What causes Ringland failure STI?
Why Do Subaru Ringlands Fail? Anything that promotes detonation such as low octane fuel, lack of proper tuning, and prolonged hard driving can potentially cause piston ringland failure. Detonation is when the mixture auto-ignites and forms an additional flame front in the combustion chamber.
How long do Subaru Impreza WRX Sti last?
The life of a WRX can be 60,000–250,000 miles and most often in the 110,000–180,000 mile range that is usually when you see problems with the turbo. There are habits that any driver of a turbocharged performance vehicle needs for it to have the longest life possible.

Is there a problem with my Subaru Impreza?
Subaru Overheating!!!!!! Right I have a problem with my impreza (2003 blob eye with 59k miles on clock), there seems to be an intermittent over heating problem. It started when we had severe snow/icey weather, the car was working fine but all of a sudden the temp guage jumped to just under the red.
What causes detonation in a Subaru WRX STI?
Detonation is when the mixture auto-ignites and forms an additional flame front in the combustion chamber. This spontaneous ignition causes the flame fronts to slam into each other and produce a pressure spike well in excess of typical combustion.
What causes piston gap on Subaru WRX STI?
Piston ring gap is also a growing concern with the more recent motors. The gap is tight from the factory which makes the primary compression ring prone to binding. Binding occurs when the ring heats up and runs out of expansion room. The ring then flexs and puts a point load on the piston ringlands.
What does a oil pick up do?
The oil pickup is a tube that extends from the oil pump to the bottom of the oil pan. This action allows all oil taken into the pump to come from the surface This design prevents the pump from drawing oil from the bottom of the oil pan where dirt, water, and sludge are likely to collect.

How many miles do Subaru STIS last?
Can an oil pump get clogged?
Oil pump pickup tubes are not easy to replace. Chances are very good that if the oil pressure has dropped due to a clogged pickup tube screen, the pump is damaged and should be replaced along with new crankshaft bearings as well. There is a procedure, though, that may help if the damage is not too severe.
What controls the pressure in the oil pump?
pressure regulating valve assembly
The oil pressure is controlled by bearing tolerances within the engine and the pressure regulating valve assembly in the oil pump.
Are there any issues with the Subaru WRX STI?

What causes a Subaru WRX engine to misfire?
Spark plugs and ignition coils are without question two of the most common causes of WRX misfires. Leaking or faulty injectors may also cause misfires. Finally, newer direct injection (DI) Subaru engines can have misfires due to excess carbon build-up. Carbon build-up usually isn’t a problem on the WRX until close to 100,000 miles.
