Does anyone have a contact number or email for the NHTSA people looking into this? I filed a report a long time ago but I'm pretty sure I used my Duke email account which has subsequently been shut down since I left. I would like to send them this little gem:

I don't recall seeing the actual hoses fail. So, I took Kevinp's lead and bought the BSP hose ends.

The mechanic at Sports & Specialist Cars, Hopewell, NJ has not seen a single line failure.

Mostly, he sees oil coolers leak.

While clam is off, am replacing the radiator, also prone to failure. The Wizard Cooling radiator that 407driver recommended is an impressive unit, $430 + frt.

Prorad, via Sector 111 was ng for me, with failures already reported.



I drive all over eastern half of country. didn't want to get stranded or lose an engine. Soon expect to be driving farther west. Pretty hard to remove clam on the side of the road....

Not sure if this has been posted already, but there is a 2004 service bulletin from Lotus regarding these oil leaks. Anyone who downloaded the PDF manual has a copy. I've attached a pic of it below.

That's a different issue and was resolved. Also failures didn't result in the massive oil loss that is typical for the oil line separation issue that NHTSA is investigating.

Here you go; actual line failure.

https://www.lotustalk.com/forums/f312...-repair-90292/

Cooler leaks and line failure make me nervous too but I imagine the volume of oil expelled to be so much less that the risk of major incident is probably much smaller. Nonetheless, I'll be replacing lines before I put the oil coolers back into service.

Leak at the oil cooler

After reading the reports, I dug under the car and saw oil seeping from the front driver side oil cooler. I pulled the fender lining out and saw it was a bit messy, but the crimped OEM hose coming from the cooler was clean.



I suspect the leak is from the hose in front between the front two coolers...the one, of course, that requires me to take the whole front clam off. Grr.



I tried to inspect it through the front small grill...it's difficult to see, but it looks like the "sleeve" over the hose has some oil seeping out from under it.

Is there an easy way to tell if this is from the hose/fitting or if the cooler itself is damaged?

Cheers all,

-Erik

I believe you can get to the center hose by removing the front under tray.

It is a shame to still see so many of these incidents and Lotus has no response. My story is here, includes pictures.
  • Year: 2005
  • Model: Elise
  • Date failed: April 2008
  • Location of failure: I-95 between Baltimore and DC
  • Mileage: 19K
  • Daily driver: Yes or No
  • Track use: Never
  • Other description or info: Pretty sure my engine was damaged, Lotus said engine was fine, however now at 35K, and my drivetrain is fairly noisy. My guess is it wore the camshafts when the sump went dry.

That hose is on its way out. Yes, you should report it. Also should think about fixing this before the car is driven much.

I had a leak at the same connector, and fixed it. The following thread has a detailed description of how to replace the connector yourself, and a dissection of the the stock connector.

Front one gone now

Repaired the rear crimp failure, will post pictures of how later, but it was easy and seems to be working quite well. Unfortunately something blew up front now. Reported the rear failure, looks like I'll have to report the front now. Engine still works, good thing it a Toyota.

Found out from a local British Car repair shop that they just fixed another one last week. Likely the owner doesn't even know its an issue. Will be trying to contact them to have them report as well.

someone mentioned to me that the valves get really loud when the oil pressure start to drop....did you guys notice that when your oil line blew? this could be an added audio warning because we are not always staring at our instrument gauge when we are driving..

I did notice the valves making a lot more noise. Good time to shut the engine down.
