Drakien Posted January 8, 2009 Share Posted January 8, 2009 What does white smoke out of the intake mean? I know it definitly isn't good. I just finished swapping in an EJ25D motor into where one used to be. Timing is perfectly on. I drained the oil to check for coolant. Not a drop. What is the problem?

Drakien Posted January 8, 2009 Author Share Posted January 8, 2009 The car doesn't start, it smokes while trying to turn it over. Link to comment Share on other sites More sharing options...
Skip Posted January 8, 2009 Share Posted January 8, 2009 Here in the states we do not see an EJ25D Could you explain what it is? Is there any chance that the exhaust is plugged up causing massive back pressure? Intake valve bent due to timing belt breaking. Fixed the belt but didn't check for valve damage? Can you do a compression test? Link to comment Share on other sites More sharing options...
nipper Posted January 8, 2009 Share Posted January 8, 2009 How many miles on this engine? When was the timing belt done? Are you electing a pope? (hehehehe) nipper Link to comment Share on other sites More sharing options...
Drakien Posted January 8, 2009 Author Share Posted January 8, 2009 (edited) The motor is from a 97' Legacy GT. The exhaust is not clogged. I have not had a chance to run a compression check yet. I will run a compression check in the morning. As for the bent valves, its a possibility. I got the motor and it already had a new timing belt on it, However I bought a new one and installed it. 140k miles on the motor. Edited January 8, 2009 by Drakien added mileage Link to comment Share on other sites More sharing options...
nipper Posted January 8, 2009 Share Posted January 8, 2009 double check your timing. Many a soul have come on here that were "100% sure" they had the timing right only to have it wrong. www.endwrench.com will help They dont have the turbo engines listed there, but they have the 2.2 timing which should be similar. If the engine ran before you did this I'm betting the timing is off. If it did not I'm betting on bent valves. nipper Link to comment Share on other sites More sharing options...
Drakien Posted January 8, 2009 Author Share Posted January 8, 2009 I actually had a mechanic come over and help the second time, because I thought the timing was off when I first replaced the belt. The engine supposedly ran when the guy before me took it out of his car for an STI 2.0 swap. Link to comment Share on other sites More sharing options...
nipper Posted January 8, 2009 Share Posted January 8, 2009 OK i misread that, i thought it was a 2.0T. Hold a peice of paper up to the exhuast pipe. Have someone crank the car engine. If the paper gets sucked to the tail pipe the engine timing is off, bigtime. nipper Link to comment Share on other sites More sharing options...
Drakien Posted January 8, 2009 Author Share Posted January 8, 2009 Alright I will do that before I break open the compression tool. If it is a bent valve, would I be able to just do a valve job on the one side with the bent valve or would I have to do all of them? Link to comment Share on other sites More sharing options...
nipper Posted January 8, 2009 Share Posted January 8, 2009 140,000 miles I would say a full valve job. Otherwise you may have an engine that doesnt run smoothly at idle, but I still think its out of time. nipper Link to comment Share on other sites More sharing options...
Drakien Posted January 8, 2009 Author Share Posted January 8, 2009 (edited) Alright I will run the "Paper test" and go from there. Thanks for your help Everything I have read says the smoke out the intake is a timing problem. Which is why I had a mechanic come do the timing for me. Is it possible the computer has a problem? Is there a computer timing? Edited January 8, 2009 by Drakien Link to comment Share on other sites More sharing options...

Somputer only controls the boom, mechanically the suck and squish are still gears and belts. Without those two you dont get the boom, hence the smoke. Even a burnt valve may cause a backfire, but not smoke through the intake. Link to comment Share on other sites More sharing options...
Drakien Posted January 9, 2009 Author Share Posted January 9, 2009 Interesting, So my friend held the paper about 2" from the tip, it blew out, then sucked in. So he put it right up against it. It blew out, then sucked in. Then I stopped cause I didn't want to mess up the engine anymore than it already is. I took a short video of the smoke coming out the intake, I will host it on youtube and post it up here after work. Link to comment Share on other sites More sharing options...
nipper Posted January 10, 2009 Share Posted January 10, 2009 SUbaru Cylinders are 1-3 2-4. Your timing belt has jumped, hence the pull push at the exhaust pipe. nipper Link to comment Share on other sites More sharing options...
Drakien Posted January 10, 2009 Author Share Posted January 10, 2009 Hmm, so I would have to try again on the timing? For the 3rd time lol Is there still a possibility that there is a bent valve? I have an extra set of heads from my old motor. But I dont want to tear down both engines unless I have to. Link to comment Share on other sites More sharing options...
nipper Posted January 10, 2009 Share Posted January 10, 2009 No bent valve. Sucking in of the air at the exhaust pipe is timing. Think about how an engine runs, it will make sense. If it was a bent valve it wouldnt do anything at the exhaust pipe. nipper Link to comment Share on other sites More sharing options...
Drakien Posted January 10, 2009 Author Share Posted January 10, 2009 Alright so I am somewhat lucky. I will go ahead and attempt the timing again. Thanks for the assurance and your help Link to comment Share on other sites More sharing options...

Drakien Posted January 10, 2009 Author Share Posted January 10, 2009 If it doesn't work for the 3rd time I would have you explain in detail, but until then I wont bother you to do it lol Link to comment Share on other sites More sharing options...

johnceggleston Posted January 10, 2009 Share Posted January 10, 2009 If it doesn't work for the 3rd time I would have you explain in detail, but until then I wont bother you to do it lol the errors usually made when replacing a timing belt are due to using the wrong marks on the cam sprockets and or the crank. if you have any questions at all, search/ read / and ask. maybe yours just slipped, when you were putting the belt on, but better to be sure than to have to do it again. good luck.
