Guest glaureglin Posted February 28, 2005 Share Posted February 28, 2005 ...that runs from the bottom of the stock '78 Intake Manifold to an outlet on the (looking towards the front of the car from the drivers side) left side of the engine? It looks like it has two different sized ends. I need a new one (old one deteriorated), and have NO idea what it's for, if I need it, or where to get one...

datsunlover Posted February 28, 2005 Share Posted February 28, 2005 I'm thinkng you're talking about the PCV valve hose? It's hard to see, but it hooks up just in front of the exhast maifold to a 'pipe' sticking out of the engine. Quote Link to comment Share on other sites More sharing options...
Guest glaureglin Posted February 28, 2005 Share Posted February 28, 2005 Yeah... what on earth is it for? And where do I get one? Quote Link to comment Share on other sites More sharing options...
Guest 73Turbo240z Posted February 28, 2005 Share Posted February 28, 2005 it it's the PCV hose he mentioned before, it stands for positive crank ventalation... it vents the buildup of combustion pressure that can develop in your crank case from blow by on the pistons, it also keeps you from blowing seals out and thus leaking your fluids all over. Definately a good thing to keep cleaned and in proper operation. Some people put breathers on them and let them vent to atmosphere, but i recommend you just replace the hose as it is in there now, leave it hooked up, it will reduce the any smells your car puts off, and it's better for the enviroment i'm sure.

Nismo280zEd Posted February 28, 2005 Share Posted February 28, 2005 if your running EFI keep it on as it will affect your idle if you remove it. I run carbed and have my valve cover vented and the crank case vented. -Ed Quote Link to comment Share on other sites More sharing options...
