Collapsed PCV Hose - '94 Accord EX
1994 Honda Accord EX
I just noticed that the PCV hose was collapsed while idling, as if there was a vacuum on it and the walls of the hose were not strong enough to hold the vacuum. I will replace it and the PCV valve. What kind of problems can this cause? Thanks, Gary |

Does your PCV valve connect to a hose that goes down the back of the engine, through the intake manifold web? If so, the oil separator box may be sludged up. If your PCV valve is the sort that connects to the top of the valve cover, then the valve cover baffles may be sludged. Check for oil in the intake hose and the throttle body. You may simply be using an inadequate PCV hose, such as an aftermarket one. Is the PCV valve aftermarket? Aftermarket PCV valves can have incorrect flow rates that can cause other problems. -- TeGGeR® The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ |

The PCV hose had seams on it and it appeared to have collapsed along those seams. The interior of the hose was not clogged or oily, but there was an oily odor and evidence of some erosion. I replaced it with 5/16" rubber fuel line hose. The PCV valve was aftermarket and there seemed to be considerably more "rattle" in it than the OEM replacement. Thanks, Gary |
