Post headgasket poll

OKAY Y'ALL i need some information quick or well when you get the time now i know we all 3.8 owner's know that are headgasket goes out sooner or later . . . . . . . . .why am i asking y'all this? well at my school there alway's some [email protected]# who think's he know's everything and this one guy is that person i mean he say's that he love ford but at the same time disses them then i was talking to someone about my car and this person but's in and say what kind of car. i told him and then he say's ooohhhh you better keep away from those 'cause of the head gasket then he asked for my milege . again i told him then he say's you'll gonna have to replace them soon. . . . . . . . so i need to know something and if you feel as though i'm being a bit too personal . . . . i'm sorry . my question's are: what milege did your head gasket's go out and if you went to a shop how much did it cost to have them fixed or if you did it at home how long did it take?

P.S. i have over 138,000 mile's should i be looking forward to replaceing my HG soon?

The actual mileage they'll fail at seems to be quite variable... mine have 124k on them in a '93.

A lot of info here http://forums.tccoa.com/showthread.php?threadid=5545

Holly cripes, you are a driving failure waiting to happen right now!! Mine went out at 129k.

Was an extremely involved process to replace on own. Don't F%ck with it, just pay to have it done.

I didn't understand a thing you said. But I'll tell you this, I took a '91 Cougar to 193,000 miles before I had the head gasket blow, many of them miles were hard miles too.

i for got to mention it's a 1990 so there's a chance that they've already been replaced right?

My 94' went at about 98500. I went ahead and had the whole thing rebuilt. The kit cost me I think it was like $725.00 with new oil pump, cam, lifters, bearings, etc... and all. Another $500.00 for my mechanic friend who did all the work. I don't remember what the machine shop cost were but it wasn't much.

My went at 91,000 hard miles, cost: $0 (ford covered until 100,000miles) , was my fault they went too (car overheated due to Fan Control Module, I pushed so that I can get home and it happened),

Car: 1995 Thunderbird 3.8

Mileage when gaskets went: 97,000.

Symptoms: Spontaneous random overheating regardless of fan operation.

Had then done at Shop? No. I fancy myself a half-*** mechanic.

Cost to get them done? $-360.00 Ford paid me to do them, after I was reimbursed under the recall campaign. (But don't tell anyone I said you can do them yourself... It pisses people off )

1995 LX Electric Red 3.8, K&N intake, Reinhart Chip.

I'm selling many 1960's Mustang and Ford parts. Have a rebuildable 289, an FMX trans, complete 67 coupe body with glass - send me PM.

I'd rather have a 5.0

1991 154,xxx and I replaced it myself for less than $50 I paid for the head bolts and the head gasket kit that came with upperintake gaskets I didn't need but, used anyway. The head was still true. It was the passenger side head and it was the cylinder closes to the firewall.

Mine went out at 206K. I guess I was very lucky to have them last as long as they did, according to my mechanic. It took them about a week to do it. Of course I had the heads sent out to be pressure tested and machined too, which took an extra day, and well worth the $150 in my opinion. The total bill came out to $968.

My first set blew at around 120K miles I didn't realize it until the steam had etched a groove between two cylinders. My "new" engine has 225K on it and is stilll going strong. Yup that's right folks, my '88 Cougar has almost 350K miles on it (many of them hard miles too) and is still runing great. BTW, the tranny is bone stock origional with just fluid and filter changes every 50k miles. Just FYI, the digital speedo recycles back to 00000 every 100k miles.

151,000 - almost 152K - and still going. But I think my days are numbered. It takes about a month, but I've been loosing a small amount of coolant. And now there's an odd smell I get sometimes. A warm smell like something is burning. I'm hoping that I last the winter and next spring they go so I can park it and start looking for a donor car. Plus then maybe convince my parents to let me get a Ranger for a daily driver so I can really have fun with my 'Bird.

I'm crossing my fingers that I'm close to home when they go so if I do have to drive, I'm not too far from home. Or else close to someone that can pull/trailer me home.

The gaskets in my '92 went at ~100,000 miles. I had no time to replace them myself. My mechanic used Fel-pro. They were not warped, but they were shaved and replaced. I now have ~70,000 miles on the Fel-pros.

The 94-95 3.8's were the bad ones. These are the ones that blow before 60 000 miles my brothers's had 220 000 km (135 000 miles) when it went. Mine has 185 000 km and is still running.

The SC's have a better head gasket that is less susceptible to going like a NA 3.8

Replacing the gaskets is a joke if you have even mediocre skills. Buy the Fel-pro SC gaskets if you do. They have a stainless fire ring that will outlast conventional gaskets. Also, get rid of the "Torque to blow my engine up" head bolts and get some ARP studs. They do not stretch or break and have ten times the clamping force.

Here's a couple of threads that might answer your question. The bottom is beefier with less restrictive exhaust.

Don't Wait

I tried waiting until I got money to do the job right. Well, it would have been cheaper to just go into hock and do it than what I did.

My gaskets blew at 150K and 70+ miles from home. I'm still borrowing the wife's minivan to get to work. It cost me about $200 just to get home and get the car to where it will be fixed.

Melon, learn from me. Change them as soon as you can. I had some of the same symptoms.

REVISED INFO!!!!!!!!!!!!!!!!!!!!!!!

well she's at 141,032.8 mile's no leak's no smell of anti-freeze no anti-freeze in oil crank. but liten up on of my instructor's who worked on alot of engine's told me today why our hg's go out alot sooner.

the reason is ford made bolt's that would'nt stay on tight over a period of time's the bolt's would lose there strenght and that what cause's the hg's to go out early ( and also i don't know if it' true do any of you know.) and i was at this one web site and one person stated: "the '89-90' cougar's seem's to have less problem's as for headgasket failure's and tranny problem's" and to be honest thank GOD and knock on wood (knock knock) i havent had any tranny or major engine problem's.

Cougar,
Yes that is true. They are called Torque to Yield bolts and are the biggest mistake anybody rebuilding a 3.8 can make.
That is why I posted this:

"Replacing the gaskets is a joke if you have even mediocre skills. Buy the Fel-pro SC gaskets if you do. They have a stainless fire ring that will outlast conventional gaskets. Also, get rid of the "Torque to blow my engine up" head bolts and get some ARP studs. They do not stretch or break and have ten times the clamping force."

A replacement set here would have cost me $60 Canadian. I got ARP head studs for $165 from Summit Racing. There are 2 different sets available. The 153-4001 ($102.69) are hex nuts and 153-4203 ($113.39) are 12 point nuts.
