So there has been alot of questions about bent valves from timing belt failures. It's been my experience that if the belt breaks, it surely bent valves. But sometimes, if the belt just skips a few teeth, things are okay. Example : this '06 forester started running incredibly rough about 10k miles after the owner did his own timing belt replacement. Pulled the covers, and found this IMG_2926 by Dans Subaru, on Flickr IMG_2925 by Dans Subaru, on Flickr He had striped out the lower idler hole, and it had walked funky out of the hole and forced the belt against the inside of the cover until it shredded and it had skipped 2 teeth on the passenger and 4 teeth on the drivers side. After tapping the lower hole deeper, and installing a longer bolt to hold the idler, I installed a new belt and did a compression test. 165+ in all cyls. Lucky SOB So if yer belt has skipped, don't go immediately tear the engine down. Worth a compression test first.- 4 replies
