That is Jay Leno standing next to the BMW V12 extracted from his McLaren F1. Calling it "The scariest thing we have ever done here on Jay Leno's Garage," his mechanics pulled the motor to replace the Vanos unit, which was leaking.

His fright is our gain, though, as Leno gives us a tour of the 627-horsepower, naturally-aspirated 12-cylinder that powered the very car that taught us new ways to dream about supercars. The motorhead's VIP tour happens in the video below.

      More proof that Jay Leno is a real car guy! Dropping the engine on one the most legendary cars in history for a tune. Those who think this is killing its value, Jay's F1 probably has more miles on it than any F1 out there. I think he's more worried about fixing the problem than ROI. Thanks, Jay for this intimate look at your beautiful car's nether regions!!

      I love the Mclaren F1. I'd seriously die a happy man if I get the chance to drive it once .

        Think you could handle the car? I know I can't, it's out of most people ability. This is some serious hardware without any electronic nannies.

        Amen to that. Timeless. The GTR version haunts my dreams. =)

      That has to be one of the best looking engines ever.

      Effing vanos units. $4k on an M5 after warranty, maybe $1000-2000 in parts for an unauthorized by BMW rebuild. Glad Jay can afford to replace a pair on his V12!

      Holy crap... the entire drivetrain, including transmission, weighs less than 500 lbs? That's just insane.

        The whole car weighs 2300lbs. Also just as insane.

      The reason that car was so groundbreaking is 15yrs after the last one was built it is still competitive against the best anyone has to offer. Even the engine still looks completely modern and high tech.

      Vanos actuator needs to be replaced? Yup, sounds like a 90's BMW motor to me. It's really weird looking at the shot with the open valve cover and thinking "heh, I remember all that with my old car", then remembering it's the heart of a freaking McLaren F1. On a side note, I wish there were more videos of cars like this opened up. Don't get me wrong, cars look/sound great (especially this one) but I find the technical/geeky/James May part of the cars just as fascinating, if not more.

      Must be nice having a garage like this... where you can just "pull out" any engine that might go bad. This is as much "garage porn" as "car porn"... lol
