DB9 engine ticking noise - help please

http://www.ford-trucks.com/forums/1055037-3-0l-val...
Found this thread re the 'fix' for Ford lash adjusters (doesn't sound very convincing to me..) Apologies for it being from Ford 'Truck' thread; no slight intended. I have had not dissimilar noises from the family VW Lupo (additive and a flush of oil solved it, partially) and my old 911 used to make a racket until first blip of throttle ; solved by selling the car and buying an Aston.
Difficult to see how a half engine speed noise could be associated with much other than valve-gear, so right area for further (and much easier) work...

Very impressive Mav. Didn't realize that you could lift up the front of the motor at such an angle as to be able to remove the timing cover in situ. I was given to believe that the motor had to be dropped from underneath.
By the time you are done, you'll know more about taking things apart on your motor than just about anyone here. Do try the cam cap fix mentioned above. I do realize the valve train is different, but the concept is still the same. Worth a go, IMO, especially since nothing else has worked to date and it is relatively simple as compared to the other things you've done.

Thanks DB9VDriver, I may have missed it, or forgotten it, what is the cam fix again....?At the mo I'm looking at the Oil Pump, but it means taking off the cam chains, which scares me a bit ......
..... but how hard can it be .....?
The Ice Lake season is coming up, and I'm considering taking the old 9 for a spin up to Sweden, but I've got a lot of work on at the moment, so I don't know whether to continue with the oil pump, or go out for a sprint through Germany ......

Mav has had his car taken in by a reputable specialist well known in the PH parish; they assure him they know what causes the tick and what it will take to cure it - so he's having them undertake the work as I write. To my knowledge, the issue is related to either engine (over)temps and/or oil supply issues(they believe one or more little ends worn, which was likely caused prior to his purchase of the car). The reason, I am led to believe, why he hasn't commented of late, is that he's got a tad fed up with the degree of negativity directed at him over his efforts to fix his car on his own and share his experiences with the rest of us - which, BTW, I thought was the raison d'etre of this forum.... He has provided more info on the AMOC website for those with an ongoing interest.
As for doing the lashes, I've recently had it done to my DB7V and used a lash adjuster tool (purchased from AM) which enables you to remove the lashes and rockers with the camchain in situ. This considerably reduces the time it takes to do the job and obviates the need to set up the timing again.

I for one applaud his efforts and long may it continue, it's a refreshing change from 'drinkies' and 'spirited drive!!'As for doing the lashes, I've recently had it done to my DB7V and used a lash adjuster tool (purchased from AM) which enables you to remove the lashes and rockers with the camchain in situ.

I hear what you're saying, Navyatco 
Mav's threads were highly entertaining and educational, though there is no single raison d'etre to a forum - some people recently complained about members posting up about their mods and projects, so you can never please everyone.
My understanding, however, is that Mav sought and received advice from an Indy Specialist during his project and was advised of the problem and to not proceed in certain directions. Mav chose to ignore this advice and continue with work that could (and did) ultimately harm his vehicle. I have no idea of the precise details as I am not mechanically minded.
Whilst I respect the courage of anyone who wants to learn about the intricacies of their car, I feel that there may be some who would copy an approach oblivious of the harm it may do
Just to add to the above, whilst I have no issue with anyone who opts to try and resolve issues with their car, I would wager that nobody here (including those that are applauding such efforts) would wish to buy a used Aston Martin if they knew the previous owner had made amateur attempts at dismantling the engine and trying to resolve issues.
Having over 20,000 miles on an Aston seems to make many palpitate so seeing these pictures of your potential next car in bits would induce serious medical issues. Should Mavs Aston ever show up in a dealer the next owner may have no idea of the work that has been done and, whether done properly or not, I for one would definitely not buy a car if I knew that anyone other than an AM authorised tech or a respected independent had touched it.
Of course all that may be academic if the car is a keeper.
