Stupidru Posted November 13, 2003 Share Posted November 13, 2003 On my ej22t can i remove timing covers without removing alt - ps - ac? I think timing belt is snapped, compression is very low. Quote Link to comment Share on other sites More sharing options...
legacy92ej22t Posted November 13, 2003 Share Posted November 13, 2003 hehe I've got dejavous.=) Hey Mang, how you doing? IIRC you don't need to remove the actual units but you do need to remove the belts and one of the tensioners. You'll have to take the radiator fans out too. Take off the crank pulley ect.. If you have a Haynes manual it walks you through it pretty good. If you don't have a Haynes manual I suggest getting one( they're cheap and handy). If you're going to go through the trouble of getting in there to do the belt I suggest replacing the front seals and water pump too and maybe even the oil pump. How's the rebuild coming? Did your heads check out ok? Quote Link to comment Share on other sites More sharing options...
Stupidru Posted November 13, 2003 Author Share Posted November 13, 2003 I didn't even start on it yet, I'm still deciding what I want to do. Quote Link to comment Share on other sites More sharing options...

I think timing belt is snapped, compression is very low. You can't check compression with broken timing belt, If the timing belt has slipped you may loose some compression because the valves are not opening and closing at the correct time. But if it is broken the engine will not run at all. All accessories can remain in place. To verify the timing belt condition and alignment, you can just remove both of the outer (left and right) belt covers to inspect, nothing else has to be removed to do this. Removing the center timing belt cover requires removal of the accesory belts, the AC belt tensioner, and the crank pulley. The radiator fans come off first to make room to work in. To pull the fans: remove the radiator overflow, loosen the 4 lower fan shroud bolts (I think newer models don't even have lower bolts), and remove the upper fan shroud bolts. I recommend the Haynes manual as well, it also details how to check camshaft/crankshaft alignment (to check timing belt slippage). If replacing the timing belt, I recommend a Subaru belt since the belt is marked to match the alignment indicators on the pulleys. Makes aligning the new belt super easy. I have not seen aftermarket belts with these alignment marks, perhaps they exist, I have just not seen one. Quote Link to comment Share on other sites More sharing options...
mattocs Posted November 14, 2003 Share Posted November 14, 2003 When the Subaru dealer did my timing belt 12,000 miles ago they broke my belt cover and glued it back on where it broke. Quote Link to comment Share on other sites More sharing options...

It is common for these covers to break. The nuts are built into the rear cover, and often the bolts rust in place. When removing the rusted bolts often the rear cover is broken, or breaking the front cover is necessary. The only way to prevent this is to remove the timing cover bolts when the car is new and coat the bolts with anti-seize compound. Repeat the application of anti-seize every three years and everytime the covers are removed and you will never have one of these bolts seize. No seized bolts = no broken covers! You should use anti-seize compound on virtually every bolt on the car, except where threadlock is called for. If bolts are old and rusted, use liquid wrench to free them before attempting with a wrench. Preferably apply liquid wrench the day before the repair to allow it to soak in.
