I'd fill up the system, clean everything off and drive the car (carefully) and see how it behaves.
Oh, Highway 17 to Santa Cruz. The Road of Carnage. No place for rookies.just back from a week of silicon valley driving, including my old commute over santacruz mountains on highway 17 (fun).
And highway-1/big-sur/nepenthe (scenic but not 'fun', due to strong fear of driving within inches of cliffs.)
silicon valley driving is not exactly like LA driving but has a bunch in common. the lane-splitting motorcycles greatly annoyed my better-half on "the 101" as well as on the street with the funniest name of all: "the El Camino".
IMO this is the kind of situation where you sleep on it at least a week and let an answer deliver itself to you. Either your enthusiasm will wane or it'll be persistent by then. "Desire distorts the object of the desire"---believing in this, I let the object spring back to its normal shape and then look it over :)
If it still looks mighty good, well then, damn!
Nope. It's in the design. It's the wrong type of bearing for the job! The IMS bearing is like an axle bearing--a sealed ball-bearing unit. But over time the bearing's grease seals get hard and lose tension and suppleness--they are subjected to 300 degree engine heat. So then regular engine oil enters the once-sealed bearing race and starts to wash the normal grease lubricant away. This regular engine oil may contain combustion by-products and act as a solvent. Sometimes, if only the bearing support stud breaks from this increased friction and heat, you can intervene and repair the bearing--but once the balls get loose or start to break up it sends debris into the engine. Then the bearing race makes contact with the IMS flange which in turn damages the intermediate shaft---this wonks out the valve timing, and causes a valve to piston collision.
There's no real warning that any of this is happening. It is a silent killer. Sometimes you can cut the oil filter in half and see the debris forming, and save the engine; sometimes you will see an oil leak between the engine and transmission, which could be a tip off----OR---it could be a bad engine rear main seal....ANOTHER defect of this engine. So when you see the oil leak, you have no way of knowing if you're going to be replacing a RMS or rebuilding an engine.
Short answer---yes the odds are not great that you'll be bitten---but if you buy one of these cars without a thorough PPI, you're nuts.
Sorry for the long-winded answer--but it's an interesting subject for potential buyers and sellers.
When a company has no vision for its future, it becomes reactive to change rather than initiating it. That's GM in a nutshell in my opinion.
