What does this look like?

so....you know what's happening here? Possibilities?

Looks like oil!


Maybe its your valve cover gasket.

 

Looks bad.

 

Remeber the post where I said it was mis-firing.... that was in cylinder #2..... now it was misfiring just for this happened. Then the engine died on me, and we found oil coming out of the spark plugs.

Russ.... possibilities?

 

OIL OUT OF THE SPARK PLUGS!!!!! what were you doing? poor subi engine. (time for the ej20 swap)

 

It'll start up, idle for few seconds then choke and die. But I'll do a compression test and what's needed

 

I have a compression tester if you want to use it. You basically replace one spark plug at a time with the compression tester to find out how much compression each cylinder has. If one is severely lower than the others, you're screwed. You're also screwed if they are all below spec.

 

Matt, I'll be looking forward to using your com. tester.
This mis-firing occured only at high rpm with load in 3rd gear. maybe this is when the crank case is putting lots more oil pressure thus a weak seal at the valve cover gasket breaking?

My car is still not with me and I'll be checking it out were I parked it last night. Would OIL come out if I took off the valve conver? I know I took one off before on my mom's Leggy but I don't remembered if we drained the oil before doing so...

Well, first of all. I think you drive that poor little car a little too hard. [xx(]
I have heard that if you put in wrong sized plugs, that can lead to a leak and/or wear down the threads. Thus, the oily substance coming out there. With an older engine you can have blow-by from the cylinder walls being worn. Ford F-150's have had problems with the wrong sized plugs installed at teh factory and them BLOWING OUT! Smell that stuff and see what it smells like.

EDIT: Yes oil will drain out when you take off the valve covers as far as I know.

 

in a way, I do drive the car a bit hard....hahah! "a bit[/bit] hard"

I guess I'll be getting those copper NGK plugs.., What's the pricing on those? Could I get them at Fleet Farm? Where?

We got her towed home tonight and she's sitting where she left 24hrs before. lol My brother aggreed that the crank case is putting lots more oil pressure thus a weak seal at the valve cover gasket breaking or what not. It's NOT blowing out burnt oil from the back at all.

We'll see tomorrow. BTW, the car is in FWD mode. I'll be building up my 5spd AWD tranny with RA gears and 4.444 final drive with NEW syncros. I'll be searching for that dial guage and shimming specifications.

 

ide also say it may be a valve cover gasket, i say spring for the denso iridium plugs though, just because! also is your car smoking at all? that would mean oil in the cylinder, or coolent!...you never know, it is the newer style 2.2, the one that is externally identical to a 2.5!

What's going on w/your rear diff right now? Todd was saying something about it being bad to use FWD because of the front and rear wheels turning at different speeds. Although, he may have been referring to dyno testing only. hmmm... Honestly, I think the standard NGK plugs would work fine on your car.

 

Start right where you see the leak coming from. Pull out that spark plug wire. Put a socket on your spark plug and feel if its loose. Hopefully it's that simple. If it's tight then pull the plug and look at the electrode and threads near the tip. Note its condition and report back :mrgreen:

If you want you could come over and we'll look at it. Then you can pick up those cylinder heads also

You will NOT leak out ALL your oil from pulling the valve cover. You will drip some thats cought up in there but the majority of it drains down into the pan. You should not have to drain your oil pan. Throw down some cardboard below the engine, pull it off, and you will have minimal mess.

Later

hahaha I have a 5spd FWD Leggy tranny in my car right now.

Matt, I aggree that it is possibly the O-ring around the plug galley. Too much oil pressure from hig RPMs causing it to break or what not. Too much heat probably making it hard and probably cracking afterwards.

 

You should have properly warmed up your engine before performing any of your stunts. (You know what I'm talking about, Mr. MPH limiter)

 

Well....what I found out that the spark plugs are just fine, needed a little regapping but they're not wet from oil I don't think, more like fuel.

I'm going to do a Compression test. Gonna borrow from my auto tech teacher. If it has bad pistons or something...I'll be saving up for the STi shortblock.

What's the compression that I should be looking for?? I'll be looking at the ALL DATA at my auto tech teachers desk but post away if you know it. It MIGHT be my heads too, who knows...

EDIT: Could I take out the heads with the engine still on the car? Unbolt engine mounts and tilt engine with floor jack.... Probably have to do a leak test with Keroscene

 

Good idea with the compression and leak down tests. Could call a stealership up and ask service dept. to look in the FSM for compression numbers.

Heads should come off in engine bay easily. All the EJ22 heads I've pulled were with the engine in the car. I think they are way easier to do than my EA82 heads. EJ heads you can pull with the valve covers on!

 

If you want an Sti EJ25 shortblock, you got less than a week to buy this one for cheap. http://cgi.ebay.com/ebaymotors/ws/e...tem=7951827536&category=33613&sspagename=WDVW

<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">

I beg to differ! You have to pull the cams out to get to the head studs. Please check your information!

Okay, every EJ22 and EJ18 I've pulled heads on I didnt have to touch the valve covers....

better?

 

you've pulled the older ones, the newer ones look identical to a 2.5

Still dont believe it. So all the head studs are external on those? The only external studs I can think of in all the motors I have done are v-twin motorcycles. Interesting
<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">

Well belive it cuz I'm not just making stuff up here. I've physicly pulled these heads with my two bare hands. Two of the heads are on my shelf in my garage right now; valve train fully assembled and untouched when I removed the heads. They werent studs either; really long head bolts.

AWDimprezaL: correct; these are first gen EJ I'm talk'n about here.

I have never done any work on phase 1 motors just phase 2 that is interesting stuff. So they would have to be SOHC with rockers then correct?
<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">

Correct, SOHC. I haven't pulled heads on an DOHC EJ before. Only seen one in person really Looked BIG

 

I've seen Morgan's EJ22 heads in his garage. They were assembled. :?:

 

phaze one power!

 

Okies, so here's the deal. Spark plugs and wires and coilpack all work. Crank sensor and cam sensor all work. Injectors all work because it starts everytime I crank it.

Every crank it'll start up and come to idle. It'll idle for a bit and then choke and die. Seems like something it blocking it from breathing or something. It's getting fuel because it starts up every time.

Don't know if it really is the fuel pressure regulator...

 

Mass Airflow Sensor

Dont rely on some codes to save you. Do an OHMs resistance test on each pin of the MAF and check it against OEM specifications.

 

i would definatly say maf...i forgot to plug mine back in when i put my intake on....it idled for about 2 seconds then died

 

I'll clean the MAF and see what happens first. (Brake cleaner, and I won't touch because it's fragile)
I don't know how many OHMS it should read...

 

Cleaning the MAF didn't help...
mmm....

 

Whoa, are we talking about MY99 MAF sensors? I've got a few of those sitting around, one new in the box. Dunno if it's the same one for non-2.5 engines though.

 

Yes, we're talking about the MY99 MAF sensors. IF you're willing to come give me a call Garret. e-mailed you...

 

Are there ANY electrical solenoids anyone can think of besides the fuses?

 

On the opposite thought pattern, could it be running too rich? I know it's fuel injected but who knows?

 

its definatly rich, i smelled it when he fired it up...STINKY! but still a badass wagon nonetheless

 

Erick...any updates? We're all waiting on the MAF. Ireally hope it is the maf.....other than that....I'm really clueless because of all the things we've checked already....

If you think something should be checked, then do point it out so I can take a look.

 

nope, the master tech is on vacation! ide say if the MAF doesnt work then get it brought to the shop[xx(] wish i could be more help
