Resident Clubdub Debbie Downer. I'd love your ideas if you kept them to yourself. Subarus suck, get a new wife.
Never argue with idiots. They'll drag you to their level and beat you with experience.
Sooo.. it might be bent valves. I'm really hoping so bc then i won't have to split the block. The sound seems louder on top than from under the ebbing and its definitely on the left side. I took the left head off this morning so ill take it apart later and investigate. There was a time when i was putting on the timing belt that the cam gear slipped and the intake n exhaust valves hit eachother. The good thing is that it went super fast this time! And if its valves I won't even have to pull the engine out. Was able to get head off while engine was still in. Crossing my fingers
Under the engine.. . Not ebbing.. stupid auto correct. Happy thanksgiving!
best o luck! lets hope valves didn't contact piston and its just valves.

SUCH IS MANGO!
so, I think it is just the valves. i had an exhaust leak, and when i tightened it up, the noise was easier to hear. it seemed louder from the top of the engine than from he bottom, making me think it's the head. i took the head off, and when the lifters came out some of the valves looked like they were not exactly in the center like the should be. took out the valves, rolled them on a mirror, and some seemed to have a slight wobble. put them in back in their holes, and pushed on them so they had tension on them (trying to mimic spring force), and poured water down the holes. guess what.. they all leak! also, when i turned the crank back and forth after taking the head out, it seemed to feel just fine. no play at all when moving crank back and forth. i would think it would feel a little odd if i had spun a rod bearing, but who knows. interesting though, the fourth cylinder looked like it had never fired. when taking off the coil pack, the wire that plugs into it from the wire harness fell off, so it must have been loose! guess i did do some dumb sh*t when assembling, kind of scary. i was reading that bent valves can cause it to not fire, but the bad connection seems more likely cause for a no fire situation to me. and, this would obviously cause the car to run like crap. i'll make sure those are all plugged in good next time!
When putting on the timing belt, the cam gears have to be in that very particular spot on the left head that they really don't want to be in. they got away from me twice, and the intake and exhaust valves smacked into eachother.. so its very possible i wrecked them at that point.
Never thought i'd hope to have bent valves, but i do! would be so much simpler for this to be the problem than to have to split the block and pull the engine again. I was able to get the head off wthout taking the engine out of the car, which was awesome, and i actually got it stripped down and taken apart really fast by the end of this, i'm going to be like a professional wrx mechanic. i feel pretty confident about fixing a lot of parts on this thing now at least. it was helpful that i had remembered what all the sizes to all of the bolt heads were this time, haha. so i priced out parts today. i can get 4 new intake valves, 4 new exhaust valves, and 8 springs for $162. THey are closed for the holiday so fastest i could get them to me is next friday.
even if the knock sound isnt the valves, i think i will replace them anyway, since they were all leaking anyway with the water text. and put it back together and pray
Good luck.. Hhmm.. Weird how you got mad at me for suggesting you re-check coil packs

By the end of this I will pay you to help me work on my car!!!
No, haven't given up yet. I took the left head off, and valves out, replaced all of them, as well as all of the springs. Checked the valve clearances and replaced three shims. Put it back together and no knock! i had to replace an oxygen sensor as well.
My turbo doesn't work now. My acceleration isn't smooth either. Cold starts are brutal ( have to keep foot on gas to keep rpms at 1000 or it will die, for first 10 minutes). Probably bc of TGV delete, but I'm wondering how to adjust my idle so maybe I could turn it up a bit for the warm up period so I dont have to sit there with foot on peddle?
I have several codes, one of them being a TGV sensor high code. I left the motors, rods and sensors in place though. Also, when I first start the car, I have low oil pressure. If I rev it up to 1500 rpm or so, I get pressure, and the pressure stays til I shut off the engine. Not sure why this is happening. My steering feels weird, totally unrelated, but seems to be a new problem. Other than all of these issues, the car runs great haha.
The car is at a shop right now, I am getting real sick of dealing with it. It's officially really cold out now. I'm hoping they can tell me what needs to be done now.
I just took it for it's first test drive on Sunday morning. I would have been posting excitedly, but my boyfriend's brother's pregnant wife and baby died unexpectedly and really tragically, was a bit distracting.
