The Dreaded DB9 Engine Tick!

[Olivera]

Reconditioned by who? Doing a proper job is going to be a fair whack on a V12.

[andyvvc]

Gutted to hear about this the other week chap. Had a long-ish chat with Myles - were local so if we can help let us know!

I'm an expert in:
Coffee making
Coffee testing
Hob Nob evaluation and disassembly
I can also possibly wield a spanner or hold something up for you engine-lift etc related lol

It's a cheap(er) fix than if the engine had imploaded. And once fixed, you will have a very desirable DB9 (that you won't want to sell anyway)

So I've had a chat with a few people and I've decided to remove the engine in my garage, put it in the back of my van and get it reconditioned.

I thought you might end up taking this route Paul

I wish you the best of luck and, having seen your rear subframe restoration thread, am confident you have the skills/dedication to make it happen.

Who is going to recondition your engine for you and what specification is it going to be built to?

This story was not read off the internet but a discussion at a inde car garage, the Vanquish ended up with him and he repaired it, I don't know any other details.

When you say repaired? What was the repair carried out?

I'm not aware of any engines being available unless you find one from a crashed car?

This is why Richard has worked hard to develop this solution. It is also why Barry Hart is interested. He sees it as a continual offering for any V12 needing a rebuild. As you cannot rebore them oversize. This is the only solution out there for damaged bores.

I’m sure you know but a 2 post lift needs to be secured in a substantial thickness of concrete.
Good luck with the project.

You can get one post lifts that are mobile. The double legs reach right under. 240 volt also.

You can also my the twin scissor platforms that are free standing. Not sure of they would go high enough to extract the V12 though.

Hi Andy, yeah thanks, I know your only round the corner, Myles has already come round for a chat.

Yeah massive job, I'll start it in the summer as I've got a few things on at the mo, getting the ramp installed first, plus I need to know if the concrete in my garage is suitable, might need to cut and install new footings for the lift first, the list just goes on........

Tell you what, when this is all done (probs early next year) we'll go out for some ace run outs!!!

I believe the owner sourced a replacement engine from a breakers yard and was installed successfully.

That wouldn’t work. You couldn’t separate the body from the powertrain.

Yeah thats right, I'm installing a 2 post lift.

Baz Hart has done stirling work in the Porsche community with his wet liner solution to the M96 & M97 bore-scoring issues.
Coincidentally, the Ford Duratec V6 upon which the Aston V12 is based, was initially designed by Porsche who then sold the rights to Ford, when they decided to use the VW V6 in the Cayenne.

Admittedly the causes of the issues are quite different but the solutions largely the same.

An interference fitting of liners to a block at ambient temperatures is sub-optimal but faster & cheaper relative to heating the block & freezing the liners -something which would be done in a hand built engine or a race engine & not a production line.

[VanquishRider]

Not quite.

Porsche was employed to design the modular system that was used on Duretec engines. But it was Paper "Work" no metal was used.

If you ask Richard nicely he will give you the full story. He has it on a speed dial cut and paste.

Agree, just pointing out you can get a 1 post system.

[paulrog1]

Update.

Definitely going to take the engine out at home.

I've spent sometime sorting out the garage and this week just installed a 2 post lift.

I plan to have the engine out by Christmas as I always have loads of other stuff to do.

Plan A is to have the engine stripped down and repaired, but if too expensive - Plan B get a replacement engine from a breakers yard, but I definitely prefer Plan A.

I'll update later in the year

Good luck Paul, looking foreward to your progress reports. Any chance you could post on you tube similar to what GB9 garage did ?

Hope it all goes well Paul. Garage looks so clean and tidy, puts my efforts to shame.

[karatemaserati]

Goodluck and sorry its happened..

Have you thought about turning it in to a 7.3 while you are at it? Surely wouldn't cost much more and then uv have something really special.. every cloud and all

[Gazza450]

That sounds like a big project!
Two post lift looks great but just remember that you may have to support the back of the car when removing the engine, as all the weight balance will transfer to the back when the engine is out.
Did you have to reinforce the floor slab or foundations to accommodate the holding down bolts for the posts?
My car is currently with Martins Aston Services for a rear sub-frame refurb, suspension refresh etc. They have had to independently support the front of the car when back is stripped otherwise the car would have been very unstable on a two post ramp with the gearbox and subframe removed.
Good luck and look forward to hearing how you get on.

Hi Paul,

I found the procedure to get the engine out of my DB9 pretty straightforward and follows the DB9 manual faithfully (google and you can find the thread on the other US based forum).

I built some wooden frames from 4X4s on dolleys to support the engine & tranny/diff. (in lieu of the nice metal ones in the manual!).

Really the only head scratcher was the location of the panel inside the footwell that the engine bay harness connects to. Laying on my back (love it..) with my head jammed up into the footwell, i finally found them up on the side of the car. None of them really wanted to come out, one of them was really stubborn...

It was one of the most satisfying moments of my engine building "career".

Good luck, be patient and if you are stuck, be sure to come back and post here!

Not if they are properly set up.

If a 2 post can cope with this a DB9 which is effectively front-mid-engined should be fine.
