Default PCV upgrade on '59

...separated a new thread from this one.

- there is excessive smoke coming from the oil fill opening
- there is excessive smoke coming from the pipe that leads from the back of the block/intake to the undercarriage along the exhaust
- both smokes were there even before I overheated, before the first ride
- an exhaust smoke 'disapears' after few minutes (and only the 'two places stated above' smoke remains)

...

Thank you Gary. Can you please briefly explain what is the road draft system and how difficult/expensive the service could be? I found great info about the PCV here on the web. Do I get it right that the PCV would solve my problem without the need of the service? Should the valve be exchanged every year as it gets clogged in time? How difficult is the exchange and where the parts for it can be purchased? Does any list of needed parts exist? Do both variations work the same?

Also they say that one way from the four-way brass connector goes to the vacuum booster of the fuel pump. I have an el. fuel pump installed on my bird instead of the stock one. Is it a problem for the PCV upgrade?

No.

The upgrade is fairly simple and is detailed here-

Yes, that's the link I found - they say one of the ways from the brass connector goes to the vacuum booster of the fuel pump...

Do both variations from the link work the same?

PCVs are pretty easy to check to verify if they are stuck open or shut. And they are cheap.

All you are doing with this modification is "closing" the system; you are essentially "capturing" crankcase gases with engine vacuum, and sending them back through the engine (and then out the exhaust pipes).

The system will be detailed in your Shop Manual (or if you don't have a manual let me know and I will send Ray the info to be posted)..

Service basically is keeping the oil filler cap cleaned and open to draw fresh air into the engine. If the filter becomes plugged to the extent that it cannot be cleaned, it needs to be replaced with a proper service replacement.

The same filler cap will be used on a PCV conversion (Open System) or fresh air can be drawn from inside the air cleaner (Closed System). The closed system is also more emissions compliant in that engine fumes cannot be introduced into the atmosphere (fumes being burnt inside engine). It all depends on the final look you want.

Default Heat Riser Valve

Today I found my heat riser valve not working properly. Or I should say - not working at all . After the engine was warmed up, the valve stayed in the closed position (on the picture) and there was a sort of clicking sound from the engine. It wasn't stuck, when I pushed the valve down/open, the sound disappeared. Without the push, the valve returned to the closed position. Can this part be repaired anyhow or it needs to be replaced for those bloody $70?

Update: I just got back from the shop manual where they say: '...the valve is designed to open when the engine is at normal operating temperature and operated at high rpm.' That is something I did not test. Still, they also say '...a properly operating valve will open when very light finger pressure is applied to the counterweight.' The pressure was not very light at all...

More-less for cosmetic reasons, I decided to go with the carb spacer instead of the four-way brass connector. Can you advise if this solution will have the same effectivity? Here is the parts list, hopefully nothing is missing in it:

'65-'68 oil cap with open/emission
air cleaner adapter (any idea where to get one?)
road draft replacement connector from a 1962 to 64 Ford
(any idea where to get one?)
'66 carb spacer
PCV valve
hoses

I think that on your year BIRD, that the later PCV carb spacer will cause clearance problems with the air cleaner to hood clearance. The one you are showing (C6SZ 9A589-A) has a nipple for a vacuum signal, not large enough for a PCV signal.

This conversion-

...Has the PCV inlet as part of the carb base.

The other conversion method shows using the brass vacuum fitting on the intake manifold-



You will need a push-on oil filler cap (open) as opposed to a twist-on to fit the oil filler tube properly.

Here is a Y Block PCV file Gary asked me to post for him.
