Symptoms don't seem to align with typical thrust washer bearing seize. Usually engine abruptly dies altogether, and won't restart or even crank over until hours later. Engine totally seizes up.

His restarts on its own from its own momentum. It basically push starts itself.

 

Clutch Master 3

There seems to be no specific event or condition that precedes the failure, and no pattern of repeats after an event. I'm kind'a like, "WTF?"

I'm going to pursue a new ECU and a new tune to see if I get this fixed. 8-)

 

That kit's pressure plate has increased clamping force over the OEM one. Correct?

 

I believe so, but I don't know the specifics. LHT put the Kraftwerks kit in about 5 years ago. It has run beautifully up until now.

 

Maybe, have an oil sample checked. Just to rule-out thrust bearing issues.

 

Higher pressure pp means you should definitely do clutch interlock bypass. Each engine start is putting excess wear into this weak link inside our engines.

You should definitely:

1. Do bypass (several options, from paper clip to wiring to another switch, like brake pedal), so can start without pressing clutch.

2. Get an oil sample to make sure you haven't already caused significant damage.

None of this is likely related to your current issue, as problems with thrust bearing typically cause full engine seizure. Then it goes away on its own after several hours. Will do this a couple times before it fully seizes and causes irreversible damage.

But you're not seeing full on seizures that last hours. Above steps will make sure that isn't your eventual future.

 

Yeah. I never thought it would be a crank walk issue either. Was just curious about Windhund's thought. This sounds sensor, tune or EMS related. Perhaps even electrical. Bad ground might not be out of the question at this point.

 

The problem solved. New ECU did it. 8-)

 

Good news! Glad it wasn't the thrust bearing.
