PLEASE Share this video! The message is real!

Everyone be aware! The owner of this car was responsible and purchased an extended warranty when he bought this car, but when he had a valid claim they denied it on a technicality due to a previous owner performed an oil change "4 months" past the recommended 12 month interval! FYI, the car had only covered <2k miles since that last oil change! (We all know the "late" oil change was not the cause of the issue)

Basically if you BELIEVE you are covered by an extended warranty, you MUST have proof that EVERY required service was performed ON TIME and WITHIN THE MILEAGE, by EVERY past owner since the day the car was new. IF you don't have this documentation, the warranty company WILL deny your claim.

FUNNY how the warranty companies don't require any proof of maintenance history BEFORE they accept your hard earned money to buy that expensive warranty that they easily will deny later for the same reason (and they will not refund you all of your warranty premium either!)



AND, once he found out this repair was on his dime... His dealer (the car is from the northeast, USA) told him he had to get a new engine, and "IF" they did attempt this repair his engine they would offer no warranty or guarantee of the work!

WOW!

Thank you! To the owner for trusting us to put this awesome 12C back in service with its original powerplant so it can live on to still dominate the streets!

Hey man, good to see you in good spirits and the car is up and running again, how was the engine running with the broken follower? Also do you remember the code that was showing on the ecu at the time?

assuming this is a 3rd party warranty company?

does mclaren themself offer one?
McLaren does offer extended warranties, with a few caveats. YOU have to pay the dealer to look the car over and pay for anything they say needs to be fixed before they'll start a warranty period on it. It's quite expensive, I hear around $7k a year now. So, they might hit you with say $4k to allow you to give them $7k, and that's assuming your VIN hasn't been blacklisted. If you don't have the dealer service it, void. If you do any modifications, void. They don't cover quite a few things, like accumulators or cam phasers.

One intake valve wasn't opening so there was a power loss but it wouldn't have been knocking or anything. Consider this though: 1 valve not opening out of 16, would you notice if you weren't trying to make maximum power?

understood.

another q, i see you said it is important that service was done within the mileage point... what does that mean exactly? I leased my 600, first service due in June, i can't exceed a certain mileage before that point?

I have no idea because I did not start it before the repair. The PO said it ran fine, but always had a CEL on.

ODB CODE: P0391 Exhaust Camshaft signal implausible.

If your recommended oil service is "every 12 months OR 10k miles", then even if you only drive 2k miles in a 12 month period, you better change the oil BEFORE the 12 months period.

AND... I f you drive 11k miles before you change the oil, even if it is less than 12 months... you have potentially just voided your warranty.

Your lease limitations are different than the vehicle service interval.

I think we should be thankful for people like Kevin and Sean. It seems like working on McLarens was something no one knew anything about and dealers were reluctant to reveal. I’ll be honest. I chose my f430 over a gallardo because of the information on working on them that was available. I was a bit hesitant about getting my 12c but knowing the growing info available and having Kevin nearby swayed my decision.
The only problem is I enjoy driving my 12 c so much I’m literally going to have to force myself to drive the Ferrari to keep it from rotting from sitting in the garage.
I just got headers for the Ferrari because I know it’s just a matter of time before the factory manifolds crack. I’ll probably have kevin install them.

Its not really working on the cars that is the issue its the parts availability and price which is the real issue here.

There is something to be said for available information regarding the work, like torque specs, proper diagnosis, and what tools are needed (like if a special tool is needed). Parts availability I haven't found to be an issue, the price of those parts is what can be discouraging. That's more of a US issue than a brand issue, I'm finding.

Nice job. Guessing you quickly realised the engine is actually 45deg ATDC in the cam locking position 😊

I sell the parts and service information for all repairs, if you are ever in need. I've been available to the community much longer than any vendor on this forum. I even sell the tools that allow this work to be done. For example, this video uses my cam locking tool (shiny bit holding cams in place), which is a much more elegant design than the one mclaren techs use.

It's great that you're giving owners another option. For my previous cars, I've always preferred specialists to main stealers.

One request though - please keep the music volume down relative to the speech's.

Some may like to see an approximate price for, say, cam phaser replacement. I assume that it'll be a fraction of what a dealer would charge.

You can call me for parts, service information and you will LOVE my prices.

And yes shops like mine have McLaren Level tools like the Camshaft alignment tool seen in the video!

Would you believe the music is 28 dB lower than voice? I edit on high end speakers, with bandwidth, so if you're watching on something with limited bandwidth like a phone or tablet it may cripple and/or emphasize certain frequencies. What were you watching on?

I’ve seen a lot of tips and fixes here over the years, but nothing of this magnitude. I have to say I was frick’n impressed. I know Eddie, and he is an amazing mechanic but the three of you together seem unstoppable. Not only did you take the entire engine out of the car, but then disassembled it, identified the problem and fixed it. Then you actually managed to put that rats nest of wires and hoses back together again without ending up with extra screws and parts when it was done. LOL. And it fired up the first time? 😎 and I was wondering if you could fix my headlights 😜.

In all seriousness you did. McLaren a HUGE favor. Their solution was to replace the engine. Fine, but without knowing what went wrong they can never make improvements to prevent it happening in future builds or future designs. In the medical industry, if we have an issue with one of our products and we don’t understand the root cause, we open up what is called a CAPA (Corrective Action/Preventative Action). What can we do to correct the issue in current products if necessary and what can we do in the future to prevent it from ever happening again. You just showed McLaren a potential weakness in the engine design that they might be able to prevent with a material or design change. They just got that for free from all of your hard work and collective expertise which it seems they were not willing to do.. Maybe they should show you a tad of appreciation too 😉. ....... hold your breath. Lol
