Flash Posted August 22, 2020 Share Posted August 22, 2020 Hey All, I'm in need of some educating. On my inlet manifold there is what looks like the standard carby insulator block which has a short piece of rubber pipe attached to it. My first thought was that it is some kind of vacuum pipe, but when I look at the insulator more closely there doesn't seem to be any holes on the interior wall, so to me it looks like this pipe leads to nowhere. Anyone got an idea what this pipe is for ? Ta in advance. Quote Link to comment Share on other sites More sharing options...
a.craw4d Posted August 22, 2020 Share Posted August 22, 2020 Can you blow through the pipe? Quote Link to comment Share on other sites More sharing options...
Snoozin Posted August 22, 2020 Share Posted August 22, 2020 This goes to the breather on the rocker cover on a 4K, assume similar? Quote Link to comment Share on other sites More sharing options...

Flash Posted August 22, 2020 Author Share Posted August 22, 2020 Thanks for all of the input fellas. I hadn't thought of blowing through it so good call there. Gave it the quick lung treatment and the air comes out of a square slot at the opposite end of the spacer that I hadn't noticed before, so looks like the spacer has some air galleries built into it. Snoozin, I reckon you are spot on, rocker cover breather it must be. Thanks again everyone. Mystery solved. Quote Link to comment Share on other sites More sharing options...
ajg193 Posted August 22, 2020 Share Posted August 22, 2020 That hose goes to the PCV valve. Other hose from rocker cover goes directly into air cleaner assembly on top of carb. What engine is it for? 1 Quote Link to comment Share on other sites More sharing options...
