What about the other option of just having the breather hose point up rather than down and sticking a little air filter on the end of it?
Yep

Yes it's a mechanical oil pressure gauge.

I use to have it in the cab but took it out years ago, all the plumbing was there so I rehooked it up in the engine bay a couple of weeks ago.

After a while you stop looking at the gauges in a street car and with the stock low oil pressure warning light in front of you, it will tell you when to turn the engine off. The stock gauge while rather vague, back by a mechanical gauge in the engine bay to check, it works for me.

The mechanical oil gauge while not in the cabin will still let you know when you oil pressure is lower then normal at idle and with the throttle cable you can check the pressure at higher rpm's too.

I agree. I crashed my Vincent Motorcycle years ago because of oil on the road.

Noted.

I’m not a biker, but believe strongly that everyone who uses the road has a responsibility to keep our two wheeled brethren alive. Catch can it is.

Where did you get the 'T' Piece from to split the senders?

Daily drive is a Giulia 2.0 MA, wife drives a 939 Spider in the summer and a Abarth 595 in the winter. For special sunny days we have a S2 Spider Junior in the garage.

Speedway Motors or Jegs, not sure but either one would carrier the fittings and ss hose.

Lovely Machinery!

Sometimes I suspect there are a few members lurking on the BB who are just looking for opportunities to show off their awesome engines!

As well, I hasten to add, to contribute knowledge and wisdom to the discussion.

To take this discussion a little off topic, I wonder how many members are aware of issues with Gasoline Direct Injection (GDI) which, because the port injector is no longer present to continually wash down the the intake tract and and back of the intake valve with that fine, high-detergent, Tier 1 fuel we all use, can result in really messy situation. And no, fuel additives are not any help, since the gas in GDI never enters the intake plumbing.

Ford Ecoboost engines were among the most troubled, with misfires and poor fuel economy presenting in as few as 10k.

Of course, we need not be concerned about hot, turbo-boosted air or Exhaust Gas Recirculation (EGR) in our 2.0L, but I'd still be concerned about putting valve cover blow by, along with acidic products of combustion back into the intake manifold and crankcase.

Hey, wait a minute!

That's exactly what our oil vapor collector (OVC) does, until it gets so clogged it begins to pop the dipstick. That's how I discovered mine was blocked. Now of course, it returns fumes to the intake and recovered oil back to the crankcase.

Guess it's no big deal.

Back to GDI, I did some research on the new Nissan engines, and they include a port injector on each cylinder to provide cleaning, while the DI works to improve performance and economy (as well as, unfortunately, particulates.).

Also drove a GDI Hyundai Limited recently and while the salesman was stumped about how they mitigate intake fouling (no port injector) a knowledgeable service rep said they recommend a $180, chemical intake cleaning every 15,000 miles. How many owners are going to let that problem fester till it becomes more than a nuisance, only to discover their baked on crud won't respond to chemicals and needs mechanical cleaning (walnut shells?) often requiring pulling the heads (!) like I've heard some BMWs need. (Hmmm, think I may need a question mark here )

Oh well, no free lunch...

Now I'm gonna go back and look at those beautiful engines!

Happy New Year all!

Though maybe not as bad as DFI but our little twin cam is pretty notorious for carboning up too.

Yup. When I bought my ‘08 Audi S6 (first gen direct injection) I factored a $1500 intake cleaning into the price. They blast the back side of the intake valves with walnut shells. The before and after pics are amazing. It was gross.

As you point out, port injectors are coming back to address the problem. I wouldn’t buy another car with the 1st generation tech. This particular car was bought in a moment of weakness. It fit my budget, was my favorite color, had white leather (!) and a freakin’ V10. It’s for sale if you’re interested

Got it! Demon-Tweeks in the UK, the packaging does have the profanity VW-Audi on it, sorry about that.

It would soon be drooling oil from up there...

Catch cans are not that expensive (or at least, they can be had for reasonable prices), and just as easy. I drain my catch-can back to the oil sump

50 years from now - how are we going to restore a "classic" microprocessor based modern car?? Alfas - 1980 Spider, 1987 Milano, 1976 Spider

I used to use an old plastic oil/brake fluid/etc. container with a few breather holes drilled in the top ...
