🔌 Edelbrock 4405 Signature Series Push-On Round Valve Cover Breather: Optimal Engine Ventilation Solution Review

Great case but it fell out and we lost it. Good price - we went for the cheaper clip-on version. This was too big for our application.

Will not fit standard valve caps. Gets 5 stars because it is as described. You can't blame the manufacturer for not knowing better.

Received a used breather with grease stains, fingerprints and scratches. It would be nice to know that I'm buying used and not new. Otherwise it's a normal valve cover vent. Fits well in a 1-1/4 hole.

WILL NOT FIT Edelbrock Signature Series valve covers for Chevrolet 262-262-400 '59-'86. But it arrived quickly and looked great, but I'm keeping it to try and use on another build. As this is an Edelbrock product, one would think that the description would indicate the appropriate series of valve covers.

Nice shiny Edelbrock breather cap that pairs beautifully with Edelbrock valve caps. Arrived quickly, intact, just as ordered. The only problem: The rubber mount on the cover fits very, very tightly into the hole in the valve cover. Don't plan on using this breather cap as a removable device to add oil to the engine (the way the old breather caps used to work). Once you install this breather, an act of Congress is required to remove it and the rubber bushing can be damaged. Plan to keep it shiny
