Aston Martin DB9 camshaft / tappet noise BAD
Discussion
I would say it is the N/S either exhaust or inlet cam etc. The car starts and runs OK with a loudish rattle / tapping when reved up. It did miss a few beats last night, slight miss fire etc.
It is possible that the crank could have gone but it does seem top end to me.
Aston want to put an engine in it for around £11000 but I think it could be repaired with a strip down etc.

It can starve the back 2 or 3 journals, being that there the furthest from the oil pump. It can be worth getting the sump off, tho not an easy job, and re shelling it and then giving it a few oil changes, have heard this has worked in the past as the crankshaft os quite strong. Good luck !!

Thanks. will have a look at this sight. Are they good and come recommended?
Ta.
Yes, they're part of the original engine design team from AM and have gone into business for themselves andare doing rather well. Ta.
I am having a bespoke 6.5 litre engine built by them, they know their V8 and V12 onions! Give them a call, you'll find no-one better as the factory will likely want to put a new or recon engine in.

This video doesn't stack up. I've never heard of Aston V12's in DB9 letting go after less than 10k, so I doubt it is a design fault as this chap seems to want us to believe. It's not the same as the OP's issue - this was a catastrophic failure occurring in a very few revolutions due to oil starvation.And what customer for a low mileage DB9, possibly even still in warranty, goes to a non-franchise workshop (that just happens to be a TV mechanic) with an engine failure? Did he also say at the start that he was going to put a 600bhp replacement in? That might be a clue..
The text below says "for a class action suit against Aston Martin call....". Hmmm.
For the record, I have no association with AM other than being an owner (and have taken two V12's through this mileage without bother).

There have been several failures in the early models, all probably due to low oil level. AM acknowledged this by refitting those engines with a shorter dipstick and, separately, developing a low oil level sensing system.And what customer for a low mileage DB9, possibly even still in warranty, goes to a non-franchise workshop (that just happens to be a TV mechanic) with an engine failure?

So both parties at fault, inattentive owners and a dipstick giving a faulty oil level.
