badbillymac Posted January 31, 2016 Share Posted January 31, 2016 I have a 2009 forrester x and last night Im driving at 65mph and engine light comes on and then car stalls. I look and there is a hole in the block 1.25 inch wide by 3 inch long near the crank with smoke rolling out of it. any idea why this failed? I have had all the required oil changes and such since I owned it. ???? Bad billy Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted January 31, 2016 Share Posted January 31, 2016 How many miles on it? How long have you owned it? How often does the oil get changed? Do you check the oil level on a weekly basis? Did you check the current oil level? Quote Link to comment Share on other sites More sharing options...
Numbchux Posted January 31, 2016 Share Posted January 31, 2016 Rod bearing spun and seized. Rod broke in half, and the half still attached to the crank punched through the block. Also called "Throwing a Rod" Typically it's caused by a lack of oil to that bearing, this can be caused by several things, be it a clog somewhere limiting flow to only that bearing, or that part of the engine. Or something causing low oil pressure to the whole engine (cracked pick-up tube, oil pump problem, etc.). It can also be caused by high rpm use, or turbo cars that have had the boost turned up (I assume neither of these apply to you....). It can also be caused by detonation/misfires (causing contact between the bearing and crank), which can be caused by either fueling or ignition. IMO, none of these things are any more likely on your car than most others (Subaru and others). Long story short, it'll be very difficult to tell. It might be due to some neglect or abuse, but it might just be a fluke. Quote Link to comment Share on other sites More sharing options...
lmdew Posted January 31, 2016 Share Posted January 31, 2016 (edited) If you want to sell it let me know. I'm in Colorado Springs and work on Subaru's for fun. Thanks Larry I have an 05 OBS with a rebuilt engine that's ready to go. Edited January 31, 2016 by lmdew Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted January 31, 2016 Share Posted January 31, 2016 hmmm, - .. there is a hole in the block 1.25 inch wide by 3 inch long near the crank just wondering if this could be a hole melted thru the plastic timing cover? Quote Link to comment Share on other sites More sharing options...

1 Lucky Texan Posted January 31, 2016 Share Posted January 31, 2016 can you post a pic of where the hole is? you probably need the eyes of a mechanic on this issue. Guys typing on the internet are only making guesses without more details. Quote Link to comment Share on other sites More sharing options...
Numbchux Posted February 1, 2016 Share Posted February 1, 2016 Anyone???? Yes. I spent quite some time last night considering and typing up a thorough response, despite having very little information to go from. 1 Quote Link to comment Share on other sites More sharing options...
DaveT Posted February 1, 2016 Share Posted February 1, 2016 Pictures would help. Quote Link to comment Share on other sites More sharing options...
CNY_Dave Posted February 1, 2016 Share Posted February 1, 2016 Could be a snapped timing belt if that hole is indeed in the front. Quote Link to comment Share on other sites More sharing options...
ccrinc Posted February 2, 2016 Share Posted February 2, 2016 Hole in the block = thrown rod. Period. "Why" can be complicated, but it's usually oil related. Bad PCV valve. Low oil, lack of changes, wrong oil are the usual culprits. It's possible that the circlip for a wrist pin on a piston broke. All kinds of things are possible, but the fact remains that you now need a new engine. You will also now have metal all through the rest of the engine AND (NOTE!) all through your intake manifold as well. Be sure the manifold is professionally and thoroughly purged before putting it back on or it will ruin the next engine as well. Several people have given you info: what you do with it is your choice.

CNY_Dave Posted February 2, 2016 Share Posted February 2, 2016 Another one of those where we never get to see the season finale? Was it the timing cover? Was it the block? Will Stimpy be able to resist pressing the shiny red candy-like button? 2 Quote Link to comment Share on other sites More sharing options...
