Last night while driving with the cruise set at about 80 all hell broke loose! It sounded like I had a blow out. I pulled over to the side of the road and car was dead. It wasn't a blow out. Tried to restart and it started but sounded funny and ran VERY rough then died. Didnt try again. The tow truck driver suggested vapor lock but I doubt it. Filled up with gas about 75 miles before trouble(water?). Any ideas? Its a SRT 8 with 8400 miles.

Even with one spark plug gone, he has another in the cyl and on a V8 if you lose one cyl, the motor should still run, albeit not smoothly, it should have gotten him home.. I've limped a V6 home on 5 cyls before...

Dsouth, at least this should rule out their "We couldn't reproduce the problem" answer.

Hemi = 2 sparks per cylinder

Chrysler built the Hemi with 2 spark plugs per cylinder and the second spark plug gets it's feed from a corresponding coil on the other side of the engine. Quite reliable. Apparently, the engine is provided with spark on the combustion stroke (obviously) and as well on the exhast stroke (not so obvious).

Problem Analysis

To do any meaningful analysis / suggestions we would need much more detail.

Essentially the engine requires: air, fuel and spark. Start the elimination process and see which it is. Towing it to the dealer and having the engine analyzer attached to obtain diagnositic codes would be the best choice.

If I had to guess ... electronics controlling the timing and spark.

Really bad news!

Service advisor called today (finally)... motor blown. Took five days in service to figure this out. Now I am having to call Chrysler customer service to try to get an extension on rental car.

Has anyone else blown a 6.1 liter HEMI??

Especially when just driving with the cruise on?

Service Advisor says he will have to order a long block. I would welcome any advice from members on best way to handle this repair.

Yes, a member had a connecting rod break a couple of months ago. Try the search, I can't remember who. What caused the failure? This is bothersome, I hope they got this engine sorted out, at least three forum members have had engine failures with the 6.1. I wonder how long these engines will last.

Did they say what caused this to happen?

They did not say except to say it 'threw a rod'.

Even more troubling was the response of Chrysler customer service. They wouldn't authorize the extension of the rental car until dealer service dept. reports exactly what caused the motor to fail. She even indicated 'if the repair was covered under warranty' would depend on the cause of the failure and if the rental car could be extended.

Service dept says the don't know what caused the motor to fail and dont think they ever will. But not to worry another motor has been ordered.

Wow.... I bet you had a bad rod bearing... Would make the same horrible sound if it just were to come apart and may cause the motor to sieze, but would allow a possible restart, unlike if you dropped a rod... Guess a dropped valve could do it as well, with a possible restart...

Let us know what they say actually caused the failure in the engine.... Gotta wonder if it's common with the other failures?

Should be good as new when you get it back, but this repair time should prove to be interesting... Wonder if they have a 6.1l ready to go in the parts depot?
