Valve Cover Breather

SKU: ZZ-VCBRTH-V2

$29.99 Sale price

Regular price $29.99

This valve cover breather that simply replaces your factory twist on oil cap on your valve cover. It is beneficial for cars that do not have a PCV system that can keep up with thier engine. This will fix the dreaded dipstick popping up issue. It does this by venting excess crankcase pressure when it builds up. We have been told that people have been seen power gains and lower oil temps after installing it. This update version of our valve cover breather only stands at 2.75" tall so it fits better in tighter spots.

This is a simple one piece design, other venders breathers make adapters to mate to an aftermarket breather. This one is made based off of the factory oil cap and includes a sealing O ring.

PCM programming required, since it is venting your crankcase and disabling your PCV valve.

Fits: Cobalt, Ion Redline, G5, Pursuit, Regal, Grand Prix, Bonneville, Park Ave, Impala, Monte Carlo, LS v8 (Corvette, Camaro, Firebird, GTO, G8), and many other GM vehicles with a single alignment pin valve cover.

DOES NOT fit Cruze/Sonic, or ATS/CTS/2.0 Camaro (LTG engine) due to a dual locator style valve cover. 
DOES NOT fit Sky and Solstice because the engine sits too far under the firewall.

Works well on an untampered valve cover

I used this to replace my old breather. Over time the heat was chipping away the bottom. So i bought this new one. However oil keeps spilling from the top. The o ring isnt as thick as oem. But more than sure it will work on a normal valve cover. The part that screws in is messed up on mine. Simply used rtv gasket to make the o ring thicker.

Great product!

Ordered and received within 2 days! Easy fit! It is a little loose but still snug! Had to move charge pipe because it was a little in the way but fit's in perfectly! Great product!
