Hey mudders. Just thought I’d ask for some people to weigh in on this. I’m not one for snake oils or quick fixes. I am not suggesting this is a remedy for any maintenance or getting around fixing a real problem ie head gasket or putting new rings on pistons. I was wondering if this would be worth experimenting with especially since it’s incredibly rare to find any 80 series land cruiser with less than 150k miles. I searched the forums and nothing came up. If there is a thread out there my apologies. This is the YouTube link that piqued my interest.
