Catch Can and AirRaid Jr

Finally had a nicer day up here in Calgary to get my catch can and airraid jr kit installed. so far, so good :) .

I used the L-bracket method to secure the catch can to the strut bar supports. Gave me a good excuse to purchase a table grinder - rounded out all the edges for a clean look - painted it a nice black. Wish I could find the thread that aided as a walk through for me. It helped plenty.

I'd like to remove the engine cover and give the engine a good clean. Is there anything I should note when doing this? I have to drive a few km to the car wash - is that far enough to worry about engine heat + water cracking anything?

Thanks for looking!

Looks good!!

As far as cleaning the engine, thats been my major concern lately. The hot engine and ice cold water hitting it sounds like trouble to me. I'd be interested to see what others recommend for cleaning the engine bay this time of year.

You are pretty safe as long as its not hot. Wait until the Jeep has cold down just dont get carried away with detergents and water by the electrical stuff, coils, etc... I detailed cars for 15 years, these new motors are pretty safe for cleaning with being careful around obvious parts. After you're done let the Jeep warm up completely to dry excess water before driving it and DONT GET CARRIED AWAY WITH ARMOR ALL!!! Armor all acts as a conductor for electricity when over used, can shorten battery life and other things. Ive been doing it this way for years with out issues. Post pics when youre done!!

From the Google:
During engine operation, blow-by gases, as well as oil mist from the rotating components of the engine, pass through the PCV valve and are routed back into the intake for the engine to burn off. However, some of the oil mist and other products settle along the engine intake and over time form a "gunk." The oil catch can collects the oil mist and condenses the fuel vapors while allowing "cleaner" gases to be passed back into the intake.
Through various threads, and pictured evidence (especially for the HEMI engines) I determined it was a must have addition. I'll be reporting back as to how much she catches in the next little bit.

Catch Can is the best investment for a Hemi. Mine gets a couple tablespoons every 5,000 miles or so. CAI's are a waste of money though; the throttle response is noticably worse than with a stock intake, and all that noise gets old. Much better investment is ported TB, which works great the with stock intake.

I would agree with you on the CAI, however the AirRaid Jr. can be classified more so as a short ram intake. It keeps the factory air box, I have a 'performance' filter, and I like how it cleans up the front of the engine bay. And to be honest - I don't think it sounds any different than the stock.

I think I've only got 50km or so on the catch can, so we'll see what happens in 3000km with my next oil change. dmsfun - what ported TB would you recommend?

I have the airaid intake tube with the stock box and kn drop in filter. Looks so much nicer than that stupid oversize resonator. Performance wise it hasn't really done much for me, and doesn't sound different either.
