All about McLaren engines

In this video we explain about the various engine issues that can happen, their causes, how to avoid them and cost to fix

[@HANNON1066]

I can honestly say I would not own a McLaren unless it was checked prior to purchase, serviced, and warranty by Thorny.. 👍👍

[@Zeebo1uk]

I concor

[@VTrack650]

Thank you for this. I always make sure oil is well up to temp before even considering getting into the upper revs.

[@HawkMillFarm]

Good video, I think the take home messages apply to us all never mind what we drive. Mechanical sympathy helps longevity.

[@andrewfrancis3591]

Thank you for these videos. Out of my budget at the moment, fascinated.

[@supercaradventures2219]

Brilliant and informative as always!

[@ingenere]

Great info John. Thanks for all you do for McLarens and owners.

[@johnmorrison27]

Another great video 👍

[@findpatienceinlife9485]

Great video as usual John. Always interesting when the bean counters get involved! Great advice as always 🙏

GreT info thanks

[@sanglemalt]

It is good to be aware of these issues. Thank you.

[@renemacias6356]

As always another great video! Just wish you were in the US to watch after my McLaren.

[@NuttySwiss]

Thank you!

[@tuomasholo]

I’ve learned a lot from this video. Thanks

[@PAC9322]

Thank you very much …🥂

[@BubuBarong]

Great video sir! If I may... Invest 30 quid in a good microphone, it would make your videos much much better and easier to follow! By the way: I'm writing from Italy... Any of your trained technicians over here? Cheers and keep up the good work!

[@ThorneyMotorsport]

Appreciate your comments, I use a Insta 360 camera for these as I lack the time to really put into post production, the 360 allows me to just plonk it down, talk to the camera and upload. It's not perfect but if I add more time for things like audio I can see me never getting the time to do the videos at all I'm afraid. We are looking for international partners, Germany and Switzerland are first but looking for Italy too

[@adonistorres1047]

@@ThorneyMotorsport Hey can you tell me what’s the difference between the McLaren M383tq P1 engine and the M383t e engine used in the 570s-675lt?

[@john1703]

All machinery needs adequacy of design, construction, operation and maintenance. Screw up any one and it will bite you in the bum. The third and possibly the last one are down to the owner/operator. However, if there is no oil dipstick, I suggest that is a design fault.

[@gegarza]

Great video and very informative! Subscribed! With the huge and detrimental impact low oil pressure can have on these cars, it would seem reasonable to have some type of low oil level warning system built in. Regardless, I check my oil level on my 570S every 500 miles. Typically end up adding about 1/4 quart.

[@executiveinvestments]

lol. Low oil is bad for any engine.

First rule in engineering manufacturing, drawing control! Let's all sing off the same hymn sheet ;-)

Hello John! I recently bought a 2015 650s coupe with less than 2k miles on it. The previous owner barely used it and the car is almost new. Before I bought it I drove it for a couple hours and I noticed some sort of weird hydraulic pump noise coming from the back of the car when coming to a stop. Now, I live here in Dominican Republic and we don't have a Mclaren dealership. The only choice we have is the Mercedes dealer which is the only authorized dealer by Mclaren to sell and service these cars down here in the DR. So I went down to the Mercedes dealer where they have a couple of technicians working on these cars, and I was told by the techs that the noise is quite normal on the 650s & 720s, and if I recall correctly, they mentioned that is something related to the aero system. But since you are THE EXPERT on Mclarens, I would appreciate your input on this particular situation, because to be quite honest, I don't really trust much their expertise on Mclarens because for me, they are simply Mercedes techs with some Mclaren training. I love your channel and the way you explain everything about these cars. Best regards, Levi Garcia

[@johnthorne2920]

Can you video the noise and we can have a listen for you.

[@user-hc6ss8of5k]

Hi John I cant find your video on how to do a cold start adaptations re set !!!

[@paguk2000]

I was told 75% of engine ware is when cold, You never rev the engine hard when cold

[@user-vq3lz3sx7y]

Hello. Can you please point me to the video where you talk about cold start adaptations? Thank you.

[@SilverstoneShootingCentre]

Not sure we've done one, but its simple enough. Stone cold car, start it and immediately drive the car in 5th gear under 30mph for as long as possible. Thats it.

[@McLarenGTFast]

Any specific number of times?

[@klausspindler5085]

I am considering to by a 12C - would you go for a 1/2014 with 72.000km or a 2 years older 1/2012 but having only 25.000km (same price)?

[@SilverstoneShootingCentre]

Wouldnt really care, more about condition rather than mileage.

[@andypandy9931]

It doesn't seem a good idea to me to make the liners from aluminium, were they coated, Nicosil etc?

[@ThorneyMotorsport]

There were different versions from different suppliers over the years some better than others

[@roxind]

If not mapped, those engines should be protected from over raving by electronic safe guards, isn't it?

[@mannysingh6618]

Agreed. Cars are automatic anyway, how can they overrev?

[@1985gooz]

Cold start adaptations work up to 50c water temp. Not at.

[@ThorneyMotorsport]

Yes of course

[@shoobidyboop8634]

As an American, I can tell you it's our Constitutional right to overrev the engine. I can't recall which amendment, exactly, but it's in there.

[@jesvans]

[@AuslanIz]

To summarize: Dont be a show up and an id**t! And learn about cars coz money dont buy skills and knowledge! 😄😄

[@arzemagic]

There is one Canadian KZbinr, it doesn’t seem to have any mechanical sympathy for any car really.whos modified 720 s is belching out a white smokescreen

[@kevinmoore7255]

It’s doesn’t look good! McLaren seem to have as many issues as JLR cars and that’s saying something
