Hello, why do I have a little oil coming up on the passenger side at the level of the pipe equipped with the pcv. Oil is leaking at the base of the hollow carburetor at the rear. (Red Arrow) . I've had this problem since last year after adjusting my rocker arms. Is this the problem of a bad setting??

Not sure that is oil. Looks more like you are weeping fuel from the rear bowl of the Holley carburetor. I have had evaporated fuel stains just like that on every Holley equipped car I have ever owned. You can clean the stains off with lacquer thinner or naphtha.
I'd take a paper towel, or even your finger, and run it along the bottom of the seal area (where you can see the blue gasket in the picture) after the next time you drive the car, I suspect you will find that seal is moist from fuel leak. Whatever you do - do not overtighten the 4 screws holding on the bowl, you will warp it and make the leak worse (ask me how I know...). The carb needs to come off and get new fuel bowl gaskets.

Bonjour et merci pour votre réponse. Je regarderai ça lors de ma prochaine sortie.

mais je pense vraiment que c'est de l'huile qui monte par le tuyau de la valve pcv.


je te ferai savoir
