Are you importing some ramblings into here or is there an elaboration for what you said here?

I'm 95% business here, and the other 5% is only laughing at silly people.

Consider this. Your block wasn't properly lubed and the cylinder walls got too hot. As a result, your piston ring warped or got a hot spot on it creating a vulnerability. As you continue to use the engine, that weakness rubs on the cylinder wall 2 times every RPM. Over time it could theoretically breakdown more and more until it allows oil into the cylinder.

I'm willing to bet most catastrophic engine damage isn't a single event going from good to bad but rather a continuous degradation until failure. I think your mechanic probably agrees.

Could this be checked on if it did happen and an eventual engine demise is inevitable?

Could it be checked during a timing belt change?

oo7spy

You would have to tear down the engine to find piston ring or bearing damage, and it's not worth it. If either of those were to fail, it's cheaper to replace the engine than fix.

Honestly, try to let it go, enjoy your car, and check the oil occasionally. If it craps out 2 years from now, this could be the reason, but there is no point in sweating it now.

RL09

Oh agreed. But I must know all eventualities. in this case, if damage will show later, i'll need to put them on notice. once the damage becomes clear, to try and get them to replace the engine.

The limit where i am is three years after you put them on notice.

I should've have to pay for a new engine in two years, they should wouldn't you say? they said they changed the oil, and they did not. I shouldn't be expect to worry about the oil within 3 months of purchase.

oo7spy

I think bearings and piston rings are the most susceptible to damage from low or bad oil, but I'm not the best gear head when it comes to internal combustion engines.

One thing what you can do is pull out the plugs and use endoscope to see what cylinder walls looks like.

Did a flush 2 days ago. They poured a bottle of liquid in there, let it stand 10 mins, then drained the engine. That's a flush?

Gonna check if it burns oil and if so, endoscope it is.

oo7spy

Flushed what with a bottle of what in where? Drained the engine? What are you talking about?

RL09

Then poured a bottle of amsoil i think, just checked the bill. Then let the car stand. Then they drained the oil, and replaced it with the filter.

oo7spy

No, that's not a flush. That's a waste of an expensive, top of the line oil. Not a lot of point in trying to flush engine oil IMO. It would be much more worthwhile to do a change, drive a couple hundred miles, and then do another change.
