Wow, that's a lot of oil...

[legacy92ej22t]

Well I started getting ready for Subarina's heart transplant and as I started taking the intake tract apart I cannot believe the amount of oil that is in EVERYTHING. My positive crank case pressure must have been through the roof! Even my boost gauge's vacuum line has oil in it. Every time I took something apart it was like the car was pissing hot liquid shit all over me, kinda like the story Laurel posted. Hehe. I was suprised though as to how much oil was in everything.

The good news is that when I drained my oil from the pan I did not see any noticeable metal fragments. *fingers crossed*

The bad news is that I think I might have walked or spun a bearing or something because I have the loudest knock I've ever heard on #1 now too. I won't know for sure until I get it all the way out and tear into it but I sure hope the block is ok.

I have the motor pretty much ready to pull out. I just need to drain the coolant, pull the radiator and seperate the tranny and I'm ready to go.

I forgot to document my progress so far but I'm going to try and stay on it from here on out and will start a thread about the swap and condition of the old motor as well as the rebuild.

Good man, Matt.

I might be able to come up sometime when you get ready to finally drop the engine back in.

Remember this sticky on engine pulls

Cool, Matt... Get Subarina running good again!

I wonder if some of the oil can be attributed to the way you had to rearrange the PCV lines with the 16G install. In this picture:

It kinda looks like you used the same size hose for both of the top fittings of the F-pipe. Maybe switching to a smaller hose for the smaller fitting would help.

I got a lot of oil too, i wonder if its not only my turbo that is leaking. My engine is freshly rebuilt.

[dzx]

Probably excess blowby I have a lot in my intercooler pipes

[free5ty1e]

yeah, the blowby is significant... until I spent some time with my friend and traced the path the oil kept coating, and finally figured out which line was the one that I needed to reroute somewhere out of the way with a breather filter on the end of the hose. Since that time (and after I cleaned the oily piping with some brake parts cleaner) the entire intake from air filter to throttle body has been nice and dry. I can take a photo this weekend and post it if someone's interested to see which line, if you've got a coffee mug in place of your resonator or are thinking of doing that its nice to do this at the same time as well as adding a boost controller as this reduces the number of fittings you need on your mug. And Boot B can be replaced not with a $100 Subaru-Only replacement part, but with a 90 degree bend from some molded radiator hose plus a cheap exhaust adapter from Discount Auto Parts, and your stock BOV can then be run atmospheric without any noticable side effects (and thats another fitting you don't have to install...)

Phil- Thanks man! I totally hope that you and Vikash can come for a visit when it comes time to do the actual swap. That'd be sweet.

Vikash- The hoses are two different sizes, they just look the same.

Chris- That would be sweet if you could take a pic and post it. I'd be nterested in seeing it.

About the blow by. It's normal to have a pretty good amount of oil in your I/C and part of the intake tract. I however had waaaaaay more then normal. I even had some in my air filter box! I mean it was an extreme amount of oil.

Something for people to know too, if you're worried about your rings or piston ect.. I noticed with mine that if I unhooked any of my PCV lines while the car was running I actually had exhaust coming out of them because of the positive crank case pressure. It's a pretty easy check. Oh and if you ever have exhaust coming from your dip stick while the motor is running that's a pretty good sign too.

[free5ty1e]

lol... thats a good way to check for it - sounds like yours was way worse than mine, mine was a combination of the normal blowby oil on a 220km engine and the turbo blowing some of its oil in as well. Rebuilding the turbo with the t-bird compressor wheel and housing fixed that. I like to have a high content of air in the intake, oil's no good for mixing with the fuel.

Phil- Thanks man! I totally hope that you and Vikash can come for a visit when it comes time to do the actual swap. That'd be sweet.

Oh, just completely leave me out, man. I see how it is!

Remember, I have a hankerin' for hitting some of those roads you showed me. Its not THAT far of a drive....

And oh yeah, I guess I could help out if there is work involved, too. Its just that I make such a great observer or manager

[legacy92ej22t]

You know you're more then welcome anytime William! That'd be sweet if you could come when we do the swap though. Vikash was talking about teaching us how to make some authentic Indian food too. Mmmm, mmm.

Like I said in the past about my local roads. The ones I showed you were really just the tip of a very large iceberg. You aint seen nothing yet, my friend!

[legacy92ej22t]

Well it's moving right along. I have the coolant drained, radiator fans removed, the radiator pulled, the coolant lines all unhooked, fuel lines unhooked (atcually cut, fuckers are about next to impossible to remove! ), power steering pump set to the side, A/C set to the side, throttle and cruise control cables set aside and the turbo removed. Pretty much I just need to unhook the clutch fork, unbolt the tranny and unbolt the motor mounts and I'm ready to pull it! Yay!

I'm also going to have to swap over my wiring harnes because the '91 was slightly different. I might also swap over a lot of the hoses and crap because the ones on my original motor are in much better shape.

[vrg3]

Cool, cool, cool!

You might want to stick a jack under the tranny before removing the motor, so the tranny doesn't tilt downwards.

Yeah, always cut the fuel lines and just buy a few feet of 5/16" fuel injection hose to replace 'em with.

[legacy92ej22t]

Oh ya, totally. I have to replace the tranny mount with the group N bad boy too, so I'll be doing that anyways.

I can't believe how hard the fuel lines are to remove. It's ridiculous! I tried for a while too because my existing lines were cherry and I didn't really want to cut them. Oh well, it's worth it to just cut 'em.

[vrg3]

Oh yeah, I forgot about the mount.

I feel a lot better about high-pressure fuel lines being hard to remove than I would about them being easy to remove.

[legacy92ej22t]

Haha, ya, that's true.

Well, I'm off to go do more work here in just a few minutes. Hehe

[doormat]

i have a similar situation with my ej22t. well, there isn't a lot of oil there's a thin coating on the inside if the intake manifold, but there's also a thin coating inside the turbo's inlet elbow. so therefore the only possible source of oil upstream the turbo is the P.C.V. system right?

So this means that my engine has excessive blow-by pressure causing oil to flow the wrong way like this picture?

http://img165.exs.cx/my.php?loc=img165&image=pcv5ns.jpg

or could it be that PCV valve is not working and there's no other place for the pressure to but into the intake upstream the turbo? on nasioc people have posted the same type of problem on their new WRX with only 10K on the engine. would the problem still exist if the pcv valve did work? and could a oil catch can be solution?

is it possible to check for blow-by and compression with the engine out of the car? like with an electric drill to crank it or something?

[legacy92ej22t]

A little oil in the intake tract is normal. I wouldn't even sweat it at all if I were you. The PCV system draws oily vapor up out of the block and valve covers and pipes it into the pre-compressor intake plumbing as well as the intake manifold via the PCV valve so it's normal.

If the oil bothers you then yes, I think the solution is a catch can.

On mine I always had oil in my intake tract and especially my TMIC even when the car was healthy.

When #4 let go, the amount of oil became absurd though because of the positive crank case pressure. Oil was actually pouring out of everything when I was taking things apart.
