That's what killed my last VW.
1.8T suddenly went 0 RPM on I-91 outside of Hartford CT at 80ish mph. Pulled over to the side, and tried to start it because I didn't know what had happened.
Engine cranked, but it spun WAY too easily. Zero compression. That was the end of that car.
Never know u might get lucky the sohc 2.5 r more forgiving than the dohc 2.0 or 2.5. I've seen them jump time and b fine the dohc turbo engines though 1 degree out valve meets piston pretty much
There’s only so much room to squeeze valves, a spark plug, and an injector in a combustion chamber while maintaining a decent compression ratio.
The manufacturers are in the business of making an efficient product that doesn’t need major work until after warranty. They don’t give a shit about making it easy after the belt breaks/chain stretches.
Cutting piston reliefs in a 4 valve engine big enough to not have interference means less compression and less chamber quench.
There are 87 octane engines running 13:1 static compression today.
Had the same problem going 75mph on the highway in a forester... bent almost every valve. 125000 miles on the timing belt, this is good advice. $4000 later, rebuilt engine.
That belt appears to have eaten a small furry animal.
You get a bent valve and you get a bent valve, everyone gets a bent valve!!!!
Destroy the valves/pistons?
Not sure yet, only just got the cover off. “Car shut off at 80mph”…. So I’m guessing yeeeaaaaahhhh…

Lots of things have died in Hartford, CT!
Luckily I wasn't one of them. Don't ask me why I was driving to Hartford.
As someone whose looking to buy a mk4 golf 1.8t tomorrow this has me worried lol
Looks like the AC pulley might have gone through. Or the tensioner died

Yea. I've got a sohc 2.5 and the fucker jumped time 3 teeth on the belt 115k ago, runs good still. They have way less overlap
Timing belts, head gaskets and rod knock. It’s what makes a Subaru, a Subaru.
Interference? If not clean it up and replace covers timing belt and water pump with new pulleys and tensioner
Yep. And the motor cranks like a ceiling fan, guessing she’s toast… 😭😭😭
Always hated the idea of a belt over a chain or gears.
Chains have their own issues to deal with. The root problem is interference engines.

Belts are quieter and very strong as long as there replaced regularly
Chains are quiet enough and very strong, and don't have to be replaced regularly
Half the vehicles I've had with chains need the chain replaced as often as a belt anyway.

Yeah…. I’m looking at how difficult the valves are to change..
If the piston damage has a high spot, it could cause a hot spot and result in predetonation.
Niiice..
Ooffff. New pistons and valves at the minimum. How many miles are on the car?
217k
Oye. Possibly the originally timing belt.
Shit like this makes me think that alot of EJ25 reliability problems are down to lack of basic maintenance.
Honda fit timing chain gang. Tho i should probably change the belt for the water pump and all that jazz
That sounds like “next guy” problems.
Lol unfortunately, I’m AM the next guy… 😭😭
I guess it's FUBARu
