74 1.8 oil breather and fill seals/gaskets, Need help with gaskets needed - Free Seals for all from McMark Options

[J123young]

Need your help please .......so I purchased a new cork gasket that goes underneath the breather box. looks like someone put gasket seal where the filler neck bolts on to the breather box. where can I find this seal? having a hard time finding the right one. Also the breather hose, what size it. Does anyone have a list of all the gaskets and the hose size? Where to purchase them. Don't want to order the wrong ones.

Do you not own a tape measure? (IMG:style_emoticons/default/rolleyes.gif)

But maybe you don't realize your filler neck is from a 1.8 L-Jet 914. That is the least common setup, and the factory documentation is missing some details on the later engines, specifically for things like that hose size. So maybe you're thinking that hose is the same as everyone else on here, but it's not. A minority of people have that hose and even fewer know the size off the top of their head.

Give us all a hand and take a measurement to get us started and if you put in a little work, maybe everyone else will be more willing to help you out.

Looks to be I/D of 7/8 and 11" long (IMG:style_emoticons/default/smile.gif)

Yup, 22mm. But even the old ones seal up decently with a hose clamp on each end. Looks like you have one, just grab another.

The 22mm hose you can find but it's pricey. I believe it was Sierra Madre that had it. Or Pelican.

There are of course, a few gaskets and a spring inside the cap, too. If you look carefully at the inside of the cap, you will notice that the center is really a breather. Air/oil mist would travel up through the center of the cap and out the side of the inner cap, where the spring resides. The lower gasket on the cap keeps the oil from splashing up to that hose you have, making sure it goes through the center of the cap. The upper gasket on the cap keeps the system sealed. You should have both seals or you'll have more oily residue travel through that hose to your throttle body than you'd like.

And while you're at it, but one of 914Rubber's airbox to Throttle body hoses for the 1.8L. They're great, supple (instead of the rock hard piece that's in there now). Keep the metal tubes sticking out of the old elbow though, you'll need to reinstall on the new piece. Many of those elbows are a source of vacuum leaks on the 1.8L, and usually underneath close to the TB, where you can't readily see it.
