thank youMy 97 Mustang overheated and now has water in the oil, does that mean a new engine or can this be fixed?
Do not drive your Stang, you most likely have an intake gasket, or head gasket puking the glycol (antifreeze) internally. My suggestion to you would be to tow the vehichle to your local shop , and spend 60-70 bucks and get a proffesional diagnoses. If they find either the intake or head gaskets puking you will have to take of the plenum, remove the intake and possibly the head and take them to the local machine shop and get it checked for cracks or warping. If they are warped they can be machined, if it or they are cracked buy new ones. This is not a job for a novice. your Mustang deserves to have a pro work on it. In addition to the intake or and the head gasket being changed you will need to have the coolant flushed with an exchange or flush machine at least 2 times. If there is coolant in your oil then there is going to be oil in the coolant system also. , Change your plugs, wires, and you might as well change the cap and rotor while you are there, the plenum gasket, the distributer shaft o-rings and paper gasket should also be replaced, new t-stat and gasket, put it all back together get the oil changed add a quart of Lucas oil. drive the Stang about 500 miles and change the oil once again. This is not an inexpensive job to have done, expect to pay between $1000 to $1800 to get this job done right. Get it done the right way and you should not have the problem again as long as you flush and maintain your coolant system at regular svc times. As a service advisor with 12 years experiance I see this problem a couple of times a month. Hope this helps James H.My 97 Mustang overheated and now has water in the oil, does that mean a new engine or can this be fixed?
yes i would agree with James H years ago i had a buick v-8 drove it to work had to go out out to move move it started it upit puffed like a cigar shut it down pull the dipstick same thing water got into the oil cracked block gt. Report Abuse
Replace the nylon washer on the oil plug. (you dropped it somewhere)
Refill the engine oil, and change the filter. ($20).
Refill the cooling system, and drive the car around the block a few times.
If it runs OK, and doesn't make any funny noises, replace the head gaskets, and have the heads serviced. ($700)
If it runs like crap, and makes a bunch of noise, sell it for parts.
The cost of repairs will exceed the value of the car.
Pull the heads and check them. You either blew a head gasket or warped the heads.
Last pair of rebuilt heads I bought for a V 6 Ford was around $169.00 each so it will cost you around $ 338.00 + which you doing the work yourself; depending on the cost of the heads some run more than the others.
You've could of just blown the head gasket or worse warped or cracked the head if you have water in the oil. You head maybe be refinished if possible. Or it might need a new head all together. I can't say for sure because I can't inspect the vehicle.
hmmmmmm
Replacing engine is the best solution but
Try to find what's the cause of overheating for example if it's the blocked radiator then your new engine also will be coocked soon if it's clogged thermostate or dodgy water pump then it's worth to change the engine.
I don't think you can use your old engine parts to your new(used) as it overheated.
Wow, what else could go wrong?
.
It sounds like the engine bought the farm, so don't try fixing it.
.
Why?
.
You overheated the engine for whatever reason, while on the highway at highway speeds.
That engine got really hot, and it seized up, and an engine stopping suddenly is finished.
Which is why you couldn't restart it, it was so hot the parts all expanded and got gooey inside.
The bearings and journals have been damaged beyond repair.
The cylinders are now out of round.
If the engine seized real quickly, the rods could be bent or twisted.
The heads are warped, maybe even cracked, though you might not see the cracks without a black light and some dye.
.
Water in the oil? Even for 10-15 minutes water can do a lot of damage to an engine because water can't be compressed.
So if water gets into the oil pump it ruins the pump, hot water becomes steam and steam creates pressure which blows out seals and erodes metal.
,
Then theres the problem of loose bits of metal and scale and stuff now laying around. Who's climbing inside to clean it out?
Do you get the picture? It's a lame horse, so bite the bullet and bury it with honor. Trying to fix it will only result in more problems down the road.
.
Check around for a used engine, or a ';long block'; and make sure you get a warranty in writing.
.
You likely have a leaking head gasket like all the other posters say and indeed the water may cause the bearings to sieze. This will happen quite suddenly. This engine, even if repaired, will never be the same or a good chance it will not run right or the head gasket repair will fail again. I would be looking for a good low mile used engine. Or donate the car and get a new one.
your motor will need a rebuild sorry water in oil is bad news basically you have shot your piston rings for cost wise a second hand motor will work out to be cheaper than a rebuild in the long term you have to decided what you will do with the car sometimes you can buy a sick second hand motor and have to pay to have it removed and replaced
Sounds like you cracked a head. It is repairable at a cost. Avoid running you engine until it is fixed or it could lead to more serious damage, like spun bearings.
Possibly a blown head gasket/warped cracked head.
Hopefully, the lower end is still good, this is fixable, but costly.
Don't drive it till its fixed.
No.
maybe
This means that you warped the cylinder head, and coolant now leaks into the crankcase and mixed with the oil.
If you dont drive it, you won`t have to rebuild the WHOLE engine, but you DO need a rebuilt head.
Welcome to ';Newer car'; world.
hi,,,, by now you are very sure the engine blew the head gasket..based on what everyone is saying.. and they are correct. but what you should also consider, is that the engine could also have lost compression. meaning, even if you have the head rebuilt, and a new head gasket, you are still dead in the water. engine will not run when hot.. it might stall when operating temperature is reached. I recommend a stock ring replacement also. just so you dont have to do the job twice. good luck. p.s. the engine block needs to be trued also, making sure the surface is flat for the new rebuilt head. if this is not done, engine will blow head gasket in no time.. a complete rebuilt engine is a sure fire, compared to a used new engine taking 50 50 chances....
don't chance it - buy a new one
