Engine failure Aston Martin V8 Vantage s
Discussion
Hi all,
I have a 2014 V8 Vantage s with around 12k miles on the clock.
It recently had huge engine failure, failed piston, broken big end, and a load of metal in the oil, so much so that Aston Martin have ordered a new engine from the factory! (I am grateful for the warranty)!
Has anyone seen anything like this? Any idea what could have caused it?
The oil levels were fine and it had a full Aston Martin service history.

What did AM tell you what happened, after all how would we know. If they have agreed to exchange it under warranty they will have done a full investigation as they wouldn't exchange it if they could pin the blame elsewhere. I have a 2014 V8 Vantage s with around 12k miles on the clock.

They must have told you just a little bit of what they think happened.

Yep - happened to my 2014 V8 Vantage S SP10 too. Failed big-end bearing, but fortunately just three months before the warranty expired. Aston replaced the engine under the warranty, but I fell out of love with it after that, and part-exchanged it for a DB9 GT.I have a 2014 V8 Vantage s with around 12k miles on the clock.

Thats interesting!
Wonder if the new engine will be modified in anyway to reduce the chance of this happening?
If I had to pay for the repair it would have been a disaster!
There is some modified part to the oil pump i believe, i would assume (but do not know) that it is a higher pressure relief valve or similar.Wonder if the new engine will be modified in anyway to reduce the chance of this happening?

Without seeing the engine its hard to know, but i have a set of black bearings on my desk, and they are not a quality item.

I feel your pain having gone through similar. However, and I don't mean to worry you but the 'truth' is it wont be a brand new engine, it will be an exchange rebuilt unit and I know this as I had two replacements for same car within 1k miles. Car was actually delivered with big ends knocking and main dealer lied to me with regard to a 'new engine from factory'. Aston only fit 'brand new' engines to cars less than year old. Sorry, but it's true.I have a 2014 V8 Vantage s with around 12k miles on the clock.

the big end bearings are not exactly fancy, very basic two layer glyco type and no location tangs.
I am reliably informed the 4.7 is more prone to bottom end issues than the 4.3 but thay may just be down to the increased rod length.
My mechanic had the remains of several 4.7 engines with a hole in the block, all of them had the same root cause: Failing big end bearings.I am reliably informed the 4.7 is more prone to bottom end issues than the 4.3 but thay may just be down to the increased rod length.
My mechanic told me that even though he had seen several blown 4.7s, he had never seen that kind of failure in a 4.3. Apparently the quality of the bearings in the 4.7 is quite inferior to the 4.3.

Ford ceased production of the 4.7 V8 a few years ago, so presumably few, or no brand new engines have been available for some time.
The rather grandly named 'Aston Martin Engine Plant' (Hall W3 at the Ford Cologne factory) is now used to build engines for Fiestas etc..
Jon - where is the 5.4 litre V12 produced then? I had assumed that it was produced in the same Cologne facility. Do you think that this is like bore scoring in Porsches, seeming to happen more than it does because it is the failures which hit the headlines? There seems to be a lot of it about for a relatively small number of cars.
It may be irrelevant, but when I had the V8VS I was advised not to start the engine periodically during periods (like winter) when the car was laid up, but rather to crank it over on the starter motor before firing it up to circulate the oil.

Yeah I have been told it will be a recon engine cardigankid said:

That remains a mystery to me. Tried to find out, but failed.
5.2 is it? They were being built in Cologne, but then there was mention of it changing to somewhere in the UK.
The blocks were/are being cast in Bridgnorth, from the start of the turbo engine.
I think the not starting during lay-up periods, is just good general practice for any IC engine.
Possibly because of cold engine running and internal moisture creation. Need an engineer to give us guidance about it.

The car has the ability to pressurize oil before start so you may as well use it. the issue is that the crank and the bearing should never touch and its a fluid bearing. over time the oil will fall out of the bearing surface particularly on the upper shell so the shell can pick up on the crank under load before the oil is in the joint.

The bearings dont help as they have no lead layer so are a simple hard 2 layer bearing and have no location tang, as such it doesn't or wouldn't take much contact to spin them.
The 4.7 being longer stroke will put more load on the upper shell, so i wouldn't immediately assume that its the difference in the bearing that causes it.
The early cars with the arrow rods will have a completely different bearing as you can see the location tangs on the very early rods, however this would only benefit the first 1k cars, so a limited win for the lucky few.
