The 4.6L & 5.4L are Great engines so long as you/the owner checks the oil level every couple of weeks, and don’t go an extended period of time without changing your oil filter! These motors are stout, but as anyone who has repaired them knows, the plastic timing chain tensioners are the most common failure in these engines if they have ran low on oil. And the plastics on the intake manifold are known to break around the thermostat & cooling Passover, but they fixed this design in 04 I believe. And lastly the infamous 3 threads of aluminium that hold your spark plugs in the cylinder head. (Also fixed in 04 by changing it to 8 threads) *specifically I’m dating the engines used in the mustang, so others like the f150 and CV may have gotten the improvements before or after the dates I mentioned, but just wanted to share my experience with the ford modular lol.

I enjoy watching these old school videos. Reminds me of auto class

My favorite Ford Engine. Crown Vics, F150s, and Mustangs used this.

I own 4 vehicles with this engine. Love this video.

Thankyou for uploading this

I feel like I'm ready for an engine rebuild now. Lol

THANKS this tells me everything about my 95 Vic.

Hell-fkn-yes!! Exactly what I needed!🤘

Great video. While you have the engine out, and especially when you have the timing chain off, replace those old steel freeze plugs with good brass ones. I had the plugs behind the timing chain rust out, dumping copious quantities of coolant into the motor oil! Previous owners evidently didn't believe in anti-freeze, opting to run straight water. Several exposed freeze plugs were plugged with JB Weld.

thank you for this video!!!!!! amazing work

This is fantastic I've seen half of this but it's awesome to see the whole thing that's you for uploading this.

Who is here trying to rebuild there 2v?

Very informative about the engine type. So much has changed since the 289, 302, 351, 390 and 400ci years.

Thank you for sharing.

Thanks for posting. There Are so many videos with contradictory info. This official video sets the record straight!!!

Wow, what a cool video. Very informative!

Wow wish I would of came across this sooner a lot of good information thanks for posting this.

1990 cant believe this engines been around 30 years

thank you very much for sharing this treasure

Thank you for the video, i enjoyed it, own 2 4.6 s currently, one is,almost 300k miles on it, runs great ,both do .seen lots of these come in the shop over the yrs .i like em

They say the left handed jack screws are to be turned counter clockwise to loosen, but in fact are to be turned clockwise to loosen.

Very thankful thumbs up

Used to have a 99 gt with the pi 4.6 and a 4r70w Was always amazed at how it could run up hill in overdrive at barley over 1000rpm and still be smooth as hell Gm’s ls is honestly a better design but for the time period the 4.6 cane out it was honestly really good for something from fomoco Makes sense the Lincoln town car needs a smooth power plant and the 4.6 fit the bill like none other for the time

6:30 he says "the screws have left hand threads and turning them counter clockwise loosens them." That would tighten them on left hand thread

I got a 4.6 2v with 309k and still going strong .

1:05:00 Ford seemed to have bolt knowledge down to a science, too bad navistar didnt take notice with the 6.0L , and I learned something new about adding 2 to the number of lines to find out what grade the bolt is.

These dudes were working on a brand new lab rat Towncar back in the day. Must’ve been easy to work on a brand new car; no rusty exhaust bolts, or dirty hands, due to aged gaskets and seals!!!

Need one of these for the 3 valve

I wonder where the 150 HP for the 5.0 came from in this video at 3:30 ? Early 90s Mustangs with the 5.0 made 225 horses with half the size of a 4.6, when i say size i mean physical size,if you ever wanna see something amazing look at a picture comparing both engine and their sizes,its crazy how big the 4.6 is!! I'm a old Ford guy and i have and currently own both versions 5.0 and 4.6, until i owned a 4.6 i never realized how good 5.0 engines (302) are,the 4.6s can jump timing (it has happened) they have the issue of the passenger head not getting enough coolant, the fiasco of the intake cracking,the issue of engines being built in different plants and being built differently,(lunacy right there) so if you have one and wanna put parts form the other you are screwed,yeah it can be done but its inconvenient,the issue of spark plugs blowing out of the heads, yeah 5.4 do it most but 4. 6s do it also, the list goes on and on. I have a Thunderbird with a 4.6 a and also a Mustang with the four six and another Mustang with the 5.0 , i love all 3 and not knocking the 4.6, just stating some facts, not something "i read" but things that have happened to me and to friends that also own it, what i like about the 4.6 is the smoothness of it,its not that hard to work on it and they will last a long time with proper care and they are hard as heck to blow a head gasket on them,this is a fact, not hearsay, i think the "torque to yield" bolts and the entire torquing sequence on the heads contributes to the head gasket being so resilient.

56:08 this car must have been a prototype (test mule because the production cars the air intake read " V8 Over Head Cam " and on the lincolns it was painted an argent color

Had an 09 with the 4.6 3v swapped for a 5.3 stroker

I’m trying to rebuild a 4.6 1998 Ford Mustang vin number x I got the kit but I didn’t come with the seal retainers where do I get the retainer

my best video

Is there a modular 4v video?

Those are some anenmic looking main caps, even if they are cross botled.

Wasn't it at TDC to begin with?

Did Mike Rowe himself narrate these?

(Panther Platform)

Goldmine

I just bought a Mustang with a slight rod knock, it's almost like KZfaq knew it...

Lol. “High horsepower”

Is this what I have in my 2012 ford E250 cargo van?

😏

the 4.6l v8 in my Explorer was a fucking pos. The heads were garabage.

Torque to Yield bolts suck!

I noticed a lot that wasn’t done that by 2020 standards is a must when building and engine but hey if the fuckers who made it say u don’t have to check any bottom end clearances fuck it, no degree on those camshafts I’m doing it too..crank endplay was the only measurement taken I believe but over all good material

lmao they couldnt recegnize this was a shit design? that is so sad! lol problem free with pcv routed through a plastic intake gasket?

😏
