This was filmed at SUPERCAR GARAGE in Kennesaw GA. A big thanks to EMF AUTOS for making the 400 mile round trip several times to capture and share this engine rebuild on his channel.
Kevin is my next door neighbor!!!! He is an encyclopedia of car knowledge. I have seen Ferraris, Lambos, R8s, Bentleys, etc come through and get repaired by him. What an awesome video!!
I was there at the shop when this was happening. Huge undertaking. Atlanta is lucky to have access to these guys McLaren work outside of the dealer. They’ve worked on my McLaren twice and I will be going back in a few weeks for a tune. Just don’t go out for all you can eat sushi with them though.
well done boys , my names SEAN and i used to run a pub called the bleak house in woking that all the McLaren boys used to use for there lunch breaks , remember Gordon Murray bringing down one of the first road cars to the pub car park !!! nice to see you boys the other side of the pond looking after them . 👏👍fantastic work
Did you have to re shim the valve ? Also did the car have a tapping sound when it was running I have been diagnosing my 570s it has a tap sound left bank last cyclinder wondering if it’s the same thing
No need to reshim, I never heard this engine running prior to me getting to it. The last car I heard tapping had a broken cam phaser which you can hear in the cam phaser specific video I did.
if you want to seal a split line without disassembly, a guy put us onto stuff aircraft techs use called aerospace sealant thats fuel rated, the B1/2 being the faster setting than the b2. Drop the oil to stop the weep for a day. clean and scrub the line, mix the two part sealant and apply and let sit a day or 2 without the oil in it, and it wont leak a drop , the guy showed a seam he did in the late 80's and hasnt leaked a drop since, You get it on ebay thats near life limitted out.
regarding some of the grime on the gearbox, there are 3 breathers in that area, they look like small caps/bolt. They will 'breathe' residue onto the gearbox casing and normal.
Excellent video! So the shim for the cam follower came out which broke off the tooth for the cam position sensor? Did you have to reset the code on the ecu?
Yeah, pretty crazy how a series of things happened which lead to that. If the arm didn't break the shim wouldn't have come out and wouldn't have hit just the right spot at the right time. OBD2 scanner clears codes and it's good to go, error free now.
I have the utmost respect for you guys and your work. I’m a subscriber an super impressed. Don’t mind if I ask what the hell did this cost???? Also guy in wheelchair wishing you a speedy recovery. You guys ar quality content.
We did more than just the initial fix, cam phasers were a do it while you're in there job. The only thing that needed attention was the cams and finger follower. This video is a year and a half old now, he's long since recovered.
I haven't had to do them in a while, the last one I did was on a time constraint so doing a video wasn't possible. Doing a video on something takes 3x longer than just dong the job. The next opportunity I get to do one I will.
The car wasn't running when it came in but it's my understanding he had been driving it for some time with the check engine light on before that. It was a cam related code, I don't recall the specific one as everything was cleared by Kevin shortly after we got it started.
The warranty was declined before the car was even looked at. CEL was a camshaft fault and they declined it because a prior owner in 2016 went beyond the oil change interval, not mileage, one time.
When looking at pre-owned McLarens, how do you know if the car ever went over the McLaren limits for warranty? If the car is currently covered by the Extended McLaren warranty, does that mean you are guaranteed warranty coverage on non-excluded items?
Where did you get your torque specs, where did you source the camshafts from and where did you get the cam alignment/hold tool? I apologies if you mentioned it later in the video but I didn't see it mentioned when you were at those steps. Oh, and costs of those items would be great if you're at liberty to discuss.
I've got a spreadsheet of all torque specs someone out together. Engine parts came from Motorcars of GA (McLaren dealer), cam alignment tool came from XPRD. Kevin handled all the parts acquisition so I didn't see the invoices but the parts used including cam phasers were around $6k IIRC, maybe $8k
Nice job 👍 The broken finger follower was most likely caused by excessive revs/revving at some point. Do you know the complete history of the car? Even if the owner/s is careful, it only take one rogue service tech or valet parker etc to show off "making flames" and the damage is done!
I only know a vague history of the current owner, who isn't the bounce off the rev limiter type. McLaren's aren't like many other brands in that if it can damage it, it won't let you do it. I think it goes back to a casting issue at the factory.
Meanwhile in the UK, a friend runs an independant Mclaren shop and he says over-revving from cold (not red-lining or anything) has been a good source of work for him!
hello I seen your videos very professional I live in Austin for oil change and transmachine oil change and check up my mclaren 570gt where is your location I couldn't find if you could please let me know
So each manufacturer decides what Cylinder number 1 is? I just did a valve job/ rethread 5 stripped holes in the head on my 07 R6 (Goodness it's so much simpler than this beast of an engine) but Cylinder number 1 is the one furthest from the sprocket side of the cams and what you call cylinder number 1 on this McLaren engine is Cylinder number 4 on my R6. TDC for me is set off of the cylinder furthest away from the timing chains. I guess there's not "common practice" for that sort of thing? Interesting
V8's are commonly the first cylinder on the left when looking at the crank sprocket side. 4 cylinders are commonly as you described. Not to say all are that way though.
@@McMedics That is very interesting! So it would be 1-4 from sprocket moving away and then when you switch to the other side of the V does it start over at 1 again or jump to 5? And does it travel back towards the sprocket or start back at the cylinder near the sprocket on the other leg of the V? I would think it would go to 5 because there's not like an exhaust bank side of the v and an intake side of the v. There is intake and exhaust on both banks. So Im wondering if they have each bank distinguished somehow (which would allow starting over at 1) or if they keep counting up to 8 and which one is 5? Sorry I'm new to the auto world and am LOVING every second of learning about this. I hope to rebuild a McLaren one day!
The same worry should be had for an F150, they're more prone to failure. Warranty wouldn't cover it because a previous owner 4 years prior waited 14 months to do an oil change.
@@McMedics oh for sure I’m pretty religious about my oil changes on all my cars so far, thanks for the quick response! And I hope everything proceeds well because I’m looking forward to getting to experience the 12c! I did watch the entire video… I’m sorry if I missed it but are there any telltale signs or excessive noise to look for because the one I’m looking at has about 20k miles, so I guess I would just check the service records for time and mileage between changes
@@topend2282 Yes there are some signs of current failure, like loads of misfires, but primarily codes about the intake or exhaust cam position. If you know what to listen for you can hear a difference in the exhaust and a clicking in the cam phasers.
Very interesting and informative video. Well done for tackling such a major project 🫣. I used to live near Kennesaw, ATL and now have house in Hilton Head, SC. I live back in U.K. and have 570 Spider here but just musing about if I could get a 12C and use when over there ( approx 5 month a year). Many thanks sent from England 👍🏻
You have to have a McLaren warranty for them to not cover it. I'll be doing a video about warranties this week, both McLaren and third party and why you shouldn't have one or why you should.
The cause in every case we believe to be from poor oil condition over time. Example, not checking level and running it low, or going over recommended interval. The wrong oil could also do it. The owner of this one hadn't had the car for years to know how that aspect was managed.
I've been a motorsport enthusiast since I was 8 and am in my 50s now. I just don't understand, in this day and age, with what we know about metallurgy and design why we have this kind of ish. Car costs as much as a house yet has problems like poorly design crapboxes. No thanks; but if I ever lose my mind and buy a modern exotic, Ill get it to you.
There isn't a single engine from any manufacturer that is impervious to faults. You also can't prevent every engine from poor maintenance. Many problems are caused by oil starvation, because of not checking the level or infrequent oil changes. In many cases the cars that are so expensive are that way because they're leading in technology and have the lowest production. That also means that tracking down a problem and fixing it may take longer due to a lower sample group. It's the price to pay for having the best, really. Though worth noting, the biggest manufacturers also have these problems and they're making millions of them.

Could you add a video of changing plugs without dropping engine. I have found no video out there which shows this.

Phenomenal work!!
If you had to identify a cause; Design, flaw, or oil starvation?
With how the follower broke I'd say part defect.
Was the reason for the damage ever understood? Early on a lack of cam lube was hinted at but....?
Great technicians and team work it must take years of experience to take on a job like that
It's not something you just happen to do. You've gotta know what you're doing on those cars specifically.
Thanks for sharing.. Very interesting.
Sean, amazing video. Fantastic, may I ask what codes were showing on the ecu due to this broken follower? Also how was the engine actually behaving??
The car wasn't running when it came in but it's my understanding he had been driving it for some time with the check engine light on before that. It was a cam related code, I don't recall the specific one as everything was cleared by Kevin shortly after we got it started.
ODB CODE: P0391 Exhaust Camshaft signal implausible
Good job guys!,
How long did it take to get the engine out, change the cams, then get it back in.
30 hrs
Love your videos, definitely given me confidence in owning my exotics long term. BTW why did they refuse warranty? Tune?
The warranty was declined before the car was even looked at. CEL was a camshaft fault and they declined it because a prior owner in 2016 went beyond the oil change interval, not mileage, one time.

If it's currently covered it's within their limits. Anything not covered is simply not covered
I am in awe
Great work. Too bad you guys arent in NY
I am sometimes. I travel by demand.
What was the cost for this job?
Where did you get your torque specs, where did you source the camshafts from and where did you get the cam alignment/hold tool?

how much did you bill for that ?
Hello Sean. Great work. What do you all charge for a job like this? Thanks!
If it's just cam phasers around $10k

How can i get in touch with this mechanics?
where is the ac ports on a mclaren 520s?
Left side, accessible from the small triangle undertray by the rear wheel.
@@McMedics would have been helpful 1mth ago 🥹🥲 lol i found it shortly after, thanks you.
Wow! Great job. Price of this job?
$24k or so, parts and labor, over 40 hours labor
@@McMedics Thanks, that's why I'm a little scared to buy a 570S
Engine out rebuilds are extremely uncommon.
valve not bent?? very lucky!
I was watching a Lambo getting dismantled the other day and I believe he said the cam phasers were 10,000! They looked the same.
They're similar
How can i get in touch with you for a repair?
can you explain the warranty rejection?
In 2016, a prior owner of the car went over the 12 month recommended oil change interval by a few months, only a few thousand miles put on the car.
The comments: "How dare you make this guy work in a wheelchair!!!"
The guy in the wheelchair: "Hehehe I get paid per hour" LOL
Just see another vid the new follower are dark in colour comes with a special coating it's been upgraded due to this problem

According the oil leak on top of the engine , it might be a cracked crankcase vent line or a defective air oil seperator!!
What we found the oil to be from was actually the drivers side axle seal. It was sending oil EVERYWHERE spinning around.
I’m looking at a 12c right now but this is the only thing that scares me… maybe I missed it but why wouldn’t the warranty cover this!?

So was the lack of oil going to the follower ever diagnosed? Looks in some way that you fixed the symptoms but not the cause?
