Dropped cylinder wall?

What are the symptoms of a dropped cylinder wall on a 3.9EFI?

internal coolant leak...

1) losing coolant w/ no visible sign of where its going
2) white smoke at tail pipe
3) sweet smell at tailpipe
4) Coolant mixing with oil -- drain you oil.. capture the beginning of the stream into a clear container... and see how it looks, the coolant will separate onto the bottom.
5) pull a spark plug, look to see if it looks 'steam cleaned' compared to other ones
6) misfires on a particular cylinder
7) erratic idle


Another test I learned was to get a small piece of paper, roll it up, and stick it into the spark plug hole and pull it out and see if there is any coolant on it..

Almost all of those can be a sign of a leaking head gasket as well.... so other than a complete tear down, the only way I know to see as slipped liner is by pulling the oil pan... I've heard though, that sometimes a slipped liner is only visible when the engine is hot... so some mechanics get the engine warmed up, then drain the oil and drop the pan to see if it's slipped..

And when you pull the headgasket look for a second ring sort of an impression when the liner is where it slipped up and down and hit the gasket.

Has any tried to use a borescope to inspect the linners? I'm not sure I have this problem yet. I can't get any heat and the engine temp is extreamly low.


Thanks

Did you try a compression check of the suspected cylinder?

I would get a block tester kit (got mine at NAPA, about $50). It will check for exhaust gases in the coolant and is incredibly easy to perform. All you will need to do is basically put it on your coolant resevoir and fill the tube with liquid. Takes just a minute and I think is vital for any roverites garage...
