Hi all, Does anyone know if there is a difference between the crankshaft sprocket for a 00/01 EJ251 and a '97-98' EJ25D? I'm trying to diagnose some engine-performance issues and will be looking at my timing soon enough... I have a EJ 251 block mated with the heads from a EJ 25D. The crankshaft sprocket came from the 251, and the cams are for the 25D heads. I read on here that there may be differences between A/T and M/T sprockets of the same block, and I do not know which transmission this block was mated to. According to opposedforces.com, and an online subaru dealer parts page, the sprocket is the same between the 25D and SOHC blocks. Just wondering if anyone knows of a difference. Issues at hand include odd imbalance/vibrations between 1800 and 2500 rpm. Feels like there's a cylinder not firing. Smoke test, and leak-down test are in order, hopefully next weekend after finals. Take care, Greg -
Hi all, I'm still in the assembly stage of rebuilding my engine (2.5L DOHC), but I've come across a weird issue. The new timing belt kit that came with my reman'd block, I just broke into it the other day to start putting the new sprockets on. The first sprocket one I opened, I bolted it on loosely just to see how it looked and feel the bearing, and to my surprise it wiggles. I'm not joking, this brand new never used sprocket, the bearing wiggles like a worn out bearing, though it's still tight when you spin it like a fresh bearing should be. I don't know about you but I'm getting a red flag about this, does anyone have any ideas on whether or not to use it? Thanks in advance, David -
I was driving down the freeway the other day and lost power steering and battery light came on. Pulled over and saw the main belt had come off.. crankshaft pulley / harmonic balancer was wobbling all over the place. Got the car towed to my Grandpa's shop and took mostly everything apart. Does anyone have tips for removing this crankshaft sprocket? The woodruff key I believe broke in half and part of it is still on the crankshaft. We have tried almost everything in the book to get the crankshaft sprocket / gear off and it won't budge. This type of thing is a little bit out of my ballpark maintenance wise however I have a mechanic coming on Monday to check it out. If anyone has some tips on how we can get this sprocket off so we can check out the rest of the crank to make sure it's ok I would very much appreciate it. Thank you

Hey guys, I just pulled the engine and did the head gaskets on my EJ251 legacy wagon. As I was about to install my new timing belt, I realized that I am entirely unable to get the left side cam sprocket timing marks to line up! The repair manual and multiple internet resources show that the mark should be going pretty much straight up towards a notch in the rear timing cover. My cover happens to be chipped, but I can see where the notch used to be. For some reason, the cam sprocket just won't stay where it *should* be, the tension whips the cam far to either side of it (YES, my crank timing mark is lined up properly, all pistons are recessed, I didn't just destroy my valves). These are the closest places to the timing mark that the cam will rest. Timing hash on cam is indicated with red line. Timing mark on timing cover is indicated with a yellow line. What is going on here?? I have read on multiple articles AND the manual that there should be no tension on cam when it is at proper point, this isn't some weird Audi that I should need special clamps for. Thanks for the help!
