Can someone tell me what size for the PCV hose and can someone explain to me the function of the second hose pictured(right), thanks

The second hose is a modification, judging by its small size, it won’t be doing much. What is it connected to after the rocker cover?

[jimk]

Where does the other end of the hose shown connect to?

[scatman75]

Connected here

Do you have idle problems?  

 

That is a vacuum leak. That fitting on the inlet manifold should be sealed off. It was from a long abandoned exhaust gas recirculation system. 

 

Get a catch can with a couple of input barbs to terminate the large stock breather hose and this add-on smaller one.

I do have some vacuum issues which is why im chasing down the problem now, do they sell a plug for the manifold, and ill just replace the valve cover and run a catch can

Find some 5/8" oil rated- hose.  (that's not trivial...)

 

Connect the big nipple on the valve cover (which has a purpose- made baffle already done)

to the port on your air cleaner.  Waa-Laa, all good.

Use a generous length of hose, as the hose itself helps separate oil and vapor...

 

And plug that other thing.  And, the other thing!

 

And support the faq (FAQ store above) and buy the block- off from here!

Toby - “oil rated hose”.... mmmmm... I just hooked up my shiny new catch can setup with 5/8” coolant hose. Without pressure or too much heat is special oil- rated required for this. 

 

Put another way how does oil affect the coolant hose rubber..and how soon?

 

Thanks for extra details
