Ok, so after I spun a rod bearing in my ej22t/25 hybrid motor in january, I finally decided in august to just put the Phase 1 2.5 back in my legacy so I could run low boost and have my car back. Well, I put it all back together, and Now I have a bad noise coming from the motor. Basically, it sounds like your typical Subaru Cold-start piston slap...but louder...and it doesn't go away when the motor warms up. At first I thought it was just because I started the car on a WRX basemap (so 2.0l @ 8:1 CPR Vs the 2.5l @ 10:1 CPR motor that's actaully in my car) but I'm thinking more and more there's something wrong mechanically. So, who has some Ideas what I should do?
it MAY be your heads arent all oiled up yet, drive the car for a while and see if it goes away. does it sound like this? . thats heads if it sounds like that. you could also take a long screwdriver and listen to the heads then listen to the block on EACH BANK of the motor.
indeed if the heads arent oiled up yet it will take a few trips to almost redline to get them filled, at least thats how it is on my 2.2
It shouldn't take long to get oil to the heads. These engines does not use hydraulic lifters like mitsus. Does it sound like its knocking?
Its a '98. If there was too much timing it wouldn't idle for beans. Basically, if the mao was that bad, you wouldn't be able to get it to idle very well. Its not going to knock at no load like that, and even if it could, it would be a light "tick tick tick," not sounding like nasty piston slap.
Timshow, I love you. Yes, my car sounds almost identical to that WRX video. I'm gonna go start it up and listen with a screw driver
what is your turbo kit setup? and what EM? or since you are only running low boost do you even need to run EM? will the computer even find out?

yea i know i saw that i was reading it but my question more or less was if i did or could find a used custom turbo kit on rs25 or nabisco made for N/A's and i only wanted to run 5-6 psi would i still need some sort of EM or can i just run that low amount of boost on my stock ECU with a mild tune?
agreed, the valvetrain will make some noise for a bit. much worse on the HLA setups, but still present on others. do you have an oil pressure gauge? FYI, technically they're not lifters, but hydraulic lash adjusters (HLAs).....
so... after putting a screw driver to it, Kalie and I think it's louder in the heads (well atleast higher pitched) and Pete and Jamie think it's in the block...so idk I don't have the oil pressure guage hooked up, because i STILL haven't ordered a sandwich plate for the oil filter... ...so chux, when are you free this week to come listen haha?
you could hook a generic gauge up to the oil pressure sender (right under the alt) it should give you an idea.
^ You can do that or you can drill out and tap the plug on the back of the main galley. I'm sourcing my oil pressure gauge from my turbo feed.
I can T it off my Turbo Oil feed? I didn't think that was allowed. Besides hooking up the oil pressure gauge, what should I be doing? or trying to figure out?
I'm not sure what kind of pressure you'll make in your feed line with a journal bearing turbo flowing much more oil. My turbo needs the .035" restrictor, so I still make pretty high pressure there. There are different theories out there as to where one should put the pressure gauge source. Some say off the main bearing oil galley. Others say farther back in the system so you can see if there are other problems. I put mine where it was convenient.
Well I'll probably do the same..I just have to figure out where that is...Still probably gonna get a sandwich plate eventaully. Well my friend brought over an engine stethoscope tonight, and I tracked the noise to the Passenger-side Intake Cam (most specifically the Front half). Interestingly enough, the first time I put these heads on the 22t, I snapped one of the Cam Cap retaining bolts and retapped the head with a 1/4 fine-thread bolt. So I'm guessing that has something to do with it...so I'm gonna take that valve cover off and see what I can see...
I see something in your future. Its coming to me..... My crystal ball is shopwing me a picture of a couple torque wrenches.
