[4S50]

Does anyone have any experience that they can share in using liquid head gasket repair such as CRC Fiberlock, etc. in a 3.6 Jeep?

The only head gasket repair is a head gasket.

KSeal is real deal it works. I have used it on a Tundra and it totally solved the problem. No bubbles coming though at all normal temperatures.

I’m sure it did, that is its purpose. Only takes a little bit to “seal” a leak. The rest just floats around having a jihad with the rest of the cooling system. Its favorite victims are heater cores and cooling packages. There isn’t a more critical gasket on any engine than a head gasket. If any part of it is compromised then it needs to be condemned

There is no snake oil that will fix a head gasket that is junk . That shit will clog everything except the gasket leak . Do it once do it right . My 2 cents

Have you ever used it?

Before you do, watch some vidgas of it. Those products are made to plug holes. And they don't care what hole. If it can plug it, it will. Then when you have to do the repair correctly you've got to dig nasty goop out of everything.

No I have not or anything like it. I do not endorse “mechanic in a can”. Using it can potentially and likely lead to progressive damage

agreed, just cus you stopped the leak on the outside doesn't mean you stopped the one developing inside either. Once, the gasket fails at one spot, its failing elsewhere too. I've never had a Head gasket leak in only one spot. I'd bandaid for a ride home or to the shop, but not long term.

I’ve used it. It works with no side effects.
sure if you have the money and the engine is in good condition otherwise replace the head gasket. There is potentially and likely reasons not to replace and k seal would be your best bet.

Yep it’s not worth it. Expensive and put your ride down but better than gambling with a crate engine.
