November 25, 200619 yr Just a subtle reminder to those of you that say "Oh that idler feels fine." This engine had a timing belt break around ten kmi before this failure. The first belt breakage cost two bent valves in one head. The resulting train crash (valve train) from this failure cause both heads to suffer bent valves. The belt ran while skipping/stripping teeth long enough that both heads got into the action. The engine is an MY97 EJ25 with around 175 kmi. It is now being converted to a "hybrid" EJ 25/22.
November 25, 200619 yr Man that looks really bad! I will keep that in mind when I get a timing belt type sube.
November 25, 200619 yr Ouch, had the same thing happen on the wifes '93 Legacy "L" wagon. Drove it on the trailer, took it home and had it running one hour later. There were no bearings left at all when it started making so much noise she couldn't drive it any more. Sorry about the damage Skip. Good luck with the hybrid build though.
November 25, 200619 yr Thats why i recomend replacing parts under the "as long as i am here" theory as oppsed to "it looks ok" theory. Murphy's law nipper
November 26, 200619 yr Please, do share with us the information regarding mileage on those idlers !! He said 175k miles.
November 26, 200619 yr Ouch indeed! Generally, I replace all of the idlers and the tensioner assembly at the 120k interval regardless of condition. If there's any play or they look rusty, I'll change individual ones at 60k. If the customer is trying to save money, I'll do the same at 120k and then replace everything at 180k. There is just too much of a risk with running old idlers to be able to justify not spending the extra money to replace them.
November 27, 200619 yr Author First off, I thank for all the replies and would like to add the event was the final straw for the previous owners. They junked the car as a result. ( 97 Legacy OB 175 Kmi ) I dragged it kicking and screaming from the boneyard. Qman - wish I was as near as fast with wrenches as you are, this conversion is going to take a bit longer -- nah lets say a lot longer. Thanks for the support. As for now... If anyone has tips or tricks to this conversion please let me know. (i.e. I guess I use the new improved EJ25 head gaskets, water pump, idler pulleys, rear and main seals and ?) obviously the 2.2 timing belt and cam seals Like Nipper says "as long as I'm in there". Once again, I humbly say thanks for your condolences. I hope this helps someone avoid the same catastrophe.
November 27, 200619 yr Yep, use the EJ22 belt and EJ25 gaskets. You'll have to use the EJ22 intake manifold as well. If the heads are newer type, they'll have single exhaust ports and will need that exhaust manifold. Other than that and the EGR...you should be good to go. Keep your EJ25 engine harness and put 92octane in and all will be well with the world. Jay Storm
November 27, 200619 yr Author Setright, sorry I missed your question, as far as I know they are like Shak said as factory. Jay thanks for the input. I thought ( ?) I read somewhere that I could use the EJ25 intake? Are you sure it will not bolt/match to the EJ22 heads? I'd like to use it as I thought ( ?) it would have better flow characteristics. The EJ22 I'm using is in the car and running at this time but has a bad HG. It has the same exhaust ports / EGR and was a plug and play.
November 27, 200619 yr At least the belt didn't shred. I fixed a 91 turbo legacy that the idler gear busted. It destroyed the belt. http://www.main.experiencetherave.com:8080/subaru/images/shreddedtbelt/
