Two questions here. First, What is the correct type of assembly lube I should use to install seals. I've seen two kinds, one that looks more like a heavy grease and one that looks more like a liquid. What's the difference, and what are the correct applications for each? Second, What is the correct type of torch to be using on frozen bolts, etc... on a car. Mapp, propane, etc...??
As long as the lube mixes well with oil, you should be good. I've been told that white assembly lube (forgot the base, lithium?) will harden and crust. I'm going to be using redline assembly lube on my engine, but you really only need assembly lube where metal comes into contact with metal. I am going to use some rotella-T 10w 30 for my main/oil pump seal and call it good.
Mapp gas I believe gives you a hotter flame for a little hand held like the ones form HD i go witht eh yellow bottles which I think is mapp
You also shouldn't use MAPP in a torch designed for propane, but you can use propane in a torch designed for mapp. The mapp torches are typically swirl types. MAPP has propane and acetelyne, and maybe some other stuff, which is why it burns hotter. Most store stock I've seen has been replaced with something called "MAPP2" and I'm really not sure what the composition of that is.
So basically get a nice flat dish - like a baking pan - and dump some good ol motor oil in it and then dip the gaskets/seals in it just prior to installing. Lube being mainly so the gaskets/seals don't catch, pinch, and tear?
^Thats one way of doing it. IIRC mainseals and such come with some sort of lubercation already on them, but it never hurts to finger some oil prior to install.
