mtsmiths Posted September 7, 2006 Share Posted September 7, 2006 After reading the title I wondered WTF? But then I just watched "World's Fastest Indian". If you haven't seen it, do. Cracked ring? Quote Link to comment Share on other sites More sharing options...
subie94 Posted September 7, 2006 Author Share Posted September 7, 2006 Cracked ring? i hope not..hoping one or so might be stuck. anyone ever add a quart of trans fluid into oil,run for a bit then change oil? (that's what my mechanic mentioned doing and he has worked on soobs for some time now,like 15-20yrs) Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted September 8, 2006 Share Posted September 8, 2006 Is it burning/using anything such as oil? I've heard of the adding ATF to the oil as a 'flush'; I don't think I'd be up for it. Sometimes people pull the spark plugs and shoot some ATF or something like lube control lc20 down in there and let it soak for a few days cranking it over for a second once a day (not starting, as the plugs are out) or so to soak the junk off the rings then change the oil after a couple days and fire 'er up. I don't know how well that would work on a Sub since the pistons are essentially horizontal verses many engines that are more at a slant to allow the stuff to work into/soak through the rings. Some people pull water in through a vacuum line which supposedly does a really nice job of decoking the piston tops and stuff; i've never tried it. You could maybe do a cylinder leakdown test or compression test to see if you've got leaky rings or anything freaky like that..harbor freight has the cylinder leakdown test kit on sale for like $25 right now...

Manarius Posted September 8, 2006 Share Posted September 8, 2006 Looks like it's running a little too rich at start. Quote Link to comment Share on other sites More sharing options...
Legacy777 Posted September 8, 2006 Share Posted September 8, 2006 It's running rich, and it's burning oil. You've got internal engine issues. Either head related or bottom end related. Do a compression test and see what you come up with. If pressure is low in one cylinder, squirt oil into the cylinder, crank it over and do the test again. If the pressure goes up, you've more then likely have bottom end issues. If pressure doesn't go up, you likely have head issues. There is no "quick fix" Quote Link to comment Share on other sites More sharing options...
ericem Posted September 8, 2006 Share Posted September 8, 2006 Can a PCV valve cause this problem? Or a cheap air filter? Or maybe some seafoam odd to do the trick? Quote Link to comment Share on other sites More sharing options...
nipper Posted September 8, 2006 Share Posted September 8, 2006 PCV will cause this problem. And yes you need a tuneup and maybe an 02 sensor. nipper Quote Link to comment Share on other sites More sharing options...

tcspeer Posted September 8, 2006 Share Posted September 8, 2006 Smoking after starting engine is most likely valve stem seals leaking, at least that was what caused it in my chev. http://s24.photobucket.com/albums/c34/beretta92d/?action=view¤t=exhaustsmoke.flv wasn't able to rev to high due to neighboors,only got up to 3k (don't mind the beginning) anyone else's soob smoke this much?

subie94 Posted September 8, 2006 Author Share Posted September 8, 2006 So what exactly does this PCV valve do? Definition: The Positive Crankcase Ventilation valve is an emissions control device that routes unburned crankcase blowby gases back into the intake manifold where they can be reburned.

subie94 Posted September 8, 2006 Author Share Posted September 8, 2006 Smoking after starting engine is most likely valve stem seals leaking. that's the only time she smokes.almost like when engine's not running,oil is dripping into combustion chamber and collecting on top off piston.and when i start the engine,oil gets burnt(or something like that) vavle stem seals sound easier to replace then rings..

tcspeer Posted September 8, 2006 Share Posted September 8, 2006 On the Chev. engine they can be replaced without removing heads, I dont know about Subaru. It seems like it would be harder for oil to leak from the seals on the Subaru being the head is on the side. that's the only time she smokes.almost like when engine's not running,oil is dripping into combustion chamber and collecting on top off piston.and when i start the engine,oil gets burnt(or something like that) vavle stem seals sound easier to replace then rings..

porcupine73 Posted September 8, 2006 Share Posted September 8, 2006 pcv=positive crankcase ventilation. It's basically a check valve. It passes combustion blowby gases back into the intake air stream. Some people like to put a catch can inline after the pcv valve to catch oil and maybe settle oil vapor/mist and other stuff so it doesn't get fed back into the intake thus potentially gumming things up.

johnceggleston Posted September 8, 2006 Share Posted September 8, 2006 my 61 chevy pick up had positive crankcase ventilation ... it was a tube hanging off the side of the block venting the crankcase. it was positively ventilating and driping with oil. pcv=positive crankcase ventilation. It's basically a check valve. It passes combustion blowby gases back into the intake air stream.

cookie Posted September 8, 2006 Share Posted September 8, 2006 I agree there is no quick fix if the PCV is ok. Sometimes switching to synthetic oil can cut smoke for a while, but is not a real fix. I understand it just smokes less. Quote Link to comment Share on other sites More sharing options...
mtsmiths Posted September 8, 2006 Share Posted September 8, 2006 So what exactly does this PCV valve do? The PCV valve takes the 'blow-by' combustion gasses from the crankcase (they usted to just vent into the atmosphere via a down tube) and routes them into the intake manifold where they are burned. Kinda like a SCUBA rebreather. I dunno if a clogged PCV would create excess smoking or not, but they're cheap, as are air filters, so whynot. Back in the 'old days' (i'm talking O-L-D here), I cured many an engine of this by mixing a couple heaping tablespoons of BonAmi into 20WT oil and running it through the carb. The Bon Ami would deglaze the cylinder walls of varnish and burned oil build-ups and reseat the rings. But this was on very low compression cast-iron block engines ... do NOT try it with a Subaru. Try Seafoam Quote Link to comment Share on other sites More sharing options...
cookie Posted September 8, 2006 Share Posted September 8, 2006 My understanding is that they cause oil bunring when they stick open or the spring gets weak and it opens too soon. This is supposed to suck oil from the crankcase into the manifold on decelleration. On the ones with no spring sometimes the ball and seat gets worn and causes the same thing.

subie94 Posted September 9, 2006 Author Share Posted September 9, 2006 is there a chance that running upper engine cleaner could cause probs with pvc? it wasn't recent but i put in a new pvc awhile back. i'm picking up a new one anyway tomorrow along with new plugs and air filter...gonna have to wait for wires until next payday. and as far as i remember,she has blown smoke every time i'd rev up the engine at least ever since i've owned her(3yrs). here's the stock vid. http://s24.photobucket.com/albums/c34/beretta92d/?action=view¤t=stockexhaust.flv Quote Link to comment Share on other sites More sharing options...
subie94 Posted September 9, 2006 Author Share Posted September 9, 2006 well here's an update on my oil burning ej22... well after picking up the plugs/air filter and pvc and proceeding to leave the parking lot.i noticed the engine wasn't running right..sputtering and what not.well i got her home and proceeded to change the plugs.1st one out was good(normal wear) well the next one out would explain the sputtering and feel of running on 3 cylinders..it was covered with oil an sludge.. apparently my valve stem oil seals need replaceing (so said my soob mech friend) and of course the news he told me didn't make me any happier...on how the engine has to come out in order to do the head work. :banghead: i guess that would explain were my oil is going :-\ oh ya an i could only replace 3 plugs cause the 4th has a heli coil on it and i was sure if it would be a good idea to try and swith the heli over to new plug...
