stop leak recommendations

[wesalexleft]

Can you please recommend a good stop-leak product for a 2003 4.6L V-8 Mountaineer with about 120,000 miles on the clock. It's leaking coolant into the oil. No codes or white smoke from the tailpipe. It's losing coolant when the pressure exceeds 13LBS at the degas bottle as confirmed through a 24 hour pressure test. No outward signs of how the coolant is getting into the oil. It's my son's college truck, and he's away in college now. I've been trying to diagnose it for some time now, but no luck. The value of the truck has lowered to the point that a teardown fix for heads, etc outweighs the benefit of the repair, so I'm willing to give the stop leak a try if it will extend the life of the truck another year or more. Over spring break, I plan to give it a shot, as well as try once more to find the leak without removing heads, etc but so far that has proven fruitless.

Thanks,

I would personally never use any type of "stop leak" product, even in an emergency or as a last resort.
Of all of them, the Alumaseal brand seems to get the most positive results. Do some research and GL.

Thanks. Like I said, this is my "last resort" option. I was hoping someone would be able to suggest one from personal experience that had helped them get down the road a good while longer. From what I understand, the manufacturers are using them from the factory on some cars now, and I'd hoped that the technology had gotten better than pepper, eggs, and ginger.

From the 2003 Ford Explorer Workshop Manual

The addition of Cooling System Stop Leak Pellets VC-6, darkens Motorcraft Premium Gold Engine Coolant from yellow to golden tan.

I used the Bars product on a leaking main seal once and it seemed to slow it down pretty good. I think they have a good head gasket product also. Probably won't hurt to try it since the truck is at the end of it's life anyway.

Has some really good reviews:

You could buy Ford Stop Leak pellets.
I've used them when my intake manifold was leaking. I put 2 of them on my coolant reservoir, let it run for a while then flush it.

you could buy them at the dealership for $5.00.
