I INSTALLED A NEW V12 ENGINE INTO MY ASTON MARTIN DB9

- In this episode, a new engine finally arrives from overseas for my Aston Martin DB9. It needs a bit of work before I can fully assemble it and fit it back into its cradle in the car.
For any enquiries, you can reach me on my Instagram - itsalexbaldwin
I would replace all the plugs and coil packs as these are a service item and a big job to do with engine institu. Also a good clean of the manifolds would have been advisable prior to installing the gaskets. Good luck.
Would definitely be checking the main bearings too, also check condition of oil pump and for £500 I’d be putting on a new one, new plugs too, they are service item. Did you manage to check the bores out? Fair play to you for doing this, got some balls mate, well done. I reckon you paid £2500 for engine
It’s all looking a lot better. As others have said, those bearings on 11 and 12 look shockingly bad but the crank looks reasonable. If the wear is coming from a failure to prime the pump after a long period of not running, I will definitely be turning mine over on the starter without firing up after winter. Good luck with it and look forward to hearing it run.
Haha learn from others mistakes! I’ll definitely be priming the pump before the first turn of the key. Cheers mate, me too!
According to @Bamford Rose the primary cats on these are prone to disintegration - may be worth looking into manifolds!
I’ll do a bit of research on this tonight!
@@itsalexbaldwini’ve seen the cats being extracted out of the headers. they fall apart and grenade the engine. worth checking into.
It's becoming more and more common... you only have to look at the mk2 Toyota mr2 to see why everyone removes the primary cats on them. It's a no brainer. No cats, no worries + 40bhp 😄
Great work ! Can’t wait for the next video. 👏🏻👏🏻
I do admire your commitment to getting this back up and running, but like others have said that the bearings shouldnt need replacing at such a low mileage. The white metal part of the bearings are ripped up as if it was an oil problem that caused it. Did you actually check any of the main bearings especially the ones furthest from the oil pump. I would also check/ strip the oil pump to check that any of the white metal debris isnt internally there and prime the pump with fresh oil to allow it to immediately pump when you turn it over , before starting it. Also fill the oil filter with fresh oil and lightly oil the rubber seal to prevent the seal picking up on the block casting. Its a big job and I thought I saw rust in one of the bores on the scope you showed , which probably means it was left with that cylinder with the valves open for a period of time. I would lightly mist the bores with oil and manually turn by hand. That is unless the rust is bad and it will leave pitting in the cylinder walls , which is not good news.
Thanks Justin for the detailed comment, I appreciate your help. So the engine was stripped and inspected by the company I bought it from and they have shared their findings with me in a report (before I bought the engine!)
Great point about priming the oil before trying to fire her up, and I had thought of this too. I’ll make sure there’s sufficient oil pressure as well! I did oil the oil filter seal lightly, sorry the Timelapse doesn’t show it as the pan was out of shot.
Thanks again!
That is the right call imho! Keep going, can’t wait to see the finished product
A hero thank you and good luck
Well done mate great job
Cheers John!
I would replace the crank seal also on the timing cover. When it leaks it is a nightmare.
Haha, sounds like you’re talking from experience!!
Full engine normally some 9 to 15 K Euro. Your steal is probably 5 to 7k Euro
possibly barum engines
That’s a clean engine Alex, good luck with the instal. My guess is £3k
Thanks Lewis! Sadly a bit more than that haha, maybe I didn’t get such a good deal 😂🤪
Great to see you back Alex.
I reckon you’ve paid £2.5k for the new engine after your exchange. Let’s get this show and car on the road 🤗👍😎🙏
Cheers Roger, great to be back! Exactly that, putting it all together as we speak (bit of a puzzle haha)
I’ve got a sneaky feeling you’ll do a great job. I 💯 wish I had a unit and be able to afford to ra The work would be so rewarding when you get them sorted but most of all turning the key. The feeling when you’ve done all that work and it fires straight up price. Thanks for sharei
Great video... how many miles will the new bearings last for... will you be able to do anything with the old engines or are the to be turned into Coffee tables...
Haha I’ll try to do little things to help them out such as letting the engine warm up before driving it etc, hopefully last longer than 20,000 miles that way 😂
So one engine has gone off to be exchanged, the other is in bits and listed off for sale as parts (except the block which will become a coffee table!)
On a 20,000ml.engine i wouldn't be expecting to replace the big end bearings,it would suggest to me there is something else wrong !!!
Yeah I’ve been trying to think what could cause it:- perhaps someone thrashing it whilst engine still cold or oil starvation?
I have seen this many times, it's caused by leaving the engine for a long time and then starting it up without priming the oil pressure
@@daxxr2532 ahh interesting! Like if it’s been left in the garage on a tether charge over winter, then the first start in the spring?
Exactly
Wear you saw could also have been caused by failed pcv valves allowing oil to be sucked into inlet manifold - at the throttle bodies (as you saw evidence of in ur video). Oil gets burnt off in engine without any clear indication in exhaust. Oil level keeps dropping leading to starvation. Know issue with AM V12s of this era is oil level warning is set too low - with damage occuring considerably prior to that. It's why these AM V12 owners are advised to check the oil level (on the dipstick) every few weeks. Good that u have replaced the PCVs. Great video Alec - keep them coming🙂
I'm surprised the big end shells are worn at that mileage?
I agree tbh - I’m yet to see a DB9 engine with good bearings yet though. An Aston specialist told me a couple months ago that these engines burn through a litre of oil per 1,000 miles. It’s just a theory, and probably a bad one haha, but I suspect the oil wasn’t topped up by the previous owner enough
Engine after renovation? It's a bit too black inside. Pray it doesn't rattle after a few miles. Good luck.
It’s not been renovated mate, pulled out another car and inspected! I will be praying and crossing every finger and toe I have! Thank you
Low-mileage DB9 engines aren't easy to come by and are definitely not cheap. I'm going to say £7200
Agreed - next time, I’ll definitely make sure an engine is lined up for cars I buy like this first. You’re the closest to the figure so far!
I was thinking 8k 🤔
@@davidcooks5265 wrong side of Phil’s guess!
£3500
I cringed a bit at your first forklift attempt to get it onto the engine stand…glad you put slings around it afterwards.
Hahaha sorry my man, it wouldn’t be one of my videos without a bit of cringe or controversy in though - would it?! Thanks for watching even still!
@@itsalexbaldwin I enjoy your videos very much! Keep it up, looking forward to your progress!👍🏼
thats a lot of wear for 20k miles either there is another problem or its done a lot more miles. how is the oil pump did you replace it? I think you are bit too trusting of an engine supplier who is in another country.
Thanks Mike - yeah I probably am guilty of being too trusting, the engine has been seen running fine though and sounded normal. 🤞🏼
£4300 at a guess.!
Well done pal , super impressive, I bet 4500 quid.
Cheers Rick! Little more than that 👀
I think….you paid TO MUCH….🤔😄😉
😂 uh oh
£1200
Blimey Barry, that’d be some deal! Haha
