720s New Engine
Discussion
Hi All
I bought a 720s 18 months old with 1300 miles on the clock as.my first supercar
In july i had an engine fault appear on the car and Mclaren came and picked it up the next day. The diagnosis was a hairline crack in the cam cover that would be fixed within a couple of days. I phoned 3 days later and was told the full engine needed to be replaced as when they were replacing the the cover they found the cam shift on cam 2 had also failed so they needed to replace the full engine. Luckily its still under warranty but am that this has happened with an engine under 2 years old and would expect as its a brand new engine being installed they would extend the warranty as they are saying it will still expire on the 3rd year. Has anyone been in any similar situations or offer any guidance on the engine replacement as i have not seen anywhere on any sites where they have replaced the full engine.

Thanks See below from Mclaren, I know nothing about Motors but seemed odd that they would replace the lot
The initial diagnosis confirmed a crack in bank 2 cam cover and the parts were ordered as per Simon’s update to you.
When it came to installing the new cam cover and the associated work unfortunately it was discovered that the cam shaft on bank 2 had also failed.
Following McLaren’s technical guidelines this is not inspected when a cam cover is faulty and is only becomes visible upon the cover replacement.
The only way forward is to replace the complete engine

You will need to write to the mclaren rep. Get the details from the mclaren contact you're currently dealing with.
I did this after my disastrous 720 experience. They had it longer than i did. They gave me a massive discount on an extended warranty to run after the original one expires.
You'd have to be brave or crazy to run one without a warranty.
Thanks very much. I will do just that I did this after my disastrous 720 experience. They had it longer than i did. They gave me a massive discount on an extended warranty to run after the original one expires.
