Is a blown head gasket fatal?

I own a 1999 Jeep Grand Cherokee Laredo I6 and have a cracked head gasket. I leaked tons of coolant into the oil and had it replaced and sealant added, which seems to have done the trick. I was told that because I ran it with coolant in the oil, it would delubricate the parts and eventually cause my engine to break. Am I driving a ticking time bomb or am I safe. Thanks

It should be fine as long as you got it changed and it still runs the same.

Coolant contamination does slowly eat at the bearings. Not critical if you get it fixed soon... but not something you can just ignore.

I would do another oil change or two after 1000 miles to try and get every bit of the coolant particles out of the lubrication system.

X2, I would do an oil change every 500 miles for the next 5 oil changes.

It really depends on how long you drove it with coolant in the oil. The shorter time the better. If it ran a long time with coolant in the oil, you really want to do a bearing job soon.

There are lots of cars on the road that have had their head gasket(s) replaced. You should be fine, take the advice already given to you and keep that oil changed. But do have your heads checked out by a good engine shop before you put them back on. Something caused your head gasket to fail. You need to fix THAT to prevent THIS from happening again.

Sorry didn't read it well enough I guess. You have already had it replaced but what do you mean by sealant added? I hope you don't mean like that block repair crap because that stuff is horrible on your cooling system.

I know what caused it. My relay switch went bad, causing my radiator fan to not work, engine overheated. And the repair shop put a liquid that goes into the gasket, and hardens up to fill the crack. I hope this isn't bad for the rest of the car but it doesn't leak antifreeze into the oil anymore. And the head gasket itself has not been replaced as I don't have the money to do so. But how often should I change my oil now?
