There is really no reason to. Unless a car overheats enough to warp the head, there is no good reason the head gasket should fail.
Only if you have a lead foot.
it all depends if u think its worth it i just rplaced the head gaskets on my 94 t-bird it has 160,000 miles i just love the car it is a long process it took me about 7 hours to do it myself if u do plan on doing it ur self make sure u get a mechanics book and read about replacing the head gaskets the gasket kit will cost about 65.00 dollars but it includes everything u need so good luck
the biggest problem these engines have is lower intake manifold gasket failure. this is because gm used nylon gaskets and the anti-freeze eats away at the gasket as the antifreeze gets older. LIM gasket service life can be extended by flushing your cooling system every 2 years and keeping up with cooling system maintenance. another thing i have heard is they have head gasket problems. now i don't really believe this because my mom's boyfriend has own you Buick Skylarks with this engine and I now own a 95 Chevy Corsica with that engine as well. One Buick had 138,000 miles before we got rid of it and the other had 195,000. Both of those engines had the original head gaskets in them. my corsica only has 44,000 miles on it so i can't say much about it yet. but i can say that head gasket failure can be avoided by maintaining your cooling system as i stated earlier and if the car starts to run hot pull it over before it actually over heats. i replaced the oem 195* thermostat with a 185* thermostat to reduce the engine operating temps in my Corsica. And one more problem that alot of GM's have is piston slap. there is a website out there called www.pistonslap.com that says that piston slap is this terrible thing and all that, its really not. remember the 195,000 mile Buick I talked about? it had it since it was bought at 60,000 miles and it ran fine at the high miles. piston slap really is harmless, its just a noise. so if you keep up with the cooling system maintenance and the car your looking to buy has already had the LIM gaskets replaced...the engine is a fantastic engine. i love my Corsica that has it and I loved driving the Buick's too. It really has some get up and go. Head gaskets and intake gaskets are to of the big problems with the 3100 but their is also the problem of the camshaft breaking
7,926.28 miles
i believe it was 94 miles
189,000 kilometers = 117,439.155 miles
The furthest i went was 32 miles.
about 90,000 miles
What year? If it's between 2000-2002 I'd say around 5-6k if it's in good condition with no mechanical defaults.
Depends on year which you fail to list.
when to change please - # of years, # of miles?
23 in the city and 30 on the hwy.
if the miles on the engine aren't too high, then just replace the head gaskets. if the whole engine is tired go ahead and swap out the motor. its a lot cheaper to do the gaskets then to buy a new motor.
With low miles (40k to 70k) and stock heads/gaskets 8 lbs max. With low miles, better heads/gaskets, arp head bolts maybe 10 lbs max. Higher miles, not more than 6 lbs.
If it isn't rusted away I would say yes, Jeeps really hold their value well and you can easily get you money back years from now.
The timing belt on a 1999 Acura Integra should be changed every 75,000 miles. Once over the mileage limit there is a chance the belt will fail causing engine failure.
Expected mileage for a 2000 Integra is 25 mpg city 31 hwy. These are basic guidelines. Due to hills, weather and individual driving habits actual mpg figures vary.
