Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

A friend picked up a roller (3.6) that is flooded with coolant. Gallons came out of the exhaust but runs fine. Thoughts?

POST 3 / ORIGINAL POSTEROriginal post

They pulled the plugs and pumped as much out as they could then it started right up and runs fine I'm told...Would a failed AOS also cause something like this?

POST 4Original post

Are you sure it's coolant and not just mufflers full of water from, say, a kid playing with a hose or something?

POST 5Original post

Quotes source post: 15905060

Coolant actually in the cylinders? Wow. Yes, a failed AOS could cause that, or the heat exchanger, or a cracked cylinder head. And yet, now it runs fine? Does the coolant level drop when it runs?

POST 6 / ORIGINAL POSTEROriginal post

As of late yesterday the coolant was not topped off. Will learn more later.

POST 10Original post

How would this work? The only way coolant can get in the combustion chambers, and then into the exhaust, would be cracked bores, cracked head or compromised head gasket. And since we all know it's not the head gasket, that leaves the two other possibilities. On the other hand, there is no proof (so far) that this is coolant. There is a chance water may have entered externally through the exhaust outlets and found its way into any open exhaust valves. Any flood events in the history of this car?

POST 11Original post

@808Bill : since you post a lot of rollers on here - was this one of the cars we've looked at?

POST 12 / ORIGINAL POSTEROriginal post

No, this one in Florida that a friend picked up. I don't know the full story yet, but will share as I get more info over the next few days.

POST 13Original post

(I'll watch for future postings about this anomaly.) Whatever the cause (source?) of the coolant, it will be expensive to repair. At this point, I suspect lingering flood damage, and/or head gasket leakage. relinuca

POST 14Original post

Either they miss-assumed coolant instead of plain water/other liquid, or there is a serious problem (cracked cylinder/head) and they are being overly optimistic (runs fine?) ..

Nope, this all took place while the car was at and indy...
