodore`s engine to run rough and you may notice some exhaust smoke and oil leaks.
When your PCV valve is malfunctioning, it throws the air to fuel mixture out of balance and can lead to poor performance and rough idle, as well as misfires. In the very short term, these issues should not damage your car, but if you don`t fix the issue, you can do lasting damage, so it`s best to get it fixed promptly.
Often various sensors, control valves, excessive internal crankcase vapors, or even faulty PCV valves can prompt codes for over and under boost conditions. Symptoms: Under-boost causing a loss in vehicle performance and an illuminated orange MIL (Malfunction Indicator lamp) with the P0299 fault code stored.
It is necessary to replace the PCV valve regularly. Most manufacturers recommend replacement of the valve as often as every thirty thousand miles.
A PCV valve that`s stuck open will allow too much air to enter the intake manifold, leading to a leaner idling fuel-air mixture. Stuck closed leads to a build up of pressure in the crank case which creates a variety of oil leaks! And this in turn can lead to a range of issues, including a rough idle.
Whether due to clogging or mechanical failure, a stuck or clogged PCV valve can lead to a lot of additional problems. Two of these that can cost you additional money include increased fuel consumption and increased oil consumption.
Another symptom of a bad or failing PCV valve hose is your vehicle will misfire while it is idling. This can be from a loss of vacuum due to the hose not working properly because of a leak, the hose being pinched, or becoming clogged from buildup over time.
A stuck closed PCV valve results in excessive crankcase pressure. It forces oil past the engine`s seals and gaskets. A stuck open PCV valve or leaking hose results in a large vacuum leak, a rough idle, and drivability issues like surging.
Leaking in the vehicle`s oil passages can also lead to low pressure. Internal oil leaks can be caused by a myriad of factors, including worn piston rings and valve seals or PCV valve failure.
The PCV system allows for cleaner exhaust, prevents blowby at seals and gaskets, removes crankcase gasses generated by the combustion process that will sludge up and destroy the engine if left unchecked, and allows the engine to run more efficiently thus creating better fuel mileage!
Will a bad PCV valve burn oil? No. A bad PCV valve will not cause your vehicle to burn oil. In fact, if you have a leak in the PCV system, it is likely that you will be losing some of the oil from the crankcase into the intake manifold and then into the combustion chamber.
Possible causes of low boost pressure can be broken hoses, contamination build-up within the turbine or compressor areas, leaking seals, damaged shaft bearings, the wastegate sticking open or operating incorrectly, a leak in the intercooler, a blocked air filter, a damaged diesel particle filter, or a damaged catalytic …
If the PCV system is not functioning correctly, it can cause the engine to ingest large volumes of oil droplets and crankcase vapors. Diverter valves can fail to seal and cause a P0299 code.
On some vehicles, a bad PCV valve can cause oil to blow onto the air filter element. An oily or dirty spot, near the PCV inlet hose is a symptom.
Can WD40 be used to clean PCV valve? WD40 can be used to clean the PCV valve but it is not recommended. WD40 is a lubricant and not a cleaner. It will do little to remove the carbon buildup and may make it harder for you to get the valve out in the first place.
Because PVC is immune to corrosion, a minimum service life of at least 100 years can be expected. This figure is supported by a number of independent studies, as well as the experience of many long-term users of PVC piping systems.
Yes, a bad PCV valve can cause some RPM issues.
Because the PCV valve controls the flow of blow-by vapors from the crankcase to the intake manifold, a faulty or broken PCV valve can manifest itself in the same way as an intake air leak. A bad PCV valve can cause the idle RPM to get too high and unusual idle behaviors like very rough idling.
A defective positive crankcase ventilation (PCV) valve or a malfunctioning exhaust gas recirculation (EGR) valve also can cause a backfire.
From the description you have provided, your vehicle`s bad PCV and coolant loss are not related. The PCV (positive crankcase ventilation) valve is designed to remove combustion gases that get past the piston rings into the engine. Typically, a bad PCV valve leaks or plugs, replacement is recommended.
