Timing Belt

Hi everyone!

I was driving down the highway and snap goes my TB.
Bought new bearings, tensioner, belt.
Lined up marks on cams and crank.
Installed new parts.
Turn the key and no firing!

Gets fuel and fire.

Please let me know what a solution could be!!!

Thanks!

I see this is your first post, so welcome to the forum from Oregon! :biggrin:

Sorry to hear of your problem. The Subaru engine is an interference fit engine, so are you sure the engine wasn't destroyed when the timing belt broke? :confused:

I think you need to get a compression test. It's very possible/likely that the valves are bent.

yep has to have compression to fire. bent valve = no compression.

I just changed the belt on my 2001 a few days ago. no problems,but mine had not broken first.

good luck on getting it fixed and back on the road. soon.

This happened to my 98 Forester back in Dec. I sold the car to a mechanic who wanted to rebuild it for his wife. He pulled the top off and found the valves destroyed. He ended up buying a new engine for it.

That sucks big dude.

This is most likely a situation somewhere between expensive and death. It happened to my previous (non-Subaru) car, and it's what got me to buy my Forester about six months ahead of schedule. And just like Brad84, I sold the corpse to a mechanic at the shop I brought it to.

Do you have maintenance records? How long was it since timing belt change? Any chance the work was warranted?

There may be hope since the OP has a Phase II SOHC (MY00). They tend to fare a little better in a timing belt self-destruction scenario than the DOHC variant. It also happened to RallyNav with her '01 recently, and aside from the new timimg belt she had a few valves replaced and kept on trucking.

Newbie here, but I read in the wrench article that there's 25% chance of no damage when a timing belt breaks on a subaru.

So there's hope (25%) :)

I suppose you could check eBay for rebuilt heads, but most people would just remove it and take it to a local machine shop. I'd call around and ask.

I dunno guys.... I've seen interference engines loose timing belts and bend some valves but on all 4 cylinders to the point that no sign of combustion is detected? Did the T-belt break with engine at the red-line? How did you check to be sure you have fuel and fire?

^^ if it is a manual or the torque converter is in lock-up the rotating assembly of the engine will be turned by the drive line until the operator or the TCU disengage the driveline from the engine. If the engine is spinning at 3000RPM a 1/2 second delay in reaction time or the TCU will result in about 25 revolutions of the crank, more then enough to wipe out the valves.
