Maybe too soon to tell, but I think my '03 SS might be a goner. Today it developed a severe knock on my way to work. It ran for about 20 minutes while I was trying to nurse it home before it shut itself off. Oil pressure was good, oil looks free of coolant or metal flakes, temp stayed in the normal range the entire time. I thought I'd make it back home actually. I didn't. Had to wait an hour plus for a tow home - about 50 miles. Only ~73k on that '04 L67 too. I'm waiting for the diagnosis from the shop that last worked on it a couple of weeks ago as to what happened. I have some ideas.

 

That Suck's , My 2005 Monte SS L67 spun a cam shaft bearing at 16,900 miles GM installed a new engine for FREE..

 

Sad to hear about that, poor l67 always a disappointing thing when something major like this goes wrong with a car.

 

That's no good!

 

Sorry to hear that keep us updated

 

That does not sound good. Any plans if the motors junk?

 

sorry to hear that man

 

The shop is having their insurance adjuster come out Monday, so that means they have no intentions of fixing it and are probably going to try and make me an offer on it I'm guessing. I'm not sure how this will play out yet. Other than telling me what I already knew - the motor is done - they haven't said anything specific.

 

Sorry to hear. What did the shop work on a few weeks prior?

 

So still no final word on what the issue is with the motor. The adjuster looked at it today from what I heard, but no report from him yet. Rumor is it threw a rod, but I'm not sure that is accurate. If it threw a rod, I'm pretty sure I would have noticed that. What happened was I noticed the knock, shut the car off less than 5 minutes or 2 miles later, tried starting it a couple of times later in the day for a good listen, left in the afternoon and took local roads - never over 50 mph, and no high RPM - made it about 20 miles and the car shut off. I'm starting to wonder if maybe it was a wrist pin? Also throwing a rod, spinning a bearing - those would lead to a loss of oil pressure, right? Never lost oil pressure. It was fluctuating between half gauge and probably 3/4 gauge, but never dropped. Temperature never was out of norm either. Still very curious and eager to get the Monte back so I can have a look myself.

I'm torn between dropping in another motor or just selling it off as it is. I can't really justify putting more money into it for any reason other than if I don't I'll hate myself for it. This car has been very good to us for the past 221,000 miles. I'm considering another used motor - wondering if the 4t65e-hd might have suffered at all depending on what happened to the engine. Not that replacing the engine and trans would be all that difficult - I had it done once. That was two years ago already - time flies!
