I had the JLT catch can and even with the brillo pad add in the catch can was a complete waste. It still let all the oil through and did not keep it out of the intake. I run breathers now and have for about 20k miles or so. I change my oil at 3-5k just like I did before, I check my oil often and it always looks fresh.
07 gt, CMS cams, hurst, CAI/tuned, LT's, o/r h, m80's, FRPP mani, UDP, lowered with steeda 1.25/1.5, exedy mach 400/race flywheel, 1-pc DS, BMR upper/lowers, 4.10's, CHE brace with TL's, and a few other things that dont add up to much.
