Big waste of $$ or decent move for longer engine life?

I had threads replaced due to bad seals and in order the speed the process/get me back on the road quicker I opted to have the shop install take off heads/valves, new seals instead of machining my own heads.
I'm almost to 100 miles where I need to check the amount of oil in he can.

Do you think this will use more fuel since it's not reburning the old oil?

Mods: relocate the thread if needed.

 

I have one and its great. Keeps a ton of oil/water mist from getting back into the intake and heads.

 

How often do you need to empty yours? After 120 miles there's barely anything in the bottom.

 

I have had one for years. I can go around a year or longer without draining mine. It works great and keeps those new heads and intake looking great on the inside.

I rather have clean air than oily dirty air!

 

I empty mine every time I change my oil.

 

Thanks guys

 

Has anyone run these in a cold/cooler climate? (where you might experience below freezing temperatures for weeks at a time)? Any issues with the cans at that point? I've been toying with the catch can idea since I tore my motor down and got a look at the amount of oil residue in places I wouldn't normally expect it (at least, not for the mileage I had at the time.) Anyway, sorry to hijack, hope its all good!

I don't exactly have the weather you guys do, but I have had zero problems over the last 3-4 years I've had mine on. And that has included some pretty cold weather for here in VA.

 

Bingo! They are mighty effective as I had one on my 04 gto. It takes about 3 minuets to empty so do it every oil change.

 

what catch can you all running?
