Question Guys with aftermarket valve covers...

...how'd you deal with the fact that the oil filler breather hose is 5/8" but the nipple of the valve cover breather is 1/2". The result is too much slack to be taken up by a hose clamp.

I was expecting a direct fit when I bought these valve covers. What am I missing?

These are the Ford Racing cast covers by the way.

Not sure if you can find a hose 1/2" on one end and 5/8" on the other, but try a 1/2" hose and heat the one end with a heat gun to slide it over the 5/8" breather.

Or take a 5/8" drill bit and drill one end bigger if the 1/2" hose is thick enough.

I have tried that before!

It didn't end well!

You need something like this here. They come in alomst any combo you can think of. You can get a 5/8" to 1/2" reducer pretty easy.

+1 on this with a bit of extra hose... or increase the nipple size with silicone repair tape.

Well, I no longer feel like the only idiot that thought of that and found out how quickly it doesn't work.

Just change out the breather cheap $6 and easy...Mr. gasket makes a one with a larger 5/8" nipple, I ran through the same thing with the ford racing version breather that came with my valve covers from ford last year...
