Those who question 4.6's longevity.

[kirkyg]

Well so far i've got 21.5k good miles on my 02 GT and couldn't be more pleased. For once i'm not worried my vehicle will strand me on the side of the road (like my dodges did ).

the 4.6L is in general a very strong motor. Someone said they questioned the reliability because theirs had to be replaced under warranty. My comment to that is what % of them are replaced? Maybe .01% which is one in every 10,000 or so. Anytime you selling a v8 vehicle for such a cheap price your going to have a manufacturing process thats not absolutely perfect. I think ford did a good job striking a balance of good reliability and affording cost with some quality control.

i agree!

my friends 2002 Z28 just chunked a rod out the side of the block with only 28k miles on it. it had exhaust(l/t, o/r y-pipe, borla) but the intake side was stock. he told me he missed 3rd and the motor sounded funny and then died..... i think he shut the lane down for the night. it's nice to have a friend with a tow-truck.

it happens to all cars. no manufacture is perfect.

Whats your experience with 4.6's? With someone with the name of 5.0's 4ever, how much weight can your comments on 4.6's really have..

My experience with the 4.6 is that I am technician at a lincoln mercury dealership and actually have more underhood time with the modular motors then I do with pushrod. I have also had three different motors in my cobra. The original motor came to a very quick death because the previous owner didn't keep up on oil changes. Second motor was a 99 version, the cam sprocket bolt going to my driver's cylinder head broke in half causing a lot damage. Third motor was another one out of another car and this one had a rod knock since the first day I started it up in my car. So know I am going to my fourth engine which I will build up with my old 96 block using forged internals and 03 cylinder heads.

I just turned 100,000 miles today while on a date. She's 4 years old and running stronger than ever. And I drive the girl HARD. Just goes to show that if you take care of your car, change the oil when yer supposed to, it will last a long time.[/QUOTE]


Holy crap, 4 years and 100,000 miles??? My mom's car is 10 years old and its only at 83,000 AND it's driven from boston to chicago many many times what do you DO with that thing?

 

[abouttobeglue]

ive got 28500 on my 03 and ive only had it 11 months. its a real estate car

 

[Modular2v]

i wouldnt use 03 cylinder heads just incase you get a set of heads with "the tick" get some 99 of 00 windsor PI heads

 

[Modular2v]

not to get too far off subject.. Does anyone know what causes the "tick" on the cylinder heads and if it causes any loss in power

This is not going to be a 2v motor, it will still be 4v with either 03 cobra or Mach 1 assembled cylinder heads.

 

[new22003]

75,000 miles on the wifes 2000 GT. No problems other than the IAC.

 

[merc123]

My 89 LX I4 had 123,000 miles on it when the tranny finally went. That was in 99.

 

[tontot77]

I hope my 4.6 lasts after the rebuild and the lower compression... what I bummer if I manage to blow it with forged guts...

 

[97rioreddohc]

My '97 started to knock something wicked after 60k+ miles, I bought the car with around 40k-something miles on it. And just finishing up putting an '01 block in it.......I don't blame the make of the 4.6 or durability of it........I blame the previous owner and the maitenance credability.

 

[98yellowgtdropt]

91k on my 99 gt which i abuse VERY hard and so far only blew the clutch.

i wanted to buy a blower for christmas but thinking maybe a bullet proof short block would be a better idea so i can build it up from there

It's my meditation. When I need to get away from the mundane, I drive. Plus I was driving round trip from Houston and Dallas (520 miles) once a month for half a year.

 

[Modular2v]

ah 5.0s forever..you're another one of those goofy DOHC guys huh? LOL j/k

 

[rx7speed]

eh nothing needing to be said till you hit the 200k mile marker like my unreliable rotary has while hitting 7-8k almost once a day

 

[Vellines]

Just chiming in on this thread - I have a 96 GT which has received all regular maintenance like clockwork and it has 106,000 and feels very strong!!!

'99 GT with 120,000 Miles, driven very hard, original clutch, busted rear end at 80K, synchros getting shaky, but still runs great (knock on wood )

 

[forpit2000gt]

I have close to 40000 miles on a 2000 gt and no problems at all. Friends have 96 gt, 97 and 98 Cobras with 150,000 plus miles shot with way more nitrous than you should even think about run very hard. One of the Cobras smokes a little but still runs strong. I have F150 with 4.6 and 150,000 + and no problems, had another with 270,000 and ran great,( wrecked)I know others that buy trucks with the 4.6 and use them as srevice vehicles and keep to 150-175000 before replacing. With reasonable maintanance they will last a long time. I am sold.
Mister 5.0 guy... I do have a van with 250,000 miles that runs great too.
BTW ..even new Hondas have some engine failures.
