Hello welcome to this week's video from Mart's Garage. When I built this French Flatty I tried a very simple PCV installation. But it is noisy. I think it is because it is mounted vertically. In part 1 watch and find out if simply adding a 90 degree elbow to let it sit horizontally will quieten down. In part 2 I tackle a stubborn exhaust stud. Will it come out by welding? Or will it need drilling? Will I break a tap? Who knows? Who cares? It's all going on at Mart's garage. Thanks for tuning in, take care and I'll catch you next time. Mart.
Nice job on removing the broken stud. I always learn a thing or two from your videos. Thanks Mart. Jim
Mart, always enjoy your adventures, problem solving and comments as you work. I may be mistaken but perhaps the PCV valve may be installed backwards. My reason for saying this is I believe the threaded ****** end goes on the crankcase fumes source and the hose ****** end goes to the vacuum source. This could be the reason for the noise it is making. Just an observation...
My understanding is that this particular valve is designed to pull vapours towards the threaded end. I got the info from a thread here on the hamb. It a 64 Chevy 283 fitment. I don't know if the fitment below is factory but it does show the orientation. In the second image you can see a direction arrow. I specifically wanted the threaded fitment to avoid using rubber hose under the manifold.
Mart - Well, as they say: "Often mistaken, but never confused." I should have known that you would not have installed the valve backwards. Still, I enjoyed our conversation. Take care and keep them coming. John
V100 about $6.00 I have one on my YBlock and on the center carb of a 3-2 unit on a 302 GMC 6. Both work great.
