Zues Marine Posted April 26, 2013 Share Posted April 26, 2013 finished up my 5mt/2.5L swap today and started it up HGs were replaced within 20k ago and motor ran 100% fine when i pulled it ... its running now but it runs horribly. new plugs, new wires, new oil filter, oil, gear oil the car will start after a couple cranks and then the idle will bounce between 700-1200 and randomly shoot up into the 2.5-3k range and hang there for a couple seconds theres white smoke billowing out of the exhaust, the temp gauge inside isnt working, the EGR seems to start smoking it stalls out and dies whenever i attempt to move forward or reverse and there is no CEL, the light is not burned out either ??

johnegg Posted April 26, 2013 Share Posted April 26, 2013 did you remove the intake manifold from the engine during the swap? did you plug the temp sensor back in, they are under the intake. double check ALL of the wire and hose connections. you left something undone. check the pins in the 3 connectors on the rear of the engine, passenger side. sometimes the pins get messed up. check all of the vac lines.

Zues Marine Posted April 26, 2013 Author Share Posted April 26, 2013 yes i did remove the intake and swapped harness' to the 2.2L one Link to comment Share on other sites More sharing options...
monkeyposeur Posted April 26, 2013 Share Posted April 26, 2013 And the timing is good? MAF is plugged in? Link to comment Share on other sites More sharing options...
Zues Marine Posted April 26, 2013 Author Share Posted April 26, 2013 yeah, everything ran great when i pulled the motor Link to comment Share on other sites More sharing options...
pleaidestar Posted April 26, 2013 Share Posted April 26, 2013 Do you have coolant lines on your throttle body is sounds like some is passing it. Link to comment Share on other sites More sharing options...
johnegg Posted April 26, 2013 Share Posted April 26, 2013 you need to double check the temp sensors and make sure thay are plugged in. they connect to the sensors which are on the coolant cross over pipe. the single wire goes the temp gauge and the 2 wire goes to the ECU. it seem prett sure the temp gauge is not plugged in and if the ECTS is not plugged in you could have a hard time starting it. and maybe a funny idle ,but i'm not sure about that. the white smoke may just be burn off. does it smell sweet? look for open vac lines, especially the large one that connects the plastic intake plenum to the IAC. MAF plugged in? Link to comment Share on other sites More sharing options...
Zues Marine Posted April 26, 2013 Author Share Posted April 26, 2013 so the sensors are plugged in tight and the MAF is good, i may have the hoses connected into the intake tube wrong but im not sure, there's also a very small hose coming off the IM pass side that looks like it goes to the ac pressure switch or whatever else is over there, i didnt know what to do with that i thought the smoke could be just oil i dripped onto the exhaust but its just constant out the tailpipe too long for it to be burnoff imo also worth mentioning that when i barely bumped the pedal rpms shot up to about 3k for a sec Link to comment Share on other sites More sharing options...
Zues Marine Posted April 27, 2013 Author Share Posted April 27, 2013 so the ONLY code im throwing is a P0115 and still shooting white out the pipe Link to comment Share on other sites More sharing options...
spooln30 Posted April 27, 2013 Share Posted April 27, 2013 White smoke= coolant burning Blue smoke= oil burning Black smoke=running rich So if your saying it's white smoke your getting coolant into the cylinders somehow. If you remove the intake hose and look into the intake manifold through the throttle body can you notice it being wet like from coolant? I'm wondering if you crossed a hose or maybe the TB cracked allowing coolant to enter the intake. It's impossible to blow your headgaskets while the cars not even running.

spooln30 Posted April 27, 2013 Share Posted April 27, 2013 Oh yeah when you removed the engine did you by chance get coolant down the exhaust header? I've done this on a couple of cars when doing headgaskets and it does take a while to burn off the coolant in the exhaust system. Link to comment Share on other sites More sharing options...
Zues Marine Posted April 28, 2013 Author Share Posted April 28, 2013 its possible but unlikely, i know it's definitely burning off the gear oil the AT drained all over the cats and my driveway, but its off the exterior my EGR is also smoking at the gasket pretty noticeably i dont know what hoses i may have crossed up whether intake or heater hoses..i dont have a/c hooked up but i feel like the smoke, the crazy rough idle and the "P0115 Engine Coolant Temperature Circuit Malfunction" all tie together Link to comment Share on other sites More sharing options...
Zues Marine Posted April 29, 2013 Author Share Posted April 29, 2013 so....this is still happening Link to comment Share on other sites More sharing options...
pleaidestar Posted April 29, 2013 Share Posted April 29, 2013 What a b****, did you by chance take the crossover pipe off? I think there are some o-rings in there that maybe compromised and letting coolant in the block that way...a shot in the dark maybe? If you have steady white smoke there has to be a steady stream of coolant entering the block, I'm still thinking throttlebody water jacket or gasket could be letting coolant pass.

Zues Marine Posted May 1, 2013 Author Share Posted May 1, 2013 nah, didnt take the crossover pipe off, i took the IM off, complete, so i could get to the harness and swap it out i'm going to take off the IM again today and check it out under there Link to comment Share on other sites More sharing options...
Zues Marine Posted May 2, 2013 Author Share Posted May 2, 2013 so i started it up and it took it around the block, my cats and the resonator were glowing red hot and smoking like crazy... wtf no CEL and the temp gauge went to the middle, no higher, rough idle.. but glowing cats... really? why? http://youtu.be/kiqlhQ1JqpU - even got some 1080p HD for you there is a missing header bolt causing the nice exhaust leak noise you hear, on some starts theres a nasty grinding noise til i let off the clutch... an intermittent low hollow knock sound.. sounds like its popping air out the intake filter sort of... you can hear it for the first time at :36 when the motor bogs downenough could it be the fuel thats been sitting in the car for the last 6 months? or could a clogged cat be the reason my last motor blew up Link to comment Share on other sites More sharing options...

johnegg Posted May 2, 2013 Share Posted May 2, 2013 the red hot cats sounds like unburned fuel . check the timing. if one side is injecting too late ...... did you remove the injectors or wiring from the intake manifold. ? did you get the injector wiring reversed? swap the connectors from driver side to passenger side.i have not done this but i know it has been done by mistake in the past.

pleaidestar Posted May 2, 2013 Share Posted May 2, 2013 Had heard about cats betting superheated like that, a friend of mine was working on his suzuki and his upstream cat did that and it ended up being the the valves in one cylinder got beaten up by the ground strap from a spark plug...that piece of spark plug ended up making its way into the cat and loosened all the catalyst up and clogged the rest of the exhaust system to the point that all the piping from the upstream cat back was glowing and barely running... None of that really explains the coolant entering your block but maybe (definately) your cats are clogged that bad...all of that sounds like a nightmare zues hope you get it going bud.

johnegg Posted May 2, 2013 Share Posted May 2, 2013 maybe the white smoke is from unburned fuel in the cats, not coolant in the combustion chamber. does it smell sweet? Link to comment Share on other sites More sharing options...
Sludgeroo Posted May 2, 2013 Share Posted May 2, 2013 His exhaust sounds to free flowing and smooth (from what I have seen) to be clogged, but who knows. Anything is possible. Link to comment Share on other sites More sharing options...
Zues Marine Posted May 2, 2013 Author Share Posted May 2, 2013 yeah, im pretty sure its not coolant that was smoking. its the cats and the resonator just after them, the injector wiring was pretty easy to differentiate just because the driver's side plug harness' are much longer and farther away than the pass side's but i mayyyy have gotten them switched up on their respective sides but i dont think i did, as it seemed pretty straightforward to hook it back up i did take and use the coil from the ej22, they're both diamond coils of the same PN, may try to swap them out, also had to buy a set of wires that i was wary of from o'reilly auto, maybe the injectors are plugged from the old gas? its got to be something i did since the car ran fine before i pulled the motor Link to comment Share on other sites More sharing options...
Zues Marine Posted May 2, 2013 Author Share Posted May 2, 2013 it seems like plugged up cats but would that cause the idle to go crazy like that video? Link to comment Share on other sites More sharing options...
Sludgeroo Posted May 2, 2013 Share Posted May 2, 2013 If the cats clogged maybe the 2nd O2 sensor is getting fluxuating readings and is making the engine ramp up and down like that to try and self correct why the 02 sensor is not getting a consistent reading. That is the final check and balance of engine management. Link to comment Share on other sites More sharing options...
johnegg Posted May 2, 2013 Share Posted May 2, 2013 maybe the 2nd O2 sensor ...That is the final check and balance of engine management. it is the final check, but not the balance. the rear o2 does not control or affect the operation of the engine in any awy. it just reports if the cat is doing it's job or not.
