01-24-2007, 12:15 AM

It's weird ,but, I have 2 SC's both are 1990s 1 is auto the other is 5spd 1 was abused the other wasn't.They both blew head gaskets at 116,000 and change.

My '89 popped the gasket when it was my daily driver. I was 2o years old and a lowly E-I-Owe-You-1 in the military. Couldn't afford to keep putting money into it every other week, so I cut my losses and traded it for a Ranger. That was 8 years ago. I think the car had just about 100k on the odometer. It was a 5 speed.

To my knowledge as the previous owner stated one of the sides blew and ford repaired it under warranty. Not exactly sure how many miles but probably not many if it was still under warranty. Anyone know what they came with for warranty???

I've taken out 2 headgaskets so far.

93sc - 160,000km - (96,000 miles)

94sc - 240,000km - (140,000 miles)

I've got two SC's, a 90 and a 95. Both have around 98,500 miles. To my knowledge they have the original head gaskets.

09-18-2007, 12:04 AM
never, knock knock knock

09-18-2007, 06:26 PM
I have a 92 and 90. I blew them both with quite a bit of mile on them.

09-18-2007, 10:10 PM
i have a 92 they poped at around 75k or so bought the car with 64k about a year b4 they poped have owned the car for almost 3 years

09-19-2007, 04:36 PM
I plan on replacing the head gaskets in my 63K engine befor I drive it one mile.

So (hopefully) I will never experience this special event.:cool:

09-20-2007, 10:13 PM
91 with 65k on it all grandma miles.


09-22-2007, 03:47 PM
The orignal motor had 149k and the original gaskets just no oil pressure. The replacement {used} 1991 motor had 78k when the head gaskets started leaking water outside the block. Never overheated and no water in the oil it just looses a quart of coolant every few months. Still driveable and dependable I just dont like leaks of any kind.

09-27-2007, 03:58 PM
Just shy of 200,000. I thought that was pretty good. Then I added some goodies and blew them 5,000 later. That was pretty bad. oops:rolleyes:

04-13-2008, 11:58 PM
87,000 miles under idle after running hot once.

04-14-2008, 03:04 AM
im wondering if the lower mileage sc's that blew were original coolant or not flushed as often as supposed to!!

04-21-2008, 10:44 AM
mine didnt exactly blow, i just replaced them before they went and did some other things while the heads were off :D

179,331 miles

04-22-2008, 11:30 AM
Just bought an SC a few months ago, had 103k on it. now has 107k and blown HG.... also i blew the HG's in my 96 3.8 LX.. i'm 2 for 2 for 3.8l thunderbirds.....

10-19-2008, 02:08 PM
I just blew mine at 153000. funny part was when doing the compression test to see wich side blew, they all passed with over 150 psi. I was expecting to see a little drop at least. pulled both sides and it was passenger side cylinder 2 and really close on 3 as well. oh well while iam in there might as well change some more parts


10-19-2008, 07:45 PM
on my 94 auto... 130k miles on the original, gramma-driven headgaskets... still ticking. had a few close calls when it was acting up and overheating, but she's alright now... will update when it happens. lol.

10-31-2008, 06:56 PM
I never blew one.....Err I jinx myself?

11-01-2008, 06:36 AM

I said that once too and not long after my 90 looked like a insecticide fogger going down i84.

03-10-2009, 07:59 PM
1992.197,000. miles changed them after the shootout last year.

03-10-2009, 08:39 PM
blew the gaskets on my 90 after running it hot really hard on the interstate

@ only 39k :eek:

still drove fine and didn't loose any power but just wouldn't stay running cool

06-19-2009, 04:23 AM
I have an '89 5spd with 89,600 miles on it. I'm crossing my fingers that it holds up for a while. Any suggestions to make it last? :D

06-27-2009, 12:47 PM

1990/85,000trying to beat a honda would not go over 95 ka bam , then dreaded white smoke

08-22-2011, 09:50 AM
Mine blew at 116k

12-31-2012, 01:41 PM
Is there a way to prevent head gaskets from being blown?

Or at least is there a way to get a little warning so I can do something before they blow?:eek:

Watch the odometer. Expect them to blow somewhere between 80,000 and 120,000 miles. Nothing says you have to wait for them the blow before you replace them.

Ive had my 90 xr7 since 06 and mine jus blew a lil over 100k yae for me 😂😂😂😂😂

Drove from Prescott Valley AZ to Camp Verde AZ, over the mountains, just an hour's ride, with the AC on. Came back with AC off because it was almost pegging the gauge. No smoke, just runs hot. Drove 4 miles today, lots of pressure, foam from the radiator (with cap off, just idling) then pulsing gyser. No coolant in the oil and no visible leaks anywhere from the radiator hoses. Am interested in the best parts to repair the heads. Go Ford or Alternatives? Marty

Had 2 89s blow at 150k.

Now that I have a few more supercoupes I suppose I can include them in here as well

black 90 5spd - rebuilt engine split the crank due to improper radius, head gaskets were fine, no tellin when the originals blew
red 90 5spd - about 39k on the rebuilt engine and they let loose on I-10 when I was beating on her, she got hot due to a coolant leak
blue 92 5spd - casualty of testing, I was paid to blow them at about ~70k, let loose on I-55 due to running lean (testing purposes), new rebuild free of charge
titanium 91 auto - blown at about 120k, driven like it was stolen its entire life
orange 93 auto - grandma blew the head gaskets at ~130k driving from south carolina here to new orleans, she wasn't watching the temp, possibly a stuck thermostat to blame
black 94 5spd - crapped the gaskets at ~110k when the potential buyer came to test drive it :eek:
92 titanium auto - crapped the gaskets at 110k for no apparent reason

my other black 90, my red/black 90 and my 95 purple auto all had the stock gaskets before i rebuilt the engines with no problems at 180k, 90k and 120k

all 10 of them now have arp heads studs and all except for my 92 auto have mls gaskets, knock on wood I have yet to blow an MLS gasket
