I get way too much condensation in my gen IV 502. I'm thinking a pcv valve would help. Any way to install one? Stu |

"I get way too much condensation in my gen IV 502."
Ayuh,..... A PCV will Not cure that,....
Going out,+ running the motors up to temp, with a load on them will clear it up in No Time......
You'd need to find a Vacuum Port to put 1 in..... |

I could be wrong but I don't see an open vacuum port as a USCG legal option...anyone clear that up? |

Sorry, Bondo, but you're wrong here: a PCV will remove moisture, and no 4 stroke marine engine should be without one. Moisture plus oil contamination equals acid and slug; and there's a LOT of moisture in the marine environment!

Just Running a motor, up to temp,+ for Awhile will Dry the oil out as Well......
That said,....

One needs to find a tap in the carb base or manifold, run a hose to a PVC valve, the put that valve in a hole in a valve cover. Also, there has to be a breather to allow air to enter the motor, sweeping away the moisture that is TRAPPED there.
It won't go away on its own, parner.

Well, I went to the autozone. Of course I had to tell them that it was a 454 in a 3/4 ton truck, but I got a pcv valve and the valve cover grommet. My intake manifold had a plug, 3/8 npt, so the hood up was easy. Now I'm running slight negative pressure in the crankcase. We'll see how it works. Stu |

Well, the pcv setup seems to work fine. Whereas I would get a bunch of water out of my breather if i shook it now it is bone dry. Also no condensation under the filler caps. I'll continue to keep my eye on it. Stu |
