February 9, 201313 yr 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?
February 9, 201313 yr Author code reader says the engine is turning 25 rpm..... tried unplugging the crank sensor, no change....
February 9, 201313 yr 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? Edited February 9, 201313 yr by Fairtax4me
February 9, 201313 yr Author didn't have the cam pulleys off... yep, used the correct marks. but we're double checking now
February 9, 201313 yr Author 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....
February 9, 201313 yr 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.
