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.

Driving home on the I-10 my 01 base Box lost power. I pushed the accelerator and it responded just not the way that it should...sluggish. I started to pull over and the CEL came on. I made it to the shoulder and the engine stopped. I called AAA. My Box was leaking oil...a lot. There was no warning. The engine just lost power...no noise, no rattle, no nothing. The odometer showed an onimous 129,666 miles.
Would a sudden RMS cause the engine to lose power? Or does this sound like an IMS?
Ims maybe. Sounds like you now have a hole in a piston or lost a valve or something like that. Was the oil coming out of your air filter or air filter box?
Didn't have a chance to look at the plugs or or the air box or anything else. Simply had the Box towed to the shop. I'm sure that they'll take a look at it early next week. They did notice that the oil seemed to be leaking from the RMS...right between the engine and the transmission (5-speed).
Just wanted to see if this had happened to anybody else and what were the results.
Well, the economy the way it is and the furloughs cutting into my pay substantially, I'm hoping that it's just an RMS. I think I needed a new clutch anyway. That being said, I'm preparing myself for the worst....parking my box and finding a new form of transportation.
Still, has anyone had an RMS fail that would cause an engine to lose power?
The only way a RMS leak or failure can cause an engine to 'lose power' is if the seal allowed all the oil to leak out and the motor seizes.
Time to grab your money gun and prepare to shoot some big bills.
I doubt you get off anywhere near cheap this time.
Good luck!
The fact that the failure was silent is a clue but it might not be a good sign. If the motor won't crank it might have seized due to a major oil leak that led to lubrication failure (just a guess).
If it cranks and sounds normal (normal cranking speed indicating good compression) then maybe AOS which led to MAF contamination and RMS failure (another guess, but less likely than the first one).
I'm no expert, so take this with a grain of salt.
The AOS was replaced 10,000 miles ago at 120,000. It allowed oil into the crankcase and seized the engine. Oil was dripping out of the exhaust. O2 sensors were replaced. Guessing that rules out the AOS.
Had a restless night preparing myself for the worst.
