Hello ozvolvo brains trust!

Does anyone know where I can get a vented cap like the one from Yoshifab? By the time I factor in shipping, this thing will cost me about $200!

Making one by using a bulkhead mount -10an fitting and an early steel oil cap from a 240 shouldn't be super hard.

Otherwise 100 series and the like have a 5/8"(?) pipe that comes out if the top of the oil cap.

Hey thanks guys. I don't mind making one if there are no other options. I have the steel caps from the 360s valve cover and I could definitely make something work from that, but the things I create never turn out as nice and usually cost me just as much in time and energy.

I am really just wondering if there is another option to buy something like Yoshifabs creation?

Are you using a 530/531 head, or an earlier 160/398/405 head? If earlier, I have a B21 valve cover with breather outlet.

Ok. So, not having any luck sourcing another company offering a vented valve cap, I decided to make my own. Actually, I made two...

Here's how I did it:

02 sensor extender - m18 x 1.5 thread and 37mm long.

M18 1.5 to AN10 banjo fitting

Welded onto cap and primed

Hole cut out of oil cap lid + painted

Just waiting on the banjo bolts to arrive. I personally prefer the banjo bolt setup, rather than a straight pipe or vertical fitting, because I have about 50mm of clearance between the bonnet and the oil cap in the 360. I will post a photo of it all together once I'm done. I had to pay for my machinist friend to weld the 02 sensor extension on, which almost doubled the cost of making them! But each one cost approx $55, not including my time. $35 in fittings and $20 in labour.

Looks really good! I can MIG weld at home and have a bucket full of the steel caps, maybe we should go into business!

    I am always open to going into business with like-minded individuals. But ah, maybe something more sustainable 😏

    Here's the links to the fittings if you wish to do them yourself?

    I also ordered one of these, but I might just be using a straight an10 hose connection that I have here already.

    Thanks for the links, for -AN fittings and everything related, there is an Ebay seller in the UK called torques_uk who has good quality fittings at low prices, I've bought a few things from them before.

    @Angus242164 No worries. I just checked out that seller on eBay. Very impressed with their postage rates and prices! I'll keep them in mind when I need my next fix. Thanks!
