Car - Connecting rod - what?

  • We are currently upgrading MFK. thanks! -neo
prolly caused by not being oiled properly. a number of other things can cause it though but most reasons are caused by ignoring regular maintenance.

looks like you moms car is getting a brand new engine
 
I would ask to see the remains of the motor, if it ends up not being covered under warranty it WILL be expensive. Believe it or not, some service departments have been known to be full of BS.
 
What to do if they give me problems about the warranty? It's supposed to have a 100K mile warranty - it has only about 65K miles. Is it possible that they will say it was our fault for whatever reason? If so, what should my next step be?
It's a 2002 9-3 2.0 high output turbo engine, for those that know engines, this might help answer any more questions.

Any of you work with engine manufacturers, etc?
 
Hmm, turbo? I know gas prices are going up, but on cars with turbos NEED to run higher octane fuel,specifically because a turbo adds more pressure than atmospheric pressure alone. This pressure changes the harder you romp the gas pedal. knocking or auto ignition is when low octane fuel combusts from the heat of being compressed. As you add more air with a turbo, there will be higher temps in the cylinders than under no boost conditions. the higher the octane, the less likely it is to knock- when the fuel combusts before the spark plug fires. detonation can ruin engines very quickly, because when a cylinder auto-ignites it is working against the other cylinders and putting an immense strain on the engines parts.
It is wise to run minimum 92 octane on any car with high compression, so you can take advantage of advanced spark plug timing to really let the engines performance shine. On motors with aluminum cylinder heads its not as important, cause aluminum dissipates heat alot better, making it less prone to auto-ignition/knocking. It is rare to find a modern car with high compression and Iron heads, But on such a vehicle you MUST run 92+ octane, as Iron heads do not disipate heat well, along with high compression (10.0 to 1 or higher) you run the risk of knocking.
Idk, i cant diagnose your mothers car online without seeing it, but hopefully this is some insight.

That's probably the 2.0 LSJ just like my car except with turbo instead of supercharger. The computer will retard the timing if you use low octane gas. I use the high octane to be on the safe side and get the most out of the engine. The motor should be covered, if they determine it wasn't user error.

The computer only retards timing when the knock sensor in the block goes off. it has no way of telling what octane fuel is in the tank.
The warranty should either be 3 yr or 5 year, or 100,000 miles, whatever comes first. Technicians can and will try and deceive you, dealerships do not want to replace an engine under warranty, its too expensive on their part-
play hardball with them.
If they do repair it, Demand a loaner car. they have to have the engine shipped, and then the lazy techs are gonna smoke 2 packs of Cigs before the new engine is in the car.

Depending on how old that Saab is, you would have to try REALLY hard to brake those rods. The rods are specially reinforced on the newer 2.0 LSJ motor

No no.. the rods are strong! the block is weak.. :(



Sorry to hear it happened. Hope it falls under warranty because anything recently newer demands a high price at salvage yards. I'm highly doubting it's a low grade fuel issue unless Jude's mom has one aftermarket hopped up Saab. Even if it was IMO it should fall under warranty.
 
This is just a straight up dealer-purchased car - nothing done to it. Hopefully tomorrow I'll get an email saying "Yeah, the warranty covers it." If not - .................

Thanks for the ideas and advice guys - will keep you guys posted.

Very true.

On another note, my friend had 2 of his rods shoot through his block, making 3 holes. Was quite a sight.
