| Post subject: | Metal PCV part number? |
Hey, who can tell me the part number for the metal PCV I'd need for an '85 225 with an '81 head? I've been having trouble with the plastic ones making noises that made me suspicious, then after replacing the existing plastic valve with another one (the first one snapped while being pulled out of the valve cover and I got another plastic one because no one around carries the metal version) and immediately got oil blowing out the tail and obvious blue smoke on the freeway. I don't know why the metal works better, but it had one on there when I bought it and the two plastic ones I've put in since then have both failed me. I know I have major heat issues, but I'm sort of stuck with that right now while I search for the most affordable solution to fixing my rotted radiator and get it together with putting a heat shield on my carb. I don't think these plastic guys can stand up to the heat. So, what's the best valve to go with here? |

http://www.pentastarparts.com.au/sunsho ... earch]=pcv Should find one on there alright in those pages of results, they will ship to the states (Probably where the product comes from anywhere). I have been buying from their online store for years and have always had 100% satisfaction and service. I think if you fix the heat problem you won't have a problem with the PCV. Hope this helps. |

You can do as Brussell suggests and import a PCV valve all the way from Australia if you really want, but plastic PCV valves are still better than just fine, no matter how many separate threads you ask the question in. |

Sorry Dan, I have a brain disorder that makes it difficult for me remember details and keep things sorted out, which is worse when I have to do things on my phone because I don't have a computer. Sometimes it's just easiest for me to ask a question again. My Dart is my only vehicle, so I drive it wherever I go and I can't afford to replace the radiator yet, so I just have to do what I can for it when I can. I've had a lot of issues with people getting the part I need wrong because my car is mixed and matched, so I just wanted to make sure I got it right. |

So I put on another plastic valve and it's still rattling. I've been reading around about noisy PCVs and from what I've seen, I can suspect that I may not have enough vacuum, or keep buying crappy valves, or about a thousand other things that people think might cause a rattle. I know my car runs way too hot. It's the major problem. I have the original radiator on there and it's as rotten as it gets without actually leaking. I also don't have anything in place to keep the carb cool. I've only had the car five months and have spent most of my time and money working out the daily issues of keeping it together, so I'm slowly working up to a different radiator and better carb protection. I have some questions and thoughts: The air cleaner is gone and there's just a four inch or so exposed filter plopped up on top of the carb, which is a Holley 1920. Between the fitting that the filter screws down onto and the carb, there's a plastic ring that I'm assuming is basically just a spacer of sorts to fit the filter to the carb. It has a notch in it that I'm guessing is to let in air from somewhere and there's a small hole in the top ring of the carb that'll line up with it, but can also be mostly blocked off by turning the plastic ring. Make sense? My question on that is, why is that hole there at the top of the carb and should it be blocked off? Is it meant to accept something my car doesn't have? I'm going to order an AC Delco PCV. I believe it's #CV761C. The one I had on there before the current one, broke when I was pulling it out of the valve cover. I found what seems to be the metal piece which is supposed to block or open flow in the valve laying in the driveway. It's kind of a rod shaped thing. The valve on it now is the same kind (can't remember the brand) and they've both rattled terribly. Do some PCVs use a rod inside rather than a ball? Lastly, I don't know how old my breather cap is, but it looks pretty clean. Could the breather blocking up cause problems that would add to my PCV issue? Thanks everyone for helping me out! |

Ha!! So then, while just checking things out, I notice the vacuum hose going to the distributor has apparently been melting slowly and collapsing. Does this sound like what could be causing my issues? |

The hose to the vacuum pot on the distributor is going to affect timing, which could be the source of the rattle you report. Suggest that all vacuum hoses be checked for leaks, cracks, and fittings. I've never heard of vacuum issues or timing to cause a motor to run real hot. Doesn't mean it can't, just means I've never heard of it. Suggest flushing out the radiator before cold weather hits. Playing around with water in near zero weather is no fun. |

It runs hot because the radiator is about dead. Luckily, I live on the beach in southern California, so it's never too cold or hot. The weather is just perfect for it. Any other temp range and my car would be damn near undriveable. The heat just makes things worse, like heat soak on a warmer day. Would anyone have an idea of what hose should be going from the carb down to the distributor? I don't know if there's a specific type. |
