does anybody run a catch can on their 2nd gen 4.0 v6?

Don't need one. Its a Toyota. Keep the oil changed regularly and keep up on regular maintenance and it'll last you a long time!

 

3rd gens had a thread for catch cans helping stop engine issues on steep climbs.

I've been running one for a couple of years now and love it. Once you've seen the amount of oil/moisture that comes out - you'll be surprised! Yes, one more maintenance item to keep track off but who needs to have an excuse to have a "cold pop" and contemplate life when you're draining your catch can.
Just hate to have this "gunk" being sucked into the combustion chamber and being burnt off - just seems wrong.

Enjoy
