Numbchux Posted February 9, 2013 Share Posted February 9, 2013 99 Outback SUS that I've posted about before. Bought it a couple weeks ago. Crank pulley had backed out, lots of oil everywhere. But it ran. Pulled it out, did a mild reseal (pulled the valve covers off to find the heads have been recently hot tanked, so we didn't do head gaskets). The crank snout was so screwed up, we ruined the tone ring on the sprocket getting it off. A friend had a brand new one he bought for a 01 RS, so we used that. We just put everything together, and went to start it up, and it cranks a few times, catches, then backfires through the intake, puff of exhaust out of the airbox and everything. I'm 99.9% sure we got the timing right with the new belt. Everything appears to be hooked up. Any ideas? is there a chance that the tone ring on this sprocket is slightly different?

Numbchux Posted February 9, 2013 Author Share Posted February 9, 2013 code reader says the engine is turning 25 rpm..... tried unplugging the crank sensor, no change.... Link to comment Share on other sites More sharing options...
Fairtax4me Posted February 9, 2013 Share Posted February 9, 2013 (edited) There are only two types of crank sprockets. One has 6 reluctor teeth, the other has like 30. You used the dot on the back of the sprocket for timing right? Not the arrow on the front. Cams could be out as well. Are you sure you put the sprockets back on the correct cams?

MilesFox Posted February 9, 2013 Share Posted February 9, 2013 COuld the spark plug wires be backwards? Link to comment Share on other sites More sharing options...
Numbchux Posted February 9, 2013 Author Share Posted February 9, 2013 COuld the spark plug wires be backwards? We checked that... It was the timing belt. Must have lined up without the slack taken up or something. All 4 cams in sync with each other, one tooth off at the crank sprocket. After a little shenanigans to get the coolant system bled....it runs great. Was supposed to be a fix n flip.....might keep it.... Link to comment Share on other sites More sharing options...
MilesFox Posted February 9, 2013 Share Posted February 9, 2013 Yeah, go for it. It always seems the one you sold is the one you should have kept. Good luck with the rest of it. Link to comment Share on other sites More sharing options...
