mfg recommendation ia change at 105,000. anyone had breakage prior to that?
is up to 5,000 or 10,000 over very risky?

mfg recommendation ia change at 105,000. anyone had breakage prior to
that? is up to 5,000 or 10,000 over very risky?

The scheduled changes are somewhat conservative. Theoretically, another 5 or
10 K won't make much difference, but:
*The Fine Manual also has a specification for age (so many years). If you
are under that, your odds are pretty good. If you are over, don't put it
off.
*It is very easy to put it out of your mind. Don't let that happen if you
elect to stretch the interval. It's like putting off homework in school...
the deadline bears down harder, and you don't really know when the deadline
is on the belt until it's too late! Choose a time to do it (like when a tax
refund has arrived) and make it stick.

You didn't say whether you have a 2.2 or a 2.5 engine.

The danger is when you have a 2.5 engine because it's an interference
engine & you will trash the engine. If you have a 2.2 engine, at most
a broken timing belt will get you a major inconvenience & a tow truck,
but you will not destroy the engine if the timing belt breaks.

All 2.2s? When did the dohc become sohc? Was either interference?

According to www.subaru.com question I was told ALL 2.5L engines are
interference engines.

How about the 2.2 liter engines?

 

[frank]

it is a 2.5. i understand the dangers, that is why i wanted to know what
margin i could have.

 

[Edward Hayes]

I suspect that the engineered safety margin is ~100% or 200,000 miles.
However; number of belt accelerations, tempeture, oil, water or
grease contamination will lower the belt life considerably.
