I've boiled water in one of those..Lexan is pretty frikin durable. I'd say it's better off than 99% of the plastics under your hood.

 

Hmmm, I might have to check that out then...thanks.

 

Nalgene also sell Poly bottles and canisters..which I WOULD NOT recommend. They melt very easily. Lexan is the way to go. I have a nalgene that goes everywhere with me, unbreakable!

 

I would highly recommend using a metal catch can, as some plastics will not react favourably with the fairly nasty fuel/oil/exhaust gas combination you will be pumping through it.

A trick to maximizing oil recovery in your catch can is to pack it full with steel wool or scourers (i really mean pack lots in and tight). Also place your inlet and outlet hoses as far apart as possible in the can. You will be amazed at how much oil builds up in there, especially with older engines.

 

one thing that hasn't been mentioned is that you don't want to simply put a filter on the hose like some car guys do.
this is a no no

you want a vacuum, i've seen gains of up to 30hp by putting a vacuum pump on the crankcase.

 

The all trac guys recommend that plastic not be used. I am not sure why, but all of the catch cans I see made are out of metal.

Someone on alltrac.net posted pics of a Hyundai power steering reservior and it seems to be working and there are plenty of Hyundai's in the junk yard.



I like how it looks stock, no bling bling here!



If I like how this mod works on my Celica, I am going to do it on my 4Runner.

 

on the 3sgte engine, those little filters get clogged up fast.

Explain what you mean by a "vacuum pump"

 

I drove over one to test out the theory... held up really well both capped and uncapped. I'm convinced

 

THAT'S R&D! Actually, a long while back I had left milk and cereal in my Nalgene for about 2 months (whoops). I simply could NOT get the smell out of it. So I drove over it with my Pathfinder until it broke...then exchanged it with a new one. Durable things!

Thanks, I have never heard of that before. Those suckers are expensive!
