Teardown 4.6L Ford Lincoln Mercury DOHC 4V Aluminum V8. Timing Is Everything!

If you haven't seen my other teardown videos, check them out here!
• Blown Up Engine Tear D...
I know I should've used a shop vac
I own and run a full service auto salvage facility in the Saint Louis MO area called Importapart. Part of our model is parting out core or bad engines.
In this video, I dismantled a 4-valve all aluminum 4.6L V8 from a Lincoln Aviator. This engine shares its design with the Mercury Marauder, Ford Mustang Mach1 and Cobra, although there are differences in material and components used. This core sat outside for a very long time which made for a rather messy teardown.
I hope you enjoyed this teardown video, there's several more in the pipeline.
Edit: We did find 4 slightly bent valves after cleaning and a thorough inspection. Thankfully these valves are VERY cheap new!

It's important when leaving an engine outside to remove the spark plugs, so the cylinders can all fill with water and rust evenly.

These engines were first released in the 1993 Lincoln Mark Viii. Great motors. 290hp and still get 27-28mpg on the highway.

[@mjbalice]

I was a son of a mechanic. I loved taking apart locked up engines my father scrapped. Something about taking a engine apart as a kid I will never forget. I still get the itch to take apart blown engines. Finding the cause of the engine to fail is exciting. Had a collection of bent rods, push rods, valves, pistons and a old snapped in half Chevy straight 6 crankshaft. Good ole days of being young☺️

[@MrJeffcoley1]

The 4.6L V8 is not an interference engine, so that's why there's no damage to the valves or pistons even though the timing chain broke.

[@trythinking6676]

My 2.2l wasn't either

[@benjamins9121]

Love my 97 Cobra. Though mine can stock with an aluminum Teskid block, the best 4v block, strong as heck and 75ish pounds lighter than an iron one. Tore mine apart at 140k for forged rods and piston for a turbo build, still ran fine and had cross hatching still. It has been a terrific engine for me

[@svtxj9921]

1996-01 Cobras used an aluminum block, only the ‘03-04 supercharged cobras were iron blocks. Also only the ‘03-04 had the forged internals, all the n/a 4.6 motors had the powder rods. Also the 3v mustang GT from ‘05-10 had an aluminum block too.

[@Moonraker11]

There is something so satisfying listening to that impact wrench...

I love watching the teardowns. It reminds me of when I used to build engines back in my 20's. I used to get some real bad ones from my local junk yard. Thanks for showing what the heads look like after cleaning.

[@JustFishing321]

Man just when I had it in my head that I would love to see you do a tear down to any modular ford engine and then boom here you are answering my unsaid request, thank you for the awesome content my man your doing a great job

[@skylinefever]

Those valve cover gaskets look like blue Fel-Pro replacement units. It would be interesting to now what repairs the engine had in the past.

[@edwardmyers1746]

they do look like the fel pro replacements LOL

[@ZacLowing]

[@davidcannon1144]

Superb. I'm hypnotised by the sound of that impact

[@bubbafats6246]

had a marauder, blew a spark plug out of the head, and threw a rod bearing. i had it at a dealer to get fixed, and my car along with 10 others all were set on fire. it was a very sad day for me, as i loved the car, but in the end it was probably a blessing.

[@jasonacheson8167]

I could watch these teardown videos all day!

[@edwardmyers1746]

Lincoln Aviator engine!!!! I just fired up my brand new one in my Aviator after working on the car for 5 months (project car), love the car, love the engine very reliable. Love the engine so much I got myself a marauder as well. I will tell you those engines are pretty chunky for their displacement. OH and yeah get all them 9 thread heads you can boy! you got lucky and got the latest DC heads in ONLY 05 aviators!! those will go for $1,500

[@CathyInBlue]

Are 05 Aviators guaranteed to have the 9-thread heads?

[@edwardmyers1746]

@@CathyInBlue yes

[@bubbadw60]

LONG LIVE THE MOD MOTOR! Those DC heads are worth their weight in gold. I buy 05 aviators just for those heads! That block alone is worth money without the rotating assembly!

I cannot believe the phenomenal job Your Parts washer did cleaning that stuff up

[@1benyko]

yesssss ray-gun noises while taking the heads off. good stuff

[@CMDRSweeper]

I don't care what engine it is... As long as it is one that has had an issue and you tear it down to find out and theorize what had happened and knowing if it was a win or a loss on the profit side is what makes it enjoyable to watch. Oh and no annoying music either is a plus! And good commentary as you go.

[@BuildaMan]

I'm pretty happy i found this channel. His engine tear downs are great to watch, but the rest of his content is also pretty bangin.

[@jackfulton6696]

I wonder why this engine was deemed unrepairable in the first place, just some timing chain and tensioner damage would seem worth it to fix imo

[@lowridersvt]

I would of tried to fix it .

[@davem5333]

Whoever had the engine first apparently didn't have the skill or the time to open it up and see what the issues were. A few new bearings, chains and tensioners, set of gaskets and a few valves, that engine can run again.

[@CaptainSpadaro]

Replacement was likely judged to be more cost effective; I recently helped out with an engine replacement on a 96 Honda Accord that we were told had a bad head gasket. We didn't verify this, but the customer was okay with paying for a junkyard motor. Put it in, fired it up, ran fine. If this had been out of a manual trans Mach 1 (with the forged crank), I suspect it might have been repaired rather than replaced; as is, this was likely out of an Aviator (judging by the throttle body), and thus there was no real incentive to rebuild it (especially when labor time is factored in).

[@brucelytle1144]

I helped my SIL rebuild his 2v 4.6, so I have all the cam timing tools for them. It should come in handy when I rebuild the 4v 4.6 aluminum block I have for my 46 Ford panel twuk. Engine and suspension came out of a 98 Lincoln Mk8. They are very repairable, with patience and the right tools. Powerful and lightweight.

[@PeeterPuncher]

These heads are also used GT500 supercharged 5.4's on 2005-2013, which is why the they are valuable. BTW these are actually pretty reliable with the updated tensioners, guides and chains. See if you can find some coyote 5.0 engines.

[@jeffreygoss8109]

Was the chain/tensioner issue fixed with the coyote?

[@wyndnra1n]

That is incorrect, 2005 was the last year anything came with a 4v 4.6 and the gt500s had the Ford GT heads which are the superior heads. But very similar.

[@PeeterPuncher]

[@LichaelMewis]

Very cool. I have a 2004 Cobra and it's got a very similar makeup to this. Difference is cast iron block, forged crank, rods, and pistons. And the cams may be different. But it's still a 4.6 4V. And of course supercharged. To give you an idea of how stout this engine is, I am running 620whp @ 19psi on 93 octane. You can get well into the 700s whp using e85. The only weak link in this engine are the Zollner pistons. Btw, would love to see a teardown of one if you ever get your hands on one.
