I have had random water in the oil in my KS (milky residue visible inside the oil filler cap) and I heard about this stuff. Ya add it into the coolant and it apparently seals cracks in blocks, heads, head gaskets, radiators, heater cores and welsh plugs. Has anyone heard of this stuff? And if anyone has, would it really do what it says it will do? I added it in today and drove around a while, and haven't seen any water in the oil as yet.

Yeah.. Seal-up is the stuff I am trialling.. so far so good. Just seemed too good to be true when I saw it. lol

Doesnt last THAT long though, ive had some people come back and say that its only lasted a few months whereas a few have said its lasted over 18 months...

That's alright.. I'll just be happy if it lasts a few months.. 9 bucks a bottle can't go wrong!

It says on the bottle to drain the coolant and Seal Up after half an hours driving.. but some people recommended just to leave it in there until the milky residue re-appears. Does this sound alright?

Most ppl I know don't bother flushing it out again, just leave in there.

Some guys (4X4 offroad fellas) even put it into their rads when they're perfectly good
as a precaution when going bush. If they go water fording they change the engineoil asap.

condensation is all it is. Nothing to worry about. Quite common when we get cool nights after a warm day

Used that stuff in my old TS radiator, worked an absolute treat!!! :D
Not a permanent fix tho, you could be just delaying the inevitable if there is something wrong with it.
