2002 Subaru WRX Hatchback
Hey I'm new to the forum but could use a little help. I was driving the car and everything was normal, but then she started running real rough, nothing abrupt, but I hadn't noticed anything the previous day.
She definitely isn't firing on all 4 cylinders, white smoke out the tail pipe, but only sometimes, fluid levels look good, and this is gonna sound weird, but an occasional *chirp* sound from the tail pipe every 10-15 seconds, again only sometimes.
I changed all the spark plugs (but didn't verify correct spacing) because that's what worked the other year. The two drivers side were good, the two on the passenger side were fouled. I replaced them, the car ran normal again for about 15-20 seconds then back to running rough as before.
So here's the meat: I got a guy to look at the car and he performed pressure and leak tests on one cylinder for each side of the engine:
Side 1- Pressure: 105 Hot, 90 Cold - Leak 26%
Side 2- Pressure: 105 Hot, 90 Cold - Leak 10%
He also found a potential culprit, a big gash in the deteriorating rubber coupling at the intake to the turbo. The mechanic is thinking this is the cause, dirty air into turbo and engine causing engine damage, RIP car (not worth rebuild at this time)
I'm not a mechanic and don't have a lot of experience, but just wondering a couple of things. Wouldn't unfiltered air cause only gradual damage to the engine? This problem occurred rather quickly and power was fine prior to this issue. This wouldn't be a gasket issue b/c pressure is equal in both cylinders, right?
I'm just having a hard time letting go of this car because I don't quite understand exactly what is wrong with the engine. Any help in reading into this would be appreciated. Thanks!
